How to formulate the thickness of the screen printing plate according to the printing demand

The thickness of the screen printing plate refers to the thickness after coating the photosensitive resin on the screen. That is, the thickness of the screen printing plate is equal to the sum of the thickness of the screen and the thickness of the photosensitive film.

The thickness of the screen printing plate is determined according to the printing requirements. Usually the height of the ink layer after printing is closely related to the thickness of the screen printing plate. Under normal circumstances, when the screen printing plate used is thicker, the ink layer after printing is used. On the other hand, if the screen plate used is thinner, the ink layer will be lower after printing. In special cases, it is required to use screen printing plates of thick-film photosensitive materials with a thickness of up to 1 mm. For example: Making Braille The thickness of the screen printing plate is generally between 0.1-0.250 mm.

With the direct platemaking method, the thickness of the screen printing plate is obtained by coating the photosensitive resist several times. The coating is applied once and dried once. The required thickness of the screen printing plate can be obtained by performing the cycle operations in sequence.

In the case of indirect plate-making or direct-to-plate printing, the thickness of the screen printing plate is obtained by selecting different thicknesses of the photosensitive film according to the printing requirements.
