Outline

  • Toyobo has 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. The CTP (computer-to-plate) technology is to be able to create higher and clearer reproduction of screen dots and letters.

    Analog plate

Feature

Key advantages

    • 1. Solvent-free in the plate making process, toxic-free for the operator
    • 2. Total plate making time is less than one hour.
    • 3. Built-in Flat Top Dot is reproduced due to TOYOBO original LAMS technology.
      It achieves less dot gain and stable printing quality for long run job.
    • 4. Microcell and HD screening system can be applied to improve printing quality.

Plate-making process

Washout by tap water with a small amount of mild detergent at 40℃.
Eliminate the use of dangerous hydrocarbon and hazardous solvents.

  • 1 Back Exposure

    Expose UV light from the back side of COSMOLIGHT® to make floor first.

  • 2 Laser Ablation

    Depicted digital images through an IR laser head to the mask layer directly.

  • 3 Main Exposure

    Expose UV light.

  • 4 Washout

    Washout the exposed plate with COSMOLIGHT® washout unit.

  • 5 Drying

    After wiping off the surface moisture by sponge roll, dry in hot air dryer.

  • 6 Post-exposure

    Expose UV light again to complete photo-curing.

  • Please follow all the laws and regulations in your district. (Please refer to SDS for details.)
What type of laser equipment is used?
All laser equipments suitable for processing LAMS (Laser Ablation Mask System) plates are applicable.
Why does CTP technology can reproduce higher resolution of screen dots, fine lines and letters than analogue process?
The CTP technology enables digital images to be depicted through on IR laser head directly from computer to the mask layer. So, it can control UV light diffusion and can make a sharp dot.
  • All products are produced with a quality control system as certificated by "ISO 9001" for the world.
