    摘要: A process for producing an aluminum support for a planographic printing plate, the process comprising the steps of: (a) preparing an aluminum plate; (b) disposing said aluminum plate in an aqueous acidic solution; and (c) electrochemically surface-roughening said aluminum plate using an alternating current, wherein a ratio QC/QA of a cathode-time quantity of electricity of said aluminum plate QC to an anode-time quantity of electricity of said aluminum plate QA is from 0.95 to 2.5. An aluminum support for a planographic printing plate formed by the process. A planographic printing master plate comprising at least a positive-type or negative-type light-sensitive layer on the aluminum support.

    摘要: A substrate for a planographic printing plate and a method of fabrication thereof. After a surface roughening treatment and before an anodizing treatment, an aluminum alloy plate to be used as the substrate is washed in an alkali solution, and then in an acidic solution. After surface-roughening, overlap points of Fe and Si macularly distributed at the surface of the aluminum alloy plate have a surface coverage of not more than 0.5%, and there are no more than 800 per 1 mm2 of overlap points which have sizes larger than 1.6null10null7 mm2. The planographic printing plate of the present invention has excellent printing capabilities in that, irrespective of printing conditions, soiling does not occur at a non-image portion of the planographic printing plate.

    摘要: A process and apparatus for conducting an electrically independent current through an anodized web to electro-deposit a coloring agent on the web. A preferred process includes the step of providing a continuous web of anodized aluminum; transferring with a charging plate a coloring current to the web with a charging plate in a first treatment cell over an area of the web sufficient to allow the current to pass through an anodic layer of the aluminum and flow through the web; and electro-depositing coloring agents on the web with the coloring current in a second treatment cell. Optionally, the web may be serially passed through additional treatment cells to apply a variety of different coloring currents to the web whereby the web may be colored with multiple coloring agents and consequently exhibit multiple colors and/or refractive properties.
