Abstract. Gravure printing has the characteristics including thick ink layer, bright and homochromatic color, rich and sharp tone, and strong stereoscopic impression. In the packaging-printing field, gravure printing gets more and more attentions. But in the region of gravure printing process, the study on gravure printing ink transfer is not as deep as offset print. Most researches just stay in the level of qualitative analysis, but the quantitative analysis researches are still insufficient. The factors which impact gravure printing ink transfer are not only the volume of engraving ink cell, but also printing process. In this paper, gravure printing ink transfer is analyzed quantitatively from the point of views of gravure printing pressure, printing speed, scraping blade pressure and ink viscosity. The following research has been done in this paper. Firstly, electronic engraving machine is used to engrave eight different area ink cells by 45° ink cell angle and 70lpc screen line number on the same gravure roller. Secondly, gravure proofing machine is used to make proofs in different process conditions. Thirdly, density meter is used to determine density of cell ink, and balance is used to determine the weight of ink which moves from the plate onto the paper. Finally, to analyze the influence of different printing processes on gravure printing ink transfer. The research results show that gravure printing ink transfer is influenced certainly by different printing processes. Printing process has a certain influence on the gravure printing ink transfer, and the influence degree of different dot area rate of cell is different. The doctor blade pressure and ink viscosity influence greatly gravure printing ink transfer.

Abstract:

Ink is transferred and sets onto the paper surface in the printing process, which affect printing quality and usage of ink. The objective of this experiment was to investigate the influence of ink type on ink absorption and characterize the penetration depth through quantitative analysis by Laser Scanning Confocal Microscope (LSCM). Fluorescent ink was used to observe and characterize ink penetration by LSCM. Three-dimensional images of ink pigment penetration were obtained by reconstructing all XY plane images. It could be concluded Common offset printing ink compared with UV offset printing resulted in deeper ink penetration ,uneven ink distribution and lower print density. Because the composition and drying method of UV offset printing ink and common offset printing ink were significant different, penetration depth and distribution uniformity of these two types of offset printing ink in coated paper were distinct.

Abstract:

Abstract The rheological properties of silver inks are analyzed, and the printing results are presented based on the inks and roll-to-roll (R2R) printing speed. The shear viscosity, shear modulus, and extensional viscosity of the inks are measured using rotational and extensional rheometers. The inks exhibit the shear thinning power law fluids because the concentration of dispersed nanoparticles in the solvent is sufficiently low, which minimizes elasticity. After the inks are printed on a flexible substrate through gravure printing, the optical images, surface profiles, and electric resistances of the printed pattern are obtained. The width and height of the printed pattern change depending on the ink viscosity, whereas the printing speed does not significantly affect the widening. The drag-out tail is reduced at high ink viscosities and fast printing speeds, thereby improving the printed pattern quality in the R2R process. Based on the results obtained, we suggest ink and printing conditions that result in high printing quality for complicated printings, such as overlay printing registration accuracy, which imposes pattern widening and drag-out tails in printed patterns.

Abstract:

The experiment studied effects of paper on the height and glossiness of UV ink-jet 3D printing. The results showed that there all existed penetrations between the 1st ink layer and three kinds of paper, the bigger the roughness and bulk of paper were, the larger the penetration was, and penetration between the 1st ink and paper was obviously larger than that between two ink layers. Penetration between two ink layers was stable, almost not affected by paper. The bigger the roughness and bulk of paper were, the smaller the glossiness of ink layer was. There appeared directional ink strips on ink layer on three kinds of paper, beginning from the 3rd ink layer, there also appeared ink pits on ink layer on paper whose roughness and bulk were the biggest, which showed printer precision was also an important factor for the glossiness, apart from paper. Thus, the tight and smooth paper should be selected in UV ink-jet 3D printing. Before printing, pretreatment should be done to exclude the influence of the 1st ink layer and the ink strips.

