A method for setting up and carrying out a print job on an inkjet printing machine having print heads and a thermal dryer includes printing onto a substrate using water-based black and chromatic inks. First test prints of a first test chart with different area coverage test patches are generated on the substrate using black ink, thermally drying the first test prints at different temperatures and evaluating dried first test prints to determine a dryer operating temperature during the print job. A second test print of a second test chart with different ink amount test patches is generated on the substrate using chromatic inks, thermally drying the second test print at the temperature, and evaluating the dried second test print to determine a total ink amount for operating the print heads during the print job. The machine receives temperature and total ink amount and prints the print job.
