Definitions
- the invention relates to a method for setting up a printing press according to the preamble of patent claim 1.
- the invention also relates to a mobile device according to the preamble of patent claim 11 and a system according to the preamble of patent claim 15.
- a printing press comprises a plurality of individual printing units (sometimes also referred to as “press units”), with each individual printing unit treating the material to be printed using a printing tool.
- printing tools can be, for example, flexographic printing plates, screen printing plates, offset printing plates, engraving cylinders, cold foil media, hot stamping media, punches, etc.
- the material to be printed is passed through the individual printing units one after the other.
- a paper web for example, it is transported through the printing units by means of suitable transport rollers, with each printing unit processing the printing web using its tool. In this way, several layers of color are usually applied one after the other to the material to be printed using respective printing units.
- the material to be printed can then be provided with finishes such as glossy or protective coatings in the respective printing units. It is then cut and/or punched into the required shape using our own printing units.
- finish such as glossy or protective coatings in the respective printing units. It is then cut and/or punched into the required shape using our own printing units.
- printed products such as packaging parts, labels, folding boxes, flexible packaging, etc.
- a makeready process may also be necessary within a single print job, for example if a printing tool has reached the end of its service life and/or an ink tank of a printing unit needs to be refilled (with the same ink).
- the process of “set-up” is understood to mean, in addition to the described physical work on the printing press, the selection of a specific tool and/or a specific color, in particular in combination with several print jobs.
- the object is specifically achieved by a method for setting up a printing press, wherein the printing press comprises a plurality of printing units, at least some of which are each equipped with a printing tool and/or an ink to complete a print job on the printing press.
- job information specific to the respective print job is provided, which indicates for each printing unit of the printing press which tool and/or which color it is to be equipped with, the job information comprising a unique tool information which is used to identify an individual physical printing tool.
- two similar printing tools can be available for a partial image of a print job, each of which is designed for a printing output of 30,000 linear meters.
- One of the printing tools has already been used for a print job of 17,000 linear meters, the other is unused.
- the already used printing tool can be efficiently used (and thus virtually used up), while for a print job of 25,000 linear meters, the choice should fall on the unused printing tool. Only if the respective printing tool is individually and clearly specified in the job information can the most suitable tool be selected.
- the prerequisite here is of course that the individual printing tools are individually marked, for example with a tool ID in the form [Tool image]-[Instance number], according to which, for example, the individual tool IDs "12345-01" and "12345-02" can be assigned for a similar tool image with the number 12345 and two tools with the instances 01 and 02.
- a tool image is therefore the entirety of all individual physical templates used to create a corresponding image, regardless of the actual physical instance of the template used to create the image. This identification or determination is preferably carried out, for example, by selecting the tool image and instance number.
- the job information is provided as a graphical representation and includes at least one machine-readable code that represents parts or the entirety of the job information.
- the job information can, for example, be in printed form and the machine-readable code can be designed as a data matrix code, bar code or QR code.
- the job information is provided as electronic machine-processable information.
- the job information can be provided, for example, as a file or bit sequence.
- the job information is recorded using a mobile device.

- the mobile device can be transported by the printing technician to his various work locations so that he can access the job information at any time.
- Other, similar mobile scanning and processing devices are also conceivable for other types of printing plates.
- the mobile device clearly identifies a respective printing unit and then outputs printing unit-specific information for the printing unit in question as to which printing tool and/or which color the printing unit is to be equipped with, the printing unit-specific information being based on the job information is formed.
- the printing unit-specific information is formed on the basis of the job information in such a way that the necessary information about the printing tool and/or color for the respective printing unit is read from the job information and combined to form the printing unit-specific information.
- the printing unit-specific information essentially forms a subset of the job information that applies to the respective printing unit.
- the printing unit-specific information also includes the information that individually identifies the printing tool (tool ID).
- the mobile device is set up to uniquely identify a respective printing unit.
- the identification can be carried out, for example, using an optically or electronically readable code applied to the printing unit (e.g. data matrix code, bar code, QR code, RFID code), which indicates the specific printing unit and which is read using the mobile device and evaluated to identify the printing unit becomes. Based on the job information, the mobile device then creates the printing unit-specific information.
- an optically or electronically readable code applied to the printing unit e.g. data matrix code, bar code, QR code, RFID code
- the job information is already provided in a form that represents the respective printing unit-specific information as such.
- the mobile device identifies the printing unit to be equipped (e.g. based on the applied code) and then selects the correct printing unit-specific information from the job information.
- the job information and/or the printing unit-specific information is transmitted from the printing press or the printing unit to the mobile device.
- the printing press must have communication options.
- a further advantageous embodiment of the method according to the invention provides that the mobile device detects an optically or electronically readable code of a printing tool and checks whether the printing tool corresponds to the Printing tool specific information corresponds to the printing tool and / or whether the printing tool has a condition that is sufficient to fulfill the print job, the unique tool information contained in the job information being used to carry out the test, and with the mobile device based on the test carried out optical or acoustic display is generated, which indicates whether the printing unit in question is to be equipped with the printing tool.
