The present invention relates to water based wax dispersion comprising a hydrocarbon wax and a dialkylether for the coating of paper products, the use thereof, the method of coating paper products therewith and the coated printed paper product.

A method of producing an apparent etched or embossed effect in a print purely by the use of printing and lamination processes, in which a varnish 3 is pressed into to selected areas of a softer coating 2 to produce indentations in the coating layer 2 as during lamination of a printed article comprising a substrate 1 and an optional overlay 4, and a printed article obtainable using the method.

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.

The present invention relates to a method of forming an image on a substrate comprising a transparent or translucent composition applied thereto, wherein the transparent or translucent composition comprises a protein in a non-denatured state, and the method comprises applying radiation to the transparent or translucent composition to denature the protein and thereby form an image on the substrate. The invention also relates to a method of preparing a substrate on which an image can be formed, and related substrates, compositions and uses thereof.

A device for applying an adhesive powder to a transfer film is disclosed. The device houses a film tray arranged to receive a transfer film thereon. A first hopper is mounted at an upper position above the film tray to receive an adhesive powder therein for release onto a transfer film during a coating process. A second hopper is mounted at a lower position below the film tray to collect excess adhesive powder fallen from the transfer film. Upon being emptied of adhesive powder, the first hopper may be removed from the upper position to replace the second hopper in the lower position, and the second hopper may be removed from the lower position to replace the first hopper in the upper position to enable release of the excess adhesive powder from the second hopper onto a transfer film in a subsequent coating process.

A method for safely differentiating a three dimensional object subsequent to its creation and varnish protection by means of applying and sealing a decoration and/or data between the original and a final varnish layers. The three dimensional object may be decorated and/or contain data from its original manufacturing process but it may also be protected by a varnish prior to utilizing this process. The method enables the addition of decoration and data at any time or location subsequent to the original manufacturing process. The process takes place on top of the original varnish and may be subsequently sealed by applying another varnish layer.
