The drive unit drives the transfer roller in a rotation direction about an axis of rotation. An outside contact surface of the lateral wall comprises a plurality of depressions forming a predetermined structure. The transfer roller rolls with the outside contact surface on the work surface of the work piece for transferring the predetermined structure defined by the depressions in the outside contact surface to lacquer previously applied to the work surface by the lacquer application unit.

A method for the continuous in-register embossing of a stretchable film is provided where a repeating printed image or a laminate may be formed by way of the stretchable film in an embossing station. The embossing station may include a rotating embossing roll having an embossed image and an associated rotating counter-roll. The printed image length of the film may be stretched longitudinally before the embossing contact with the embossing roll to a length greater than or equal to or smaller than or equal to the embossed image length or the circumference of the embossing roll. The maintenance of register of the embossing may be achieved by way of a relative speed between the circumferential speed of the embossing roll and the web speed of the film in the embossing station.

The receptor of the inner roll has at least one of a concave portion and a convex portion, and has a diameter reduced portion corresponding to a shape of the shoulder. Further, the inner roll and the outer roll are rotated by the rotating unit.

A can is provided. The can may include a shoulder, which is formed on a side of an upper end of a cylindrical body of the can in a can axis direction to be reduced in a diameter toward a side of a mouth of the can and to have a thickness of 0.1 to 0.3 mm, and has at least one of a concave portion and a convex portion. An inside diameter of the mouth may be 25 to 60 mm, a maximum outside diameter of the shoulder may be 50 to 70 mm, and a ratio of the maximum outside diameter of the shoulder to the inside diameter of the mouth may be 1.05 to 1.58.

A die and counter die system for impressing a relief pattern onto a substrate, including at least one male die including a contact surface and defining a relief pattern, a compressible counter film including a base layer, a contact layer disposed opposite the contact surface of the at least one male die and spaced therefrom, and a compressible layer disposed between the base layer and the contact layer and attached thereto. The contact layer is featureless in a region thereof opposing the relief pattern on the at least one male die. The compressible counter film has a compressibility, in a direction perpendicular to a broad face of the compressible counter film, in the range of 5-30% at 1.35 MPa. The system further includes a compression mechanism adapted to move the at least one male die and the compressible counter film towards one another in an operative mode.

A method and device of embossing individually light-reflecting areas on a foil material, the method and device comprising feeding a foil material into a roller nip between a pair of rollers, wherein the pair of rollers comprises a first roller and a second roller, providing each of the first roller and second roller at their respective surfaces at least in a determined perimeter, respectively with a plurality of polyhedron-shaped positive projections and a plurality of negative projections complementary to the positive projections, whereby the plurality of positive projections are arranged according to a 2-dimensional grid. The plurality of polyhedron-shaped positive projections seamlessly and gaplessly join with those corresponding negative projections at the intended embossing of the foil material, hence enabling a homogeneously jointed embossed polyhedron-like shape in the foil. The method and device further comprise, for the purpose of providing a plurality of light-reflecting areas on the foil material, that are intended to reflect light in line with a table of reflectivity values for the 2-dimensional grid, according to an orientation and shape of each of the plurality of light-reflecting areas, and enabling a perception by the human eye of a user, of the intended reflected light on a determined wide viewing angle covered by reflected light from any of the light-reflecting areas, a step of adjusting for each of the plurality of light-reflecting areas to be provided, an orientation and shape of the corresponding positive projection in the 2-dimensional grid, that is intended to emboss the light-reflecting area.

A method for producing reliefs through digital printing and a digital printing machine is disclosed by method providing a substrate having a first digital print on one of the faces; applying a coating on the face of the substrate with the first digital print; partially drying the coating until a gelled state is obtained; depositing drops of ink to produce a second digital print; applying pressure to the gelled coating using an embossing roller to obtain a three-dimensional structure, the embossing roller configured to receive the second digital print and produce the three-dimensional structure; and completely drying the coating on which the three-dimensional structure has been obtained.

An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.
