hiya
I am a newbie on here and am having a couple of probs.

I am using large 15oz mugs and when producing these the base edge of the mug does not seem to take the image and looks duller and fuzzy. The time I have been given for these mugs is 15 seconds, 170 idle and 180 cooking time.

The other problem is that with the large latte mugs they also seem to suffer from the same problem and also slip out of the jacket.

I am using richoh 3000 printer and the df18 that bms sell.

Must point out I purchased this kit from another supplier that has since gone out of business.

The times I have seem totally different to what I find on here, but the small mugs look ok but will be experimenting tomorrow with times etc on here.

thanks

They're a big mug, and there's lots of ceramic in the base to absorb heat - you'd be best preheating the mugs on an electric hot plat or in an oven before putting the transfer on and pressing them - this should cure the fuzzy bottom problem.
To me though 15 seconds doesn't sound very long pressing time ... for mugs, we put them into a press around 190 degrees C and start the clock immediately and leave them in for 3 minutes.

hiya yes the 15 second bit is worrying me now. Does your 3 minutes include the idle temp of the press reducing due to the colder mug being put in the jacket and the time taken to warm up to the press temperature? Will try the pre heat idea.
Another question if I could please, why are mugs placed in cool water and not left to stand? ( as I do). thanks Nick

Our presses run at full temperature the whole time, and the 3 minutes already takes into account the press cooling down a bit with each new mug - although it doesn't cool down so much if we're preheating them. We adjust the temps of the presses dependant on how much the press cools with new mugs going in, which can be dependant on the temperature of the room that day. Our sublimation inks sublimate from 160 degrees, so with a press set to 180-200 (depending on the room temp, and the type of mug we're using) 3 minutes is plenty of time.

hiya, thanks time for an experiment now.

thanks

You cannot put large latte mugs in the same press, unless you are using the latte press jacket, due to the fact that they taper off, that is why you are finding them slipping out of the press.

hiya, oh yes I have a latte jacket, probably making the press too tight! thanks
