cooling mugs

[jennywren]

I cool with fan, when I cooled in warm water the inside had lines appear when the made a cup of tea or coffee. its in one of the threads I think started by me

I agree with Simon, but if I was to dunk it would be in near boiling hot water.

I do not use any cooling just print and leave to cool and have not had any issues(touch wood)

[mgibbs]

I dunk in warm water now.

I used to get ink bleeds (fuzzy edges) on too many mugs when left to air cool.

One thing to note when leaving to air cool is that I have had a situation where I was putting the mugs too close together when cooling. Basically they were touching and what was happening is that the image of the mug that had just come out of the press was also transferring over to a mug that had been sitting there for 5-10 minutes and subsequently printing a very light image on that mug as well.

Air cooling has always worked for me but I now make sure there is about 5mm plus between each mug.

im a hot water dunker and not cracked one yet.... gives me a chance to give them a quick clean before i ship them out...

I have to admit to air cooling myself, never had a problem.

Air,
only ever had problems with water, - cracked handles, crazing inside, or just getting things wet that should be dry, - simpler is better for me !

Hmm, TMT states for my HTP 616 Plus,that after cooling the mug goes back on a lower heat (so that the picture gets re-glazed?) I take it you chaps don't do this second heating?
