Abstract
A duplex color web press, wherein each section, which prints both faces of the web with any one ink type and color, is configured with a single printing cylinder and, in the case of a digitally recording press, with a single recording head. The single printing cylinder carries the inking versions of both the recto and verso images around its circumference and the web is routed through two printing stations, both associated with the single printing cylinder, so that one of its faces is imprinted in one station and the other face--in the other station. The resultant print on each face is alternating recto and verso images, such that a recto image on one face is in the back of a verso image on the other face, and vice versa.
