Aluva N

A durable, versatile negative-working plate, specifically designed to be used with UV CtCP systems produced by Lüscher.
Aluva N

Are you looking for a negative-working plate that can be used for a wide range of purposes? This is it: the Aluva N serves all your printing needs from the smallest sheet-fed printer to the largest commercial operation. This versatility is a result of the unique combination of two technologies: UV-sensitive plate coating together with the grained and anodized aluminum substrate.

Expect outstanding performances, such as a stable ink/water balance, low dampening levels, and a fast start-up – even after a press stop-down. Integrate Aluva N with a computer-to-conventional-plate system by Lüscher, and exceed those expectations.

Key benefits

  • Specifically designed for CtCP applications
  • Run lengths up to 250,000
  • Outstanding lithographic print results
  • Capable of 200 lpi in combination with Lüscher’s Xpose! UV setters
  • Perfect for a wide array of applications, including stochastic screening

Features

UV Plate Technology

The Aluva N builds on Agfa’s experience and market leadership in analog and digital plate technology and combines advanced UV-sensitive plate coating together with proven high-quality grained and anodized aluminum substrate. The result is a UV-sensitive plate uniquely made for computer-to-conventional-plate (CtCP) applications.

Optimum Press Performance

The plate delivers outstanding lithographic performance: fast start-up, low dampening levels, stable ink/water balance and fast restarts after press stop-downs. You benefit from easy handling with excellent durability and can achieve run lengths of 250,000 and more impressions (depending on the imaging and press conditions). Aluva N is a ‘no-bake’ solution for high run lengths. UV-ink capability is also given without baking.

High-quality Imaging

Aluva N is a negative-working plate with very high image contrast. Exposed on Lüscher’s proven XPose! UV setters, the plate is capable of 200 lpi (80 lpcm) AM and 25 μ FM imaging and is appropriate for a wide range of high-quality printing applications including stochastic screening.

Fast Exposure and Proven Plate Processing

The plate combines fast, accurate and wide-latitude plate exposure with simple and robust processing and there is a wide range of compatible processors available from different manufacturers. For best printing results and longest chemistry bath life, use Aluva N with Agfa’s Prima EN232 aqueous alkaline developer system.