- the correct printing tool can be individually selected based on the tool ID contained in the job information and the printing unit-specific information.
- the aging condition of the printing tool is preferably also taken into account.
- the printing technician can, on the one hand, be shown the specific printing tool to be used (as well as possible available replacement tools in the event of damage) and, on the other hand, after selecting a printing tool, a confirmation can be given to him as to whether he has actually selected the correct printing tool. This further reduces the susceptibility to errors.
- the printing tool is recognized using a code that can be detected using the mobile device, e.g. a data matrix code, a bar code, a QR code or an RFID code, which is individually attached to the printing tool and which is compared with the tool ID.
- the printing unit-specific information includes information that indicates a current storage location of the printing tool to be used.
- the information can, for example, be presented in a format specified by the operator of the printing press (e.g. "shelf number - compartment number").
- a format specified by the operator of the printing press e.g. "shelf number - compartment number”
- any other format is also conceivable.
- a format that has a maximum of three dimensions is preferably used here (e.g. room number - shelf number - compartment number)
- storage location-specific information is recorded with the mobile device, on the basis of which the information contained in the printing unit-specific information about the Storage location of the printing tool is adjusted.
- the individual printing tool can be tracked with regard to its location by constantly tracking the storage location information stored for this printing tool to the current location of the printing tool. After removal from the storage location, the previous information can be overwritten with a note indicating current use of the printing tool. In addition, after the printing tool has been inserted into the corresponding printing unit, the information can indicate the specific printing unit. After the printing tool has been placed in a warehouse again, the information can be adjusted to the new storage location, which can correspond to the previous storage location, but does not have to.
- acknowledgment information is recorded with the mobile device, which indicates which printing tool and/or color the printing unit in question is currently using is equipped.
- the acknowledgment information can, for example, be saved or transferred to external systems.
- the method is carried out repeatedly for each printing unit to be loaded and release information is generated, if the acknowledgment information for each printing unit to be loaded matches the specification specified in the job information, with the printing press only starting to complete the print job if the release information is available.

- step S100 the computing device provides job information for a print job to be carried out, which indicates for each printing unit of the printing machine with which the print job is to be carried out which printing tool and/or which color it is to be equipped with, the job information includes a unique tool information (tool ID) that is used to identify an individual physical printing tool.
- tool ID unique tool information
- the job information can, for example, be printed out (cf. Figure 2 ) or provided as a saved file or bit sequence.
- step S101 the job information is transmitted to the mobile device. This can be done by scanning an optically readable code and/or data transfer of the stored file.
- an individual printing unit of the printing press is identified and selected using the mobile device. This can be done again by reading an optically readable code applied to the printing unit Detecting a signal from an RFID chip applied to the printing unit or by other suitable measures that allow a single one to be selected from the several printing units of the printing press.
- the mobile device After selecting and identifying the printing unit in question, in step S103 the mobile device generates printing unit-specific information based on the job information, which indicates which printing tool and/or color this particular printing unit is to be equipped with.
- the printing unit-specific information includes the individual tool ID, with which the printing tool can be clearly identified.
- the printing unit-specific information is output by the mobile device, for example displayed on the device's display. This allows the printing technician to easily identify which printing tool and/or color he has to use for this special printing unit.
- the setup process is divided into individual sub-processes that are processed sequentially for each printing unit to be loaded.
- the printing unit-specific information can also include information about the storage location of the printing tool to be used, for example information about a specific shelf and a compartment number. This makes it easier for the printing technician to find the appropriate printing tool.
- step S105 a code applied to a printing tool removed from the warehouse is scanned using the mobile device.
- a special feature here is that each individual printing tool has a unique tool ID. Even if two printing tools are designed to print the same image, they have different tool IDs to allow selection of a specific printing tool. This makes it possible in particular to select a printing tool that is also suitable for completing the printing job in terms of its aging status (running meters already completed, etc.) in order to avoid unnecessary changes during the printing job.
- step S106 the mobile device checks whether the tool ID scanned on the printing tool matches the tool ID contained in the printing unit-specific information. If there is no match, an error message is generated, prompting the print technician to select a different printing tool.
- the mobile device adjusts the information about the storage location of the selected printing tool in step S107 in such a way that the previous location is deleted and the printing tool is marked as “in transport”.
- This information can also be passed on to the computing device in step S108, provided that it includes a database with the storage location of all printing tools, so that the data base of the computing device can be updated.
- an ink required for the printing unit can be taken from an ink store.
- step S109 acknowledgment information is recorded with the mobile device, which indicates which printing tool and, if applicable, which color the printing unit in question is currently equipped with.
- the mobile device uses the acknowledgment information to check whether the correct printing tool and, if applicable, the correct color are actually present in the printing unit in question and issues a confirmation (or, if necessary, an error message).
- step S110 the storage location-specific information about the printing tool can be adjusted again so that it is marked as “installed in printing unit xyz”. This information can also be transmitted to the computing device to adapt the database (step S111).
- the mobile device generates release information in step 120, if this is present, the printing press can be started.
