Soft hand additives and reducers for plastisol inks can achieve amazingly soft prints by allowing inks to asbsorb further into shirt fibers as opposed to just sitting to top. These additives allow for a medium softness and brightness on light garments and a medium softness with a transparent/vintage look on dark garments depending on the ratio of additives to pigment.
Discharge printing is a dye replacement process used to achieve the brightest and softest possible prints on dark garments. Plastisol pigments are combined and reduced with waterbased discharge additives to produce soft vibrant dischargable inks. As these thin layers of ink are force into the shirt fibers they begin to remove the dye of the garment and replace it with the color being printed. Heat cures the inks and completes the discharge reaction. The end result is a must-feel product with unsurpassed comfort and washability. You're left with a print that should never wear, crack or fade because the ink isn't sitting on top of the shirt, the fabric is actually re-dyed.
Waterbased inks are medium opacity and will provide soft and vibrant prints on light and medium colored garments - prints on dark garments will appear more transparent and can give a vintage effect. Unlike PVC based plastisol ink, waterbased inks use water rather than plastic to bind the pigments. This not only makes waterbased printing printing the most ecologically friendly option but also means superior comfort and washability.
