Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
*could be a lot of things but......*The only time this happened to me was using an athletic white with a bleaching agent (hydrogen peroxide I believe) in it to try to block dye migration, probably the only bucket of plastisol I've thrown out over 1/2 full. Now we just use good Wilflex Poly white ink and why we won't ever....EVER.... try to save money on poly whites again. It was ~ 800 shirts for us, the customer took them at shirt cost to use as give-away promotional shirts, and we re-printed more shirts to replace the event order. We were damned lucky to get that too and I was happy to only be out ink and labor on the original shirts.
That was going to be my next question, if you went to 300 F on the dryer did the ghosting remain or disappear?