Abstract:

The roll-to-roll gravure printing ink transfer process plays an important role in enhancing printing quality and saving on costs. The static analysis and fluid–solid interaction method are used for the first time to conduct a systematic study on the coupling between the fluid flow state and the solid deformation in the whole process of roll-to-roll gravure printing. The static compression stage, the initial moment of ink transfer, and the process of ink passing through the gap between two rollers and the separation of the ink layer with the rotation of two rollers are considered. The effect of ink layer thickness on the ink transfer process is studied. At a printing pressure of 0.2 MPa and a printing velocity of 200 rpm, the ink thickness has a great influence on the ink flow state, which leads to backflow; the phenomenon causes irregularities in the effective ink transfer ratio. The critical ink layer thickness is 70 µm under the above gravure printing conditions. This should not be exceeded to ensure the stability of ink transfer. Under the above printing conditions, when the ink layer thickness is in the range of 30–50 µm, there is no ink backflow phenomenon and the width of the ink flow channel is relatively large, and the effective ink ratio is almost stable at 50%. This study is helpful for controlling the ink quantity in the gravure printing, providing strong theoretical support for the improvement of the gravure printing process, and promoting the application of the water-based ink.

Abstract:

Flexographic printing is widely used in the packaging field, but there are still some problems in the printing of flexographic ink on non-absorbent substrates, such as low precision and unstable quality. In this paper, the printing process of flexographic ink is simulated. The interaction of fluid flow, temperature change, and solid deformation in flexographic printing is studied systematically by using the method of fluid–solid thermal coupling for the first time. The process of ink channel formation under static extrusion and fluid–solid thermal coupling was analyzed. The influences of printing pressure, printing speed, ink layer thickness, and ink viscosity on the ink channel were explored. The results show that the printing speed increases and the temperature in the stamping area increases. The printing speed is nonlinear related to the ink flow channel, the influence on the channel is slow at a low speed, the channel increases sharply at a medium and high speed, and tends to be stable at a high speed. When the printing speed is 200 m/min, the ink temperature in the stamping area is 1.5 °C higher than that at the entrance. With an increase in printing pressure, the ink flow channel width showed a trend of decreasing first and then stabilizing, and the pressure was about 0.4 MPa, showing a small fluctuation; the greater the pressure, the higher the temperature of the ink, which will change the performance of the ink and plate, causing adverse effects on the printing belt. The channel width showed obvious nonlinear characteristics with an increase and decrease in ink thickness. When the ink thickness is 30 μm, the deformation of the plate reaches the maximum, and the width of the ink circulation channel is correspondingly the widest. The change in ink viscosity has little influence on the stability of the ink’s internal flow rate and temperature field. The research results provide theoretical support for the transfer of ink printing from gravure to flexo printing.

Abstract:

Purpose The purpose of this study is to explain the effects of screen printing parameters on the quantity of ink deposited and the print quality in the context of printing of functional inks. Both these aspects of printing are crucial in the case of conventional and functional printing. This is because, in the case of conventional printing, the quantity of ink deposit affects the color strength while in the case of functional printing, it directly affects the resulting functionality of the ink layer. Design/methodology/approach In this work, an automatic lab-scale screen printer was used to print functional inks on a paper board substrate. The printing parameters, i.e. printing pressure and squeegee angle were altered and the resulting effects on the quantity of ink that was deposited were recorded. The quantity of ink deposit was related to its surface resistivity. In addition, the quality of the print was also assessed by examining the design registration quality. Findings The authors found that altering the squeegee angle has a significant effect on the properties of the resulting ink deposit. More importantly, the authors found that the deflection in the rubber blade squeegee was greatly dependent on the initial angle of the squeegee at the start of the printing stroke. For each set value of the squeegee angle that was considered, the actual angle during printing was recorded and used in the analysis. A printing pressure of three bars and squeegee angle of 20° resulted in the maximum weight of ink deposit with a correspondingly lowest surface resistivity. Practical implications This study is envisaged to have considerable practical implications in the rapidly growing field of functional printing of flexible substrates including, but not limited to, textiles. This is because, the study provides an insight into the effects of printing parameters on the characteristics of a functional ink deposit. Originality/value Screen printing of flexible substrates is a well-developed and arguably the most widely used printing technique, particularly for textiles. Numerous studies report on the analysis of various aspects of screen printing. However, to the best of the knowledge, the effects of printing parameters on the characteristics of functional inks, such as electrically conductive inks, have not been studied in this manner.

