Cosmolight®

Plate–making manual

Cosmolight®

We, the pioneer of Printight®, a water–wash letterpress plate, have commercialized the world's first water–wash flexo plate, Cosmolight®. Our superior photopolymer technology produces a water–wash plate which is also durable to water–based ink, as well as solvent based and UV–ink.
This revolutionary plate eliminates the need to use toxic, environmentally damaging washout solvents , and allows processing by "Water", one of our most abundant natural resources.
Discover a fresh advantage with Cosmolight®, the leading water–wash, environmentally friendly flexo plate.

Key advantages

  1. Washout in plain tap water with a small amount of mild detergent.
  2. Eliminates the use of dangerous hydrocarbon and hazardous washout solvents.
  3. Plates are "press-ready" within an hour and "press-down time" is dramatically reduced.
  4. Print quality is excellent with both water-based and alcohol-based ink.
  5. High resolution and reproducibility provides sharp details.
  6. Excellent ozone resistance.
  7. Excellent ink transfer.
  8. Excellent resistance to solvent ink. (type NS, NH, QS and QH)
  9. Thickness tolerance allows for "kiss" impression settings.
  10. "A closed washout system" allows for repeated use of the washout solution.
