Abstract
An aligning method including steps of placing a printing plate on a transparent plate-carrier which is driven in vertical and horizontal directions; photographing the printing plate and a plate holder, to which the printing plate is to be attached, via a camera from below the plate-carrier; matching standard lines of the plate holder and printing plate with the cross lines of a monitor; lowering the plate holder until the plate holder comes into contact with the printing plate, then attaching the printing plate to the plate holder. The device for such method includes: a plate holder; a plate holder driver which drives the plate holder vertically and horizontally; a plate-carrier installed apart from printing position; a plate-carrier drive drives the plate-carrier in the vertical and horizontal directions; a camera installed below the plate-carrier so that the camera takes pictures of the standard lines of the plate holder and printing plate; and a monitor reproducing the image obtained by the camera. With such an arrangement, the standard lines of the plate holder and printing plate can easily be matched with the cross lines of the monitor, performing a accurate attachment of a printing plate to the print holder.
