Abstract:

The influence of coating layer structure on both physical and printing quality of the paper was studied. Different coating layers were obtained by changing the ratio of polyvinyl alcohol adhesives and silicon dioxide pigments in the coating formula. Then the structure, physical properties and ink-jet printing performance of the coated paper were measured. The influences of coating structure on physical properties and ink-jet printing performance were evaluated. The results showed that as the ratio of adhesive increased, the coating porosity decreased; the average pore diameter increased at first and then decreased, but in general tended to decrease; the initial drop contact angle increased, which testified the stronger hydrophobicity of the coated surface with higher adhesive ratio. The average pore diameter has a negative linear correlation with paper roughness while has a positive linear correlation with air permeability. The larger the average pore diameter, the greater the density values, as well as the better tone reproduction and the larger color gamut range. Average pore diameter also has a weak correlation with dot area and dot roundness.

Abstract:

The influences of the paper properties on ink-jet printing quality are very complex. In order to predict the printing quality quickly and accurately, it is necessary to establish a mathematical model and an evaluation system, based on which we can estimate the paper used for ink-jet printing is suitable or not. In this paper, five kinds of ink-jet papers with different properties were chosen, and the properties including brightness (X2),gloss(X3),roughness(X4),air permeability(X5) and absorbency(X6), were tested; then ink-jet printing in the same conditions was carried out and different printing parameters were tested, including solid density(D),dot-gain(DG),print contrast(K)and hue(H). Through combining analysis of each single printing quality parameter with some paper properties by using PCA of SPSS, the correlation functions D/DG/K/H(X2, X3, X4, X5, X6) were obtained. Meanwhile, a comprehensive function Y(D, DG, K, H) involving the printing quality parameters was achieved through synthesis data processing of SPSS. This study shows the influences of paper properties on the printing quality parameters and their corresponding weights, and it also proposes a prediction model of paper printability, which can provide a theory reference for printing work in ink-jet printing.

Abstract:

The article investigates the surface and optical properties of calcium carbonate paper obtained at the UzbekChinese enterprise Fergana stone paper company (Uzbekistan), in order to identify the possibility of their use at printing enterprises for printing multicolor products using traditional printing methods. According to the results of a quantitative assessment of the surface quality by the indirect Beck method, we can say that paper sample 1 has a smoothness like coated paper (750–1500 s), paper samples 2 and 3 – like calendered paper, so that these paper samples can be recommended for prints with increased quality requirements. Smaller values of roughness Ra and small depressions, expressed by darkening in the topographic AFM images, characterized sufficient homogeneity and density of the structure. It was also revealed that the surface of the paper samples has a high ability to specularly reflect the incident light, since the percentage of surface reflection is similar to that of coated papers. Samples of paper have a whiteness of about 90 % and do not have a tint, since the difference between the maximum and minimum values of the reflection coefficients on a white stack is not more than 10 %. The tested paper samples can be recommended without restrictions for double-sided printing, since the opacity index is more than 92 %.

Abstract:

The coating binder migration and concentration in z-direction of coating layer especially in coating surface influence coated paper optical properties. The results showed that with the increase of coating surface binder migration, the calendaring gloss decreases, the printing gloss and the printing optical density increases. The calendaring gloss and printing gloss, compared to the influence of binder distribution in coating layer,seemed more subject to coating surface binder concentration. Binder in the coating surface concentration and distribution in z-direction almost did not affect the whiteness of coated paper.

Abstract:

The impact of coated paper printability for image quality on the high-fidelity digital printing was studied in this paper. Compared with the traditional printing technology, high-fidelity digital printing technology is more likely to expand the color gamut, maintain the original tone linear and produce vivid image. The performance of coated paper to a large extent determines the image quality. In order to get high-quality printed matters, the mechanism of the coated paper printability influencing on the performance on high-fidelity digital printing is need to be researched in-depth. The printability of coated paper was studied from several aspects in this paper, including the structural properties, roughness, optical properties, absorption etc, the relationships between these properties and printing color, dot reproduction performance were also studied. Based on the previous theoretical and practical studies, the printability evaluation system of coated paper on high-fidelity digital printing was established initially. On digital printing, accurate color management technology also affects the printing quality as the performance of coated paper, so the advanced color management technology was also used in the current study. The results showed that the pore structure and the absorbent of coated paper were the most important factors for affecting the printing quality, and the roughness and optical properties of coated paper also had a certain impact.

