摘要:
An intermediate transfer member (ITM) for use in a printing system to transport an ink image from an image forming station to an impression station for transfer of the ink image from the ITM onto a printing substrate, wherein the ITM is an endless flexible belt of substantially uniform width which, during use, passes over drive and guide rollers and is guided through at least the image forming station by means of guide channels that receive formations provided on both lateral edges of the belt, wherein the formations on a first edge differ from the formations on the second edge by being configured for providing the elasticity desired to maintain the belt taut when the belt is guided through their respective lateral channels.
摘要:
A method for treating a hydrophobic release layer of an intermediate transfer member for use in a printing process in which a negatively charged aqueous inkjet ink is jetted onto the surface of this layer. The method comprises contacting the release layer with a chemical agent which is an amine functionalized silicone. Transfer members comprising such a treated release layer and images printed therefrom are also disclosed.

An aqueous inkjet printer is configured to reduce condensation of vapor on printhead faces. The printer includes air directing members between adjacent printheads in a process direction and an air mover pneumatically connected to the air directing members. The air mover is operated selectively to remove vapor in the air between adjacent printheads as an ink image is formed on an image receiving surface moves past the adjacent printheads.

An image recording method includes applying a reaction liquid onto an intermediate transfer member, applying an ink onto the reaction liquid on the intermediate transfer member, forming an intermediate image by applying a liquid composition containing a water-soluble polymer onto the reaction liquid and the ink on the intermediate transfer member, and transferring the intermediate image by bringing the intermediate image on the intermediate transfer member into contact with a recording medium and separating the intermediate image from the intermediate transfer member with the contact with the recording medium maintained. The intermediate image to be brought into contact with the recording medium has a temperature Tc higher than or equal to the glass transition temperature of the water-soluble polymer, and the intermediate image to be separated from the intermediate transfer member has a temperature Tr lower than the glass transition temperature of the water-soluble polymer.

A recording method includes: applying a reactant configured to thicken upon contact with ink to an intermediate transfer body; forming an intermediate image by applying ink to the intermediate transfer body; applying an auxiliary liquid containing a water-soluble polymer to the intermediate image to form an intermediate image layer; and transferring the intermediate image layer to a recording medium. At least one of the reactant, the ink, and the auxiliary liquid contains a certain compound. The reactant contains a surfactant different from this compound and having a cloud point. The temperature of the intermediate image layer at contact with the recording medium is equal to or higher than both the cloud point of the surfactant and the glass transition temperature of the water-soluble polymer, and that at release from the intermediate transfer body is lower than the glass transition temperature of the water-soluble polymer.
