Sublimate/Cook a mug twice!

[AdamB]

Just thinking here - will it affect a design if a mug is sublimated/cooked twice?

As an example, say I have a design that is very popular but is personalised. Could I cook the mug with the design on it and then add the personalisation at a later stage?

I only ask as I have a mug that I always keep in the mug-press when I turn it on (to warm up) and it is now YELLOW from the amount of times it's been heated and cooled. I keep waiting for it to break when I dunk it but it keeps going like one of those duracell rabbits!

Why do you dunk it?

I put my "dummy" mug back in the press and allow both to cool naturally when I've finished a batch.

for no other reason apart from habbit!

that plus I quite like the hiss/fizzle sound that it makes :-)

Its is a strangely satisfying sound :)

If you try to sublimate a second time you'll restart the process of the already printed area, this will bleed over onto your blanket and will no doubt smudge.

I have done this couple of times. one side was printed and other side was left for future tests. (mugs was a rejects) and I always use paper or teflon strip. I must say I never noticed any change in the "old" picture.wired as I would expect what Justin just said but honestly. picture was fine.

Now Paul mentions it I do this too - print smallish image to test so i can do another one or two prints to same mug and I have never noticed the original image deteriorating.My dummy mug in the press has no image on it but has been heated many many times - maybe I will put something on it and see how it survives.

For testing, I often press a mug with up to several prints around it - one after the other. Each pressing does "blur" or soften the print that's already there. I notice it immediately, but it's fair to say that many people probably wouldn't. I guess it depends how sharp the design was in the first place.

My dummy mug goes an awful yellow-brown colour, but it takes dozens of presses before you start to notice.
