Whites not white enough!

[twinsgran]

I know, it sounds like a laundry problem, but not quite!lol!
I've recently printed a couple of jigsaws and the whites are slightly yellowish. Could this be a heat problem or pressure maybe? Any ideas please?

[Paul]

to much heat??? what jigsaw are they and what settings you used for pressing?

[twinsgran]

Hi Paul. They're wooden puzzles and we're using 180deg for 60 secs. The other puzzles have come out fine, but this particular one has a lot of white in it and half of it seems a bit yellow.

when i had yellowing on my mugs i lowered temp but increased time. never had this problem on jigsaw tho.

I'll try lowering the heat a bit then and see if it helps.

As sublimation printing doesn't use any white - it has to be a heat issue. I think you may be scorching the jigsaw.

Is the original artowork's white actually white, or is the printer laying down some yellow?

Are you using anything in-between the transfer and the heat press? i.e. silicon sheet etc?

[twinsgran]

Justin......I use a silicon sheet underneath and a greasproof paper on the top.

pisquee......The original artwork looks white to me. If I can work it out, I'll try to post a photo of it.

Can you use the colour picker tool thingy in Photoshop to see if it is completely white?
