1. A method performed by at least one computing device for controlling a printing process for printing a decorative target image onto a substrate, comprising:
providing the decorative target image to be printed in the printing process by at least one decorative parameter data set;
simulating the printing process in a simulation step based on the decorative parameter data set, at least one printing process parameter data set and stored historical printing data sets such that a digital decorative image is generated;
verifying the generated digital decorative image based on the decorative target image to be printed and at least one verification criterion,
wherein the verifying of the generated digital decorative image comprises comparing the digital decorative image generated by the simulation step and the decorative target image, and
wherein the at least one verification criterion is a comparison criterion that specifies at least a predetermined minimum optical similarity measure between the digital decorative image generated by the simulation step and the decorative target image; and
outputting the printing process parameter data set used in the simulation step to conduct the printing process, if the verification criterion is met.
