Whether it is a semi-automatic screen printing machine or a fully automatic screen printing machine, there are many kinds of materials that can be printed, such as plastic, cloth, electronic components, paper, etc., then, what are the specific requirements for these substrates when using a screen printing machine?
First of all, it is necessary to have a correct quality concept to ensure the quality of each substrate product; Secondly, the working environment should be kept clean, and all appliances should be well maintained. Specifically, the requirements for printing materials when the screen printing machine is working
Specific performance in the following points:
1. The film base and polyester film of the negative need to be highly transparent. At the same time, the film surface should be on the front of the negative. We often find that some users use the film surface on the opposite side of the negative, for offset printing of the positive film, the use of this negative plate, the quality will not be guaranteed. Because the screen printing plate requires that the image of the film surface should be in close contact with the sensitive adhesive layer of the film plate. At the same time, the density of the film needs to be greater than D3. At the same time, the density of images and text everywhere in the negative needs to be higher. Hand engraving mask should not be used as screen printing plate negative. The negative should be made of photographic negative with high hardness. At the same time, in the use of negative printing money, it is necessary to clean it with detergent or dust roller.
2, screen printing screen should have a certain high tension, very low tension loss, and should have high tension stability, good wear resistance, as well as low water absorption, good acid corrosion resistance.