Abstract:

Since the monumental work conducted by Whitesides et al. in 2007, research and development of paper-based microfluidics has been widely carried out, with its applications ranging from chemical and biological detection and analysis, to environmental monitoring and food-safety inspection. Paper-based microfluidics possesses several competitive advantages over other substrate materials, such as being simple, inexpensive, power-free for fluid transport, lightweight, biodegradable, biocompatible, good for colorimetric tests, flammable for easy disposal of used paper-based diagnostic devices by incineration, and being chemically modifiable. Myriad methods have been demonstrated to fabricate paper-based microfluidics, such as solid wax printing, cutting, photolithography, microembossing, etc. In this study, fabrication of paper-based microfluidics was demonstrated by spray on the printed paper. Different from the normally used filter papers, printing paper, which is much more accessible and cheaper, was utilized as the substrate material. The toner was intended to serve as the mask and the patterned hydrophobic barrier was formed after spray and heating. The processing parameters such as toner coverage on the printing paper, properties of the hydrophobic spray, surface properties of the paper, and curing temperature and time were systematically investigated. It was found that, after repetitive printing four times, the toner was able to prevent the hydrophobic spray (the mixture of PDMS and ethyl acetate) from wicking through the printing paper. The overall processing time for fabrication of paper-based microfluidic chips was less than 10 min and the technique is potentially scalable. Glucose detection was conducted using the microfluidic paper-based analytical devices (µPADs) as fabricated and a linear relationship was obtained between 1 and 10 mM.

Abstract:

Nowadays, the attention in many industries is shifting towards the problem of waste overproduction and production of the waste in general. This study aimed to find an alternative approach to the production of packaging which will be environmentally friendly and at the same time optimal in terms of the print quality. This was accomplished by using the minimal needed amount of material for the production of packaging and adjusting the parameters of the flexographic printing process to achieve the desired visual impression of the print. The designed motive for the packaging was printed on five different recycled papers, following the guidelines of sustainable design. Printing was performed on each recycled paper with different printing pressures (50N, 150N, and 400N). Smoothness was measured on each paper; and for every printed sample, colorimetric measurements and thickness of the lines in positive and negative were measured. Print contrast for each print was calculated, and microscopy of fine printed elements was performed. All chosen papers except one had average smoothnes of up to 3.2 s (the smoothest paper had the average smootheness value of 54.72 s). Smoothness results influenced the printed line widths. Specifically, when increasing the printing pressure, a significant deformation of the line width has occured on all papers except the smoothest one (deformations of the lines printed in positive were up to 400 μm for rough papers compared to maximum of 60 μm for lines printed on the smoother paper). Similar results were obtained for the lines printed in negative. Furthermore, legibility of the printed typographic elements of 4pt size was significantly influenced by the smoothness of the paper. Elements printed on the smoothest paper have displayed the negligible deformations when changing the printing pressure. For other papers, elements in positive were optimally printed by 50 N pressure, and elements in negative by the pressure of 400 N. The results of this research have enabled the optimization of the flexographic printing process when using each of the five types of recycled papers. Furthermore, the presented qualitative and colorimetric parameters of the prints enabled the assessment of the applicability of used papers as printing substrates for ecologically favorable packaging.

