Method of printing at least two print jobs on one printing machine

A method for printing at least two print jobs on one printing machine, which comprises the steps of:

• a) printing a first print job on the printing machine using a first combination of a printing fluid and a substrate, a specified international color consortium (ICC) profile, and a first machine setting of the printing machine;
• b) preparing a printing operation for a second print job involving a change of the printing fluid and/or of the substrate to a second combination of the printing fluid and the substrate, wherein step b) includes the sub steps of:
• b1) printing a test print on the printing machine, the test print including a plurality of test fields, using the second combination of the printing fluid and the substrate, the specified ICC profile, and the first machine setting;
• b2) recording all or at least a selection of the test fields of the test print using a recording device;
• b3) computationally determining and saving a quality value on a basis of the test fields recorded;
• b4) computationally determining and saving at least one 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 at least one adjustment value or selectively keeping the first printing machine setting, and making a choice of the printing machine setting in dependence on the quality value;
• and
• c) printing the second print job on the printing machine using the second combination of the printing fluid and the substrate, the specified ICC profile, and in accordance with the choice made in step b), the first machine setting or the second machine setting.
