Re: Sweat Shirts If They, the shirts are 50/50 cotton polyester then you have dye migration. You will have to do one of two things: 1.Print an underbase in white and FLASH IT!!! This will slow down or stop dye migration. 2. If you are using a light colored ink print an underbase and flash it then print it again and properly dry it. OR you could use 100% cotton sweats (they are usually 90/10 cotton polyester. |