Abstract:

Paper printability is an essential property affecting printing technology and quality. In this research, a predictive model for paper comprehensive printability is presented based on a simple analytic expression. Five properties of two-sided offset paper are tested with smoothness(k1), whiteness(k2), glossiness(k3), ink absorption(k4) and surface strength(k5). Weights for the properties are calculated by principal components regression (PCR) with software SPSS. Then the expression M(k1 , k2 , k3 , k4 , k5) between paper properties and printability synthetic value is obtained. In the same way, weights for the printing quality performances including density(l1), hue error(l2), gray scale(l3) and saturation(l4) are calculated by PCR and the expression N(l1 , l2 , l3 , l4) between printing quality performances and synthetic value is got. Then the fitted curve Y(x) (x is paper printability synthetic value; Y is printing quality synthetic value) is derived and x is replaced by expression M(k1 , k2 , k3 , k4 , k5). As a result the predictive model for two-sided offset paper comprehensive printability can be developed by the paper properties tested. It is shown that the predictive model can provide a practical and quantitative method for evaluating the comprehensive printability of two-sided offset paper fast and can meet the industry analysis requirements with good precision.

Abstract:

Offset paper properties have great influence on the quality of print matter. Eleven offset paper samples were printed by IGT printability tester, then the density and L*a*b values of printed samples were measured. The relationship between paper properties and optical density or color gamut of paper printed was studied. The results show that main density increases with the increased ink quantity before the main density reaches saturation, the saturation density becomes greater with increased ink absorbency. When the smoothness is larger, lower ink quantity is needed for reaching saturation density, and larger color gamut is obtained. This study will provide references for the paper making and printing enterprises.

Abstract:

Fluorescent whitening agent is relatively small dosage in the coating, but it has great influence on the properties of the coating and ink-jet printing qualities. With the increase of fluorescent whitening agent dosage, the PH of the coating rose but the viscosity was hardly to change. The brightness of coated ink-jet printing paper and color density of the printing image firstly presented the trend of increasing then decreasing. What’s more, when the brightness of the coated paper achieved to the maximum, color density and contact angle properties were the largest. Chromatic aberration property of the image reduced from 1.87 to 1.75, when the addition of fluorescent whitening agent rose from 0.1% to 0.5%. While the dosage was rose to 0.9%, chromatic aberration increased to 2.15. The gloss of coated paper decreased with the dosage of fluorescent whitening agent increasing. In sum, fluorescent whitening agent can enhance the brightness of the coated paper as well as the printing properties. The results show that the best brightness and printing qualities of coated ink-jet printing paper are obtained, when the fluorescent whitening agent is 0.5%( relative to pigment).

Abstract:

The properties of art paper and offset paper were measured, including whiteness, smoothness, gloss and absorbability. And these paper samples were printed using machine proofing with the uniform printing processes. Dot percentage and the tri-stimulus values (X, Y and Z) of dot areas and solid areas were tested with the spectrophotometer X-Rite 530 on the print paper samples. At last, dot gain curve and chromatic diagram were drawn after data analyzing and processing, and then the influences of paper properties on printing dot gain and gamut of color were analyzed. The results showed less dot gain value and greater gamut of color occurred because of higher smoothness, gloss, whiteness and lower absorbability to art paper when the printing conditions were definite, so the dot reproduction quality on the surface of art papers was better. But which of the above-mentioned were opposite to offset papers.

The coating binder migration and concentration in z-direction of coating layer especially in coating surface influence the coated paper printing properties. The results indicated that with the increase of coating surface binder migration, the coated paper opacity decreases, and the K&N value decreases. The relationship of K&N value and binder concentration in surface of coating layer was linear, which indicated that compared to binder dosage concentration in coating color, the K&N value and coating surface binder concentration has higher correlation. The more uniform the binder distribution in cross section of coating layer, the greater the IGT.

Abstract:

Purpose This paper aims to summarize the latest developments both in terms of theoretical understanding and experimental techniques related to inkjet fluids. The purpose is to provide practitioners a self-contained review of how the performance of inkjet and inkjet-based three-dimensional (3D) printing is fundamentally influenced by the properties of inkjet fluids. Design/methodology/approach This paper is written for practitioners who may not be familiar with the underlying physics of inkjet printing. The paper thus begins with a brief review of basic concepts in inkjet fluid characterization and the relevant dimensionless groups. Then, how drop impact and contact angle affect the footprint and resolution of inkjet printing is reviewed, especially onto powder and fabrics that are relevant to 3D printing and flexible electronics applications. A future outlook is given at the end of this review paper. Findings The jettability of Newtonian fluids is well-studied and has been generalized using a dimensionless Ohnesorge number. However, the inclusion of various functional materials may modify the ink fluid properties, leading to non-Newtonian behavior, such as shear thinning and elasticity. This paper discusses the current understanding of common inkjet fluids, such as particle suspensions, shear-thinning fluids and viscoelastic fluids. Originality/value A number of excellent review papers on the applications of inkjet and inkjet-based 3D printing already exist. This paper focuses on highlighting the current scientific understanding and possible future directions.

