A printer includes an array of rollers, an array of printing elements, and a positioning structure. The array of rollers is arranged in a first arc configuration to rollingly support a media web in a first orientation. The array of printing elements is arranged in a second arc configuration along the first orientation and movable relative to the array of rollers to selectively modify a space there between. Each respective printing element is aligned directly above one of the respective rollers to define a printing unit. A positioning structure is configured to releasably secure each printing unit at one position of a plurality of positions along the respective first and second arc configurations.

Various embodiments and methods relating to moving a printed upon web along bowed segments of a web path through at least three consecutive turns in a same direction are disclosed.

Media treatment web flow path

A web flow path extends in a first direction opposite a print head and in a second opposite direction from the print head to a dryer.

Web flow path

A side shift mechanism for a deck of a printing press enables a roll, for example, a plate roll and/or an anilox roll, to be shifted axially so that one end of the roll extends out of the frame of the press. The extended roll or a sleeve on the roll is thereby made accessible for easy exchange. After the roll or sleeve is exchanged, the roll is shifted back to its original position.
