1) Underexposure:
A, the thinning of the photosensitive layer is too easy to appear pinholes.
B, the edges of the pattern or wire are prone to sawtooth.
C. The number of screen prints dropped.
D. Screen recovery is difficult. Patterned shadows tend to appear on screens that have been removed from the film.
2) Overexposed:
A. The pattern will be distorted, the fine lines will be finer, the low-key meshes will be enlarged, and the highlights will be reduced.
B. Difficulty in unloading, and there is residue in the leaked part so that the ink does not mesh.
C. The template becomes brittle.
Therefore, before the plate-making, the exposure ruler must be used to determine the exact exposure time, so as to produce different requirements of the screen.
