At least get your flash dryer working. A heat gun isn't a flash. Or a dryer. It's a time waster and a pi$$-off-your-customer device if you're trying to do anything other than print shirts for your own amusement. Even a real flash dryer isn't the best for an even cure across the design, since the center gets hotter than the edges. And, you've gotta quit calling it "paint". It's ink. Not trying to be harsh on you, 'cause I understand everyone starts somewhere, but if you're gonna sell shirts, and especially a line of shirts, your reputation will go in the crapper right off the bat if you're shipping shirts that are poorly cured. You've also got to have some means of actually measuring the temperature of the ink as it cures. Otherwise, you're just hoping it's cured, or you're burning shirts.
