sub ink bleed through paper problem

[logobear]

We have noticed that if we sub a mug with wide coverage, then do one with a much smaller print area then some of the previous image is transfereing onto the next mug where it is not wrapped in paper.
We are using TMT SubMagic paper which we think gives weaker results that our previous (unwatermarked) product.
We use a DT 180, and have just changed the element.
Do all papers bleed through and impregnate the heat element, possibly marking future mugs?
It might have been happening for a while and we havn't noticed, or it could be a new problem?
Any ideas??
Thanks
Phil

You could use a second sheet of paper wrapped around to protect the mug from any ink left on the blanket. Must say i haven't had this problem though - I'm using xpres paper, don't know if it makes a difference.

Can't you just cut your transfer the same size with the print positioned on it where required? I don't see the benefit in cutting the transfer smaller than the largest wrap used as you will often get a certain degree of ink transfer.

sounds like cheap thin paper to me

when I heat my mug press up with the scrap mug in it bits of old designs have started to appear on this mug, just shadowy but you can see it . I'm using sublimation paper from coralgraph and ar Tanium inks. I thought perhaps I had the heat a little too high but happy with the mugs I'm making (although not done many)

get some cheap greaseproof paper
and wrap your mug in it
it's cheap so disposable works a treat

I just used a new mug without print - wasting 1 mug is cheap compared to a new blanket.

I'm with Andrew on this one, and would suggest that whatever the print area of your design you cut the mug paper out at the same size - ie, top to bottom on the mug, and to the handle. As well as eliminating ink contamination from the heater band this will also enable you to use your PC or Mac to set the position of your design on the product for greater consistency.

This is how we do them anyway. Laying out to pre-defined artwork templates dor each of the mug styles.

Hope this helps.

we also cut and design the paper to fit the mug, it is so much quicker and easier. When your doing 200 to 300 mugs having the design in the same position looks far more professional. if for some reason I have not cut it right and it doesn't fit the mug I just use normal paper on top.
