Hi

I've just recently sublimated 8 Windsor mugs with a small image on either side of the mug on a white background. I've since noticed the faint outline of the transfer paper is showing up slightly off white. I've checked the white in photoshop and it's ok the only thing I can think of is I'm cooking too long or hot, although the images i've done previously don't show any signs of this. That said this is the first I've done with such a large area of blank white on the mug. I'm using Trupix paper Sublinova inks cooking in halogen oven, 3 mugs for 8min 30sec @200. I also put plain inkjet paper between the silicone wrap and the transfer paper to stop any possible marks getting on mug from the wrap.

Thanks in advance
