Looks like that side of the print isnt cured and the plastisol is bleeding. Are you curing with a flash dryer or small width belt dryer?

That is strange. You have heavy bleeding on the top of the shirts and almost none on the bottom of the design. I have only had this happen once. I was printing white ink on green blend shirts. They wanted a vintage look. I took the white ink and mixed it about 70 percent reducer to 30 percent white ink. I printed a test print and didn't run it though the dryer. It sat for the whole run of about 200 shirts. The shirts that went though the dryer were perfect. The test print that sat did the same thing. It bleed out past the white ink like in your photo. It had to be the reducer that did it. Keep in mind mine sat for about an hour.

Content aware ink?

But seriously, figure out how you did it as you might need it for a print later, I think it's a cool effect!

Is your ink well stirred?
Is this consistent in location?
Have you used this ink batch successfully before?

Plasticizer is leaching. Get the batch # from the bucket and retain a wet sample. Send to Triangle. I would also try to replicate what happened. Definitely sounds like an ink issue.
