Hi, I have a bussiness that prints photos on cases for iphone. I am using a adapted printer that uses the printing head of Epson R270 and eco solvent ink that prints on cases made of plastic polypropylene. I am experiencing a lot of troubles with the resistance of the ink. It scratchs very easy and discolor very fast. I need a help to solve this problems... what are the drying time for this ink? what coating/drying should I use? Should I change the printer? PLEASE HELP ME!
