EasyWeed® Sub Block

Standard heat transfer vinyl isn’t designed for use on sublimated polyester.
If you apply regular HTV to a sublimated garment, you may experience “dye migration.”
Dye migration is when the sublimation inks in the garment bleed into the heat transfer vinyl and change the color of the HTV.
EasyWeed Sub Block is specially formulated to block most dye migration and leave you with a crisp finished product!
EasyWeed Sub Block is ideal for the popular digital camo and motocross jerseys!
You can even layer other Siser® materials on top to create a more colorful look!
