The merits of water-washable flexo plates

Our AquaGreen water-washable flexographic plate not only contributes to reducing environmental impact, but also achieves short-time plate making. In addition, high quality is maintained even in long run printing with a large number of prints.

Short-time plate making

Minimum time washout contributes to efficient and comfortable plate-making for everyone.

Productivity more than 3 times in comparison with solvent plate.

Plate making process details

High quality Long run printing

You will have minimal dot gain and consistency in long printing run.

AquaGreen are hard to gain paper powder, and have excellent ink-transfer.

AquaGreen have excellent ink resistant, wear resistance,weatherability.

Environmental load reduction

Development can be done with tap water (hot water of 40 to 50°C with surfactant added).

No need for solvent reclamation system. VOC emission will be eliminated.

Remarkable improvement of the productivity.

Shortening of the wait ime for press.

Quick reprocessing at the time of a trouble.

Cost effective processing.

Solvent & waste fluid processing free.

High speed plate processing reduces the cost for lighting and fuel.

Sumitomo Riko technology

AquaGreen was developed by combining manufacturing technologies cultivated by Sumitomo Riko such as polymer material formulation technology, high-precision molded sheeting technology, structural design technology, characteristic and plate making evaluation technology, etc.

AquaGreen’s features (Digital plate)

Feature(1) Halftone reproducibility

The influence of oxygen hardening inhibition, which is a demerit of digital plates, is lessened, and it is possible to reproduce halftones as designed.

With AquaGreen, halftones are highly reproducible as designed (Ø16μ = 175Lpi / 1% Ø16μ is easily reproduced).

Image control in platemaking work is easy, and image data processing and platemaking work is simple.

Structure Details

Feature(2) Halftone tone

With AquaGreen, the gradation of the halftone micro dot diameter is high, making clean, sharp print reproduction possible.
