Sublimating arm sleeves is a simple process that requires no jigs or special accessories. In addition to using settings 380 degrees for 45 seconds at light-to-medium pressure, you can employ a couple other techniques.
First, lint-roll the product before sublimating and make sure to remove any wrinkles from the product. Then, use a generous bleed edge on the artwork to make the alignment of the product onto the transfer an easy process.
Use a repositionable spray mount to lightly spray the transfer to assist in getting the sleeve and transfer to the heat press (transfer on top) without it shifting out of place.
