ABSTRACT:
A multicolor rotogravure printing system comprising a train of as many monochromatic printing units as the number of the colors required, each printing unit comprising an upper structure including an impression roll and a lower structure including a plate cylinder. These upper and lower structures are adapted to connect and disconnect from each other, and the upper structures are fixed to and suspended from a main frame. Each lower structure has a moving means, thus making it easy to change a used lower structure for a fresh one, and at the same time to perform necessary adjustment of those parts of the printing unit which are made accessible by removal of the lower structure. Also, the length of idle time in printing operation is appreciably reduced.
