Is the standard printing method used by the garment screenprinting industry. It uses polymer based inks that harden into solids when heated to 300 degrees. They are designed to sit on top of the garment and in some cases the deposit can be pretty thick (or as we affectionately call it . . . bulletproof).
Here is the image of the plastisol ink deposit. When compared to the discharge, it is obviously thicker as it sits atop of the garment. It is the opacity of the ink that is blocking the color underneath.
