Description

Technical Field

[0001] This utility model relates to the field of positioning technology, specifically to a QR code positioning pad with variable data printing. Background Technology

[0002] In Variable Data Printing (VDP), the "positioning pad" for QR codes is an auxiliary structure whose core function is to improve the positioning accuracy and recognition stability of QR codes in dynamic printing environments, especially addressing issues such as QR code pattern differences caused by variable data, minor offsets during printing, or media deformation. A characteristic of VDP is that the content (including QR codes) of each printed product varies (e.g., personalized information, unique identifiers), and the QR code pattern changes with the data. In this case, the standard positioning structure of the QR code itself (such as the three corner positioning graphics of a QR code) may be difficult for recognition devices to quickly locate due to content differences or printing errors (e.g., positional offset, stretching, blurring). The positioning pad, by providing fixed, QR code-associated reference marks, helps the recognition system or automated equipment quickly locate the physical boundaries, angles, or center of the QR code, compensating for interference from printing variables (e.g., paper expansion and contraction, registration errors, uneven ink distribution), ensuring accurate reading of the QR code.

[0003] However, existing positioning pads are usually of fixed size, making them difficult to apply to QR code printing of various sizes. Therefore, a QR code positioning pad for variable data printing was invented. Utility Model Content
