If it's a 50/50 blend, you have to use a low bleed polyester resistant ink, or you'll get the bleeding problem. Especially on hoodies.

"Bleeding", also known as dye migration, occurs when residual dyes in a garment migrate their way into the ink film. The cause could be with the garment (not properly prepared for printing or as a result of the finishing method in manufacturing) or the inks (not properly cured). Bleeding can be controlled on most garments through proper controls on ink selection, application and curing.

you are using a low bleed ink which is the right ink for the job. the dyes may be migrating anyway due to excess heat. try to keep your over temps to no more than 340 degrees. in thes situation it would be better to cure longer rather than hotter.
