Laser or camera-based systems are used for pharmacode control in the production of pharmaceutical equipment. These systems segment thick and thin lines and then convert these lines into numerical values using binary arithmetic. Standards should be considered when creating a combination of thick and thin lines for packaging. Increasing or reducing lines by distorting the proportion will cause vision inspection algorithms to produce incorrect results. Moreover, the close design of the area on which the pharmacode is applied with the OCR/OCV areas will allow both reading operations to be performed together.

In conclusion, the same pharmacodes must be applied to each form of the drug, such as carton, aluminium foil, prospectus, and label in order to control that the packaging consists of the correct units. The product with a false pharmacode must be removed from the line with the rejection mechanism by controlling the pharmacode during the production process. In the case of reading pharmacodes with different values in the production line, in-process control must be done and the root cause of the error should be investigated.

As VISIOTT TPS, we have solutions that perform pharmacode verification in the hardware that we have produced for traceability projects. You can contact us for more detailed information.
