Printing Process
01
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.
02
Ink Preparation
Discharge ink needs to be mixed with activator and pigment. When the mixed ink is ready, it is ready for printing.
03
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.
04
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 is revealed, and remaining chemicals are 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.
Not suitable for fabrics: Synthetic fibers (such as polyester, nylon) are usually not suitable for discharge processes because their dyes cannot be removed.
Environmental Factors and Safety
Environmentally friendly: Discharge inks usually use water-based formulations that have less impact on the environment.
Frequently Asked Questions
What types of fabrics are best suited for discharge ink printing?
Discharge inks perform best on 100% natural cotton fabrics, particularly dark or black cotton, where they can effectively remove the fabric's original dye.
Can discharge screen printing be used on synthetic fibers like polyester?
No, synthetic fibers such as polyester and nylon are generally not suitable for discharge printing because their dyes cannot be broken down or removed by the discharge paste.
Why does discharge printing feel softer than regular screen printing?
Unlike standard inks that sit on top of the fabric, discharge ink replaces the fabric's original dye, leaving a printed pattern that feels as soft as the fabric itself.
Is discharge ink environmentally friendly?
Yes, most discharge inks use water-based formulations, making them a much more environmentally friendly option compared to traditional solvent-based plastisol inks.
Why is the curing process necessary for discharge ink?
Curing involves heating the fabric, which activates the bleaching agent in the ink. This activation is what actually discharges the original dye and reveals the new bright color.
