Caution for use

For Water form roller, use AVANT W. For Metering, Fountain and Squeeze roller, “New W4”is recommended. But if you are using UV Wash for these positions, AVANT W is recommended.

Caution for installation

1. Do not touch the rubber with dirty hands since oil and grease will be the cause of ink pile.
2. 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

  1. 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] .
  2. We recommend cleanings at least 3 times a day ( around noon, early-evening and after the job ) .
  3. 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.
