Abstract
A printing method includes forming an image by applying marking material onto the surface of a substrate; subjecting the image to a fixation treatment; and applying a layer of an ionically stabilized varnish on the surface of the image. When the image has been formed, a layer of liquid solvent is formed on at least a part of the surface of the image, thereby causing ions to migrate from the marking material into the solvent and then to be absorbed into the substrate together with a part of the solvent before the varnish s applied.

A printing method comprising the steps of:
- forming an image by applying marking material onto the surface of a substrate;
- subjecting the image to a fixation treatment;
- and
- applying a layer of an ionically stabilized varnish on the surface of the image,
- wherein, when the image has been formed, a layer of liquid solvent is formed on at least a part of the surface of the image, thereby causing ions to migrate from the marking material into the solvent and then to be absorbed into the substrate together with a part of the solvent before the varnish is applied.
A printing system comprising a primer application unit, a print engine, a fixation unit and a varnish applicator disposed in that order along a transport path for print substrates, wherein the fixation unit is configured for blowing super-heated steam against the surface of the substrates.
