There are 4 types of codes:
Scantrust Secure Codes (Non-Serialized): codes containing a single QR and single SG printed a large number of times. This means NO code within that work order is unique. This type of code is typically printed using analog printers (e.g. offset, flexo-gravure, rotogravure).
Scantrust Secure Codes (Serialized): each individual code containing a unique SG and a unique QR is printed exactly once with no two codes being the same. It is common practice for a number of extra codes to be provided to account for print run preparation, testing, and waste during the print process. Digital printers are used to create high numbers of these unique individual codes (e.g. inkjet, HP Indigo, etc). The main difference to Hybrid Secure Codes is the printing technique.
Hybrid Secure Codes (always serialized, otherwise hybrid printing would not be required): this is a combination of serialized QR codes printed in digital and an associated single SG printed in plate technology nearby the QR code, either inside or directly below the QR code. Typically the hybrid code printing process is used in environments where the QR code is printed AFTER the SG has been printed in the first print run. In some cases of hybrid printing, the secure graphic is printed below the QR code to give maximum flexibility to the serialized printer to compensate for any horizontal or vertical shifting when printing the QR code. However this generally increases the difficulty for the user to scan the secure graphic, so this is to be avoided if possible. The main difference to Serialized Secure Codes is the printing technique.
Scantrust Identifiers “SID”: Are serialized Scantrust without a Secure Graphic. They are used when the brand focus in predominantly on Consumer Engagement and/or Track & Trace, but not on Anti-Counterfeiting.