Abstract:

Lateral or cross-machine direction (CD) web movement in printing or converting can cause problems such as misregistration, wrinkles, breaks, and folder issues. The role of paper properties in this problem was studied by measuring lateral web positions on commercial printing presses and on a pilot-scale roll testing facility (RTF). The findings clearly showed that CD profiles of machine direction (MD) tension were a key factor in web stability. Uneven tension profiles cause the web to move towards the low-tension side. Although extremely nonuniform tension profiles are visible as bagginess, more often, tension profiles must be detected by precision devices such as the RTF. Once detected, the profiles may be analyzed to determine the cause of web offset and weaving problems. Causes of tension profiles can originate from nonuniform paper properties. For example, by means of case studies, we show that an uneven moisture profile entering the dryer section can lead to a nonuniform tension profile and lateral web movement. Time-varying changes in basis weight or stiffness may also lead to oscillations in the web’s lateral position. These problems were corrected by identifying the root cause and making appropriate changes. In addition, we developed a mathematical model of lateral stability that explains the underlying mechanisms and can be used to understand and correct causes of lateral web instability

The results showed that smaller dot gain value and greater color gamut occur on the art paper due to its higher smoothness, gloss and lower absorbability when the printing conditions were the same, so the printing dot reproduction quality on the surface of art paper is better. However because offset paper has lower smoothness and gloss, higher absorbability compared with art paper, therefore the dot reproduction quality on offset paper is not as good as art paper.

Abstract:

Creation of new digital technologies let automate the reproduction of text and graphic information, led to the creation and development of the digital printing. Digital printing is a technology for producing prints in the printer based on the original layout, created as corresponding codes with a computer. One of the technologies of digital printing is a computer-to-press and one of the devices in this direction is risograph. The risograph printing quality is worse than offset printing. The text is printing with medium sharpness and images remind photos in old newspapers and require special preparation. But risograph is the most profitable solution for small and medium circulations from 50 up to 1000 sheets. Wide usage of risograph printing in typographies demands increase performance of the equipment with the high print quality of digital images. To improve the quality of risographic printing, the creation of methods is required to form the initial indicators of the original layout (clarity, correct transmission of halftones, contrast). At the same time, the result of obtaining high-quality images obtained by printing on a risograph is affected by surface microgeometry and the physical and mechanical properties of paper. So, the optical density of the ink layer on the print is largely determined by the structure of the sections of paper, in particular, absorbency and porosity. To obtain high-quality images on prints, it is necessary not only to customize the original layout, but also to select paper with such characteristics that would allow you to get the best result when printing on a risograph. Since the risograph occupies an intermediate place in quality between copying equipment and laser printing, a laser print is taken as the standard for print quality. And one of the tasks of the quality of risographic prints is to increase it to the quality of laser printing.

Abstract:

In order to predict and control the ink penetration depth, The base properties of 5 offset paper were firstly measured, namely, tightness、smoothness and K&N ink absorbency, etc. Then the penetration depth when offset magenta ink of the same volume entered into these papers was tested after printing. It was analyzed on the influences of offset paper and print processes on ink penetration depth. Finally, the relationships between the ink penetration depth under pressure and that under no pressure were studied. The results showed that both the tightness and smoothness of offset papers had impact on ink penetration into the paper internal structure, and the total ink penetration depth was about 1/5~1/3 of the thickness of the offset papers. In addition, the ink penetration depth under pressure was obviously lager than that under no pressure.

