With the development of the times, screen printing machine used in China's printing industry in the proportion of more and more high machine, screen printing machine working process is composed of 4 elements, here we have to carefully understand these elements.
1 screen printing ink
Screen printing machine can use solvent printing ink, UV ink and a variety of functional paste, printing ink should be chosen according to the substrate material, test.
2 silk screen printing plate
Three ways to prepare silk screen printing machine screen: direct coating method, direct film sticking method, indirect diaphragm sticking method. According to the type of substrate, plate making process to fully consider the screen tension, mesh size, the version of the film thickness, the important parameters of screen frame size. According to the ink type selecting water-soluble or oil working photoresist.
The 3 clamp
Must make good stability, a good fixture, to ensure consistency and position accuracy of the overprinter. The highest point of the tangent plane plane fixture parallel to the screen plane, is equal to the diameter of gear pitch circle diameter and the substrate surface is circular clamp shaft end.
4 screen scraping gum
Screen scraping gum is a source of pressure screen printing machine, plays a role of transmission and the leakage of ink. Planar substrate with rectangular cross section is usually a rubber blade, curved substrate usually choose a triangle section scraping gum, CD disc can be considered a special plastic scraper, rough surface with soft squeegee, smooth surface, use hard squeegee.
The only familiar with the flow of elements to screen printing machine, printing out the good product, also has the very big help to the operation screen printing machine!
