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.

An approach is provided for applying a release agent to a substrate having a first surface and a second surface. The approach involves determining a presence of at least one ink image applied to at least one portion of one of the first surface and the second surface of the substrate by way of one or more steps of a printing process. The approach also involves determining the substrate is to be made ready for printing one or more other images on the other of the first surface and the second surface by one or more steps of another printing process. The approach further comprising causing, at least in part, the release agent to be applied to the substrate so as to cover the at least one portion of the first surface and the second surface of the substrate upon which the at least one ink image is applied at a time before the substrate is subjected to the one or more steps of the another printing process.

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.

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: wherein each X, Y, p, q, R, R, R, and Rare as defined herein.

An inkjet printer and method therefore including a detector to monitor a quantity of release agent applied to a spreader drum. The inkjet printer includes a drum maintenance unit which applies the release agent to the spreader drum with a metering device, such as a metering blade, and determines a flow rate of unused release agent returned to a release agent sump. The determined flow rate of release agent provides a determination of the quantity of release agent applied to the spreader drum. Upon the determination that too much release agent has been applied based on the flow rate, an alert signal is generated indicating that the metering blade should be inspected and replaced if necessary. Monitoring the amount of release agent applied to the spreader drum in this way enables a more robust printing and in-line coating system.

An approach is provided for applying a release agent to a substrate having a first surface and a second surface. The approach involves causing, at least in part, a release agent supply device to supply release agent to a release agent applicator. The approach also involves causing, at least in part, a release agent metering device configured to control an amount of release agent applied to a roller configured to apply release agent to the first surface of the substrate. The roller is configured to accommodate the substrate under a tension over at least a portion of a circumference of the roller such that a pressure is exerted between the roller and the first surface of the substrate.

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.

An inkjet printer and method therefore including a detector to monitor a quantity of release agent applied to a spreader drum. The inkjet printer includes a drum maintenance unit which applies the release agent to the spreader drum with a metering device, such as a metering blade, and determines a flow rate of unused or excess release agent returned to a release agent sump. The determined flow rate of release agent provides a determination of the quantity of release agent applied to the spreader drum. Upon the determination that too little release agent has been applied, at least one function of the inkjet printer is disabled to stop the flow of release agent and to facilitate maintenance if necessary.
