If the surface coating strength of the paper is poor, the surface may be peeled off and peeled off during the printing process, which may contaminate or even damage the blanket. Frequent cleaning and replacement of the rubber may result in a decrease in printing efficiency and quality. At the same time, peeling is also the main reason for the loss of elasticity of the surface of the blanket.
Peeling during printing
This figure shows the peeling phenomenon caused by the splitting force of the ink being greater than the tear resistance of the paper, or the low quality of the paper-bonded paint and the glue.
Solution:
Use a slightly softer ink
Reduce the viscosity of the ink (add ink)
Set the press correctly to make it work properly
Slightly raise the temperature of the ink roller (constant temperature system)
Reduce printing speed and reduce peeling force
Select a blanket with good release characteristics
Select high quality paper
