In order to standardize packaging and printing, please pay attention to the following requirements:
1. When packaging and printing, first check the CTP plate for dirty spots, scratches, etc., if any, use an eraser to draw it off.
2. Pay attention to the proportion of the ink when printing and color mixing. The color should not be too dark or too light. When there is a template, the color should be adjusted according to the template. When there is no template, the color should be adjusted according to the whole.
3. The printing press must be cleaned every day, and the printing cylinder must be wiped clean to avoid ink marks during the second printing.
4. During the printing process, the printed sheets must be checked frequently to avoid unnecessary printing problems, such as ink feces, dirty spots, etc.
