In the gravure process, we often encounter some process failures. These processes not only occur in the printing process, but also in the pre-press and post-processing areas. The occurrence of these failures often results in: loss of processing costs, repair costs, and raw material costs; confusion in the order of printing operations; efficient production is hindered, costs increase; and valuable printed products cannot be provided, resulting in a decline in market competitiveness.
In the gravure printing, the problem of process failure occurs mainly in the following aspects.
Pre-press field: incomplete product planning; poor composition of printed materials; incomplete design; poor plate making; poor printing materials, etc.
Printing field: poor printing effect; hue does not match: size is not accurate; poor printing adaptability; poor printing conditions; inaccurate printing precision; incomplete printing equipment; poor operation of printing press;
Post-press processing field: poor lamination film; poor adaptability of bag making; poor adaptability of filling; poor post-processing performance (boiling, steam sterilization); good light resistance; poor storage and storage performance; : Convenient performance and so on.
The following are some examples of common faults in gravure.
The smear, also called the non-pattern part phenomenon, refers to the phenomenon that the ink that has passed through the squeegee is transferred to the printing paper, which is a kind of malfunction unique to gravure printing.
The main disadvantages of the resulting pollution are:
1, printing speed is fast;
2, printing ink viscosity is hard;
3, less amount of thinner;
4. Use a large amount of solvents other than No. 2 (standard) and No. 3 (dry slow) desiccant;
5, the drying of the ink is slow;
6. The scraper is in a wave state, the blade is too probing, the blade pressure is too large, and the scraper angle is not allowed;
7, the plate around the roller is too thin.
