Abstract: A method for obtaining a raised pattern on a substrate and to the device used, wherein the method includes the following steps of moving a substrate having one face; supplying a with a first face; projecting onto the first face a raised-pattern product using digital printing technology so as to generate a positive raised pattern on the first face; fixing the positive raised pattern on the film; applying an overlay product; obtaining a negative raised pattern on the overlay product by contact with the positive raised pattern; and fixing the negative raised pattern on the face of the substrate.

Abstract: 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.

Abstract: 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.

Abstract: A system for applying a product (3) by roller is disclosed. The system has an applicator roller (1) for applying a product (3) on a substrate (4) and a first dosing roller (2?) for dosing said product (3) on the surface of the applicator roller (1), wherein the system comprises at least one second dosing roller (2?) configured to fine-tune the dosing performed by the first dosing roller (2?), thereby adjusting the amount of product (3) dosed on the surface of the applicator roller (1).

Abstract: A method for applying a product by roller on a surface of a substrate (112) transported horizontally with respect to an application head (111, 111?) is discloses. The method includes moving the application head (111, 111?) immediately from a lowered position of the application head (111, 111?), wherein the application roller (122, 122?) applies the product in a predetermined position of the surface of the substrate, to a raised position of the application head (111, 111?), wherein the application roller (122, 122?) does not apply product; or vice versa. An application system using the method for applying a product by roller is also disclosed.

Abstract: A vacuum system for securing substrates is provided, having a suction line, the conveyor belt configured to receive and transport at least one substrate, wherein the conveyor belt is provided with a plurality of perforations, wherein the vacuum system is configured to produce fluid suction through the perforations towards the interior of the suction line, generating a securing force of the at least one substrate to the conveyor belt. The invention is characterized in that each perforation is equipped with a valve which allows the opening and closing of the perforation, allowing and impeding, respectively, the passage of a fluid flow through the perforation.

Abstract: A substrate printing system is disclosed having a perforated conveyor belt adapted for transporting on the same a substrate to be printed, wherein the perforated conveyor belt has a set of perforations; a perforated grill which has a set of perforations and which is configured such that the perforated conveyor belt can be moved over the perforated grill; and a suction chamber which has a suction element, the suction chamber being in communication with the perforated conveyor belt and with the perforated grill such that the suction flow created by the suction element is adapted for passing through perforations of the perforated conveyor belt and of the perforated grill to secure the substrate to the perforated conveyor belt.

Abstract: The invention relates to a vacuum system for securing items in printing machines, comprising a printing table (2) with a perforated surface and, in relation thereto, a vacuum system for securing the items to be printed, which comprises a box structure (8) connected to a suction system and provided with a perforated wall in relation to the surface of the printing table (2), said box structure (8) having lateral panels that vertically close the interior thereof, which panels can be moved in order to adjust the gap between them in relation to the width of the items to be printed.
