Abstract: The invention relates to a method for profiling a print medium for use in a printing system. The print medium is received in an input holder and a plurality of test jobs is received in a test job receiver. For each test job a uniquely determined combination of at least a first printing system parameter of print speed of the printing system and a second printing system parameter of coverage of the marking material is intended to be prepared by a print controller. The printing system registers a test result of each test job. The print controller creates a two-dimensional media print mode table of media print modes for the print medium to be profiled based on the test results of the test jobs for the print medium. When a print job arrives intended to be printed on the profiled medium, a media print mode is selected from the two-dimensional media print mode table.
