Intaglio gravure printing machine and method for applying at least one printing fluid to at least one substrate

The invention relates to an intaglio gravure printing machine according to the preamble of claim 1 and a method for applying at least one printing fluid to at least one substrate according to the preamble of claim 25.

DE 102013223826 A1 shows a gravure printing machine with a forme cylinder and an impression cylinder.

EP 2 979867 A1 discloses a printing machine with a cylinder which has a printing plate with depressions. An inkjet printer prints ink into the depressions in the printing plate. The ink is transferred to a printing substrate and dried before the printing substrate is removed from the cylinder.

DE 69631 782 T2 teaches a printing system with a printing element in the form of a gravure cylinder for selectively receiving ink in an ink receiving area in the form of depressions with several ink receiving points. An ink image is formed on a part of the ink-absorbing dots by at least one printing unit for applying ink to the printing element. The ink image is transferred to a printing substrate by a transfer system with a printing cylinder.

DE 102012 017284 A1 teaches a device for printing printing material which comprises a first printing machine cylinder contacting the printing material in a printing nip and a second printing machine cylinder. The second printing press cylinder transfers a previously applied print image of a first printing ink onto the printing material. An inkjet printer brings in additional variable print image made of ink directly on a color-free peripheral section of the second printing press cylinder.

The invention is based on the object of creating an intaglio gravure printing machine and a method for applying at least one printing fluid to at least one substrate.

The object is achieved according to the invention by the features of claim 1 and claim 25. The dependent claims show advantageous developments and / or embodiments of the solution found.

The advantages that can be achieved with the invention consist in particular in the fact that a compact and easy-to-use printing machine, in particular designed as a gravure printing machine, advantageously as an intaglio gravure printing machine, is created. The rotogravure printing machine, preferably an intaglio printing machine, is preferably designed for printing securities. The gravure printing machine, preferably intaglio gravure printing machine, is advantageously distinguished in particular by the fact that it comprises at least one forme cylinder, which advantageously has at least one printing plate with at least one engraving. The rotogravure printing machine, preferably intaglio printing machine, advantageously comprises at least one transport means for supplying substrate to the at least one forme cylinder and / or at least one impression cylinder. At least one inking unit and / or at least one ink collecting cylinder, to which at least one inking unit is preferably assigned, is advantageously arranged on the at least one forme cylinder. Advantageously, the gravure printing machine, preferably intaglio printing machine, in particular the at least one gravure printing unit, comprises at least one printhead, in particular at least one non-impact printhead and / or inkjet printhead, which is arranged on the at least one forme cylinder or on the at least one impression cylinder. Advantageously, the at least one printing plate can be colored and / or colored with printing fluid by means of the at least one print head, in particular inkjet print head, only within the at least one engraving. This enables a particularly thin design of the width and / or also a fine line thickness of the at least one engraving of the at least one printing plate. The pressure fluid is advantageously finely dosed in each case on the at least one pressure plate. Printing fluids that differ from one another can advantageously be arranged on the printing plate in two adjacent and / or two mutually adjacent engravings, in particular without mixing the printing fluids with one another. The use of the at least one print head, in particular an inkjet print head, advantageously ensures economical consumption of printing fluid. In addition, a change of pressure fluid can be carried out and / or carried out easily. The fine metering of printing fluid on the at least one printing plate by the at least one print head, in particular inkjet print head, is advantageously designed to produce high color resolution on the at least one substrate, in particular a respective panel of the at least one substrate.

For example, by arranging at least one wiper device on the at least one forme cylinder, excess pressure fluid can be removed and / or is removed before it is applied to the at least one substrate.

Printing fluids, which are used in gravure printing in particular, have a long drying time. For example, these are therefore not dry when a printed substrate reaches at least one delivery of the rotogravure printing machine. The result is a smearing of printing fluid on the substrate in question and / or an undesired transfer of printing fluid to an adjacent substrate or to parts, for example a side opposite the printed side, of an adjacent substrate in the display. In addition, a stack height of a delivery stack is therefore limited to a maximum of 100 substrates in the case of an arcuate substrate, preferably a maximum of 300 substrates, preferably a maximum of 500 substrates. The arrangement and / or use of at least one print head advantageously enables these disadvantages to be improved. At least one protective layer and / or at least one protective film, which is designed to prevent smearing of pressure fluid, in particular in the at least one display, is advantageously produced on the substrate. Advantageously, at least the printing fluid ejected by the at least one print head is dried before the substrate arrives in the display and / or before a sheet-shaped substrate is deposited on a display stack or before a web-shaped substrate is rolled up in the display. Advantageously, a stack height of at least 100 substrates, preferably of at least 300 substrates, more preferably of at least 500 substrates, more preferably of at least 800 substrates, in the at least one display stack is possible.

In an advantageous embodiment, the gravure printing machine, preferably intaglio gravure printing machine, is characterized in that the at least one printhead, in particular the at least one inkjet printhead, is arranged on the circumference of the at least one forme cylinder, through which the at least one engraving can be colored with at least one printing fluid is and / or is colored. A gravure printing unit of the gravure printing machine, preferably intaglio gravure printing machine, advantageously comprises at least the at least one forme cylinder and the at least one print head, in particular the at least one inkjet print head, and the at least one impression cylinder. The gravure printing machine, preferably an intaglio gravure printing machine, is characterized in particular by a simple structure, in particular the gravure printing unit of the gravure printing machine. Complex printing fluid supply to the at least one forme cylinder via at least one cylinder connected upstream of the forme cylinder along the path of printing fluid, for example at least one ink collecting cylinder and / or at least one stencil cylinder and / or at least one ductor roller, is omitted in the advantageous embodiment of the gravure printing machine. Further advantages can be seen from the description below.