Abstract:

Nowadays, there is a strong initiative to use recycled or biodegradable materials in all aspects of production including the graphic industry. In this study, paper was used as a material fulfilling the two of mentioned properties. Under laboratory conditions, papers were made of 70% pulp from recycled wood fibres with an addition of 30% straw pulp (wheat, barley or triticale). Considering the importance of the possibility of printing such media based on their end use, the influence of fibre type on vapour barrier properties was studied and overall migration to hydrophilic and fatty food simulants was measured. Analyses were performed on digital, flexographic, and offset prints obtained by printing laboratory papers with UV-curable black ink. It was found that prints produced using the offset technique, in which the ink remains on the surface of the paper, had lower overall levels of migration compared to other printing techniques. The paper produced appears to have the potential to be used as a secondary food packaging material.

Abstract:

The spread of invasive alien plant species (IAPS) is a leading reason for worldwide environmental change due to their effects on biodiversity and humans. Some valued goods from IAPS have been produced, e.g. paper that consists of cellulose fibres from Japanese knotweed. Therefore, the aim of this study was to establish the usability of this paper grade as a printing substrate, since it does not have ideal optical properties as it is expected from commercial office paper. Because it is widely used, inkjet printing technology was employed. Print permanence is essential, especially when printing documents. However, typographic characteristics must be considered to make a text more legible. Two widely used typefaces (Arial and Times) were tested in three commonly used type sizes (8 pt, 10 pt, and 12 pt). The results showed that the paper made from Japanese knotweed could have valuable properties and suitable legibility, especially when using typefaces with a moderate counter size, high x-height, and minimal differences in the letter stroke width to obtain an appropriate typographic tonal density with an adequate type size. Even after exposure to light, the texts printed in a proper type size and stroke width remained visible.

Abstract:

In the LTCC process, metal layers are usually deposited by screen printing conductor material on unfired tape substrate. Despite being widely used, this method has certain disadvantages, such as limited resolution of the printing process. An alternative method of producing conductor patterns is to deposit a uniform conductor paste layer on the substrate and the use a Nd:YAG laser to selectively ablate the conductor material, producing a desired pattern. This method allows achieving a higher patterning precision and also eliminates photochemical process of screen preparation, which makes it an attractive choice for rapid prototyping applications. Laser ablation step can be performed either post-firing (for a top conductor layer) or pre-firing (which allows for patterning buried layers). The aim of this paper is to investigate surface properties of LTCC ceramics processed by laser etching. Precision optical imaging and SEM are used to determine etched surface properties, and EDS analysis is used to determine its chemical composition. Effectiveness of conductor removal is investigated by comparing surface resistivity and metal content in raw and etched samples.

Abstract:

Исследована возможность повысить эффективность очистки макулатуры марки МС-7Б от тонера, нанесённого на лазерном принтере путём сухого двухстадийного диспергирования перед флотацией. Использовалась макулатура с разным уровнем запечатанности с одной стороны бумаги: 2,5%, 3,9, 8,2, 60%. Степень запечатанности офисной макулатуры определяли с помощью программы «lpSquare v5.0 for Windows» как отношение площади запечатанной области к общей площади листа (в %). Уровень очистки макулатуры от вкраплений тонера определяли с помощью графической программы, которая позволяла установить площадь области чёрного цвета. Установлено, что разработанная технология подготовки макулатурной массы, включающая двухстадийное сухое диспергирование и последующую флотацию, эффективно удаляет вкрапления тонера в образцах бумаги. Вкрапления тонера в образцах бумаги, полученной из макулатуры облагороженной флотацией с предварительным двухстадийным сухим диспергированием, практически отсутствуют, в отличие от образцов бумаги из макулатуры, облагороженной стандартной флотацией. Оценка механических свойств образцов бумаги осуществлялась по изменению показателей – сопротивления продавливанию и сопротивления разрыву. Показано, что подготовка макулатурной массы методом флотации с предварительным сухим дисперированием способствует небольшому повышению механических показателей образцов бумаги. Механические показатели образцов бумаги практически не зависят от уровня запечатанности макулатуры. The possibility of improving the efficiency of deinking «МС-7Б» grade recovered paper from toner applied on a laser printer by dry two-stage dispersion before flotation was investigated. Recovered paper was used with a different level of toner print on one side of the paper: 2.5%; 3,9%; 8,2%; 60%. The degree of toner prints of office recovered paper was determined by the program «lpSquare v5.0 for Windows» as the ratio of the area of the printed area to the total area of the sheet in %. The level of cleaning recovered paper from toner embossments was determined using a graphic program that made it possible to establish the area of the black area. It has been found that the developed recovered paper stock preparation technology involving two-stage dry dispersion and subsequent flotation effectively removes toner print area in paper samples. Toner print area in samples of paper obtained from floated recovered paper with preliminary two-stage dry dispersion are practically absent, unlike samples of paper from recovered paper ennobled with standard flotation. Assessment of mechanical properties of paper samples was carried out by changing the values of bursting and tinsel strength. It is shown that preparation of recovered paper stock by method of flotation with preliminary dry dispersion contributes to small increase of mechanical indices of paper samples. The mechanical properties of paper samples practically does not depend on the level of toner print area of recovered paper.

