The Relationship

Ink jet printing, as the key point of digital printing development, has already got some progress as technical be concerned, and also it has been used in industrial producing. But until now, ink jet printing still has some problems to be solved, include satellite droplet, droplet dimension, and spreading of droplet on substrate and so on. These problems involving parameters include dimension and geometry of the print-head, quality and characteristics of the control signal, surface tension of the ink, viscosity of the ink, characteristics of the substrate surface and so on. In this paper we just analysis the influence of ink surface tension to the process from jet to formation of the droplet by establishing mathematical model, but keep other parameters unchanged. At last, we get the relationship between ink surface tension and droplet parameters, so that it can be used as theoretical basement for print-head design and researching of ink.

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.

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 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.

The quality of ink-jet printing depends to a large extent on the technical characteristics of the selected equipment and the surface properties of the printed substrates. It is known that for digital printing it is necessary to use expensive paper with a special coating that determines the degree of gloss of the surface. Therefore, ordinary offset papers before ink-jet printing are covered with primers that ensure good fixation of pigment ink or dye on paper, a wide field of color coverage, characteristic gloss, which generally contribute to high quality of imprints. As you can see, the type of the substrate and the state of its surface has a very great influence on the quality of the imprints. Result of the research, it has been confirmed that not only expensive paper of a special purpose can be used for a drop ink-jet digital printing. High-quality color imprints can also be obtained on ordinary offset and coated paper, coated before printing with special primers based on interpolymeric complexes of polyvinyl alcohol, which will provide sufficient optical density, contrast of images, and expand the possibilities of digital ink-jet printing.

Nano-sized ceramic inks suitable for ink-jet printing have been developed for the four-colours CMYK (cyan, magenta, yellow, black) process. Nano-inks of different pigment composition (Co1–xO, Au0, Ti1–x–ySbxCryO2, CoFe2O4) have been prepared with various solid loadings and their chemico-physical properties (particle size, viscosity, surface tension, ζ-potential) were tailored for the ink-jet application. The pigment particle size is in the 20–80 nm range. All these nano-suspensions are stable for long time (i.e., several months) due to either electrostatic (high ζ-potential values) or steric stabilization mechanisms. Both nanometric size and high stability avoid problems of nozzle clogging from particles agglomeration and settling. Nano-inks have a Newtonian behaviour with relatively low viscosities at room temperature. More concentrated inks fulfil the viscosity requirement of ink-jet applications (i.e., <35 mPa˙s) for printing temperatures in between 30 and 70 °C. Surface tension constraints for ink-jet printing are fulfilled by nano-inks, being in the 35–45 mN˙m–1 range. The nano-sized inks investigated behave satisfactorily in preliminary printing tests on several unfired industrial ceramic tiles, developing saturated colours in a wide range of firing temperatures (1000–1200 °C).

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.

A ceramic ink was prepared, characterised, and subjected to continuous ink-jet printing. The optimum modulation frequency for printing was estimated. The surface free energies of several substrates were determined and different patterns of the ink droplets were printed on these. Phenomena occurring during the process were investigated. The drop-by-drop resolution and ink spreading were found to be dependent on the dispersive/total surface free energy ratio of the substrates. Ink drying was accompanied by powder migration in the droplets deposited on substrates with a surface free energy lower than the surface tension of the ink. Printing of multiple layers was accompanied by the appearance of ridges, splattering, and non-vertical walls. The causes of these phenomena are discussed in this paper.
