Abstract

PURPOSE: To eliminate moisture water when printing with a lithographic printing block by largely improving the detecting capacity of the block by using an aluminum block treated by etching process.
CONSTITUTION: An aluminum block etched with alkaline solution or electrolytically etched is used as a water-eliminating lithographic printing block. The etching easiness depends upon the purity of aluminum in the block. Low purity aluminum is more readily etched than high purity alluminum. The stripes and metallic light on the surface of aluminum block are erased and whitened by a suitable etching process. When the block is excessively etched, the surface of the block is blackened to produce rough surface to reduce the detecting capacity thereof. When the block is less etched, the stripe of the block due to rolling direction is retained on the surface of the block less effectively.
