We use Union Ink POLY line for printing on synthetics. The white is very opaque, doesn't have any dye migration, and is easy to print.
Dye migration issues with white ink
Hello friends, My shop is having dye migration issues more and more. I'm not sure if everyone else has noticed it. We used to have a problem every once in a while, but now it happens more often than not. The biggest difference is in Teamwork's jerseys. At least 1 of every dozen will grab dye from the jersey. The awkward thing is that a run of uniforms will show a variance. Some will be bad, and others will look just fine. Are these companies using dyes that have a lower vapor point? Dryer isn't too hot. Our operation/inks have not changed, but the problems occur more frequently. My printer says he has tried wilflex poly-white, but it didn't affect much. I'd like to see it for myself. Does anyone have suggestions for white inks? We've been using bright tiger for quite a while.

I have used Union Poly white and Chrome Yellow on Teamwork poly performance shirts and mesh shorts and still have had dye migration problems on Black, Navy and Maroon garments from time to time at 360f in a 30' gas dryer. Some garment batches seem worse than others. We have been experimenting with a new additive on the market that lowers the curing temp to 275 - 300f. Wash tests look good so far on A4 Teamwork goods. Lower temperatures seems to be the only solution, not switching inks. We have also moved to more 100% nylon shorts and shirts which are almost as cheap and dont bleed at all at any temperature. Its all about the polyester dye they choose to use. You dont know there is a problem until it's too late...sometime overnight the bleeding up through the ink occurs. I hate when that happens.
I did printing for Warrior Sports for years.Printed all types of polyesters.Some are easy some are so loaded with crappy dyes that are not set by the material manufacture that no matter what you do ,it will bleed.Test,use lower temps, good inks and inform them about the colors you have issues with. Maroon and forest are always big bleeders.
I did a job one time for Northwestern University Wildcats.One color , white on black shorts. The print looked great.After a week they brought them back and the prints turned purple and brown.I sprayed a test area with water on a white test shirt and sure enough the white had purple and brown all over it.The dyes were crap and not set.They never used that supplier after. Only the good Lord knows what was in that dye.
