This is a new problem for me and is a nightmare. When I sublimate a small 3"x3" color image on white paper and wrap it around the white mug using a cactus wrap, I get light blue blotches that show up on the white areas of the white mug. I showed my graphic source and they can not figure it out. The paper is white and the images are on a new white back ground. The cactus wrap is new. Where are blue blotches coming from? Is it heat? I tried backing off to 375 and the blue showed up on a few and only cooked 6 instead of 12 mugs. These problems have cost me lot's of time and money. Has this every happened to any one else? Thanks for your help.

I ran across a similar problem, cept the spots were yellow. I believe what caused my yellow spots was an old print, I did an order for a few dozen 11 oz mugs and had printed a few extras in case of mistakes and kept them in case of a reorder. A month went by and I decided to test one on a 15 oz mug and got yellow spots all over. The age of the print was the only thing that I saw different compared to my normal process. Since you say it's new paper, maybe there's too much ink on the paper or something?

JB is probably right on the mark...in sublimating material... you have to make sure there is no lint or foreign matter on the shirt.. I use tape to wipe the area of the transfer to get rid of extraneous matter...same with the mugs I wipe them down first.

Thanks I will make note of the age of the prints too. The blue spots are random. Every mug is different. I am thinking it's my printer maybe. You can not see the blue if it is the printer.

I had a issue with small blotches and it was caused by dust particles on the transfers. I ruined several cups before I figured this out. ... JB
I wipe every thing off now too. It's blue blotches from where? I will work on this more. If I don't I'll just drop the white back ground images. There must be a better solution.

Thanks and have been wiping them off. You have to. So where is the blue coming from? Strange I think.
