Attiro ZH

Saving money and the planet while cleaning out your violet chemistry-free plates? Use Attiro ZH, a clean-out unit that uses a unique cascade concept and zero heat.

Attiro ZH


Meet Attiro ZH, the high-speed clean-out unit for your violet chemistry-free plates. Its groundbreaking cascade technology makes your operations both more productive and sustainable, as the concentrated gum is reused in three cascading sections. In this way, the non-imaged areas are effectively removed and there is no risk of oxidizing. The result: minimal gum consumption and little waste for a maximal clean-out effect. Full maintenance, with our dedicated circulation cleaner ATTIRO CareClean, is only required after 8,000 m².

The Attiro ZH clean-out unit forms a very attractive solution combined with the Avatar V-ZH preheat-free chemistry-free printing plate, and the Advantage N platesetters.

Key Benefits

  • No preheat unit results in reduced CAPEX, up to 80% energy savings, more floor space, and no buckling of plates because of heating/cooling
  • Minimal gum consumption for maximal clean-out effect; less transport of gum bottles
  • Extensive bath life,  with full maintenance only required after 8,000 m²
  • Fully flat plate transport through the clean-out unit leaves plates unbent by rollers
  • Easy visual check and no mix-ups on press thanks to high-contrast image on the gummed plate
  • High speed (up to 400 plates per hour) makes it the perfect match for high production, heavy-duty environments

Unique cascade concept


Gum 1: 95 % of all non-imaged areas are removed from the plate.

Gum cascades into the first tank from the second tank and is sprayed on the plate to remove the non-imaged areas. The imaged areas are bound to the substrate and therefore not washed away by the gum. As most of the clean-out happens in this first gum section, it contains most of the cleaned out emulsion. The exhausted gum is drained off.

Gum 2: The remaining non-imaged areas are removed from the plate.

The gum mix from the third tank cascades into the second tank, removes the remaining non-imaged areas, and then cascades into the first tank.

Gum3: A layer of fresh gum is applied to prevent the plate from oxidizing the grained and anodized aluminum.

The final clean-out step is carried out with diluted gum fresh from the bottle, thus ensuring a perfectly clean plate. The fresh gum and water from the tank in the third section then cascade into the tank of the second section. 

Dryer section: The plate is dried to enable immediate handling, independent of format.

Hot air is blown through a pair of air tubes, which dries the plate on both sides. As a result, further handling of the plate is immediately possible.

LED curing

A low energy LED bar takes care of final curing of the plate in the drying section.
