Quality control method for planographic printing plate |
摘要 |
<p>An image evaluation method of the planographic printing plate comprises the steps of (A) producing a standard developer-treated planographic printing plate by preparing a planographic printing plate precursor comprising a substrate and a photosensitive layer, which includes an aqueous alkaline solution-soluble resin and a compound that absorbs light and generates heat, on the substrate, exposing the planographic printing plate precursor under a condition that forms a checkerboard image of rectangles having one side that is 5 to 50 mu m in length, and then developing the image with a standard developer; (B) producing a subject developer-treated planographic printing plate in the same manner as the above-mentioned step (A) except the development is carried out with a subject developer to be evaluated; and (C) comparing the above-mentioned checkerboard images resulted from the standard developer-treated planographic printing plate, with that resulted from the subject developer-treated planographic printing plate.</p> |
