Abstract (en)

[origin: EP0565006A2] A method for preparing a PS plate comprises the steps of treating an anodized aluminum plate with an aqueous solution of an alkali metal silicate having a pH ranging from 10 to 13 as determined at 25 DEG C, then treating the aluminum plate with an aqueous solution of an acid having a pH ranging from 1 to 6 and applying a light-sensitive layer onto the aluminum plate thus treated. The aluminum substrate of the PS plate is only slightly dissolved in an alkaline developer and this accordingly prevents the formation of insoluble compounds or sludge effectively, during development.
