The era of environmental protection and personalization has become increasingly prominent, and people not only focus on the beauty of the design, but also pay more attention to the quality of the clothing. For inkjet printing, the viscosity and surface tension of ink are major factors that affect the quality of ink-jet printing. In order to obtain a better print quality, the samples of five different viscosity and surface tension of ink were prepared respectively by changing the content of the resin and the surface active agent. Using these samples to print on the fabric by Epson printer, and to discuss the influence of the ink in different viscosity and surface tension on the ink-jet printing quality, such as apparent color depth (K / S), color parameters (L, C), permeability, clarity. The results showed that: with the increase of the ink viscosity, the apparent depth of color yield increased gradually and became darker in color. L value decreased gradually and had a increasing trend, and tends to be stable. C value increased and vividness of the color was improved. And it also had a certain impact on the infiltration resistance and clarity. Surface tension also had a significant impact on the depth of the apparent color, vividness of the color and directly affected the ink permeability and clarity.

In the process of the ink drops forming and spreading out, the viscosity and surface tension of the ink play an important role, and then the drops’ injection and printing quality will be influenced by this process. Besides, drops control technology is the key of ink-jet printing technology, and the drops’ injection state will also influence the printing quality. In order to research the influencing factors to printing quality, many samples with different performances are prepared and their drop states include speed, tail length and volume are measured with drop observatory. And then, the specimen pages include lines of different width are printed, order to assessment the printing quality comprehensively, their line width, raggedness, blurriness, density and contrast are measured. The result show that the inks with different performance show different speed, tail length and volume, and their corresponding printing qualities are different too, and there exists linear relationship between printing quality and the drops’ viscosity, surface tension and speed.

Sizing Agents

Compared with conventional surface sizing agents, polymers surface size agents are good film and printing quality. In this work, different types of SMA (Styrene Maleic Anhydride) from the United States Hercules and Sartomer companies were investigated. Firstly, each of SMA sizing agents was studied respectively for choosing the optimized SMA depending on the improvement of physical and ink-jet printing properties, and then the effects of different formulation surface size agents containing the optimum SMA and cationic starch on paper and ink-jet printing properties were also studied in order to analyzing the synergism effects of the two surface size agents. The results show that S520 was better than several other SMA surface sizing agents in the improvement of physical properties and ink-jet printing performance of paper. S520 could produce good film property which could reduce the paper permeability, improve smoothness have less loss whiteness and opacity. It could also enhance the color density, expand the scope of the dark tone and improve dots clarity degree of printed paper.

Ink-jet printing technology is the mainstream of digital printing, and piezoelectric ink-jet printing is the main ink-jet printing at present, besides, drop’s injection and controlling technology is the key to the development of ink-jet printing technology. The surface tension plays an important role in the drop’s generation process, it will restrict the length and the state of the drop, further influence ink-jet printing quality. Six edible ink samples with different surface tension are prepared in order to research the influence of the surface tension to the piezoelectric inkjet Printing drop state, then the drop state is observed and its speed and volume are measured through drops observatory. The result shows that the speed of drop is higher if the ink’s surface tension is lower, but the drop is easier to gather into spherical drop and it also has smaller tail length and bigger volume.

with the rapid development of digital printing, the method and standard of quality detection for digital printing become focus of research. The main work and innovations in this paper include: ①Computer image analysis method was applied to ink-jet printing quality detection for the first time; ②Compared with traditional printing quality test, ink dot, line, color patch and MTF (Modulation Transfer Function) were selected as measurement and control elements. And the test proofs for detecting printing quality were designed; ③The detection algorithm and the overall detection process were put forward in this paper. The result of the experiment demonstrates: the detection method based on capturing measurement and control elements by CCD can accurately accomplish the objective quality evaluation for ink-jet printing. Detection method of print was improved to extend the scope of detection by this research, which could be generalized as a standard method for the detection of ink-jet printing quality.

This paper investigates the possibility of reproducing Braille by UV ink-jet printing on self-adhesive labels, previously printed by flexo printing technol- ogy. The aim was to determine whether it is possible to reproduce Braille, the degree of quality of created Braille dots (cells), the legibility of Braille text, and how many layers of varnish are necessary for quality reproduc- tion. The Braille letter was applied to the previously printed label (design) using 8, 10, 12, 14 and 16 layers of varnish. It has been found that it is possible to reproduce a quality and legible Braille. With the increase in the number of layers, the assessment of legibility and quality of reproduction by the respondents also increased. Samples reproduced with 12 layers of varnish received a very good grade of legibility and good grade for quality of Braille. Samples reproduced with 8 and 10 layers received bad grades for legibility, and even worse for quality, while samples with a higher number of layers of varnish, 14 and 16, received even better grades. The threshold for quality reproduction would therefore be the use of 12 layers of varnish, where a good ratio of workmanship and economy is obtained.

With many years of research, color ink-jet printing technology has reached the requirements of color ink-jet printing. The significance of this experiment is to find a suitable method to improve the quality of color ink-jet printing paper. In this work, the dispersion effect and types of sodium polyacrylate (PAAS) on nano-SiO2 solution are discussed, and the most suitable PAAS dosage is selected. When the dosage of PAAS is 8%, the dispersibility of nano-SiO2 solution is much better, with an average color density of 1.60, a gloss of 59% and an ink absorption value of 10.2 cm. Adhesives also have a great influence on color ink-jet printing paper. When the amount of PVA is 30% of nano-SiO2, the average color density is 1.62. Glossiness and ink absorption are also the best.

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.
