And then the third type that works just like TT, the dye is 'gassed'
onto a transfer sheet and then wrapped around mugs etc and put in a
heated 'mug cooker', the image is transfered to the mug.
I once fixed a PC in a shop that did this, and brass signs that were
printed the same way, and it does work for pcbs etc, because I asked
em for a sample print!
Problem was it was expensive, it was an a3 epson converted to bulk ink
feed, and they paid 1250ukp for it and would only get the paper/ink
from the same supplier because of the warrenty, and they said 'its not
cheap to run' as the ink is expensive and the papers worth more per sq
inch than paper money.........
