FLEXOGRAPHIC APPARATUS AND FILM-FORMING METHOD

METHOD AND APPARATUS FOR EXCHANGING A ROLL OF A PRINTING PRESS

A side shift mechanism for a deck of a printing press enables a roll, for example, a plate roll and/or an anilox roll, to be shifted axially so that one end of the roll extends out of the frame of the press. The extended roll or a sleeve on the roll is thereby made accessible for easy exchange. After the roll or sleeve is exchanged, the roll is shifted back to its original position.

METHOD AND APPARATUS FOR SAMPLING AND INSPECTING INK FOR A PRINTING PRESS

A sample of printing ink for a printing press is obtained using actual press components. An anilox roll for the press is supplied with ink and is rotated while the anilox roll is either mounted on the press or mounted off-line from the press. A printable substrate is printed with the ink either by pressing the substrate directly against the anilox roll or by pressing a transfer roll against the anilox roll and pressing the substrate against the transfer roll. The ink on the substrate is inspected, and any necessary changes to the ink are made before the press run is started.

DECK CONFIGURATION FOR A PRINTING PRESS

A deck for a printing press includes first and second rolls which are mounted for linear movement on a pair of spaced parallel rails. A rotatable ball screw moves the rolls along the rails. The axis of the screw substantially intersects the axes of the rolls.
