The main reason for this problem is the poor absorption of ink by PVC. It is very difficult to dry completely by ink volatilization, especially in a large printing area, its drying time will be more than 48 hours, and the ink adhesion is very small, a wipe is off.
Since there are few special inks to print PVC materials, ordinary inks have to be used to print PVC adhesive materials. In fact, there is a way to easily solve this problem, interested counterparts might as well have a try.
resolvent:
Use bright light and fast dry ink, add 3% red dry oil, 5% Central Asian brand ink god, with varnish instead of cleaning oil blending until suitable for printing.

Some customer manufacturers with this method printed a batch of bottled water trademark, quality is very good, by customers.
