The uv varnish and ink cure to form a hard film with a small tip. To peel off the film, it should be a piece of stiff, shiny surface like a fish scale. If it is not completely cured, paraffin-like small pieces will be used for peeling off.
Testing method:
1. Press the crucible with the paper and ink layers by hand. If the surface is cured and the lower layer is not cured, the surface layer will be smashed.
2. Put the printed paper on the surface for 24 hours. If it is hard to smell completely, it will smell like a varnish or ink.
3. Draw a light surface with a pin and observe with a 200x magnifier. The scratch is jagged and the surface is cured.
4. Use acetone or ethanol to drip over the ink layer. If the ink layer dissolves quickly, it indicates that it is not cured.
