Provided are a fiberboard structure manufacturing method, a fiberboard structure manufacturing system, and a fiberboard structure, in which preferred inkjet type printing on a substrate to which a fiberboard is applied is implemented. A fiberboard structure manufacturing method includes: applying an aqueous sealer to a first surface of a substrate in which a fiberboard is used; forming an undercoat layer in which the aqueous sealer is dried, on the first surface; applying an aqueous preconditioning liquid having a function of thickening an aqueous ink to the first surface on which the undercoat layer is formed; and jetting the aqueous ink from an inkjet type jetting head to apply the aqueous ink to the first surface on which the aqueous preconditioning liquid is applied.

A method and equipment to form a digital print by applying dry colourants on a surface of a panel, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colourants on the liquid binder and the surface; bonding a part of the colourants to the surface with the liquid binder; removing non-bonded colourants from the surface such that a digital print is formed by the bonded colourants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colourants are permanently bonded to the surface.

A manufacturing method of decorated natural leather includes applying a base coat on crusted leather, inkjet printing a decorative image on the base coat using one or more pigmented inkjet inks, and applying one or more identification codes.

Provided is an ink composition to be used on a leather substrate, wherein the ink composition is capable of forming an ink film having more abrasion resistance and flexibility and forming a clearer image. An ink composition to be used on a leather substrate that contains at least a coloring material, a resin, and an organic solvent, does not contain water, and the organic solvent contains a solvent represented by general formula (1).

n: integer of from 1 to 4, R.sub.1: C1-8 optionally branched alkyl group, R.sub.2: C1-4 optionally branched alkylene group, R.sub.3: hydrogen or C1-4 optionally branched alkyl group.

A skin printing solution system includes a skin printing device that provides a user with a skin printing solution user interface including an online art gallery, a skin printing server that provides the online art gallery to the skin printing device, and a skin printer that outputs a tattoo image received from the skin printing device to a print region. Herein, when the user selects a tattoo image through the skin printing solution user interface, the skin printing device receives the selected tattoo image from the skin printing server and transmits the received tattoo image to the skin printer. In addition, the online art gallery includes multiple tattoo images, and the print region is the skin of the user or a different user.

The disclosure relates to a method for printing a decoration to be printed onto a plurality of print surfaces by digital printing equipment. The method includes: providing a digital template and reference measurement data of a decoration to be printed, said data being hyperspectral and spatially resolved, printing the decoration to be printed onto a print surface using the digital template, measuring measured variables of the decoration printed on the print surface (20), thereby obtaining print measurement data that are hyperspectral and spatially resolved, comparing the print measurement data with the reference measurement data and determining a measure of deviation of the print measurement data (6) from the reference measurement data, modifying the digital template if the measure of the deviation meets a predetermined criterion, and repeating the above steps.

An adhesive bandage is combined with temporary tattoos. When the bandage is removed with water, a temporary tattoo is transferred to the skin. In some embodiments, the adhesive bandage can comprise a base strip, an adhesive layer, a pad, a protective strip and a temporary tattoo assembly, further comprising of at least an ink layer and a release coating.

Method of decorating natural leather with an inkjet printer which comprises:—a first vacuum belt (150) for conveying an unwoven fabric (200) which is configured as a second vacuum belt, for conveying under an inkjet print head (505) a natural leather (300); and wherein the method comprises:—applying from an adhesive tape-roll an adhesive tape (1300) as a continuous sheet against the unwoven fabric wherein said adhesive tape (1300) has an adhesive side and opposite side and the opposite side is in contact with the unwoven fabric;—applying a natural leather (300) on the adhesive side of the adhesive tape (1300);—conveying the applied natural leather by moving the first vacuum belt (150) whereby the unwoven fabric (200) is moving by suction power through the first vacuum belt (150) and the applied adhesive tape (1300) is moving by said suction power through said unwoven fabric (200) under an inkjet print head (505);—marking the applied natural leather with jetted droplets of the inkjet print head (505) for decorating said natural leather while the adhesive tape (1300) is attached to the unwoven fabric (200).

A manufacturing method of decorated natural leather including the steps of: attaching a crusted leather (45) with its corium side by an adhesive (46) to a temporary carrier (47); inkjet printing the crusted leather (45) on its grain side with one or more pigmented inkjet inks; wherein the surface area of the temporary carrier (47) is larger than the surface area of the crusted leather (45).

An ink used for printing on a leather includes: a coloring material, an organic solvent, and a resin; where a maximum tensile stress of an ink film formed of the ink is 2 N/mm.sup.2 or more.
