Abstract: A method for printing defect detection includes processing and analyzing a difference image obtained by comparing an image scanned with a verifier to a reference image. The detected defects are grouped, and the grouping is refined. Confidence level values are then assigned to the refined groups, and analysis is performed to determine if one or more servicing actions should be taken.

Abstract: A method for encoding a Radio Frequency Identification (RFID) inlay is described. The method includes causing, by a processor, a media to travel along a media path in an RFID printer. The media includes a plurality of labels. Each label of the plurality of labels comprises an RFID inlay. The method also includes determining a real-time position of a first label while the media travels along the media path based on an input signal received from a media sensor. The first label includes a first corresponding RFID inlay. Further, the method includes causing an RFID control system to initiate encoding of the first corresponding RFID inlay, and to rotate and continue encoding of the first corresponding RFID inlay until the first corresponding RFID inlay is successfully encoded. The RFID coupler is rotated based on the real-time position of the first label.

Abstract: Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printed image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printed image according to verification requirements.
