Lithographic printing plates having a smooth, shiny surface |
| abstract |
The present invention relates to supports for lithographic printing plates and to a process for producing the same. In particular, the invention relates to aluminum plates having an electrochemically grained and anodized surface which is has a smooth, shiny surface and hence greater image contrast when a lithographic image is formed thereon. The surface has a substantially uniform surface topography comprising peaks and valleys and surface roughness parameters wherein Ra ranges from about 0.10 to about 0.50 microns, Rz ranges from about 0.00 to about 5.00 microns, Rt ranges from about 0.00 to about 6.00 microns and Rp ranges from about 0.00 to about 4.00 microns. The surface preferably has tristimulus color coordinate values wherein L ranges from about 35.00 to about 75.00, a ranges from about -4.00 to about +4.00 and b ranges from about -4.00 to about +4.00. |