Abstract:

What happens in the paper surface about ink absorption is of great important for appearance of final printing. The aim of this experiment was to investigate the influence of printing pressure and printing speed on ink layer thickness transferred onto coated paper through quantitative analysis by laser scanning confocal microscope (LSCM). Meanwhile, the influence of printing pressure and printing speed on print density and print gloss were obtained. The results implied that higher printing pressure resulted in higher ink layer thickness, print density and print gloss when printing pressure is less than 700N, but higher printing speed resulted in lower ink layer thickness, print density and print gloss when printing pressure is constant. It could be concluded that the coated paper with high printing speed compared with low printing speed resulted in lower ink absorption, lower print density, lower print gloss and worse printability on the condition of same printing pressure.

Abstract:

Inkjet printing of two-dimensional (2D) material has been a center of interest for wearable electronics and has become a promising platform for next-generation technologies. Despite the enormous progress made in printed 2D materials, there are still challenges in finding the optimal printing conditions involving the ink formulation and printing parameters. Adequate ink formulation and printing parameters for target 2D materials rely on empirical studies and repeated trials. Therefore, it is essential to compile promising strategies for ink formulation and printing parameters. In this context, this review discusses the optimal ink formulations to prepare stable ink and steady ink jetting and then explores the critical printing parameters for fabricating printed 2D materials of a high quality. The summary and future prospects for inkjet-printed 2D materials are also addressed.

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:

To survey the influence of ink fineness on the performance of the water-based cork paper bobbin gravure ink and improve the printing quality of ink, the water-based cork paper bobbin gravure inks with different pigment fineness were prepared and the viscosity of ink, glossiness of the printing proof, the abrasion resistance of ink film and other property parameters were tested. The research shows that the ink fineness has a great influence on the water-based cork paper bobbin gravure ink. If the ink fineness is bad, the ink would have a low viscosity. If the ink fineness is good, the glossiness of the printing proof and the abrasion resistance of ink film would be high.

Abstract:

Ink transfer onto the printed surface is provided by parameters as follows: dampening solution in ink emulsification level, dampening solution parameters as long as its ingredients and their exact dosing, dampening solution transfer features between fountain rollers, blanket and printing plate and printed material surface characteristics, thickness and volume of ink on the printing plate, level of ink setting on the imprint. Deviations in transfer from the optimal parameters cause the negative consequences. On the other hand there are hardly any new approaches in explanations of mutual influence of the technological environment parameters in the printing contact which results in lowering the printing process effectiveness while printing with minimal layers of ink-water emulsion. In this article the mutual influence correlations of the printing contact technological environment characteristics are revealed, allowing operating the minimal layers of ink-water emulsion on high-productive machines while normalizing the color reproduction and imprints’ quality.

Abstract:

In order to acquire a suitable ink for ink-jet printing technology, a graphene oxide ink was explored based on the GO aqueous dispersion. The GO dispersion was characterized by field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). The average particle diameter and zeta potential of the GO dispersion was determined by zeta potential & particle size analyzer. The GO ink is composed of 1,2-propanediol, diethylene glycol monobutyl ether, glycerol, polyvinyl pyrrolidone (PVP) and GO dispersion. The surface tension and viscosity of the GO ink was tested by surface tension meter and rheometer. The GO ink was inkjet printed on polyethylene terephthalate (PET) substrate. The optimal inkjet printing parameters were obtained and the printing quality was characterized by confocal laser scanning microscopy. The results show that the GO ink is suitable for inkjet printing technology and the morphology of the GO film with one printing pass has good uniformity.

Abstract:

Alkyd-based printing ink vehicles were successfully prepared from waste frying oil. Three alkyd resins were synthesized using different ratios of phthalic anhydride. Properties of the 3 prepared resins were measured and compared with virgin oil alkyd resin and commercial alkyd resin. Viscosities of the obtained ink vehicles ranged from 8.6 to 34.9 poises. The vehicles were also completely compatible with carbon black for formulating black printing inks. Preliminary properties of the 3 formulated inks were evaluated and compared with black printing ink prepared from virgin oil alkyd and commercial alkyd. The formulated inks had satisfactory viscosity and tackiness as properties suitable for a variety of printing applications. The 3 synthesized inks had rub resistance values ranging from 4.61 to 5.75 %, slightly higher than the rub resistance of virgin oil alkyd ink and commercial alkyd ink. Particle fineness and water tolerance properties of the 3 formulated inks were comparable with virgin oil alkyd ink and commercial alkyd ink. Results suggested that waste frying oil has potential application as a raw material in the printing ink industry.

