Mixing Jacquard SolarFast Thickener with Jacquard SolarFast Dyes increases their viscosity so you can use them for screen printing. This is the easiest dye-based system for screen printing available — no heat, steam, or chemical fixing is required when you use Jacquard SolarFast Dyes. The process leaves fabrics completely soft, lightfast, and washable, and your images are permanent. Your screen and tools will clean up easily with water. Compared to traditional pigment-based inks, Jacquard SolarFast Dye creates a relief-free surface and unique effects that can’t be achieved with ink.
