A printing method includes determining a master machine setting by using a master substrate, printing a first test print including test fields, and using a first combination of printing fluid and master substrate, recording test fields of the first test print, and computationally determining and storing a first setting value for a first machine setting as the master setting. Printing a print job is prepared by changing the substrate to a second combination of printing fluid and substrate, printing a second test print including test fields, and using the second combination of printing fluid, substrate and master setting, recording the test fields of the second test print, and computationally determining and storing a second setting value for a second machine setting, the second setting value defined relative to the master setting. The print job is printed by using the second combination of printing fluid, substrate and second machine setting.

Method for printing a print job with a printing machine

A method includes the steps of: a) printing a first print job on a printing machine using a printing fluid, a substrate, a specified ICC profile, and a first machine setting; b) preparing the printing operation of a second print job involving a change of the printing fluid and/or of the substrate; and c) printing the second print job using a second combination of printing fluid and substrate. Step b) includes: b1) printing a test print having a plurality of test fields; b2) recording the test fields; b3) computationally determining and saving a quality value based on the test fields; b4) determining and saving an adjustment value for a machine setting; and b5) selectively changing a printing machine setting from the first machine setting to a second machine setting using the adjustment value or keeping the first printing machine setting, and the making a choice based on a quality value.
