Abstract: Methods and systems for generating a secure copy of content associated with a non-fungible token (NFT) are disclosed. The system will receive a print request to print digital content that is associated with an NFT, access a blockchain to identify a current owner of the NFT, and generate a print job that with instructions to print the NFT content. If and only if the current owner of the NFT is the requesting entity, the system will print a unique authentication code with the digital content. The system will cause a print engine to print the digital content on a substrate or as a 3D object. In some embodiments, the system may be included in a print device that includes the print engine. Other aspects include a system that verifies whether a printed copy of content is an authorized copy, using the unique authentication code and the NFT described above.

Abstract: What is disclosed is an object holder for securely retaining a 3-dimensional object while it is being printed in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a frame configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object. A flexible belt is positioned around an inside of the frame to form a circle. One end of the belt is fixed to the frame. An opposite end of the belt passes through an opening in a side of the frame. Pulling the belt through the opening tightens the belt encircled around the object in the frame. A lock prevents the belt from loosening after it has been pulled tight.

Abstract: A sheet processing system for automated sheet adjustment includes a sensor system which captures at least a first image of a sheet of print media as the sheet is conveyed on a main transport path between a print media supply module and a marking device of an image rendering module. A control module computes a lateral error for the sheet, based on the captured at least first image, and computes an adjustment based on the computed lateral error. A sheet transport path adjustment mechanism translates a first portion of the main transport path relative to a second portion of the main transport path, based on the computed adjustment.

Abstract: A system and method evaluate defects in printed images. A target image, which has been captured of a printed image, is processed to identify defects, where present, which do not occur in a source image from which the printed image was generated. A trained classification model predicts a defect class for respective regions of the target image, each of the defect classes being drawn from a predefined set of defect classes. For at least one of the identified defects, a measure of severity of the defect is determined, such as a size of the defect. A decision on the acceptability of the printed image is made, based on the measure of severity of the at least one defect and the predicted defect class of a respective one of the regions in which the defect occurs.

Abstract: An apparatus includes one or more layers of material printed by a three-dimensional (3D) printer. The one or more layers cool and solidify to form an object after being printed by the 3D printer. At least one of the one or more layers includes greater than 50% metal. The apparatus also includes a first temperature sensor in contact with the object. The first temperature sensor measures the temperature of the material while the object is being printed by the 3D printer, after the object has been printed by the 3D printer, or both.

Abstract: A media handling assembly contains a transport path for driving a document sheet downstream in a process direction. A first side edge extends lengthwise along the process direction. A registration guide edge extends lengthwise along the process direction and is situated opposite the first side edge. The media handling assembly includes at least one nozzle that is arranged proximate the first side edge. The at least one nozzle selectively discharges an airstream transverse the process direction towards the registration guide edge. The airstream drives the sheet against the registration edge guide for side registering and deskewing of the sheet.

Abstract: A process for thermoforming a circuit onto a three-dimensional part comprises applying electrically conductive lines on a substrate to form a flexible circuit. The flexible circuit is heated to a temperature sufficient to thermoform the substrate into a shape that conforms to said three-dimensional part and attached to the three-dimensional part.
