I'm new to heat transfer and still working out some kinks. Thought I had it all figured out, but yesterday I got some random blue spots on a mug that I pressed. I'm using Forever Multi-Trans with a mug press, white ceramic mugs and an Oki C711WT printer. Not sure how to post a picture so I'll try to describe what's happening. The graphic I'm transferring is a single color design (blue text). The design on the transfer sheet looked fine, but when I removed the paper after pressing it, there were 4 or 5 random blue spots (faint, but still noticeable). The spots average about the size of the head of a pin, and are scattered randomly, some close to the design, others no where near it. Not sure how to avoid the problem. Any suggestions on what I might be doing wrong? Thanks.

There must be some stray toner on the sheet when printing. Check the sheets after printing. You can cut away those spots to not waste the sheet. I would start by checking your design to make sure they are not stray image pixels in the original artwork. Then I would open the printer and clean everything to keep etra toner from spreading. Lastly I'd check the drums to make sure they are in good condition.

Thank you for taking the time to answer. And yes, that makes perfect sense that it would be stray toner. I'll let you know what I figure out when I have a chance to trouble shoot. Thanks again!

Did you ever find out what the problem was? Did you have success with Forever Multi Trans? I haven't had any success using that paper so Im curious to find out if it worked for you and what settings you used?

Might also make sure that you have even pressure on your mug. That will also cause spot issues.

I agree with David that there is stray toner in the areas of those spots.

I'm inclined to believe it was stray toner, but removing all of the cartridges and trying to find the source proved unsuccessful. I gave up and have had great success sublimating the mugs with a Sawgrass SG400 instead. Too bad, because now I have this really awesome white toner laser printer that has been relegated to regular office printing. One of these days I'll make it live up to its full potential!

I'll bet if you open your original design and zoom into the area where the spots are happening that you will find some pixel of color in the image. Clear those and it will work fine!
