Systems and techniques for improving ink jet ink durability and adhesion to a substrate. The techniques may include applying a varnish to the surface of the substrate, curing, in an initial curing step, the varnish with an ultraviolet (UV) lamp, and applying a pigmented ink to at least a portion of the substrate. The initial curing step may comprise pinning the varnish with the UV lamp in a low-power state. The techniques may additionally or alternatively include applying a layer of pigmented ink and varnish at substantially the same time, allowing the pigmented ink and varnish to at least partially mix, then pinning or curing the ink/varnish combination.

A printing device and a printing method, which are by ink-jet technique an overcoat layer using an ink consisting of more suitable ingredients, are provided. The printing device is for performing printing by ink-jet technique, including: a color ink head being an inkjet head that forms a color ink layer on a medium using a color ink; an overcoat head being an inkjet head that forms an overcoat layer that covers the color ink layer; and a curing agent head being an inkjet head that discharges ink droplets of a curing agent, the curing agent being a liquid for curing an ink in the overcoat layer. The overcoat head discharges ink droplets of an ink prepared by dispersing in an organic solvent a curable material that is cured in reaction to the curing agent.

A method is disclosed for applying an antibacterial coating onto a substrate having one or more layers of print. In a printing press, one or more layers of print are applied to a substrate in a printing step. A finishing composition is applied over the layers of ink by a finishing stage in a finishing step to form a continuous outer protective layer. The finishing composition is applied to the substrate by a roller. The printing step and the finishing step are performed simultaneously. The finishing composition includes an antibacterial additive.

A thermal sensitive media for use with labeling or identification methods is disclosed. The thermal sensitive media comprises a media layer and a thermally sensitive record layer formed upon at least one surface of the media layer. The thermally sensitive record layer forms a visually discernable colored image in response to heat. However, the colored image is subject to degradation as a result of exposure to ultraviolet radiation within a known photodegradative wavelength range. An ultraviolet protective coating layer may then disposed over the thermally sensitive record layer. A lamination layer is positioned internal to the media layer and comprises a matrix of micro heating elements driven by radio frequency (RF) power. The matrix of micro heating elements are arranged in a pin array to energize the micro heating elements within the laminated media structure to create a simple numeric image.

A ceramic ink may include about 20% to 80% by weight oxide frit, wherein the oxide frit is particles of at least one compound selected from silica, titania, alumina, zirconia, a compound having fluoride ion, bismuth oxide, zinc oxide, boron oxide, potassium oxide, sodium oxide, calcium oxide, barium oxide, lead oxide, lithium oxide, phosphorous oxide, molybdenum oxide, strontium oxide, and magnesium oxide; about 10% to 40% by weight infrared or near-infrared transmissive or reflective inorganic pigment; and about 10% to 40% vehicle.

A method for manufacturing decorative surfaces includes the steps of a) inkjet printing a color pattern on a paper substrate with one or more aqueous inkjet inks of an aqueous inkjet ink set; and thereafter b) impregnating the paper substrate with a thermosetting resin, wherein the aqueous inkjet ink set includes a cyan aqueous inkjet ink containing a copper phthalocyanine pigment; a red aqueous inkjet ink containing a pigment C.I Pigment Red 254 or a mixed crystal thereof; a yellow aqueous inkjet ink containing a pigment C.I Pigment Yellow 151 or a mixed crystal thereof; and a black aqueous inkjet ink containing a carbon black pigment; with the proviso that the aqueous inkjet inks do not include a polymer latex binder; and that the paper substrate includes one or more ink receiving layers for improving the image quality of the aqueous inkjet inks jetted thereon.

The invention relates to a method of producing three-dimensional structural surfaces based on synthetic resin-impregnated materials applied to the surface, in particular of wood-based panels. The method is characterized in that before the impregnation, at the stage of pattern printing, a mixture is applied to the decor paper, consisting of printing ink, whether with pigment or not, and a swelling agent in the form of microspheres, being encapsulated gas bubbles of sizes ranging from 2 pm to 180 pm, increasing its volume under the influence of rising temperature, wherein the mixture of the ink and the swelling agent contains from 0.3% to 45% by weight of the swelling agent, and after exiting the printing press and after the impregnation, the decor paper with the formed final pattern with a coded three-dimensional structure is pressed onto the surface, in particular of a wood-based panel, using a heated press plate with any working surface.

An ink jet recording method includes a step of forming a first image containing a first liquid and a coloring material on an ink receiving medium and a liquid absorbing step of bringing a liquid absorbing member including a porous body into contact with the first image to absorb at least some of the first liquid from the first image to form a second image.

The present invention provides a method for applying multiple ink and/or coating layers on a substrate. At least one of the ink and/or coating layers contains one or more photoinitiators, and at least one of the ink and/or coating layers does not contain any photoinitiators. In certain embodiments, all of the ink and/or coating layers are wet trapped and the entire print construct is cured by exposure to UV radiation after all of the ink and/or coating layers have been applied. In certain embodiments, the wet trapping method of the present invention can be used to prepare laminates.

A method for processing floorboards using digital printing, comprising: preparing a base material layer; arranging a printing layer on the base material layer, wherein the printing layer is directly printed by a digital printing apparatus and is formed on a surface of the base material layer; and arranging a protection layer on the printing layer, wherein the protection layer is attached to the printing layer by means of one or a combination of processes selected from roll-coating, shower-coating, spray-coating, transfer-printing and printing, wherein the protection layer displays one or a combination of artistic effects selected from flat, sunken, raised, finely creased, patterned and crackled by means of one or a combination of processes selected from levelling, flatting, printing, embossing, corroding, carving, brushing and crackling. According to the processing technology of the present disclosure, various patterns can be designed and processed in different ways or combinations according to the user's requirements.
