Pressing technique
In the context of sublimation printing, achieving high-quality, long-lasting prints relies heavily on the pressing technique employed. Applying even pressure throughout the pressing process is paramount to ensure consistent ink transfer and prevent defects that can compromise the final product.
When pressure is unevenly applied during pressing, the ink may not transfer uniformly across the entire design. This can result in areas with insufficient ink transfer, leading to faded or patchy prints. Conversely, excessive pressure in certain areas can cause the ink to bleed or spread beyond the intended design, resulting in blurred edges and distorted graphics.
Maintaining even pressure throughout the pressing process ensures that the heat and pressure are distributed evenly across the fabric, promoting optimal ink transfer and preventing these issues. This meticulous approach contributes significantly to the longevity of the print, as it helps the ink bond securely with the fabric fibers, reducing the likelihood of peeling, cracking, or fading over time.
Understanding the importance of pressing technique and applying even pressure is crucial for achieving professional-quality sublimation prints.
