Procedure for Controlling Printing Quality

The invention concerns a procedure for controlling printing quality, wherein the digital presentation of the page original is utilized. As taught by the invention, prior to printing a plurality of measuring points are specified from the digital presentation of the page original on the basis of given initial data. The initial data for the measuring points are set so that at least two measuring points are locating points on the basis of which the other measuring points can be located. The other initial data are set according to what one desires to measure on the printed page. Thereafter, the locating points and other specified measuring points are sought in the digital presentation of the page original; and the measuring point data are entered in the printing quality measuring unit. The results of measurement from the measuring points are compared with the measuring point data from the digital presentation of the page original, or the objective values, and the results of comparison are used to adjust the printing machine.Patent family as of 5.5.2022AU199465399 A119941121AU1994006539919940426DE69413221 D119981015DE19946013221T19940426DE69413221 T219990506DE19946013221T19940426EP0699132 A119960306EP1994091313019940426EP0699132 B119980909EP1994091313019940426FI931876 A19941027FI1993000187619930426FI931876 A019930426FI1993000187619930426FI95888 B19951229FI1993000187619930426FI95888 C19960410FI1993000187619930426US5774635 A19980630US1995055347619951023WO9425278 A119941110WO1994FI001601994042
