Problems and solutions in UV offset printing process (SEVEN)
Analysis and solution of print-through and through-back failures of printed matter
Possible causes and adjustment methods for print-through: The ink contains too much non-drying oil, and the drying speed of the ink should be increased. If the ink viscosity is low, it can be mixed with high-viscosity inks, but ensure that the inks are evenly mixed before use . The printing pressure is high and the printing speed is slow. The printing pressure and printing speed should be adjusted appropriately.
The reason and adjustment method of the penetrating back: If the ink layer is too thick, you can switch to the ink with thin ink and high color density. If the paper is thin and transparent, the pressure should be reduced, and the paper with low transparency should be used first.
