Abstract: A method of printing using a press having first and second printing units and responsive to electronic data includes the steps of running the press to cause first and second printing units to produce first and second printed components, respectively, on a substrate, stopping the press and inspecting the first and second printed components to determine a degree of misregistration of the first printed component relative to the second printed component caused by substrate growth. Original electronic data representing an image to be printed by the press are modified in dependence upon the degree of misregistration. The press is subsequently operated in accordance with the modified electronic data to print the image with a reduced degree of misregistration.
