20120162299 | Control System To Minimize Inadvertent Ink Jetting - A printer includes a web transport that is configured to transport a web of media along a transport path through the printer. Printheads in the printer are associated with web detectors that detect the presence or absence of the web opposite the printheads. A controller in the printer is operatively connected to the web detectors to alter operation of the printer with reference to the presence or absence of the web opposite the printheads. | 06-28-2012 |
20130328980 | LOW MOLECULAR WEIGHT AMIDE GELLANTS AND METHODS FOR MAKING THE SAME - Disclosed herein are curable solid inks which are solid at room temperature and molten at an elevated temperature at which the molten ink is applied to a substrate. In particular, the curable solid inks of the present embodiments comprise low molecular weight amide gellants that impart self-leveling capabilities to the inks. Also disclosed herein are methods for making the amide gellant and the inks comprising the amide gellants. | 12-12-2013 |
20140028747 | System and Method for Spreading Ink on a Media Web - A leveling and spreading system has been developed that enables the speed and position of the web to be determined from a sensor on a first roller. In a duplex print process, the first roller also reduces a temperature of the media web and an ink image printed in the first side print operation to within a first predetermined temperature range. A second roller modulates the temperature of the media web and ink ejected onto the media web immediately before the web enters the leveling and spreading system to within a second predetermined temperature range to enable uniformity of the ink and web temperatures for spreading the ink in a nip formed with a third roller. | 01-30-2014 |
20140123873 | CURABLE SOLID INKS CONTAINING CYCLOHEXYL-BASED CRYSTALLINE GELLANTS - Disclosed herein are curable solid inks which are solid at room temperature and molten at an elevated temperature at which the molten ink is applied to a substrate. In particular, the curable solid ink of the present embodiments comprises a cyclohexyl-based crystalline gellant that impart self-leveling capabilities to the inks, where the cyclohexyl-based crystalline gellant have a structure of Formula I: | 05-08-2014 |
20140204150 | Release Agent Composition For Solid Inkjet Imaging Systems For Improved Coefficient Of Friction - A functional amine release agent displaying reduced coefficient of friction as compared to standard silicone oils, the release agent comprising a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl; wherein the concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0006 meq/g. According to certain embodiments, the functional amine release agent is operable to impart a coefficient of friction of about 0.3 or more to the print media, resulting in improved finishing and converting equipment interaction. | 07-24-2014 |
20140267482 | Device And Method For Addressable Spray-On Application Of Release Agent To Continuous Feed Media - A module is configured to selectively apply release agent to a web having a sequence of printed imaged formed thereon by a printer. The module includes a plurality of dispensers arranged in a cross-process direction across the imaged web. The module detects positions of areas in the printed images and determines whether the amount of ink in the areas meet or exceed a predetermined density threshold. If an area meets or exceeds the threshold, a controller operates a dispenser to apply release agent to the area on the web as the area passes the dispenser. The controller operates the dispensers with reference to image data of the surface of the web. | 09-18-2014 |
20150306867 | Release Agent Composition For Improved Coefficient of Friction - A functional amine release agent displaying reduced coefficient of friction as compared to standard silicone oils, comprises a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl. The concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0001 meq/g. According to certain embodiments, the functional amine release agent is operable to impart a coefficient of friction of about 0.5 or more to the print media, resulting in improved finishing and converting equipment interaction. The release agent may have a viscosity of about 50 cSt. | 10-29-2015 |
20150307727 | Release Agent Composition For Tandem Solid Inkjet Imaging Systems Having Improved Wettability - Functional amine release agents displaying improved wetting as compared to standard silicone oils comprise a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl, in which the concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0006 meq/g and the release agents have a viscosity of 20 cSt and 10 cSt. In an in-line tandem print system, the 20 cSt release agent is used in the upstream print engine while the 10 cSt release agent is used in the downstream print engine. | 10-29-2015 |
