A method for producing a decorative surface having different gloss levels preferably comprising the following steps: (C) feeding of a workpiece (1.0), which is coated with at least a first lacquer layer (1.4) to a digital printing station; (D) provision of digital control data for the digital printing station; (E) digital spraying of droplets on partial areas of the first lacquer layer (1.4) on the workpiece (1.0) with an at least partially transparent lacquer in order to apply a second lacquer layer (1.5) on the first lacquer layer (1.4), wherein after curing the second lacquer layer (1.5) has a different gloss level than the first lacquer layer (1.4).

Further disclosed is an apparatus for carrying out this method.

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.

The present invention is a method for measuring the varnish film thickness of a printed article by obtaining the film thickness of varnish on a sheet (1) on which a pattern is printed on a base thereof with ink and the pattern is coated with the varnish, wherein a metal foil (1c) having a smooth surface is attached to the base of the sheet (1), and the film thickness of the varnish coated directly over the metal foil (1c) is detected with a spectral interference-type film thickness meter (81) so as to determine whether the film thickness of the varnish is acceptable or not on the basis of the results detected by the spectral interference-type film thickness meter (81).

A drying assembly comprises a plurality of electromagnetic energy sources arranged to dry printing fluid deposited onto a surface of a substrate, by evaporation of a solvent fluid therefrom. The drying assembly further comprises a conveyor system configured to move the substrate in a conveying direction, and a focusing system configured to focus electromagnetic energy from the plurality of electromagnetic energy sources to form a non-uniform heating pattern on the surface of the substrate. The non-uniform heating pattern comprises a plurality of spatially separated higher and lower intensity regions distributed along the conveying direction.

This disclosure describes systems, methods, and apparatus for decorating a can comprising a base, a curvilinear side surface extending in an upward direction from the base and comprising a neck and flanged portion, wherein the base and curvilinear side surface are formed using a metallic material, and at least one layer each of a first ink and a first overvarnish applied on at least a portion of the curvilinear side surface. The method further comprises surface treating the curvilinear side surface to increase a surface energy of the first overvarnish, applying one or more layers of an obscurant coating to the portion of the curvilinear side surface, wherein the portion may or may not include the neck and flanged portion, applying one or more layers of a second overvarnish and/or second ink to the portion of the curvilinear surface of the can, and curing the can.

An ink-receptive composition for coating a substrate provides outstanding outdoor durability and color fade resistance. The ink-receptive composition includes a polymeric binder comprising an ethylene-based polymer, a pigment, a light stabilizer package comprising UV-absorber and a light stabilizer, and a surfactant. Notably, the ink-receptive composition is preferably free of mordant, if any mordant is present, then that mordant is present in an amount less than 5 weight percent of the composition and more preferably less than 3 weight percent of the composition, Related methods of manufacture, methods of printing, and articles coated with the composition are obtainable with this coating.

The inventions relates to a method for producing a decorative workpiece with a structured surface comprising the following steps: (B) applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm; (E) applying a second liquid, at least partially transparent lacquer for producing a fine structuring in some regions. Furthermore, an apparatus for performing the method and a workpiece produced by the method are claimed.

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.
