Method for controlling a decorative printing process

A decor printing system, comprising:

• at least one receiving module configured to provide a decorative target image to be printed in a printing process by at least one decorative parameter data set;
• at least one simulation module configured to simulate the printing process in a simulation step based on the provided 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;
• at least one verification module configured to verify the created digital decorative image based on the decorative 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
• at least one output module configured to output the printing process parameter data set used in the simulation step if the verification criterion is met.
