Screen-Printing on posterbord

Hello,



I've been trying to do some artwork for sale. I normally print t-shirts with regular plastisol inks. I found posterboard does decent when curing the ink. I have found that too much handling results in peeling of the inks off the board. Does anyone have any suggestions that can make my life easier? And keep my production's promise of quality?



Thanks



I did not find the right solution from the internet.
