Abstract
A process corrects geometric errors in the transfer of information without mechanical intervention on the printing form, to compensate for the errors that occur and thus attain optimized print quality prior to imaging. The corrections are visually indiscernible, so that the artifacts created in the printed result by the corrections do not stand out in the image. A device-independent description of the page information to be printed is converted by a Raster Imaging Process into at least one device-dependent digital matrix. Each matrix with m rows and n columns contains the information for a certain color to be printed. After the individual matrices are produced, they are supplied to a matrix manipulation device, which subjects each matrix to a correction transformation using specific parameters. After the matrices are adjusted, they are supplied by a matrix transfer device to the digital imaging devices in the printing mechanisms.
