A manufacturing method for decorating natural leather with a decorative image includes applying on a crusted leather a base coat containing a pigment for providing a chromatic colour or an achromatic colour different from black, inkjet printing a colour image on the base coat using one or more pigmented UV curable inkjet inks, optionally applying a protective top coat on the image, and optionally applying a heat pressing or embossing step, wherein the chromatic colour or the achromatic colour different from black of the base coat and the inkjet printed colour image are used in combination to provide the decorative image.

A capsule placed on a beverage bottle. The capsule includes a capsule material layer and at least two layers of security ink on the capsule material layer. Each of the at least two layers has a different chemical composition. At least one layer of the at least two layers includes a first composition having flakes exhibiting full reflection of light received at a predetermined wavelength.

A process for printing multiple layers on a fabric or other material using UV-curable ink that includes a step of printing a first layer on the material and another step of partially curing the first layer. A next step includes printing a partially UV-transparent layer over the first layer and fully curing the UV-transparent layer while simultaneously fully curing the first layer.

Provided is an ink jet liquid composition including an organic solvent, a bifunctional urethane (meth)acrylate oligomer having a weight-average molecular weight of 2,000 to 15,000, a photopolymerization initiator, and a vinyl chloride-vinyl acetate copolymer, in which a content of the organic solvent is 40% by mass or more and 90% by mass or less with respect to a total mass of the liquid composition. Also provided is an ink jet recording method using the ink jet liquid composition.

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.

An inkjet printer (500) for printing on natural leather (300) comprising 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 a device for applying pressure to said natural leather (300) on said second vacuum belt; wherein said device comprises a portion for traversing said natural leather (300) with a rub by a relative movement between said pressure device and said second vacuum belt, carrying said natural leather (300).

Example embodiments of biodegradable cards and systems and methods making the same are provided. A biodegradable card can comprise a biodegradable substrate, a magnetic particle slot within the biodegradable substrate configured to receive magnetic particles, a high coercivity magnetic stripe comprising magnetic particles printed on the biodegradable substrate and encoded with payment account data, and a biodegradable water resistant coating, wherein the coating covers at least the magnetic stripe.

A method is provided for printing a surface of a non-absorbent substrate with an ink to be applied by an inkjet printing device. An ink that contains water as a solvent is used for printing the substrate. An ink having a water content of at least 70% is used. The substrate to be printed is supported by a workpiece support and is moved relative to the inkjet printing device. During this relative movement, ink is applied by the inkjet printing device to the surface of the substrate to be printed. The ink that is applied to the surface of the substrate is heated to a temperature that is above the temperature of the air surrounding the substrate and that is below the boiling point of the solvent contained in the ink. Above a liquid phase of the ink, a vapor layer, consisting of the solvent that is contained in the ink, is formed. The vapor layer that is formed above the liquid phase of the ink is transported away by an air flow emitted by at least one blower nozzle unit. The air output by the respective blower nozzle unit is heated or is dehumidified beforehand. A digital printing press is provided for carrying out this method.

A manufacturing method of decorated natural leather including the steps of applying a crusted leather, having a corium side, a grain side and an edge, on a conveyor system, having a position means, and aligning said crusted leather by moving said edge against said position means; and laminating said aligned crusted leather on a temporary carrier, having an adhesive layer, wherein said corium side is attached by said adhesive layer on said temporary carrier while conveying said crusted leather on said conveyor system towards said temporary carrier and moving said temporary carrier relative to said conveyor system; and inkjet printing on said grain side with one or more pigmented inkjet inks an image by an inkjet printing system.

Some embodiments of the invention relate to an article of manufacturing for printing on a foamed beverage comprising: an ink-jet cartridge; and a sugar-poor and unfermented-wort-based ink formulation disposed within the ink jet cartridge. The unfermented wort is the primary colorant of the ink formulation. In embodiments of the invention, (i) a ratio between the EBC number of the ink formulation and the 25° C. viscosity thereof is at least 400 (centipoise).sup.−1; (ii) the ink formulation is characterized by at least a EBC number of at least 1800 colorant units; (iii) the ink formulation comprises at least 10% wt/wt carbohydrates; (iv) the ink formulation is sugar-poor such that a ratio between a wt/wt% concentration of soluble sugars and a wt/wt concentration of carbohydrates in the ink formulation is at most 0.2 (e.g. ≤0.1 or ≤0.05); and (v) at least 60% of particles of the ink formulation are sub-400 nanometer particles.
