N95-VCF
N95-VCF offset plates combine outstanding lithographic quality with easy handling, excellent durability and eco-friendliness.
N95-VCF belongs to Agfa’s range of photopolymer offset plates for the newspaper industry. Like other violet offset plates, it is sensitized for visible lasers emitting at 405 nm, but, instead of requiring a chemical developer for processing, it is designed for chemistry-free operation.
This chemistry-free plate works with all mainstream violet CtP units currently in use at newspaper print sites across the world. It is the most environmentally-friendly plate on the market. Using a pH-neutral clean-out solution, it saves 100 percent of water and eliminates the usage of developer and replenisher.
主要优势
- 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 a faultless physical image inspection and as such avoiding confusion or mix-up on press
- Once cleaned out, the plate is fully daylight-resistant
- High scratch resistance
特性
Imaging & Processing Principle
During exposure, the violet-laser diode starts the polymerization of the image area, which is completed in the first section of the COU. Subsequently the plate is gummed with a dedicated plate gum, during which process the soft, unexposed non-imaged area is easily and cleanly removed.
Durable Substrate
N95-VCF 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
Although a chemistry-free plate, press operators will readily accept it as it looks, feels and behaves as any other metal offset plate. With its high contrast, a quick visual check will reveal any possible errors (e.g. imposition). N95-VCF combines fast, accurate and wide-latitude plate exposure with chemistry-free processing, while ensuring predictable, consistent performance on press.
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. Just like with ThermoFuse solutions, violet chemistry-free offers major advantages in maintenance time.
