A method for printing on a printing material web by using a rotary offset printing machine, wherein the rotary offset printing machine includes at least one printing unit having at least two plate cylinders, comprising the steps of:
- feeding the printing material web into and through the at least one printing unit, wherein the printing material web has a first side and a second side and wherein the printing material web is treated to reduce or avoid an inherent relative movement to itself;
- and
- printing on the first side of the printing material web by a blanket cylinder on which respective images from the at least two plate cylinders have been transferred onto, wherein the at least two plate cylinders are arranged relative to each other with respect to their operation such that the images from the at least two plate cylinders are transferred to an identical position on the blanket cylinder.
A rotary offset printing machine for printing on a printing material web, comprising:
- at least one printing unit, including:
- at least two plate cylinders;
- at least one blanket cylinder;
- at least one impression cylinder arranged opposite to the at least one blanket cylinder;
- and
- at least one inking unit corresponding to one of the at least two plate cylinders;
- wherein the at least two plate cylinders are arranged relative to each other with respect to their operation such that images from the at least two plate cylinders are transferrable to an identical position on the blanket cylinder;
- and wherein the at least one printing unit is configured to print on the printing material web which is treated to reduce or avoid an inherent relative movement to itself.
