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.
Benefits
UV Plate Technology
The Aluva N builds on ECO3’s experience and market leadership in analog and digital plate technology and combines advanced UV-sensitive plate coating 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 ECO3’s Prima EN232 aqueous alkaline developer system.
