    Abstract: A method of providing a parallel-sided, accurate-width linear land on the surface of a chemically-etchable homogeneous metallic member wherein the areas on each side of the land are to be etched downwardly in a manner and to a depth which inherently results in side-etching. The method utilizes a thin transparent backing sheet with an opaque scribbable surface thereon which is scribed to provide a thin line in the shape of the land to produce a first transparency. That scribed-transparency is placed in contact with an unexposed film sheet and the film sheet is exposed while relatively moving the first transparency and film sheet to produce a second transparency having an exposed area which is substantially identical in shape to the scribed line on the first transparency but having a wider dimension, the amount of relative movement being predetermined and a function of the relative side-etching which would result from achieving the desired etching depth below the surface of the metallic member. The planar surface on the metallic member is then coated with a light-hardenable sensitized coating material. Those areas of the coating corresponding with the exposed areas of the second transparency are exposed to light to harden those areas of the coating. After exposure, the unhardened coating material is removed from the surface, and the member is chemically etched.

    Abstract: Cooperating male and female cutting and creasing dies for blanking cartons and the like are produced by a chemical milling process and which process includes a final honing step which removes the sharp corners on the lands of the dies prior to installation thereby readying the dies for immediate full speed use on the machine.
