The Recipe for EXP54LWZ, EXP54LWP, EXP52BMR, EXP64CRP, EXP24YWZ…. Also works for the EXP95NB, EXP99CNB, EXP94NAW, EXP35SSZ, and the Poly-tech fleece with possible screen changes due to the fleece fabric surface.
The reasons these inks are recommended on Polyester is because at 300 Degrees Polyester Dyes gas off and migrate into the ink altering the color. This is not unique to our poly windbreaker this is normal for all polyester garments. The print inks used are important, as well as the temperatures reached. Avoid getting the garment above 290 degrees or near 300 Degrees. The poly blocker protects against dye migration by absorbing gasses if the garment is over heated, and is a good safety precaution, also a good opaque base to cover camo. The Poly Blocker acts like a sponge, once it is filled it can’t absorb anymore, this is why dye migration on an Overheated/Misprinted garment can appear later once the blocker has absorbed all it can and the garment is still gassing. The catalyst helps create better adhesion to the fabric.
Washing the printed sample garment(s) after 24+ hours (so hardener has set) is recommended to make sure you have proper curing and ink adhesion.
