ABSTRACT:
Methods of bonding a printing plate on a base film and an apparatus therefor are disclosed. The apparatus includes a pair of support mechanisms, one of which is horizontally located and the other of which is disposed at a right angle with respect to the horizontal one. A strip of paper is reeved around the horizontal support mechanism, while a strip of film is reeved around the vertical one. A plotter is provided above and in conjunction with the horizontal support mechanism for marking the location on which to place a printing plate, on the paper reeved around the horizontal support mechanism. A half mirror is disposed in close proximity to both of said horizontal and vertical support mechanisms for projecting the location marked on the paper onto the film reeved around the vertical support mechanism. Using a lifter, the operator looks down the half mirror to view the location of a printing plate as projected onto the film, and bonds the printing plate to the base film in that projected location.
