Abstract:
A process for correcting geometric errors in the transfer of information to a printing stock, comprising the steps of:creating at least one device-dependent matrix using a device-independent description of the information to be printed;supplying the at least one device-dependent matrix to a matrix manipulation device;transforming said at least one device-dependent matrix to at least one transformed matrix such that a size of said at least one transformed matrix is the same as a size of the at least one device-dependent matrix by subjecting the elements of the at least one device-dependent matrix to a correction transformation using a correction function depending on previously generated parameter values, wherein the parameter values are generated using measurement technology and the correction function comprises one of inserting, removing, shifting, and changing an individual element of the at least one device-dependent matrix; andsupplying the at least one transformed matrix to at least one digital imaging unit.
