ABSTRACT:
In a process and apparatus for printing on flat individual articles such as CDs by means of offset printing, the surface to be printed upon and the offset printing cylinder which is rolled against the article are adjusted relative to each other to produce a pressure effect which is favorable to transfer of the print image on to the article in order to compensate for differences in thickness between the individual articles. When adjusting the printing cylinder and the surface to be printed upon relative to each other, the radial position of transfer surfaces at the periphery of the printing cylinder may, if necessary, be taken into account. In the absence of an article in the printing station, it is possible to provide a replacement article in the form of a web of material, on to which the print image intended for the missing article is transferred from the printing cylinder. The plate cylinders may also be adjusted relative to the offset printing cylinder in such a way as to permit adaptation to the radial position of the transfer surfaces at the periphery of the printing cylinder.
