- New W4 has excellent hydrophilicity, which provides thin and uniform water film for a long time.
- Dimensional change against eco-friendly inks is minimal that it ensures stable use for a long time.
- Ink buildup on rubber is minimal that it ensures stable use for a long time.
- Ensures easy adjustment of water supply because New W4 offers wide water film.
- The softness of the rubber surface provides a longer life of the plate.
- Resistant to IPA and fountain solutions.
* Hardness(Shore A) : 20 ･ 25 ･ 30
* color : Dark Green
The smaller the contact angle is, the better hydrophilicity it has.
Caution for installation
Do not touch the rubber with dirty hands since oil and grease will be the cause of ink pile.
Use dampening roller cleaner [NEW MATICLEAN ECO] before running.
* Do not clean the rubber with chlorinated solvents and polar solvents such as ketone.
How to maintenance
- Use the automatic washer for water form rollers as well when changing colors.
Make sure the solvent does not mix into the water pan.
For water metering rollers, wash manually with [NEW MATICLEAN ECO] . Apply [NEW MATICLEAN ECO] on a cloth and wipe the roller until the ink is completely cleaned.
Wipe off the solvent with a dry cloth for finishing. If the ink does not come off easily, use a normal ink roller wash first and then use [NEW MATICLEAN ECO] .
- We recommend cleanings at least 3 times a day ( around noon, early-evening and after the job ) .
- Special color inks such as gold, silver, fluorescent, UV tend to pile-up on rollers easily and are difficult to come off. Therefore, repeat the cleaning process several times.
* Do not clean the rubber with polar solvents such as MEK or chlorinated solvents such as Trichloroethylene.
