AN IMPROVED REGISTER CONTROL SYSTEM Abstract Of The Disclosure Apparatus is disclosed for controlling the lateral position and the circumferential or rotational phase position of controllable cylinders in a printing press for the purpose of controlling the registration of the printing of a web. The apparatus includes a drive mechanism for moving each controlled cylinder axially in either direction as well as a drive mechanism for moving the cylinder to advance or retard the rotational phase position thereof, a sensing means for sensing the axial and rotational phase positions, a master control with selector switched for selecting a cylinder to be controlled, directional switches for implementing movement in opposite axial directions as well as opposite rotational phase position directions, and a keyboard for entering the amount of movement that the cylinder is to be changed. The master control also includes a display which displays the amount of movement that is to be implemented. The apparatus includes a secondary control also having a keypad which includes switches indicating the direction of movement and these switches move the cylinder in the appropriate direction by a predetermined amount for each actuation thereof or at a predetermined rate upon continued actuation thereof. Each of the secondary controls is dedicated to a preselected cylinder which facilitates easy association and control of that cylinder by an operator.
