Reduces investment costs
The absence of a preheat unit saves energy and gains you floor space. It also means your air conditioning will no longer need to run full blast.
Avatar V-ZH is ECO3’s latest addition to the range of photopolymer offset plates for the newspaper industry. Avatar V-ZH requires zero heat for plate production. Based on the successful experience of our customers with the chem-free photopolymer plate N95-VCF, this newly developed plate technology supports the demand of newspaper printers to streamline production processes further and to reduce machine maintenance and servicing.
In addition, the reduction of waste and start-up time during the make-ready process, stability and linearity throughout the entire print run, and additional energy savings, will empower the daily production. Avatar V-ZH is sensitized for visible lasers emitting at 405 nm, and is designed for chemistry-free operation without any preheat process.
ECO3 offers fully integrated newspaper prepress solutions that come complete with CtP, clean-out unit (COU), printing plates and Arkitex workflow software.

Easy to use
Once plates are cleaned-out and gummed, image contrast is excellent, allowing an easy visual inspection to avoid mix-ups on press.
-
High quality
Avatar V-ZH shows linear behavior on the press throughout the print run. It is suited for high-quality Arkitex Sublima screening.
-
Durable
High scratch resistance and high robustness on the press (run length, dot gain, press roll-up…)
Imaging & processing principle
This preheat-free chemistry-free plate works with all violet CtP units currently in use at newspaper print sites across the world. During exposure, the violet-laser diode starts the polymerization of the image area. Subsequently, the plate is gummed with a dedicated plate gum, which removes the soft, unexposed non-image areas in an easy and clean way. Finally, the plate is cured by a LED bar close to the drying section.
Durable substrate
Avatar V-ZH plates provide a solid foundation for consistent press performance. Advanced electrochemical graining and anodizing yield the reliability and robustness needed on a newspaper press and the durability required for long press runs. The plate is UV-capable for semi-commercial and special applications.
High performance on press
With its high contrast, a quick visual check will quickly reveal possible errors (e.g. imposition). Avatar V-ZH combines fast, accurate and wide-latitude plate exposure with predictable, consistent, linear performance on press throughout the print run.
Easy maintenance and less waste
Chemistry-free solutions come with the benefit of a reduced environmental impact. No hazardous processing chemicals are used. The gum is pH-neutral and there is a substantial water saving. Violet chemistry-free offers major advantages in maintenance time.
Part of a total solution
Avatar V-ZH chemistry-free printing plates form a very attractive solution combined with the high-volume Advantage N plate production system and the high-speed Attiro ZH clean-out unit. The latter features a groundbreaking cascade technology and is characterized by minimal gum consumption for maximal clean-out effect. Its extensive bath life results in lower maintenance, while cleaning is easy and fast. Existing ECO3 clean-out units can easily be upgraded to the preheat-free version.
