Abstract: The invention concerns a method and/or a system for personalizing substrates and/or preparing substrates before gold-plating. In particular, the invention consists of a printing method comprising a step in which the substrate is subjected to inkjet printing followed by a gold-plating step in which the regions of the substrate to be gold-plated are brought into contact with the gold-plating leaf, characterized by an additional step performed prior to the gold-plating step and which consists in the preparation of the substrate.

Abstract: The invention relates to a novel device and a novel method for transporting printable substrates in a precise manner, suitable for various types, sizes and thicknesses of substrate. The invention is also suitable for printing machines that do not come into contact with the substrate, such as ink-jet printing machines.

Abstract: The present invention relates to a varnish which is for covering the surface of a substrate and deposited by inkjet, to a process for preparing said varnish and to the use thereof as a laminable and/or overprintable ink or varnish.

Abstract: The present invention relates to a substance(s) deposition control device for an offset printing system comprising at least one offset plate intended to receive at least one substance so as to transfer the substance or substances onto a substrate, at least one means for the controlled deposition of at least one substance, the deposition means comprising at least one head unit spraying at least one wetting solution and at least one head unit spraying at least one colored substance, at least one means for cleaning the offset plate. The covering of the offset plate comprises a mesh structure defined by a plurality of hydrophilic and lipophilic individual surfaces capable of receiving a controlled deposition of substance(s), each of these hydrophilic and lipophilic individual surfaces being separated from its direct neighbors by at least one hydrophobic and lipophobic peripheral surface. The invention also relates to a printing system incorporating the device and to a printing process implementing the device.

Abstract: The present invention relates to a substance(s) deposition control device for an offset printing system, characterized in that it comprises:—at least one offset plate intended to receive a wetting liquid and a colored substance in succession,—at least one controlled-deposition means for each offset plate, the deposition means comprising at least one deposition head spraying at least one wetting solution and at least one deposition head spraying a defined colored substance,—at least one means for cleaning the offset plate, and in that the covering of the offset plate or plates comprises a mesh structure defined by a plurality of hydrophilic and lipophilic individual surfaces capable of receiving a controlled deposition of wetting liquid and/or colored substance, each of these hydrophilic and lipophilic surfaces being separated from its direct neighbors by at least one hydrophobic and lipophobic peripheral surface.

Abstract: The aim of the present invention is to propose a method for assessing and correcting the alignment of print heads carried out using at least one linear adjustment algorithm, allowing greater accuracy in the use of same by eliminating inaccuracies linked to the ejection of drops from the print heads, while limiting the use of the resources of the IT system on which the method is used. Moreover, the number of print heads of which the alignment needs to be assessed and optionally corrected has very little influence on the overall processing time required by said method.

Abstract: The invention concerns a contactless numerical printing machine for products of average fluidity, such as varnish, glue, and conducting or scratchable ink, onto a substrate of variable thickness and dimensions. The machine includes a special device for printing without contact by projection. The projected materials are materials of average fluidity or composed of large-dimension molecules. The process used includes an electro-acoustic device for control of the projection, and a multiplicity of projection nozzles, each controlled individually. The machine also includes a production chain with different work stations, whose printing devices are controlled by a computer management system. The production chain allows printing with a certain precision in given zones located during the processing by an appropriate work station.

Abstract: A press for documents or patterns printed with powder ink on a plastic or paper substrate has a controller for applying pressure and heat to one or more printed substrates or to a stack of plural printed substrates. The controller includes heating plates that cause the applied pressure and heat to be such that the pressure and temperature of the substrate(s) or stack has at least one specified pressure and temperature, in accordance with specified cycles. During the cycles, the controller varies the applied temperature and pressure for a specified duration. The stack includes at least one plate for separating the printed substrate(s) while the heat and pressure are applied. The heating and separating plates include finished surfaces for providing a finish to the printed document. A protective film is located between the finished surfaces and printed faces of the substrates while the pressure and heat are being applied.
