Printing system and method for reducing the visibility of gloss differentials having at least one computer-supported inline imaging unit assembly designed to measure specular light reflecting gloss differentials of printed ink. At least one smoothing roller assembly is operationally connected to at least one sheet transport assembly or a smoothing transport subassembly of the sheet transport assembly of the printing system. A smoothing roller assembly is designed to roll at least partly the length and width of at least one printed side of at least one printed sheet disposed along the transport subassembly, pressure generated by the smoothing roller assembly configured to reduce detected gloss differentials from printed ink. At least the outer surface of the at least one smoothing roller assembly is substantially at least one or more of metal and polyurethane.

System and method to reduce the visibility of gloss differentials on printed sheets

A processor identifies print defect locations where printing defects occur and a assigns different sensitivity values to different zones of a job image being prepared for printing by a printing engine. The processor changes the orientation of the job image to a revised orientation, relative to print media, to avoid locating one or more high-sensitivity zones of the job image in the print defect locations. The high-sensitivity zones are ones of the zones having a sensitivity value above a threshold sensitivity value. The printing engine prints the job image on the print media at the revised orientation.

Optimized printing defect compensation using automatic job image repositioning

A method of automatically displaying a predetermined set of print attributes of a print job, the method including receiving an image of a first printed sheet, the first printed sheet including one or more at least partial machine-readable codes, the one or more at least partial machine-readable codes encoded with data related to the predetermined set of print attributes, decoding the data from the one or more at least partial machine-readable codes, determining if the data includes all of the print attributes in the predetermined set of print attributes, and if the data includes all of the print attributes in the predetermined set of print attributes, displaying the data using augmented reality (AR) over the first printed sheet.

System and method for retrieving and displaying print attributes using augmented reality

An input/output of a system receives an electronic file comprising text. A processor of the system identifies keywords in the text. The processor correlates the keywords to music attributes and matches the music attributes to musical works. The processor determines computer network locations of the musical works. The processor also adds links to the network locations of the musical works to the electronic file to create a music-enhanced electronic file. The input/output outputs the music-enhanced electronic file that now contains the links to the musical works.

Adding musical works links to textual items

An inkjet printer detects vibrations within the printer and compensates for the detected vibrations by adjusting a gap between the printheads and the media transport. Additionally, the inkjet printer detects media sheet heights that may cause damage as they pass through the print zone of the printer and adjusts the gap to enable the media sheets to pass through the print zone without contacting the printheads. A method of operating an inkjet printer so configured is also disclosed.

System and method for compensating for vibrations in an inkjet printer

Techniques for operating a digital printer that includes a media transport and an electronic imager disposed in a path of the media transport are presented. The techniques include: receiving an electronic image of a media sheet obtained by the electronic imager; identifying, from the electronic image of the media sheet, a print-prohibited region of the media sheet; generating a mask representing the print-prohibited region of the media sheet; and electronically storing in electronic persistent memory, in association with an identification of a type of the media sheet, a template comprising information regarding the media sheet type, where the template includes an identification of the print-prohibited region represented by the mask.

Automatic identification of print-prohibited regions and template creation

A method of operating a printer iteratively performs printhead purges and test pattern analysis until either every printhead has a number of inoperative inkjets that is less than a predetermined threshold or a maximum number of iterations is reached. An error message is generated for each printhead having a number of inoperative inkjets that is greater than the predetermined threshold. The iterative performance of the printhead purges and test pattern analysis is performed automatically prior to the commencement of printing operations with the printer to remove subjective and time-consuming analysis by a printer operator.

A method of analyzing decurling settings for a print request including a plurality of sheets, the method including receiving a real image of a first portion of the plurality of sheets, receiving a first input, displaying one or more decurler settings, and displaying a first augmented image of a stack of the plurality of sheets.

A secure document printing and delivery management system includes one or more print delivery vehicles, each of which includes an onboard print device. When the system receives a print job from a requesting device, it will select a print delivery vehicle instruct the print delivery vehicle to navigate to a delivery location. Upon arrival at the delivery location, the system will detect and verify a security token presented by a recipient. In response to detecting and verifying the token, the system may print the document (if not already printed) and it will present the document to the recipient.

A system treats uneven surfaces of additive manufactured objects to improve the transparency and glossiness of the surfaces. The system operates an actuator to dip the additive manufactured object into a bath of fluid material that is the same as the material used to form the uneven surface to smooth the surface of the object and operates a sprayer to apply another fluid material to a surface of the object that is identified as being rougher based on the object's geometric data. A heater is provided to dry non-UV curable material applied to the object and a source of UV radiation is provided to cure UV curable material applied to the object.

System for finishing the surface of three-dimensional (3D) objects formed by additive manufacturing systems

Various systems and methods maintain a print job of a user in a print queue and identify the user approaching a printing device using a user identification device operatively connected to the printing device. Such systems/methods alter the position of the print job within the print queue (e.g., to a higher priority position) or even begin printing the print job when the user identification device identifies the user approaching the printing device (i.e., before the user reaches the printing device). Systems and methods can also identify the urgency of the user using the user identification device. The amount that the print queue is altered can be based on the amount that the urgency of the user is elevated.

Modification of print queues based on user action and urgency

A system for producing three-dimensional objects forms fluid paths within the support structure to facilitate the removal of the support structure following manufacture of the object. The system includes a first ejector configured to eject a first material towards a platen to form an object, a second ejector configured to eject a second material towards the platen to form support for portions of the object, at least one portion of the support having a body with at least one fluid path that connects at least one opening in the body to at least one other opening in the body, and a fluid source that connects to the at least one fluid path of the support to enable fluid to flow through the at least one fluid path to remove at least an inner portion of the support from the object.

The voltage that is used for the encoding scheme is within a predetermined polarization regime of the printed memory device. Tuples of data can be read from memory cells of the printed memory using a decoding scheme.
