Printing Process
Design & Plate Making
First design the pattern and transfer it to the screen plate. Screen printing plates need to be coated with a photographic emulsion, and through exposure to harden the emulsion to form a pattern. The part of the emulsion that is not hardened will allow the ink to pass through, thus forming a pattern on the fabric.
Ink Preparation
Discharge ink needs to be mixed with activator and pigment. When the mixed ink is ready, it is ready for printing.
Printing
Placing the screen plate on the fabric, the ink is evenly scraped across the screen, and the ink is transferred to the fabric through the open part of the screen.
Curing
After printing is complete, the fabric needs to be heated to activate the bleach in the ink and complete the discharge process. After curing, the color of the pattern on the fabric is revealed, and the remaining ink and chemicals are finally removed by washing.
Suitable Fabric
Cotton Fabrics
Discharge inks are best used on cotton fabrics, especially dark cotton fabrics.
Other Fabrics
While cotton works best, it can also be used on other natural fiber fabrics, though the results may vary.
Synthetic Fibers
Synthetic fibers (such as polyester, nylon) are usually not suitable for discharge processes because their dyes cannot be removed.
Environmental Factors & Safety
Environmentally Friendly
Discharge inks usually use water-based formulations that have less impact on the environment.
Frequently Asked Questions
Q1: How does discharge ink achieve bright colors on dark fabrics?
Discharge ink works by removing the original dye of the dark fabric (bleaching it) and replacing it with the new pigment in the ink, resulting in highly vibrant colors that stand out on dark materials.
Q2: Why does discharge printing feel softer than other screen printing inks?
Unlike plastisol inks that sit on top of the fabric and create a thick, rubbery layer, discharge ink penetrates and replaces the fabric's original dye. This leaves the printed pattern feeling as soft as the fabric itself.
Q3: Can I use discharge ink on 100% polyester shirts?
No, discharge ink is not suitable for synthetic fibers like polyester or nylon because their dyes cannot be deactivated or discharged by the formulation. It is highly recommended to use 100% cotton fabrics for the best results.
Q4: Is curing necessary for discharge ink printing?
Yes, curing is a critical step. The printed fabric must be heated to activate the chemical reaction that discharges the original dye and sets the new color. Washing the fabric after curing will remove any leftover chemicals.
Q5: Are water-based discharge inks eco-friendly?
Yes, water-based formulations of discharge inks are generally much more environmentally friendly and safer to work with compared to traditional solvent-based printing inks.
