摘要： A roll for metal rolling has a roughened surface formed by an electrolytic treatment in an electrolytic solution while using the roll as an anode. When the roll is used to emboss an aluminum plate, it is possible to obtain an aluminum plate with an uneven structure having regulated positions of levels of peaks and a larger number of the peaks. A presensitized plate formed by use of the aluminum plate as a support has excellent printing performances particularly in the number of printed sheets and sensitivity.

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.