Printing ink is one of the chemical industry that can be considered as a high risk industry due to it is a manufacture industry that involved all kinds of chemical materials. Thus, reliability data is important for the environmental safety in chemical industries. This study aims to compare the hazardous substances in raw materials for various printing ink production and propose the control measures in the ink production process. Three types of printing ink raw material i.e sheet-fed ink, cold-set ink and heat-set ink were considered in this study. This study was conducted by using a quantitative approaches. Data were collected through Material Safety Data Sheet (MSDS). Hazardous substances were identified from the Chemical Abstract Service (CAS) registry number of the raw materials. The result of the study shown that there are eight hazardous chemical substances in sheet-fed ink, cold-set ink and heat-set ink. The hazardous raw materials identified are mainly from the category of pigment, solvents and additives. From the study of the three types of ink printing, sheet-fed inks contain harmful chemicals that are the lowest of 33.27%, followed by thermal ink-set of 41.73% and cold-set inks of 61.86%. The results also shown that solvents are identified to contribute highest percentage as hazardous chemical substances in the printing ink, followed by additives and pigment. The results of the research shown that the production workers in the printing ink production process are at highly exposed to the hazards. The hierarchy of hazard control based on Department Occupational Safety and Health (DOSH) are proposed to control the hazardous chemical substances. The recommended control measures of possible hazards and risks based on the work activities are elimination, engineering control, administration control and personal protective equipment. This research is very important as it will enhance the precautions and safety knowledge of the employer and employee in handling the chemical substances in the printing ink production process.

Abstract:

Digital inkjet printing has been widely used in textile industry. The quality of dye solutions and ink-jet droplets limits the ink-jet printing performance, which is very important for obtaining high-quality ink-jet printing images on fabrics. In this paper, we introduced diethylene glycol (DEG) into the dye solutions of Reactive Blue 49 and Reactive Orange 13, respectively, and investigated the interaction between dye chromophores and DEG molecules. Results indicated that the dye chromophores were featured in the aggregation. Adding DEG into the dye solution could effectively disaggregate clusters of reactive dyes, and eliminate satellite ink droplets, thus improving the resolution of the ink-jet printing image on fabrics. Under the same DEG concentration, the disaggregation effect was more obvious in Orange 13 than in Reactive Blue 49. Higher DEG concentration was required in Reactive Orange 13 solution for creating complete and stable ink drops. The surface tension and viscosity of the dye solutions were measured, and printing performance on cotton fabrics was evaluated. The interaction mechanism between dye chromophores and DEG molecules was also investigated. Results from this work are useful for high-quality ink-jet printing images on fabrics.

Abstract:

Forgery cases involving printed documents have recently increased due to advanced printing technologies. As a result, various analytical instruments are currently applied in forensic document examination to analyse printing ink. Analyses of printing ink are primarily focused on the ink’s chemical components, namely colourants, vehicles, and additives. Previous studies on ink analysis show an increasing trend in the use of spectroscopy methods including the application of Laser-Induced Breakdown Spectroscopy (LIBS). This instrument is favoured by document examiners in analysing printing ink due to its versatility, simple preparation, multi-elemental detection, minimal destruction, and precise readings. The examination of printing ink using LIBS is reviewed in this publication in addition to findings from previous research. The strengths and drawbacks of this technique, as well as contemporary approaches, are also explored in this article.

Abstract:

The utilization rate of ink liquid in the chamber is critical for the thermal bubble inkjet head. The difficult problem faced by the thermal bubble inkjet printing is how to maximize the use of ink in the chamber and increase the printing frequency. In this paper, by adding a flow restrictor and two narrow channels into the chamber, the H-shape flow-limiting structure is formed. At 1.8 μs, the speed of bubble expansion reaches the maximum, and after passing through the narrow channel, the maximum reverse flow rate of ink decreased by 25%. When the vapor bubble disappeared, the ink fills the nozzle slowly. At 20 μs, after passing through the narrow channel, the maximum flow rate of the ink increases by 39%. The inkjet printing frequency is 40 kHz, and the volume of the ink droplet is about 13.1 pL. The structure improves the frequency of thermal bubble inkjet printing and can maximize the use of liquid in the chamber, providing a reference for cell printing, 3D printing, bioprinting, and other fields.

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.
