Forgot to mention, we're print/flash/print/flashing the white, and it looks great until it goes through the dryer.
Andy did you ever figure out the dye migration. I use only Green Galaxy inks and I am printing my first 50/50 shirts and I got an additive from Ryonet called warp drive that lowers the cure point to 270-280. I know this post is old but maybe it can help someone else.Thanks, Tom! I think I might try going that route, I just hate to have to add another screen to the job. I was looking today at the Green Galaxy Comet White again, and it says you can use it on cotton/poly if you add a "compatible low-cure catalyst." Trouble is, how do I know what's compatible? Sent them an email, hoping they reply. If I don't hear anything in a couple of days, I think I'll try the Matsui undercoat stuff. I'm going to play around with the heat, too, and try to find a magic window where it cures, but doesn't migrate. Kinda got my doubts that'll work, but it would be nice if it did!
So I am wondering, if you could mix the Supercover white with other regular Permaset colors and still get good opacity on darks, then couldn't you mix any of the Supercover colors with the same regular color to sort of get a blend of the benefits and the price?
