Method for color correcting a digital printer

A method for color correcting a digital printer over a printing width of the digital printer, wherein the digital printer is provided for outputting a specified digital image, wherein the method comprises the steps of:

• a) providing the specified digital image, wherein the digital image comprises at least one color channel pattern, wherein each color channel pattern is associated with a print color channel of the digital printer;
• b) determining at least one test color of the specified digital image;
• c) creating a digital test pattern, wherein the digital test pattern is provided with at least one single-colored test stripe intended to be printed over the printing width of the digital printer, wherein each single-colored test stripe is defined by a print density of at least one print color channel of the digital printer according to the following steps:
• i) determining a print density of at least one print color channel of the digital printer intended for printing the test color;
• and
• ii) specifying the print density determined in step i) as the print density of the single-colored test stripe;
• d) printing the digital test pattern by use of the digital printer;
• e) detecting the color values of the printed test image as a function of their position in the direction of the printing width by use of an optical color measuring device;
• f) creating correction data for the digital printer based on the detected color values;
• and
• g) applying the correction data to the digital printer and/or the specified digital image.