Abstract:

The distributed and customized 3D printing can be realized by 3D printing services in a cloud manufacturing environment. As a growing number of 3D printers are becoming accessible on various 3D printing service platforms, there raises the concern over the validation of virtual product designs and their manufacturing procedures for novices as well as users with 3D printing experience before physical products are produced through the cloud platform. This paper presents a 3D model to help users validate their designs and requirements not only in the traditional digital 3D model properties like shape and size, but also in physical material properties and manufacturing properties when producing physical products like surface roughness, print accuracy and part cost. These properties are closely related to the process of 3D printing and materials. In order to establish the 3D model, the paper analyzes the model of the 3D printing process selection in the cloud platform. Triangular intuitionistic fuzzy numbers are applied to generate a set of 3D printers with the same process and material. Based on the 3D printing process selection model, users can establish the 3D model and validate their designs and requirements on physical material properties and manufacturing properties before printing physical products.

Abstract:

Purpose This paper aims to summarize the up-to-date research performed on combinations of various biofibers and resin systems used in different three-dimensional (3D) printing technologies, including powder-based, material extrusion, solid-sheet and liquid-based systems. Detailed information about each process, including materials used and process design, are described, with the resultant products’ mechanical properties compared with those of 3D-printed parts produced from pure resin or different material combinations. In most processes introduced in this paper, biofibers are beneficial in improving the mechanical properties of 3D-printed parts and the biodegradability of the parts made using these green materials is also greatly improved. However, research on 3D printing of biofiber-reinforced composites is still far from complete, and there are still many further studies and research areas that could be explored in the future. Design/methodology/approach The paper starts with an overview of the current scenario of the composite manufacturing industry and then the problems of advanced composite materials are pointed out, followed by an introduction of biocomposites. The main body of the paper covers literature reviews of recently emerged 3D printing technologies that were applied to biofiber-reinforced composite materials. This part is classified into subsections based on the form of the starting materials used in the 3D printing process. A comprehensive conclusion is drawn at the end of the paper summarizing the findings by the authors. Findings Most of the biofiber-reinforced 3D-printed products exhibited improved mechanical properties than products printed using pure resin, indicating that biofibers are good replacements for synthetic ones. However, synthetic fibers are far from being completely replaced by biofibers due to several of their disadvantages including higher moisture absorbance, lower thermal stability and mechanical properties. Many studies are being performed to solve these problems, yet there are still some 3D printing technologies in which research concerning biofiber-reinforced composite parts is quite limited. This paper unveils potential research directions that would further develop 3D printing in a sustainable manner. Originality/value This paper is a summary of attempts to use biofibers as reinforcements together with different resin systems as the starting material for 3D printing processes, and most of the currently available 3D printing techniques are included herein. All of these attempts are solutions to some principal problems with current 3D printing processes such as the limit in the variety of materials and the poor mechanical performance of 3D printed parts. Various types of biofibers are involved in these studies. This paper unveils potential research directions that would further widen the use of biofibers in 3D printing in a sustainable manner.

