Need help quick!!! I have a customer that sprung a design change on me last minute from screen printing to a heat transfer design. I have heat transfer paper, JetPro SS, but the design is not showing up on on the dark shirt I need to print on. I have tried different settings on the press but still no luck. Itshows up a little bit but definitely not enough. Any suggestions and need to find a solution quickly. Thanks for any help.
