A printing method includes forming an image by applying marking material onto the surface of a substrate; optionally applying an intermediate layer onto the substrate; subjecting the image to a fixation treatment; applying a layer of an ionically stabilized varnish on the surface of the image; and performing image-wise gloss control by locally varying at least one of a fixation parameter and a primer application parameter.

Method of forming a varnish-coated image

An aqueous pre-treatment liquid for use in ink jet printing includes water and magnesium-disulfamate. Such pre-treatment composition is non-yellowing and crystal-free and shows good jetting properties. These properties are retained even when a solid co-solvent is added to the composition for anti-curl improvement, thereby enabling to provide non-yellowing pre-treatment liquids with good jetting properties and anti-curl behavior.

Pre-treatment liquid for use in ink jet printing

The present invention relates to a method for applying an image onto a recording medium, using an aqueous ink jet coating, wherein the aqueous ink jet coating includes a cationic polymer and an anionic surfactant. The present invention further relates to a method for preparing such aqueous ink jet coating composition.
