Dear all,
I'm facing with problem of varnish coating on the surface of printing sheet. It is not dry completly after 8 hours of curring time. Normally, our standard for curring time for varnish coating is 8 - 12hours. So, I need advice from all of you, do we have any formal method to check drying of varnish coating ? pls support!
