1060 Aluminum Plate for Positive PS Plate

A positive-working PS plate is a planarographic printing medium featuring a pre-applied photosensitive resin coating on an aluminum substrate. The aluminum base undergoes specialized treatments—including electrolytic roughening and anodic oxidation—to create a durable printing foundation optimized for lithographic processes.

The prevalent choice for PS aluminum substrate production is the 1060 aluminum alloy sheet. Beyond PS plates, this material is also employed in crafting thermal CTP, photosensitive CTP, and UV-CTP plates. Gwangyang Aluminum’s PS plate substrates typically span widths of 400mm to 1600mm, with standard thicknesses ranging from 0.10mm to 0.50mm.

Given the stringent demands for surface finish and planarity in PS plate manufacturing, achieving top-tier PS aluminum substrates necessitates specialized leveling techniques post-cold rolling.

To eliminate flaws like deep gouges, indentation streaks, or impact marks during PS plate production, Gwangyang Aluminum Aluminum leverages cutting-edge leveling processes. This ensures the aluminum sheets meet rigorous quality benchmarks.

Moreover, Gwangyang Aluminum integrates frosted airflow conduction technology to streamline plate production workflows. By employing electrostatic spraying, the system efficiently evacuates air trapped between the film and PS plate during exposure, slashing vacuum phase durations by 66% compared to non-frosted substrates. This innovation directly accelerates overall plate production cycles.