Abstract:

Abstract During xerographic printing processes, the electric charge properties of the paper surface are essential to obtain effective toner transfer and high image quality. Surface and volume resistance are indispensable to the accumulation of the surface charge and different resistance values generate different electrical fields with optical drum, and have a significant effect on toner transfer efficiency. In this paper, surface sizing was investigated to improve the surface properties for better toner transfer and image quality. Styrene acrylate emulsion (SAE) latex was successfully synthesized and fully characterized with a Fourier transform infrared (FT-IR) spectrometer, a laser particle analyzer and a scanning electron microscope (SEM). The results showed that under the conditions of emulsifier dosage at 3 wt%, initiator concentration at 0.5 wt% and the reaction temperature at 80°C, the monomer conversion can reach 80%. The effects of various factors including initiator dosage, emulsifier dosage and monomer ratio on the sizing performance were studied. The effects of different ratios of SAE to starch on surface and volume resistance of paper were also systematically investigated. The differences in electric properties of various paper samples were quantified and their influence on paper-toner adhesion and print quality was clarified. Relationships between electrical properties of paper and paper-toner adhesion force, and thus print quality were established. Strategies to improve printing performance through effective control of paper electrical properties were also developed. It is concluded that the best printing quality and toner adhesion were achieved when the ratio of SAE to starch is between 1:10 and 2:10.

Abstract:

Virgin newsprint paper from thermo-mechanical pulp was subjected to a laboratory recycling scheme, which involved mimeograph-printing, re-pulping, de-inking, washing, refining, and handsheetforming, without adding other fibre in between cycles. Fibre dimension, pulp freeness and paper properties were determined after each cycle until the fifth, at which about 20% of the original material remained. The remaining fibre was then mixed with virgin pulp, the original newsprint and unsorted mixed office waste to determine the proportion necessary for acceptable properties. The results indicated remarkable modification in distribution of fibre properties, a decreasing amount of long fibre with corresponding increase of short fibre in the course of recycling and loss of fibre. Refining generally improved the strength properties of paper from recycled fibre. About 20 % to 30 % of either thermo-mechanical pulp or unsorted mixed office waste was found sufficient for blending with recycled fibre to obtain acceptable strength properties.

Abstract Functionally graded materials (FGMs) describe composite materials with a gradual change in properties along one or several axes. A major advantage with this approach is the avoidance of discontinuities between different layers of material. 3D Printing offers the possibility to control the material composition and spatial placement along the printing process to create structures with graded properties. However, there are very few examples of the application of this approach to 3D concrete printing (3DCP). This paper presents a review of the current approaches of and methods to grade the material properties of a 3DCP structure, as well as a review of similar methods used in other 3D printing processes. Finally, the potential applicability of these principles into concrete are presented and discussed.

The physical structure and chemical properties of coating layer have an important influence on transferring and setting of the printing ink. The typical objective of coating is to improve the appearance and printing properties of paper. In this study, the effect of drying condition on coating layer structure, surface properties, and print quality was investigated. The relationship between surface topography and drying condition was explored using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The conclusions were drawn that high and low drying temperature were not good to the paper properties, which resulted in high roughness, low paper gloss, high ink absorption, low print gloss and paper surface efficiency. The findings indicated that the coating drying temperature affected the pore size, depth and distribution of the coated paper surface. Moderate temperature was benefit to pigment particles and binder arranging orderly, which made the coating surface had high smoothness, gloss, paper surface efficiency, and modest ink absorption.

Abstract:

The paper properties such as roughness, gloss, surface wettability and other factors have great influence on the dot reproduction attributes of presswork, and different paper factor has different effect weight on the dot reproduction. The main purpose of this paper is to provide a new method to analyze the influence of paper properties on the dot reproduction. The method is to apply the grey relational analysis to analyze the influence law and the effect weight of paper factors on the dot reproduction during inkjet printing, which could provide theoretical guidance for improving the printability of paper. The grey relational analysis is a multi-factor statistical analysis method, which is based on the sample data and the grey incidence of various factors and is used to describe the strength, size and the order of the relationship between the factors. In this experiment, five types of inkjet printing paper were used to test their printing performance, and then the dot gain data were dealt with by the grey relational analysis method. Results showed that paper properties had a great influence on ink setting. Ink drop diffused and deformed less and dot gain was small when paper had smooth surface. According to the correlation coefficient degree of paper properties which influence on the dot gain of inkjet printing, the sequence was whiteness, roughness, surface wettability and gloss. Whiteness and roughness could significantly influence dot gain, followed by surface wettability, and gloss with minimal impact. Experiment indicated that the grey relational analysis was a simple and effective tool to analyze the influence of paper properties on the dot reproduction of presswork.

