Abstract:
A method for fabricating a plurality of encoders on a sheet of polymer substrate, each of said plurality of encoders for use as a registration reference for a print head of a printer, each of said plurality of encoders having a plurality of registration markings aligned in a longitudinal direction, said method comprising the steps of:providing an optical imagesetter device having a curved surface rotatable about an axis of rotation for receiving the substrate and a controllable light source for directing light onto the substrate, said curved surface having an axis of curvature; providing the substrate onto the curved surfaced on which the plurality of encoders are to be imprinted; and aligned and projecting an image of the plurality of encoders onto the substrate with the longitudinal axes of the plurality of encoders being substantially parallel, the longitudinal axis of each of the plurality of encoders being offset relative to the axis of rotation by a predetermined angle that is inclusive of 0.1 degree to 45 degrees.
