    摘要: A pin registration system uses a plurality of registration pins having different thickness heads to align an edge of a printing plate when mounting the plate to a drum of an imaging system. The registration pins are optionally adjustable along the longitudinal axis of the drum. The registration system avoids the requirement to punch holes or notches in a printing plate and does not require adjusting the thickness of a common registration pin. The registration system allows printing plates having different widths to be mounted without necessitating adjustments of the registration pins.

    摘要: A center justified pin registration system uses a plurality of pairs of registration pins having different thickness heads to align an edge of a printing plate when mounting the plate to a drum of an imaging system. The registration pins are optionally adjustable. The registration system avoids the requirement to punch holes or notches in a printing plate and does not require adjusting the thickness of a common registration pin. The registration system allows printing plates having different widths to be mounted without necessitating adjustments of the registration pins. An alternate embodiment employs a plurality of pairs of registration pins having uniform thickness heads.

    摘要: A media handling system is provided for an imaging system, such as an external drum platesetter. An edge clamp used to secure a printing plate onto a cylindrical media support surface of the external drum is movable about the drum surface to accommodate the use of different size plates. The edge clamp includes a clamping bar which is radially movable with respect to the media support surface to attach to the media support surface and capture an edge of the printing plate by employing vacuum hold down force.

    摘要: An apparatus and method for supporting and feeding printing plates in an imaging system. The apparatus includes a vacuum system for picking up an edge of a top printing plate from a stack of printing plates, and a peeling system including a pair of rotatable belts, a plurality of plate feed beams attached to, and extending between, the pair of rotatable belts, and a drive system for rotating the pair of rotatable belts to displace the plurality of plate feed beams between the top printing plate and an underlying printing plate in the stack of printing plates, thereby peeling the top printing plate from the stack of printing plates.

    摘要: An apparatus and method for picking a single printing plate from a stack of printing plates. The apparatus includes a plurality of suction cups, a peeler, a drive system for displacing the suction cups and the peeler against the surface of the top printing plate on the stack, a vacuum source for supplying a vacuum to the suction cups to secure the suction cups against the surface of the top printing plate, and a system for rotatably displacing the suction cups relative to the peeler to peel a portion of the top printing plate off of the stack. The center line of rotation of the displacing system is located at a contact point between the peeler and the surface of the top printing plate. This prevents any relative motion of the top printing plate against the next, underlying printing plate on the stack during the peeling operation.
