Abstract
A positioning jig for positioning copy material on the copybord of an offset print plate maker in order to make a photographic print plate bearing an accurately aligned image of the copy material. The positioning jig is provided with means for accurately positioning the copy material without the positioning stops casting an image which is photographically perceptible by the plate maker. The positioning jig includes a base having a substantially flat top facing surface defining a plurality of recessed positioning stops. Each of the positioning stops includes a pair of mutually perpendicular side walls having a relatively low height with respect to the length of the side walls. The base is formed by blasting a transparent acrylic sheet with an 80 grit aluminum oxide material so that the top facing surface is sufficiently irregular to permit light striking the surface to become randomly diffused in the base.
