Advantages of using series 1 aluminum plate for thermal CTP plate:
Aluminum content of ≥99.50%, ≥99.60%, ≥99.70%, with the advantages of low density, high strength, moderate wear resistance, good formability, high stability, good surface treatment, etc.
Requirements for using series 1 aluminum plate for thermal CTP plate:
1.The aluminum plate surface must be clean, flat, without cracks, corrosion pits, spots, air holes, scratches, bends, print marks, peeling, loosened branching patterns, oil marks, etc.
2.The edges must be neat, without cracks or burrs.
3.The average roughness value Ra of the surface must be between 0.17-0.21μm to avoid damage to print quality.
4.Thickness tolerance allowed is ±0.003mm, width tolerance is ±0.5mm, length tolerance is 0 to +1mm, side curvature <0.2mm, diagonal deviation <2mm.
