Method and apparatus for setting a predetermined, by a pair of full-tone density / raster point change in defined in the case of a printing process may autotypical

摘要

the invention concerns a method and a device for setting a value pair volltondichte / rasterpunktu00e4nderung defined druckstandards a autotypisch working mehrfarbendruckmaschine.thus as early as possible during set up of the printing press for a new print job can be determined whether the druckstandard by mere activity of farbzonen - actuators is attainable, densitometrisch measured wertpaare volltondichte / rasterpu nktu00e4nderung with the help of the former.druckvorgu00e4ngen received similar correlations between the volltondichten and rasterpunktu00e4nderungen for conformity with the druckstandard studied.in the absence of conformity, the printing machine off and change relevant druckparameter such a change to the current, between the volltondichte and rasterpunktu00e4nderung existing dependence found that resumption of the druckvorg angs a conformity with the druckstandard arises.if necessary, these steps several times (fig. 1).
