I designed a shirt for a race several weeks ago. I just washed one of them and noticed some of the white ink faded/washed out. I used a flash dryer and I'm thinking that maybe the outer edge of the image might not have truely reached 320. Should I put them back under the flash dryer? For how long? Is it to late to do that? What should I do? I still have the shirts. Is there any way to ensure that the same won't happen to the others before I give them to customer? I don't want to burn the ink or cause it to crack. Please help!
