A printing system comprises a transport apparatus adapted to transport a flexible web along a process direction and first and second individually controllable ink jet imager units offset from one another along the process direction. Each of the first imager unit and the second imager unit includes a first portion operable to print on a first portion of the web and a second portion operable to print on the second portion of the web wherein each of the first portion and second portion of the first and second imager units is stationary along the process direction and the lateral direction.

According to examples, an apparatus may include a first feed element and a second feed element, in which a web is to be fed to the first feed element and from the first feed element to the second feed element. The apparatus may also include a controller that may determine whether the web exiting the second feed element is shifted from an intended position and based on a determination that the web is shifted from the intended position, cause the first feed element to be moved laterally a first distance and the second feed element to be moved laterally a second distance to compensate for the shift in the web exiting the second feed element.

Apparatus for manufacturing a two-sided product with an integrated device on a web of material, including: a first rotary micro scale structure formation unit for having a first structure for forming a first microscale structure on one side of a portion of web; a second rotary microscale structure formation unit having a second structure for forming a second micro scale structure on second side of the portion of the web; the first and second micro scale structures and the portion of the web between the first and second microscale structures together forming the integrated device; and a web feed system for feeding the web of material between the first and second rotary microscale structure formation units.

A method for correcting a measurement value of a reference mark on a material web is disclosed. A controller, a machine, a computer program and a computer program product can perform a correction of this type. To improve determination of the position of a reference mark on a material web, a machine in which the material web is moved in a conveying direction has at least one tool that functions in a non-positive locking manner, a second tool that functions in a non-positive locking manner and is located downstream of the first tool in the conveying direction, and a sensor that is located between the two tools. A measurement error in the sensor which arises as a result of an adjustment of the second tool is determined at least approximately at least via parameter values of the second tool. The measurement value is corrected by the measurement error.

An arrangement for a corrugator for producing corrugated cardboard comprises a material web delivery device for delivering a material web and an edge cutting device, which is arranged downstream of the material web delivery device in a transport direction of the material web and has at least one edge cutting apparatus for edge-cutting the material web, and a digital printing device, which is arranged downstream of the edge cutting device in the transport direction of the material web for printing on the material web.
