White area of jet pro papers

Using JPSS does leave some white which shows up on the shirt, so I do some manual contour cutting around the image (and remember this one gets printed mirrored). Some folks say this white area will wash out, but I haven't done and washed enough to know how long that might take.

3G and Opaque do put down that white layer which builds up the amount of transfer on the shirt so it starts to feel heavy.

This white layer is why people believe in contour cutting these transfers (with a cutter/plotter) so that there isn't that white layer showing through. It will then look more like a screen print as only the colorful areas are on the shirt instead of a "window" of colors.

Hello,
I'm wanting to print some designs on the jet pro soft stretch transfers and on the dark versions, but I have a couple questions. How does the white area of the paper transfer to the shirt? As in if my image's color doesn't cover the entire sheet and I don't trim the paper, will there be a white box? And if I want white in my design can I leave it blank and let the paper be the white section? On my dark versions I created borders because I didn't know if the white area transfers to the shirt?

I haven't used any of the papers before and I only have five of each so I was hoping to get it right on the first shot! Thanks for the help guys.

If you don't trim JPSS the polymer will show especially on pastels and darker fabrics. You have to trim around the image. JPSS is meant for light and white fabric. It will not work for dark fabric. Inkjet printer except DTG does not print white ink. So the void and white areas in the artwork will be blank. Therefore, the color of the shirt will be the color in the void and white part of the transferred image. You have to use opaque to have white in the white area of the design. You have to trim in and around the image to get rid of unwanted white material. Best tool to trim is vinyl cutter with registration marks sensor.
