Inks for Polyester. Polyester is a synthetic fabric, engineered for properties that cotton does not offer. It is a more flexible fiber, making the fabric more tear-resistant. Polyester is one of the most challenging fabrics to print on due to dye migration issues caused by heating to around 300 degrees when the dyes start to bleed through. Since this heat is necessary for the ink curing process, it becomes a challenge to print on polyester.
