Why is Plastisol Still the Best Screen Printing Ink?
Here are the top 5 reasons why Plastisol is the Best Screen Printing Ink & most sought-after ink by screen printers.
01. It Creates Vibrant Prints:
Plastisol ink creates vivid and vibrant prints that other ink can’t produce. Even with darker color substrates, it makes a vivid print. Unlike water-based and discharge inks, it layers on top of the substrate rather than absorbing it to the fabric so you can create bright and solid prints on any substrate.
02. Plastisol ink doesn’t dry out:
Unlike water-based inks, plastisol doesn’t dry out quickly, which screen printers appreciate who employ water-based inks. Plastisol has to reach the extreme temperature to cure, and it doesn’t harden in the screens during long press runs. On the one hand, it makes printing jobs much easier. On the other hand, print shops can reuse the screens in short order, which you don’t need to clean out between jobs. You can scrape back the excess ink back into the bucket for reuse.
