Red 'burn'

[TomR91]

Hi,

I'm new to sublimation mug printing, and have had a few successes, but i can't get rid of this sort of red 'burn' around the base off the mug, its only here, i've tried a number of things like turning the heat down, adjusting the time, turning it upside down to rule out it being the press, but nothing seems to work.

Any suggestions?

Thanks,
Tom.
