Abstract
A method prints a printed image containing at least one machine-readable optical code. During a color space transformation, the digital data of the code within the printed image are transformed according to a different method to the remainder of the printed image, with the number of printing colors of the code being reduced during the transformation.

A method for printing, by way of a printing machine, a printed image containing at least one machine-readable optical code, in which digital print data for the printed image are provided, the digital print data for the printed image containing the digital print data for the at least one machine-readable optical code and the digital print data for a remaining printed image, which comprises the steps of:
- subjecting the digital print data for the printed image to a color transformation including a transformation of colors in the printed image to printing colors of the printing machine, during the color transformation of the digital print data for the printed image, the digital print data for the at least one machine-readable optical code are transformed using a different method to the digital print data for the remaining printed image, and a number of the printing colors for the at least one machine-readable optical code are reduced in the digital print data for the at least one machine-readable optical code;
- and
- transmitting the digital print data for the printed image subjected to the color transformation to the printing machine and being used to print the printed image using the printing machine.
