1. A method for printing a print job with a printing machine, the method comprising:
a) determining a master setting for the printing machine by:
a1) providing a substrate as a master substrate;
a2) printing a first test print including a multiplicity of test fields, with the printing machine, and using a first combination of a printing fluid and the master substrate;
a3) recording all or at least a selection of the test fields of the first test print by using a recording device; and
a4) computationally determining and storing at least one first setting value for a first machine setting of the printing machine as the master setting;
or
a1) providing a substrate as a master substrate; and
a4′) computationally determining and storing at least one first setting value for a first machine setting of the printing machine as a master setting and for a first combination of a printing fluid and the master substrate, and carrying out the computational determination based on a computer-implemented mathematical model including a mathematical representation of the printing machine, of the printing fluid and of the substrate, or based on an artificial intelligence trained with stored data relating to at least one of printing machines or substrates;
b) preparing printing of a print job with the printing machine by:
b1) changing the substrate to a second combination of printing fluid and substrate;
b2) printing a second test print including a multiplicity of test fields, with the printing machine, and using the second combination of printing fluid and substrate and the master setting;
b3) recording all or at least a selection of the test fields of the second test print by using a recording device; and
b4) computationally determining and storing at least one second setting value for a second machine setting, and defining the second setting value as a value relative to the master setting; and
c) printing the print job with the printing machine, and using the second combination of printing fluid and substrate and the second machine setting.
