You can't go wrong with Imageclip Laser Light. That is all ever used for light garments. No trimming and self weeding. Good for pastel if you print with spot color black or if you don't mind the shirt color affecting other spot colors you can other spot colors also. But the point is there is not polymer window. One caveat the manufacturer says it will not work with gradient or photo. I overcame that limitations by converting the image to high resolution RGB color halftone.
If you want to evaluate the transfer buy or ask free pre-printed and/or pre-weedied from one of the vendors.
I gave up on inkjet printer long time ago after I tossed 5 printers due clogging.
