High Quality Discharge Ink for Screen Printing - China Suppliers & Factory for Fastness on Dark Fabrics
Bright colors
Discharge inks can achieve bright color effects on dark fabrics, especially for printing on black or dark cotton fabrics.
Soft feel
The printed pattern feels soft, consistent with the feel of the fabric itself.
Environmental protection
Water-based formulations are usually used, which are more environmentally friendly than solvent-based inks.
Durability
The printed pattern has good washable resistance and wear resistance.
The printed pattern feels soft.
Good environmental protection.
The printing process is more complex and requires certain technical experience and equipment.
Some colors, such as pure black or vivid red, can be difficult to achieve.
Through the reasonable selection and use of discharge ink, the effect and quality of screen printing on dark fabrics can be significantly improved.
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.
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.
What are the main advantages of using discharge screen printing ink?
Discharge screen printing inks allow you to achieve bright color patterns on dark fabrics, provide a soft feel that is consistent with the fabric itself, and offer good washable and wear resistance. They are also environmentally friendly as they typically use water-based formulations.
What types of fabrics are suitable for discharge printing?
Discharge inks work best on cotton fabrics, especially dark or black cotton. They can also be used on other natural fiber fabrics with varying results. However, synthetic fibers like polyester and nylon are not suitable because their dyes cannot be removed by the discharge agent.
What are the limitations of discharge inks?
The limitations include a restricted range of compatible fabrics (mainly cotton), a more complex printing process that requires technical experience and proper equipment, and difficulty in achieving certain colors like pure black or vivid red.
How does the curing process work in discharge printing?
After printing, the fabric must be heated (cured) to activate the bleaching agent within the discharge ink. This heat activation completes the discharge process to reveal the pattern's colors. A final wash is then required to remove remaining ink and chemical residues.
Is discharge ink environmentally safe?
Yes, discharge inks are generally more environmentally friendly because they typically use water-based formulations, which have a lower environmental impact compared to traditional solvent-based inks.
