Abstract
This invention relates to an offset printing apparatus, which comprises a frame and a removable cassette comprising a plate cylinder and a blanket cylinder, with parallel transverse axes, tangential to each other and adapted to be engaged in the frame of the apparatus so that the plate cylinder is in contact, under pressure, with each inking roller with a predetermined touch, i.e. a predetermined crushing of the peripheral layer, of supple material, of the inking roller. This touch is determined by a first bearing element or touch way, associated with each bearing of an inking roller and, on each removable cassette, a second bearing element or touch way. In order automatically to obtain the correct touch when a cassette is changed, the second touch way of the cassette is constituted by a fixed disc bearing a covering, forming a coating of thickness equal to that of the covering associated with the plate.
