Embodiments of the invention relate to a method of indirect printing with an aqueous ink. Related apparatus, systems and treatment formulations are disclosed herein. Some embodiments relate to an aqueous treatment formulation for use with an intermediate transfer member of a printing system. In some embodiments, the system comprises a treatment station disposed downstream of the impression station and upstream of the image forming station for forming a uniform thin layer of a liquid treatment formulation onto a surface of an intermediate transfer member (ITM) at a lower run thereof.

Digital printing process

There is disclosed a method of manufacturing a multi-layered article including a finished outer surface optionally having particular surface properties. The article can be a self-supported strip having a smooth outer surface. The method is, for example, suitable for the preparation of multi-layered articles such as a flexible intermediate transfer member (ITM) for use in an indirect printing system. Uses of such articles are also disclosed.

Method of manufacturing a multi-layer article

Embodiments of the invention relate to a method of indirect printing with an aqueous ink. In some embodiments, an intermediate transfer member (ITM) comprising a silicone-based release layer surface is employed. For example, the release layer surface satisfies at least one of the following properties: (i) a receding contact angle of a drop of distilled water deposited on the silicone-based release layer surface is at most 60°; and (ii) a 10-second dynamic contact angle (DCA) of a drop of distilled water deposited on the silicone-based release layer surface is at most 108°. Related apparatus, systems and treatment formulations are disclosed herein.

Digital printing process and system

An intermediate transfer member (ITM) for use with a printing system, the ITM having (a) a support layer; and (b) a release layer having an ink reception surface and a second surface opposing the ink reception surface, the second surface attached to the support layer, the release layer formed of an addition-cured, hydrophobic silicone material, wherein the release surface of the release layer has relatively hydrophilic properties with respect to the addition-cured, hydrophobic silicone material.

Intermediate transfer member

Embodiments of the invention relate to a method of indirect printing with an aqueous ink. In some embodiments, an intermediate transfer member (ITM) comprising a silicone-based release layer surface is employed. For example, the release layer surface satisfies at least one of the following properties: (i) a receding contact angle of a drop of distilled water deposited on the silicone-based release layer surface is at most 60&#xb0;; and (ii) a 10-second dynamic contact angle (DCA) of a drop of distilled water deposited on the silicone-based release layer surface is at most 108&#xb0;. Related apparatus, systems and treatment formulations are disclosed herein.

A method of indirect digital printing is disclosed herein. The method employs (i) first (e.g. transparent) and second aqueous ink components (comprising colorant particles) and (ii) a target surface (e.g. hydrophobic) of an intermediate transfer member (ITM). A quantity of first ink component is deposited (e.g. by ink-jetting) onto the target surface and partially dried to produce a partially-dried layer thereon. Droplets of the second ink component are deposited onto the partially-dried layer of first ink component to form a wet, colored ink-image. Upon deposition of the droplets of the second ink component, the colorant particles from the second component penetrate into the partially-dried layer of the first ink component. The wet, colored image is dried into a tacky ink-image-bearing residue film which is transferred to the substrate. Physical and/or chemical properties of the first and second ink components as provided by various embodiments are disclosed herein.

Method and apparatus for digital printing

Embodiments of the invention relate to a method of indirect printing with an aqueous ink formulation applied to the surface of the intermediate transfer member. Related apparatus, systems and treatment formulations are disclosed herein.

Digital printing process and method

An aqueous treatment composition for ITM (Intermediate transfer member) of a printing system and a method of printing comprising the step of applying said treatment composition to the surface of an ITM, wherein said treatment composition comprising: at least 3% wt quaternary ammonium salt, at least 1% wt water soluble polymer, and at least 65% wt water. Also disclosed, a printing system comprising a an ITM and treatment station for forming a thin layer of liquid treatment formulation on the ITM surface.
