    摘要: Disclosed is a production method of an aluminum support for a lithographic printing plate, capable of stable and low-cost production of an aluminum support for a lithographic printing plate, the support being scarcely subject to generation of treatment unevenness called streaks or grainy unevenness ascribable to the different in the aluminum dissolving rate due to the difference in the orientation of the crystal grain. The aluminum support is produced by surface graining and then polishing an aluminum plate or by polishing an aluminum plate while etching it in an aqueous acid or alkali solution. The aluminum plate may be subjected to polishing and then to anodization or may be subjected to polishing, to surface graining, again to or not to polishing and then to anodization. A production method for producing a high-quality support for a lithographic printing plate, free of local unevenness is also disclosed.

    摘要: The invention provides a method for producing a support for planographic printing plates which comprises a step of roughening the surface of an aluminum plate and in which the surface-roughening step includes (1) a pre-electrolytic surface-roughening step of electrolytically roughening the surface of an aluminum plate in an aqueous hydrochloric acid solution, (2) an alkali-etching step of etching the roughened surface of the aluminum plate with an alkali solution, (3) a desmutting step of contacting the etched aluminum plate with an aqueous sulfuric solution having predetermined sulfuric acid and aluminum ion concentrations at a predetermined temperature for 1 to 180 seconds, and (4) an electrolytic surface-roughening step of processing the desmutted aluminum plate in an aqueous nitric acid solution with an alternating current being applied thereto. The invention enables stable and inexpensive production of planographic printing plate supports even from regenerated aluminum.