Abstract:

The history of printing technology in Korea is studied by investigating existing ancient documents and records and comparing accumulated data and knowledge. Cultural property research requires non-destructive testing and observation with the naked eye or aided by a microscope. Researchers’ experience and knowledge are required even though they cannot guarantee the outcome. For ancient documents and records that are presumed to consist of woodblock printing, wood type printing, metal type printing, or their combinations, each researcher draws various opinions and conclusions. This often causes confusion and divides the opinions of ordinary citizens and field specialists. Among them, the criteria for judging ancient documents or books printed using woodblock and metal movable material are ambiguous. Academic research on the development history of printing technology in ancient Korea has been stagnant, and conflicts among researchers have also erupted. Involvement of national investigative agencies not specialized in cultural properties has exacerbated the situation. In this study, we investigated printing characteristics that are likely to serve as more objective judgment criteria by quantitatively analyzing the experiments of retrieving several sheets of Korean paper (Hanji) using a replicated Hunminjeongeum (訓民正音) woodblock and quantitatively analyzing the images of the printed papers. In addition, the validity and questions for the typical phenomena presented as a method for distinguishing between woodblock and metal print are reviewed. We investigated the possibility of developing new objective judgement criteria through quantitative analysis using image analysis and investigating the printing characteristics of Korean paper through a reproduction experiment of woodblock printing.

Abstract:

In the offset process, ink penetration performance has extremely important influence on the quality of printed products. Ink penetration behavior and ink transfer volume on the offset paper surface were researched with the aid of IGT printability tester (AIC2-5) in the conditions of temperature 20±3°C and humidity of 60 ± 5%. Effect of different printing pressure and printing speed on the ink penetration depth was discussed, and at the same time, the depth was measured by GX71 Inverted Metallurgical Microscope. The results showed that, with the increasing of printing pressure, the changes of ink penetration depth and the ink transfer volume on offset paper surface were increased firstly and then decreased. When printing pressure was 400N, the ink penetration depth reached the maximum 71.67μm and the ink transfer volume reached the maximum too. With the enhancing of printing speed, ink penetration depth and ink transfer volume would be decreased gradually. The study also found that ink penetration behavior had certain influence on the ink color forming properties. For the offset paper used in this experiment, when ink penetration depth was 60.0μm~63.0μm, the print had high ink color intensity and color efficiency. When the ink penetration depth was too deep, ink color intensity and color efficiency was significantly reduced, while the color hue error would be increased, the print ink color turned shallow.

Abstract:

Color 3D printing allows for 3D-printed parts to represent 3D objects more realistically, but its surface color quality evaluation lacks comprehensive objective verification considering printing materials. In this study, a unique test model was designed and printed using eco-friendly and vivid paper-based full-color 3D printing as an example. By measuring the chromaticity, roughness, glossiness, and whiteness properties of 3D-printed surfaces and by acquiring images of their main viewing surfaces, this work skillfully explores the correlation between the color representation of a paper-based 3D-printed coloring layer and its attached underneath blank layer. Quantitative analysis was performed using ΔE*ab, feature similarity index measure of color image (FSIMc), and improved color-image-difference (iCID) values. The experimental results show that a color difference on color-printed surfaces exhibits a high linear correlation trend with its FSIMc metric and iCID metric. The qualitative analysis of microscopic imaging and the quantitative analysis of the above three surface properties corroborate the prediction of the linear correlation between color difference and image-based metrics. This study can provide inspiration for the development of computational coloring materials for additive manufacturing.
