In order to research and control the surface tension of the water-based ink-jet ink, and ensure the printing quality of the ink, water-based ink samples with different surface tension are prepared and the roundness, volume, speed and the tail length of the drop are measured in order to analyze the influence of surface tension to drop state. The influence of the main components to the surface tension is discussed through testing the surface tension of the water-based ink-jet ink which has different components. The result shows that the surface tension of the water-based ink-jet ink has big influence to the drop state, so the suitable surface tension is the key to guarantee the printing quality. And the kind of the resins influence the surface tension, the influence of adding different kinds and levels of surfactants to surface tension is different.

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.

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.

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.

Piezoelectric Inkjet Printing is the main ink-jet printing at present, and drop state will have great influence to ink-jet printing quality, so the ink-jet drop state of edible ink is researched based on piezoelectric inkjet printing. The viscosity of the ink is adjusted by the way of adding different levels of resin, and then the samples which have different viscosity are got. Drop state is observed through drops observatory which installs Spectra Polaris nozzle (35pl), then the speed, volume, tail length and roundness of the drops are measured at certain moment in order to evaluate the influence of viscosity to ink-jet drop state. The result shows that viscosity has big influence to ink-jet drop state, when the viscosity becomes larger, the speed of drops becomes smaller, the variation of volume is not so obvious, the tail length of drops becomes smaller and roundness becomes larger accordingly, until the viscosity is 10mPa•s, the tail length is the smallest and roundness is the biggest, the drop state is the best , when viscosity is bigger than 10mPa•s, the tail length will become bigger and roundness smaller.
