Analysis of the silver halide printing plates after printing process

One of the most important features in lithography is the stability of the printing plates during the printing process. It is highly influenced by the consistency and the wear of the photoactive and the aluminium oxide layers. In this paper the optical properties of the silver halide photoactive layer were observed by measuring coverage value on the printing plates before and after the printing process. The results have shown that the wear of silver halide layer is not significant but is visible after 80000 prints made. This fact leads to conclusion that this kind of printing plate enables high quality prints through the long printing run.
