Abstract
Abstract An apparatus, method and system for verifying the accuracy of a sample of printed or other reproduced material. In the apparatus, a base is provided having a support surface for securing the reproduced sample to said surface, with a transparent support means slidably lying contiguous to the support surface. A transparent master symbol for verifying the accuracy of the reproduced material is secured to the underside of the support means so that the master symbol and reproduced sample are contiguous. Preferably, the image on said transparent master symbol is interrupted to provide open spaces to facilitate visual comparison with the reproduced sample. In operation, the sample is aligned with the master symbol to verify its accuracy. In the event that a portion of the reproduced sample and master symbol are not in alignment, the master may be moved to align said portion and the movement can be measured to determine the error in reproducing the sample.
