Here is an article I wrote for Printwear a couple years ago. It still rings true. Summer is the worst time for ghost images to occur, with heat and humidity on the rise on the Northern Hemisphere right now. I have had an inquiry every other day about somebody having ghost issues and so here is the info yet again. An addition to this article I would say is that now we are seeing ghost images that sometimes go from the back to the front of the shirt or around the print and it happens IN the dryer, not at the end of the dryer. The only cure for that (pun intended) is to use a non-ghosting white. We use the Rutland version M3 9000 for the toughest ghosting issues.
