Claim 0:
1. A method for profiling a print medium for use in a printing system, the printing system configured to print on profiled print media and comprising:
a print controller for controlling printing system parameters to be applied when printing on the print medium;
a print engine for printing marking material on the print medium;
an input holder for receiving the print medium in the printing system;
an output holder for receiving the print medium when printed by the print engine;
a test job receiver for digitally or analogue receiving a plurality of test jobs submitted to the printing system;
a paper path comprising a duplex loop for sending the print medium twice along the print engine; and
sensors along the paper path,
the method comprising the steps of:
a) receiving the print medium in the input holder;
b) digitally receiving the plurality of test jobs in the test job receiver, wherein for each test job of the plurality 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 the print controller;
c) for each test job:
c1) processing the test job according to the uniquely determined combination using the print medium to be profiled; and
c2) the printing system registering a test result of the test job wherein the test result is derived from sensor values registered by the sensors in the paper path of the printing system and measured during the processing of the test job; and

d) the print controller creating a two-dimensional media print mode table of media print modes for the print medium to be profiled based on the registered test results of the plurality of test jobs for the print medium, the two-dimensional media print mode table to be selected from when printing on the print medium, wherein each media print mode is uniquely determined by a uniquely determined combination from step b) and comprises an indication item of the test result corresponding to the uniquely determined combination.
