    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.
