The Contrast Symbol Grade cards are offered in Grades A,B,C,D,F (4,3,2,1,0) of contrast for use in testing bar code verifiers. Each symbol is individually calibrated to ANSI X3.182/ISO 15416 standards using a custom built microdensitometer. The images are precisely created in photo-emulsion. The reflectance of both the bars and the background are modified. Each card is individually serialized, major values are marked on the card, and all values are included in a written report.
