What does SwiftVerify measure?
For linear symbols, ex: Code 128, SwiftVerify will use all of the measurements defined in ISO/IEC 15416. These grades include: the ability to decode following the reference decode algorithm, symbol contrast, minimum reflectance, minimum edge contrast, modulation, defects in printing and the decodability of the symbol. SwiftVerify will also measure and output the following: the wide to narrow ratio, minimum and maximum reflectance, print contrast signal (PCS), average bar gain or loss, average narrow element width, and the size of the quiet zone.
For multi-row bar code symbols, ex: MicroPDF417, SwiftVerify uses the measurements defined in ISO/IEC 15415. These grades include: the analysis of the scan reflectance profile, codeword yield, unused error correction and codeword print quality. SwiftVerify will also measure and output the following: the number of rows and columns in the symbol, the number of data code words, the number of error correction codewords and the value of each code word in the symbol.
For postal symbologies, ex: POSTNET, SwiftVerify uses the MERLIN guidelines published by the United States Postal Service. The grades include: the width and height of each bar, the position of each bar, baseline shift, bar tilt, pattern skew, bar pitch, bar code clearance, connected bars and extraneous ink.
