What are the important points of screen printing mesh and plate making? There are the following points
1. Use a suitable photosensitive adhesive and familiarize yourself with the photosensitive adhesive.
2. The environment in which the photoresist is applied must meet the requirements, usually in a dark room or in a place with low light.
It is absolutely impossible to apply under strong light, otherwise it will easily lead to pre-curing of the photoresist.
3, the printing plate must be strictly in accordance with the steps of the printing plate, the vacuum effect directly affects the exposure effect of the printing plate.
4. After rinsing and developing, it is necessary to check the development effect properly, check the graphic hollowing effect, and do not meet the requirements.
Must be corrected in time.
5, when comprehensive inspection, not only check the pattern development effect, but should be comprehensively inspected, including the stretching effect, coating
The cloth effect, the development effect, and the like, and the correctness of the content should be checked even when necessary.
6. After the end of the printing, the plate should be dried and placed in a cool place for use.
Also of note is the main technique of screen printing mesh: the hardness of the squeegee. Generally, when printing on a hard print, a soft squeegee can be used, so that the pressure applied by the squeegee can make the layout and the substrate sufficiently contacted to improve the printing effect. The wear resistance of the scraper. Since the squeegee and the screen plate are in direct contact, there is friction every time the squeegee is applied. Therefore, the squeegee is required to have good wear resistance, lubricity and a certain mechanical strength, so that the friction can be minimized when squeegeing.
The precautions for screen printing meshs are the above. If you don't understand anything, feel free to contact our business staff.、
