Avatar V-ZH

Chem-free violet printing plate which requires zero heat for plate production. It combines outstanding lithographic quality with excellent durability and eco-friendliness.

Avatar V-ZH

Overview

Avatar V-ZH is Agfa Graphics’ 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, as well as 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.

Agfa Graphics offers fully integrated newspaper prepress solutions that come complete with CtP, clean-out unit (COU), printing plates and Arkitex workflow software.

Key Benefits

  • The absence of a preheat unit reduces investment cost, saves energy and gains you floor space. It also means your air conditioning will no longer need to run full blast.
  • Linear behavior on the press throughout the print run
  • High robustness on the press (run length, dot gain, press roll-up...)
  • Flexibility: UV-capable for semi-commercial and special applications
  • Very high image contrast after clean-out and gumming, allowing an easy visual inspection to avoid mix-ups on press
  • Fully daylight resistant once cleaned out
  • High scratch resistance
  • Suited for high-quality Arkitex Sublima screening

Features

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.

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.

Avatar V-ZH chemistry-free printing plates form a very attractive solution combined with the high-volume plate production system Advantage N and the high-speed clean-out unit Attiro ZH. 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 Agfa clean-out units can easily be upgraded to the preheat-free version.
