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 addition of the Attiro Cleaning Module (ACM) even extends the main cleaning cycle for Attiro COUs to 12,000 m² of plate consumption. Furthermore, the two intermediate cleaning processes at 4,000 and 8,000 m² are executed as part of an automated process that starts with a simple keystroke on the Attiro display and requires no further intervention from the operator.
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.
Benefits
“The Attiro ZH clean-out unit and the Avatar V-ZH printing plate enabled us to move our CtP lines closer to the press console”We benefit from the Avatar V-ZH’s stable, linear behavior throughout the entire print run.

Unique cascade concept in the cleaning module
This section consists of three tanks:
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.
Gum 3: 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.
Efficient drying
In the drying section 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.
A low energy LED bar takes care of final curing of the plate in the drying section.
Fully flat plate transport
This ensures plates are not bent by rollers as they travel through the clean-out unit.
High speed
A processing speed of up to 400 plates per hour makes the Attiro ZH the perfect match for high-production, heavy-duty environments.
