Abstract:
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.
Abstract:
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.

Abstract:
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.
