1 The smoothness of the absorbent paper requires that even slight wrinkle marks affect the smoothness of the photosensitive layer;
2 The water sprayed on the screen must be in the form of a fan of water falling on the screen, so that the entire screen surface is covered with a uniform layer of water film, so that the photosensitive layer of the film can be equilibrated at equal speed. Adhere to the screen, do not drop water droplets on the screen or the photosensitive film at the water droplets will be thinned or perforated;
3 When scraping off excess water, the squeegee should be smooth and smooth, never stop. Otherwise, there will be a trace at the standstill, resulting in poor smoothness of the photosensitive film surface, affecting the uniformity of the ink in the printing process;
4 In any case, water spray dry sticking method, if you do not pay attention there will be the above problems, the screen printing rate is lower than the photosensitive adhesive screen, it is only applicable to the production of medium and small reticles.

The film is a non - stretch and non - directional thin film produced by the melt salivation.
There are two ways of single layer salivation and multi - layer co-salivation.Compared with blown film, it is characterized by high production speed and high yield.At the same time, because it is the follow-up process of flat extrusion film, such as printing, compound and so on are extremely convenient, thus widely used in food, medical supplies, textiles, flowers, daily necessities packaging.
