The printing press in the conveying path for the substrate between the feeding device and the delivery unit further comprises an in-line casting device adapted to apply a layer of material acting as an optical medium on a portion of the second side of the substrate and to replicate and form a micro-optical structure in the layer of material acting as optical medium, wherein the printing unit comprises a first printing group comprising a printing cylinder and being adapted to print at least one printed pattern on the first or second side of the substrate in register with the micro-optical structure.

A method for decorating substrates, in particular packaging, comprising the steps: printing at least one first decorative pattern (2) on the substrate using a first radiation-curable, preferably UV-curable, printing ink composition (3); printing at least one second decorative pattern (4), using a second radiation-curable, preferably UV-curable, printing ink composition (5), on at least part of the substrate (1) in a region near to the first pattern (2), chronologically before, after, or during the printing of the first pattern; radiation curing of the first and second printing ink compositions (3, 5), preferably directly after the printing of each pattern, the radiation-cured second printing ink composition having a lower glass transition temperature than the radiation-cured first printing ink composition; application of a decorative coating to the second pattern by means of a hot foil stamping process, a hot stamping foil comprising a decorative coating material being pressed against the printed substrate by means of a stamping tool under the application of heat and pressure such that the decorative coating adheres to the second pattern but not to the first pattern.

A method for providing a roller assembly for producing a decorative pattern on a wood material surface, wherein the roller assembly comprises at least one decorative paint roller and at least one structured lacquer application or embossing roller, and the structured lacquer application or embossing roller and the decorative paint roller are matched to create a structured decorative pattern, includes the steps of applying first the decorative paint roller and then the structured lacquer application roller on the wood material surface. The method uses at least two different decorative paint rollers for creating two different decorative patterns are matched with a structured lacquer application or embossing roller.

Disclosed herein is a method for forming a surface relief microstructure, including the steps of A) applying a curable composition to at least a portion of the frontside of the paper substrate, B) contacting at least a portion of the curable composition with surface relief microstructure, C) curing the composition by using at least one UV lamp which is arranged on the backside of the paper substrate, and D) depositing a metallic layer, and optionally a layer of a transparent high refractive index material, on at least a portion of the cured composition, wherein the UV lamp has an emission peak in a UV-A range of 320 nm to 400 nm and additionally in a near VIS range of 400 nm to 450 nm, the curable composition comprises a photoinitiator which absorbs in the UV-A range and also in the near VIS range.

The invention relates to a method for producing an edge profile for a narrow surface of a plate-shaped material, wherein an edge band extending in a longitudinal direction has a decoration, and wherein the edge band has a three-dimensional structure. In order to further improve a furniture part with regard to optical and haptic properties, the decoration and the structure according to the invention are arranged in such a way that the structure is at least substantially congruent with the decoration. The invention further relates to a corresponding furniture part having a plate-shaped material, which has at least one narrow surface, an upper part, and a lower part, and at least one edge profile.

A method and an apparatus for forming a surface relief microstructure, especially an optically variable image on a paper substrate are provided, the method comprising the steps of: A) applying a curable composition to at least a portion of the frontside of the paper substrate; B) contacting at least a portion of the curable composition with surface relief microstructure, especially optically variable image forming means; C) curing the composition by using at least one UV lamp (1, 2, 3) which is arranged on the backside of the paper substrate; D) optionally depositing a layer of a transparent high refractive index material and/or a metallic layer on at least a portion of the cured composition, wherein the lamp (1, 2, 3) having emission peak(s) in the UV-A and near VIS range and the curable composition comprises at least a photoinitiator which absorbs in the UV-A region and preferably in the near VIS range. A paper product obtainable uses the method and an apparatus for forming a surface relief microstructure on a paper substrate. Surface relief microstructures, such as holograms may be replicated rapidly and with accuracy on a paper substrate by using the method and the apparatus.

An embossed sheet configuring a decorative sheet includes a sheet-shaped base that has translucency, and a plurality of reflective portions provided on one surface of the base. Each of the plurality of reflective portions has a reflective main surface that reflects incident light, and connecting surfaces that are provided between the reflective main surface and the base. Each reflective main surface is rectilinear on a first cross-section and curvilinear on a second cross-section. A gradient of a straight line at a center position of the reflective main surface that is rectilinear on the first cross-section, in relation to the one surface of the base, varies within a range of 40 degrees in each of the plurality of reflective portions. As a result, the reflective portion can reflect incident light at regular and non-regular angles.
