A system and method for applying an overcoat to a printed image on a substrate generally includes a radiative source that transmits electromagnetic radiation within a predefined wavelength range to the printed image on the substrate to be absorbed by the printed image and heat the printed image to a predetermined temperature range, a depositing device that deposits an overcoating powder onto the heated printed image, the overcoating powder having a melting point within the predetermined range such that upon deposition thereof, the overcoating powder adheres and/or melts onto the heated printed image, and a residual powder removing device that removes any residual overcoating powder not adhered to the printed image or the substrate.

A print control apparatus is configured to transfer transparent protective ink onto an image printed on a substrate. The print control apparatus includes an extraction unit configured to extract a contour of a subject in the image, and a control unit configured to generate print data for transferring the protective ink using a printing apparatus, based on the extracted contour of the subject. The control unit generates the print data by assigning a high gradation value to a contour line corresponding to the extracted contour of the subject, assigning a low gradation value to a region corresponding to the subject, and assigning a mixture of the high gradation value and the low gradation value to an outer peripheral region of the subject.

An ink jet recording method includes layer forming which includes image recording which records an image by discharging an ink composition which contains water and coloring materials on a recording surface of a recording medium having low absorbency or non-absorbency to ink, and protective layer forming which forms a protective layer on the image by discharging a clear ink composition which contains resin particles and substantially does not contain a coloring material; and heating and drying which includes first heating which heats the recording surface at a glass transition temperature or more of the resin particles after the layer forming, and first drying which performs ventilation while heating the recording surface at a heating temperature or less of the recording surface in the first heating after the first heating, in which the drying time in the first drying is two times or more the heating time in the first heating.

A system for applying a coating composition is provided herein. The system includes a first high transfer efficiency applicator defining a first nozzle orifice and a second high transfer efficiency applicator defining a second nozzle orifice. The system further includes a reservoir. The system further includes a substrate defining a first target area and a second target area. The first high transfer efficiency applicator and the second high transfer efficiency applicator are configured to receive the coating composition from the reservoir and configured to expel the coating composition through the first nozzle orifice to the first target area of the substrate and to expel the coating composition through the second nozzle orifice to the second target area of the substrate.

The ink jet recording method according to the present invention includes attaching a resin liquid including a resin to a recording medium; attaching a reaction liquid including a reactant for aggregating or thickening a coloring ink component having a coloring material to an area where the resin liquid is attached; attaching the coloring ink to an area where the reaction liquid is attached by an ink jet method; and attaching a clear ink including a resin.

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.

A method for decorating a natural leather comprising the following steps: a) holding by vacuum suction the natural leather with its corium side to an air-permeable support onto a vacuum support of an inkjet printer; and b) inkjet printing a decorative image on the natural leather wherein the air-permeable support is partly covered by said natural leather. The air-permeable support comprises a fibrous layer in contact with the corium side of the natural leather.

A method for producing a three-dimensional structure on a surface of a flat substrate, a device for implementing the method, and the substrate that can be produced, the method providing the substrate with the surface ready to be treated; applying a relief product in the form of droplets on the surface, such that selected areas of droplets are produced on the surface; applying a covering product to the surface such that it forms a layer over the surface; and fixing the layer of the covering product with the selected areas on the surface being free from the covering product.
