Abstract (en)

[origin: WO8907525A1] In line-by-line recording of films (15') for producing offset printing forms or in line-by-line illumination of offset printing plates from the recorded data, i.e. density values of a line, the adjustment values for the individual adjusting screws are obtained directly from the density values and stored or supplied directly to the printing machine (80). Before the adjustment values are supplied directly to the printing machine (80), density values are advantageously converted to the adjustment values by means of masks, which in relation to the printed area on the pages (50), and in relation to the register systems of the printing machine (80) and to the identification data of a page (50), contain the allocation of the adjustment values of the adjusting screws obtained from the density values of the page. The masks can preferably be produced by means of a PC (60) and the adjustment values temporarily stored or supplied directly via an interface to the adjustment control (70) of the printing machine (80).
