Abstract
Disclosed is a presensitized plate, having an anodized layer and recording layer provided on a support for a lithographic printing plate, wherein the anodized layer is provided by subjecting an aluminum plate to graining and anodizing treatments. The presensitized plate has wide development latitude, makes it difficult for scratch-like non-image portions to be generated and facilitates handling in usual operation.
