Method for exposure of flexo printing plates

In order to improve a method for producing a structure of polymerisation picture points in a light-sensitive layer of printing plates, in particular flexo-printing plates, as an image of picture data composed from a matrix of picture points, by way of structured exposure with a light source, to the extent that an improved tonal range of the print picture is achieved and simultaneously that the manufacturing time is reduced, it is suggested for each polymerisation picture point to be produced by an individual exposure sequence which on the one hand is selected in dependence on the surface density of the polymerisation picture points to be set at the location (A, B, C, D) of the polymerisation picture point and one the other hand in dependence on the picture data.
