Consecutive printing of different print jobs which require alternating substrate thickness on an In-
Line-Primer (ILP) powered Digital Printing Press requires insertion of multiple non-productive
(null) cycles. This is required to allow ILP to adjust its hardware (gravure rollers, gaps, etc.) such
that priming of the substrate will be optimal prior to printing. The method proposed, allows
printing of such jobs seamlessly, minimizing the number of non-productive cycles to a minimum of
(1-2) vs. ( >10) prior to the old method.
