DSF

I am wondering whether any of you have had or heard of this problem:

Yesterday I printed 9 mugs, and when finished my tongue feels burnt - like when I've drunk a cup of tea that's too hot. :frown: Problem is that this happened last time I did a run of mugs and lasted about 4 days. I don't have the same problem when using my flat press though.

I'm using Ricoh GXe7700 with sublijet ink, printing on mugs with BMS DM14 mug press. I'm in a room 16ft x 12ft, no heating. One small window open. Do I need more ventilation (and a thick jumper )or is there something else I should be considering?

Thanks

Are you remembering to let them cool down before drinking out of them?!

Other than that, if you're using the same inks with the flatbed press, and don't experience this problem (and all other things being equal) then the problem points to the mug press - maybe something in/on the blanket evaporating when it gets hot.
Can't hurt to get the MSDS and COSHH sheets for the ink though from the manufacturer/supplier.

Thanks, pisquee, I'll follow that up

MSDS sheets can be found here for our inks : http://www.sawgrasseurope.com/technical ... sublijet-r
Any vapour produced during heat transfer is essentially water, and should not produce any effect on the manipultor. Some very sensitive people may react, but not any more than, say , to cigarette smoke. The oral symptoms you are experiencing may point towards chemicals evaporating from the mug press - suggest you ask Martin

Thanks Sawgrass.

Once my symptoms have gone I'll run the mug press with some blanks but no ink, to test whether it's the press that's causing my problems.

... or could be the coating on the mugs, as this wouldn't be involved when using your flat bed press
