Screen printing printing process looks very simple, a screen printing squeegee and a cloth only. However, the screen printing ink delivery process and the concept of the average person are much more complicated because the screen printing ink has been rotatingly moved during the printing process. Rotating centrifugal force and screen printing squeegee exert pressure on the ink at the same time.
The general accuracy of the screen will not consider these issues. Because the theory is always a lot, but the practice may be only two or three steps. A lot of very good teachers may also have not studied this issue. From practice to practice itself is also a major way to explore and develop screen printing technology. Talk about the screen printing process of ink transfer, we mainly explore the ink transfer process and affect the ink transfer key points, if replaced by our daily printing to achieve the goal, then it is how to accurately control the accuracy of lines and outlets, with the most Good parameters to achieve this process.
First of all, the ink squeezed from the screen printing surface with a squeegee it, I think this is not the problem. There are two situations. First of all, the offset printing, gravure and resin printing technology, including printing ink transfer process is to make the printing ink and printing products in close contact with the ink delivery. We look back and forth at the screen printing ink transfer process, we will find that the ink cover knife in the screen after the mesh filled with ink, we scraper scraping the purpose is to make the screen and the printed product in close contact with the mesh The bottom of the ink is in contact with the printed matter stuck to the top of the print. Therefore, the most important function of the screen printing squeegee is to achieve precise line contact with the screen printing, rather than with a lot of force squeeze the ink through the screen. This is a theoretical basis for precisely controlling the amount of ink.
That is because the application of screen printing industry is very wide, said the ink squeezed through the screen, in order to get the maximum amount of ink, the most typical is the use of round head squeegee printing to achieve the goal, it and We demand the precise control of ink requirements are not the same. In this article I take a round blade squeegee screen printing in a special case of view.
This article mainly talks about the transfer process of ink and discusses how to accurately control the amount of ink. The angle of screen printing squeegee greatly influences the amount of ink printed on screen printing. The best wiper angle recognized at home and abroad is 75 degrees, the same point of view of the match. Ink must be made of screen printing ink delivery process to understand the precise that the exact transfer of ink screen printing process is a product of many factors eclecticism. Through experiments, we can understand the screen printing squeegee angle, blade hardness and ink viscosity, ink cutting force between scratch in the short process of interaction. On this basis will be made with the best printability inks. Ink suppliers should consider that ink parameters are a very important subsystem in screen printing and experiment, from the point of view of screen printing ink.
