the reason:
(1) The ink dryness is too fast and the viscosity of the ink is large.
(2) Inclusion of impurities.
(3) poor re-solubility, the amount of ink remaining in the plate.
Approach:
(1) Drying is slowed by the following contact printing time.
High-speed rotary machine 0.015 ~ 0.02 seconds;
Medium and low rotary machine 0.04 to 0.1 seconds;
High-speed single sheet machine 0.1 ~ 0.15 seconds;
Low speed single sheet machine 0.5 to 0.6 seconds.
The number of seconds above is the time it takes for a good ink to be imprinted on paper.
(2) The hair blows onto the layout.
(3) Increase the true solvent and enhance resolubility.
