REVERSIBLE COLOR DECK FOR ROTARY PRINTING PRESSES Abstract of the Disclosure A reversible color deck apparatus for rotary printing presses for permitting a printer to selectively print a plurality of colors on one side or the other of a paper web. The apparatus includes a plurality of image delivery rolls or cylinders disposed in spaced relation. A pair of blanket rolls or cylinders are disposed within the space separating the image delivery rolls and are supported at their ends by eccentric sleeve elements. These sleeve elements are operatively interconnected by control linkage which, in turn, is connected to an actuating member for effecting simultaneous movement of the axes of rotation of the blanket rolls in the same directions. Via a neutral or throw off position, the axes of rotation of the blanket rolls can be moved to two different positions which permit the printing of a plurality of colors on that side of the web corresponding to the particular position to which the blanket rolls were selected to be moved.
