So I just spent ages taping up 36 mugs (Yeah I know, I'm slow) getting the warps put on, finally after a long day I get the oven on and cook the first 12.....
Well, they've come out as white as they went in! Bloody hot but no trace of any print whatsoever!!!!
Only explanation is that they're not sublimation coated, yes, they should be. Ovens at right temp, transfers are subli ink...all usual newbie questions covered ;-)
Oh well, customer won't be collecting these on Monday :-(
