Ruian city Galit for you to explain the solution to the glazing machine failure:

First, the film surface appear streaks or wrinkles

Cause of failure :1. High viscosity of glazing coating; 2, glazing coating amount is too large; 3. Glazing coating is not good for the wettability of the ink layer on the surface of printed matter; 4. The pressure between the rubber roller and the imprint roller of the glazing machine is not uniform.

Solution :1, add a small amount of thinner, reduce the viscosity of the paint; 2, reduce the amount of glazing coating; 3. Adjust the pressure between the rubber roller and the imprint roller of the glazing machine to eliminate streaks.

Two, printed matter after pressing, the surface is easy to crack (thick paper is more obvious)

Cause of failure: 1. The high temperature in the pressure light reduces the water content of the printed matter and makes the paper fiber brittle; 2. High pressure in pressing light makes the extension and flexibility of printed matter worse; 3. The selection of post-processing process conditions is not appropriate; 4. Poor processing suitability after glazing coating.

Solution: 1, reduce the pressure light drying temperature, and take effective measures to change the water content of printed matter; 2, reduce light pressure; 3. Adjust the processing conditions to match the suitability of the printed matter (after pressing and polishing).

Three, after pressing light, the blank part of the printed matter is light, and the light part is discolored

Causes of failure: 1, ink drying is poor, ink layer solvent resistance is not good; 2, coating solvent has a certain effect on the ink layer; 3. The coating layer is not completely dry, and the residual solvent is high.
