Analysis of common faults of UV varnish

v. uneven surface coating, stripes and orange peel phenomenon

main reasons:

the viscosity of varnish is too high

2. Coating roller QCP (the mass circulation polymer is too coarse and not smooth.

3. The pressure is small and the weight is lighter and uneven.

4. The coating amount is too large.

the leveling property of the varnish is poor.

solution: reduce the viscosity of UV varnish and reduce the coating amount. The pressure is adjusted evenly. The coating roller should be ground and polished. Light leveling agent can be added.
