The factors that affect the printing of soft line folding boxes are:
1. Environmental factors of soft line folding box printing: If the room temperature of the printing shop changes greatly, the flow state of the ink will change. The temperature and temperature of the general production workshop are controlled at (23 ± 5) degrees Celsius, and the humidity is 60% ± 5%. In addition, when using ink in winter, it should be preheated in advance to increase the fluidity of the ink.
2. Flexible line folding box blocking: blocking of the dots will cause the ink transfer volume to decrease, and the color of the printed matter will change. When blocking occurs, clean the printing plate with a solvent or a special cleaning agent, and take corresponding measures for the cause of blocking.
3, soft line folding box printing plate wear: printing plate wear will make the dots smaller and lighter, which affects the dot's ink load. As a result of plate wear, the overall color fades. Sometimes the abrasion of the white plate makes the amount of ink on the white ink insufficient, and the hiding power of the base color of the substrate is insufficient. At this time, the production of the plate should be stopped and the old plate re-plated. If the plate cylinder is collapsed by using the transition mesh wall, the plate cannot be deplated, and the plate should be re-made.
4. The rationality of the soft line folding box printing plate design: When designing the printing plate, we must fully consider the impact of the printing plate design on the printing process and post-press processing. For example, the color of half-dots in the half-dots jump area is about 80% and 5%, so it is easy to be gradual and grading. Change measures should be taken in advance.
