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
