Fully Automatic UV varnishing machine if there is a failure to use how to solve the problem:

       Film surface streaks or wrinkles failure causes: high viscosity varnish coating; varnish coating coating coating amount is too large; varnish coating on the surface of the printed matter ink layer wettability is not good; Fully Automatic UV varnishing machine's rubber rollers and the pressure between the embossing cylinder is not uniform. Solution: add a small amount of diluent to reduce the viscosity value of the coating; reduce the coating amount of varnish coating; adjust the varnishing machine's rubber rollers and pressure between the embossing cylinder to exclude the stripes.Fully Automatic UV varnishing machine after calendering, the surface of the surface is easy to fracture (thicker paper is more pronounced) Fault causes: calendaring in the temperature is too high, so that the printed materials reduce the water content, the paper fibre becomes brittle; calendering, the paper fibre becomes brittle; calendering, the surface is easy to fracture (thicker paper more obvious) The paper fibres become brittle; calendering pressure, so that the print extensibility, flexibility, poor; post-processing process conditions are not appropriate; varnishing coating after the processing of poor suitability. Solution: reduce the calendering drying temperature, and take effective measures to change the water content of the printed materials; reduce the calendering pressure; adjust the post-processing conditions, so that it is with the printed materials (after calendering) suitability match.
