Pharmacode

Pharmacode, or Laetus Pharmacode, is a symbology used to match inserts, outserts, product labels, and cartons on production lines to prevent mislabeling of products. Pharmacode uses up to 12 bars, each wide or narrow, in order to encode up to 4096 possible unique combinations. Pharmacode does not use any start or stop characters and is not bidirectional. Therefore, the “value” encoded in Pharmacode will vary with the direction of reading. Webscan verifiers report the encoded value for both reading directions.

Grading the Quality of Pharmacode Symbols

All Webscan verifiers can decode and grade the quality of Pharmacode, but since there is no published standard for grading, our grading system is based on our judgement of what the grading would be if there were an ISO standard. For example, symbol contrast and modulation is clearly graded just as any other linear symbology according to ISO/IEC 15416. The only missing definition is for the parameter called decodability which evaluates the accuracy of the widths of the bars and spaces. The normal method for measure decodability is to determine the threshold between wide and narrow element widths and then grade the variability between the proper size and the threshold width. That is how Webscan Pharmacode checkers grade decodability for Pharmacode quality verification.

Webscan Pharmacode verifiers also measure typical traditional measurements such as bar width growth, MRD (minimum reflectance difference), and PCS (print contrast signal).
