What is discharge printing? Definition and significance in textile printing
Discharge printing—also known as bleaching or color-removal printing—is a specialized printing process in which the existing dye in a colored textile is chemically removed and simultaneously replaced with new dye. This results in a particularly soft, breathable print with vibrant colors, without any additional layers of dye on the fabric. This process is primarily used on high-quality cotton textiles.
Arsonists, your creative partner for high-quality textile finishing in Munich, uses discharge printing to achieve exceptionally soft and durable results. This process offers a natural feel and a sophisticated print finish—ideal for designers, brands, and event merchandise—making it perfect for projects where quality and style are paramount.
What makes the discharge print so special?
- Soft to the touch: The ink doesn't sit on top of the fabric but is integrated into the fibers—the result feels just like the unprinted fabric.
- Breathability: The fabric remains fully breathable, making it ideal for T-shirts or hoodies.
- Durability: Colors fade less and remain vibrant even after many washes.
- Vibrancy: The prints are bright and high-contrast, especially on dark fabrics.
How discharge printing works
- Preparation: The fabric is dyed and prepared for the printing process.
- Applying the bleaching agent: A special printing paste containing active ingredients (usually sulfur compounds) is applied to the fabric.
- Heat activation: Through heat treatment, the dye layer of the fabric is removed in the desired areas and simultaneously replaced with new pigments.
- Fixation: The colors are permanently locked into the fiber—resulting in a soft, long-lasting, and vibrant finish.
