Patent number: 11548300Abstract: A method for operating a printing machine having a processor and a device for detecting features of printing substrates includes storing print jobs with the printing substrates appropriate thereto in a database. Features of at least one printing substrate are detected by using the device. The detected features of the at least one printing substrate are compared by the processor with the printing substrates of the print jobs from the database. The processor selects at least one print job in which the printing substrates of the print jobs from the database correspond to the at least one detected printing substrate or attain a predefined similarity. The at least one print job selected by the processor is subsequently executed on the printing machine.Type: GrantFiled: May 11, 2020Date of Patent: January 10, 2023Assignee: Heidelberger Druckmaschinen AGInventor: Martin Schmitt-Lewen

Patent number: 11544027Abstract: A method of manufacturing print products uses a computer and a printing or further processing machine with a network connection. A customer-requested print product is compared to digital print product models on the computer, and the best matching digital print product model is selected by the computer from the comparison between the saved digital print product models and the customer-requested print product. The computer checks digital print shop models for compatibility with the selected digital print product model, compares the digital print shop model selected as suitable to saved preference models of actual print shops and selects matching preference models of actual print shops for producing the customer-requested print job. After the customer's computer selects at least one suitable actual print shop, the customer-requested print job is produced on at least one printing or further processing machine of the print shop selected by the customer.Type: GrantFiled: August 3, 2021Date of Patent: January 3, 2023Assignee: Heidelberger Druckmaschinen AGInventors: Georg Roessler, Dominic Stahl, Bernhard Wagensommer, Gottfried Grasl

Patent number: 11529815Abstract: A method pretreats a printing material used for ink printing to influence the spreading of ink print dots on the printing material. The spreading behavior is influenced in such a way that the ink print dots spread in an anisotropic way. The anisotropic spreading advantageously allows undesired quality losses in the print that are caused by a failed ink nozzle to be reduced or avoided. The influencing of the spreading behavior may be achieved by an anisotropic application of a liquid, in particular a primer or varnish, to the printing material, or by an anisotropic embossment or print on the printing material or by an anisotropic treatment of the printing material with charged particles, in particular by a plasma or a corona, or with electromagnetic radiation, in particular laser radiation.Type: GrantFiled: July 13, 2018Date of Patent: December 20, 2022Assignee: Heidelberger Druckmaschinen AGInventor: Peter Hachmann

Patent number: 11524422Abstract: In a method of operating a flat-bed die-cutter a printing substrate in the form of a web is fed to a die-cutting module of the flat-bed die-cutter, a web section is severed from the web and removed as waste. The web is guided through the die-cutting module and the web section is severed from the web in or downstream of the die-cutting module and removed as waste. Products are thus formed by die-cutting a web while reducing waste and periods of standstill.Type: GrantFiled: December 16, 2020Date of Patent: December 13, 2022Assignee: Heidelberger Druckmaschinen AGInventor: Werner Schwab

Patent number: 11507329Abstract: A method of producing printed products uses at least one computer and at least one input device for controlling at least one machine for processing printing substrates. The input device receives technical and economic data of at least one print shop and the computer receives customer preferences relating to print jobs by using the input device. Based on the technical and economic data of the print shop, the computer calculates a simulation of possible print jobs producible in the print shop. The computer takes into account the results of the simulation and the customer preference inputs and generates matching offers for print jobs. The computer compares the generated offers with customer print jobs and, if a match is found between an offer and a customer's print job, the print job is processed by the machine for processing printing substrates.Type: GrantFiled: January 28, 2021Date of Patent: November 22, 2022Assignee: Heidelberger Druckmaschinen AGInventors: Bernhard Wagensommer, Rainer Wolf, Frank Kropp, Gottfried Grasl, Dominic Stahl, Georg Roessler, Juergen Grimm
