Printing film is a transparent film that carries graphic and text information, a key medium for traditional printing plate making. It needs to transfer the designed patterns to PS plates or resin plates accurately through exposure and development processes to achieve mass printing.
Positive film has its emulsion side facing down, with the graphic part opaque and the non-graphic part transparent, suitable for PS plate making. Negative film has its emulsion side facing up, with the graphic part transparent and the non-graphic part opaque, mostly used for resin plates.
Laser film has high precision and is suitable for printing fine patterns. UV-sensitive film has strong weather resistance and is often used in special fields such as electronic circuits and packaging printing.
