The distance between the printing plate and the substrate

color photos, pictures, oil paintings, gouache and other paintings use color changes to express objects and space. The process principle of reproducing color originals on fabrics by silk pigment printing is based on visual theory. According to the principle of color separation, with the help of electronic color separation machine, the color manuscript with complex hue changes is divided into monochrome dot positive plate of yellow, magenta and cyan. After the color separation positive plate is made into silk plate by photosensitive plate making method, the monochrome images are overprinted together with yellow, magenta and cyan coating printing paste, and the color manuscript is reproduced on the printed fabric

1. Positioning device. The error of color eye tone printing overprint is allowed to be within 1mm. In order to make the overprint accurate, the cooperation of positioning device is very important. Printing the color image of eye tone on paper is a new type of thermal insulation material. In the color printing of eye tone on fabric, one method of positioning is to use the locator of the printing plate and the printing table to position the color plates, and the other method is to use the eye position measurement method when manually printing small area images. The mechanical and manual printing adopts the positioner to overprint accurately and have high production efficiency. The matching gap of the positioning nail in the positioning hole shall not be greater than 0.1mm

textile silk printing tables are equipped with different types of locators to ensure accurate positioning. There are two forms of textile silk printing: one is that the printing plate does not move, which is mostly used for manual printing; One is the cloth version, which is mostly used for flat machine printing. There is no fixed mode for the form to be adopted, which depends on the specific situation. At present, the positioning of printing table is generally plug-in

2. Printing essentials. In the printing process, whether mechanical or manual, there are many factors that need to be adjusted or controlled. Especially for manual operation, various factors should be adjusted by people. For silk printing on fabrics, many small and medium-sized enterprises are facing a series of difficulties, such as low-end product positioning, fierce price competition, high accounts receivable, insufficient capacity utilization and so on. The key points of operation are: concentrate on ideas, push the scraper evenly, the angle should be consistent, the pulp should be balanced, and the pulp should be clean. In the process of operation, it is necessary to operate, check and check each other at the same time, and ensure accurate overprint, uniform thickness and consistent depth. The principle of printing plate arrangement is first deep then shallow, first thin then thick

if the hardness of the scraper and the table top does not conform, it should be re aligned, which has a great impact on the eye tone printing. Dot printing requires a high degree of clarity. The non textile surface is smooth, the texture is crisp, not easy to deform, and the dot definition is guaranteed. While textiles have moisture absorption, the surface is not smooth, and there are fabric holes. How to print dots clearly and skillfully is very important

the influence of color giving amount on eye color printing is multifaceted. In the textile color block screen printing, the color giving amount only affects the depth of the printing tone, but has a much greater impact on the dot color printing, because the colors in the dot printing pattern are realized by the overlap and juxtaposition of dots. If the paste layer of a color is slightly different, it will be immediately reflected in the performance of the tone. Therefore, it is necessary to strictly control and master the consistency of the color giving amount (pulp giving amount)

the distance between the printing plate and the substrate has little effect on the quality of the finished product when using additives in textile color that should meet the gb9685 standard, but it is very important in dot color printing, which should attract the attention of the operator
