Control of Multi-color Printing Plate Quality of Offset Paper

(1) When printing, slightly increase the actual exposure so that the dot on the plate is slightly smaller than the dot on the film to compensate for the dot gain caused by the pressure during printing.

(2) In the baking process, the printing plate undergoes the phenomenon of elongation and shrinkage in the process of cooling and re-cooling. Therefore, in order to ensure the accuracy of overprinting, the baking version is generally not advocated when performing multicolor printing.

(3) The school edition should be proficient and accurate, reduce the number of school editions as much as possible, and avoid overprinting due to artificially deformed plates.
