I did that.
A few problems though.
I only have the one design.
I'm fairly new at this and just recently started up the business.
I've never screen printed to a transfer before.
I only have a flash curer and even with the Raytek to check temperature I'm not sure if I can get an even gel curing of the ink. The curer I got from Silkscreeningsupplies.com seems to have a lot of cool spots and I'm constantly mooving the unit around to heat low temp areas to get an even curing.
Also, after reading some info on making plastisol transfers it doesn't seem as easy as I though, With the shrinking and registration problems. Thankfully, the design I made is only one color.
