Help with Something I Dont Understand

JPSS for light shirts (best with white shirts) is for inkjet printers (with pigment inks). One doesn't really need to cut around this one, as the polymer window doesn't show up on white shirts, but would be noticeable on gray. Then there are inkjet papers for dark shirts; with these any area not printed with ink is going to be white, so you need to cut that part off. But the white layer adds thickness and stiffness to the paper, so these transfers have a heavier hand and are less durable than something like JPSS.

There are also laser transfers that would need cutting, but there are also self-weeding versions of such paper that don't need cutting.

See the transfer sub section on here for a lot more info

Got it. Thanks!
