ABSTRACT:
A method and the means for practicing the method is disclosed for verifying the encodation accuracy of a Universal Product Code master symbol that is to be printed on a consumer product carton or the like. The means for practicing the method consists of an Encodation Verifier which is preferably printed on a piece of film or glass and which includes 113 numbered light spaces and dark bars which represent the total modules of the code symbol, and an Encodation Worksheet form on which information obtained form comparing the Encodation Verifier with the symbol to be verified, is entered. Thus, the method for verifying the symbol encodation comprises a graphic comparison of the Encodation Verifier with the symbol to be verified. The method is preferably practiced visually under low power magnification but could be done mechanically with an optical device such as a reader/printer machine.
