ink quality: The chemical composition of the ink is crucial in determining how well it bonds with fabric fibers. These properties significantly impact the ink's ability to adhere to the fabric, ultimately affecting the quality of adhesion.
temperature before applying the powder: The air temperature during printing is crucial. Keep the room under 25°C, and set the pre-heat plate to 40-42°C. If either temperature is too high, ink may dry too quickly, affecting bonding. If too low, the ink may not cure properly or bond with the fabric.
fabric type: Different fabrics have varying levels of porosity and react differently to temperature and ink. Some fabrics may require specific temperature settings for optimal adhesion.
humidity: Humidity levels in the environment can also impact the drying and curing process. High humidity may slow down the drying/curing, affecting the ink's ability to adhere properly.
printhead: After ruling out all other possible causes for a persistent issue, replacing the printhead may be the last resort. Printheads have a limited lifespan, typically ranging from 1 to 2 years, with some lasting longer depending on usage and maintenance.
By addressing these factors and ensuring a proper match between materials, equipment, and printing parameters, you can minimize the risk of cracks / edge peeling and improve the overall quality and durability of your prints.
How to prolong the life of not just the print but whole shirt
Choose natural detergents and avoid chemical-based ones, especially those with harsh chemicals.
Wash clothes at lower temperatures to prevent wear.
Use a slower speed cycle for both washing and drying to reduce the risk of fabric tearing and print cracking.
Iron at a low temperature to avoid damaging the print through heat.
