Abstract
The printing plate comprises a rolled and embossed aluminium support whose surface has a coarse structure of pits, on which a fine structure of indents produced by electrochemical roughening is superimposed. The indents have a diameter of from 0.1 to 6 μm, and the average roughness Ra of the surface of the embossed aluminium support is in the range from 0.63 to 0.82 μm.
Claims16
Printing plate having a radiation-sensitive recording layer on a rolled and embossed aluminium support which has a surface structure having pits which have an average diameter of from 10 to 60 μm, preferably from 20 to 24 μm, characterized in that a fine structure of indents having indent diameters in the range from 0.1 to 6 μm produced by electrochemical roughening is superimposed on this surface structure.
