平版印刷版用アルミニウム支持体

The surface of the aluminum support for a lithographic printing plate needs a strong adherence with a photo or thermally sensitive layer to become an image area. However, it needs to be removed easily from the sensitive layer to become a non-image area. Furthermore, it is necessary to prevent the scumming ink from adhering to the surface of the aluminum support of the lithographic printing plate during printing. Therefore, it is necessary that the surface configuration of the aluminum support for the lithographic printing plate should be designed well for the surface shape from 10 microns order to a submicron order, and should have a less local deep part but enough roughness. The development of the surface configuration analysis methods make it possible to understand the surface configuration as the property values, and to design good printing plates based on the property values.
