1. A method for a printing system for processing a print job, the printing system having a print controller for controlling a printing process and a print head for depositing marking material on a recording medium, the print job comprising print data and having a plurality of print job settings specifying a print action on the recording medium, at least one finishing action on the recording medium and a book, the method comprising the steps of:
receiving the print job comprising the print data and the plurality of print job settings,
automatically establishing a first area being a margin extending about an edge of the recording medium, a second area inside the first area and at least one area of the second area that is made not visible during the at least one finishing action and in a spine area of the book,
determining at least one digital object comprising an image quality control mark and consisting of image pixels having image pixel values to be retrieved from memory of the print controller, which image quality control mark is intended to be used for checking and monitoring at least one characterization of the book and is printed inside the second area and is stored in memory separately from the print data of the print job,
determining pixel positions of image pixels of the print data which, when printed by means of the print action, correspond to a location in the established at least one area of the recording medium,
creating first print instructions for depositing marking material on the recording medium according to the print action in order to print the print data,
creating second print instructions for depositing marking material on the recording medium at the determined pixel positions according to the image pixel values of the at least one digital object, and
printing the print data and the image pixels of the at least one digital object on a same sheet of recording medium according to the first and second print instructions.
