Definitions
- the invention relates to a multicolor rotary printing press - in which a printing form carrier is assigned to each of the colors to be transferred to the printing material, which carries a printing form and - which can be fastened to a mandrel or cylinder of a rotary printing press in order to transfer the printed image to printing material, the Rotary printing machine has register devices which determine the position of the printing forms with respect to one another.
- printing form support is to be understood to mean all possible cylinders, sleeves or even flexible mats which carry a printing form.
- gravure printing cylinders are traditionally used to hold a printing form, which are held by pins or bearing points.
- sleeves which are slipped over a cylinder, have recently been used.
- many different colors are used, so that the requirements for register accuracy play a major role here, but register accuracy also plays a role in others Areas and in the use of other printing processes hnt, as the positions of the printing form carrier be set before each other, and at the beginning of the printing process.
- This definition is made, for example Flexographic printing machines of the prior art by aligning the printing form - usually a printing sleeve or a sleeve - on a pin protruding in the radial direction beyond the circumferential surface of the printing cylinder.
- the pressure sleeve or the sleeve in turn has a recess in . which the pen fits relatively precisely. It is difficult for the machine operator to correctly align the sleeve. This activity is often referred to as pre-registration.
- the game between pen and recess leads to inaccuracies in the registration. This game increases significantly with the service life, in particular in the case of printing plate carriers of flexographic printing which are changed frequently. If printing forms slip during operation on the mandrels or cylinders on which they are seated, register errors can occur or increase during operation. Therefore, the object of the present invention is to improve the register accuracy. The task is solved in that
- the register devices comprise sensors which determine the positions of the printing form carriers in the printing press.
- These sensors can include markings, data carriers or the like provided specifically for this purpose in the following information carrier.
- the simplest form of an information carrier is a simple line-shaped marking.
- the sensors can also detect characteristic surface features of conventional printing form carriers that are not loaded with information carriers - such as the raised edge of a printing form used in fiexo printing.
- the positions of the printing forms can then be made accessible to a machine operator, for example via a suitable interface such as a display, a screen or a printer. This can make corrections to the positions of the printing forms to one another.
- a suitable interface such as a display, a screen or a printer.
- Make gear connections between the drive and the pressure cylinders or mandrels In the case of directly driven machines, which are first disclosed in Ca 12 23 150, such an adjustment can be made by the operator by correspondingly controlling the drives driving the respective mandrels or cylinders.
- a printing form carrier is known from DE 297 20 928 U1
- the printing form carrier is a sleeve
- the information carrier is a transponder chip
- the information stored on the chip is characteristic of the printing motif and relates to the printing sleeve itself (printing motif, color, age, etc.).
- Such information is also often printed on printing sleeves in the form of plain text or barcodes.
- Printing form carriers form a system with a rotary printing press according to the invention if the automatically readable information is suitable for determining the relative position of the printing form carrier on the dome or cylinder of a rotary printing press.
- information carriers can also be designed as simple markings on the circumference of the printing form carrier. Such markings can be indentations or colorations in the carrier material, which can be recognized with optical sensors.
- a metal strip anchored in the carrier material also fulfills that with a suitable electromagnetic Sensor can be recognized for the same purpose. Even such simple markings, if they are designed as lines or dots, provide a small amount of information when the printed image carrier rotates, but this is in principle used to determine the angular position in the circumferential direction (longitudinal register) and the axial position of the printing form carrier on the printing cylinder or mandrel ( Cross register) is sufficient.
- information carriers that are extended in the circumferential direction over larger areas of the circumferential surface are preferred.
- Such information carriers can be loaded with larger amounts of information, and it is possible that the sensor can record the exact position of the printing form over a large angular range of the rotation of the printing form around the main axis of inertia of the dome or cylinder. This additional information can benefit the quality of the longitudinal register. Visually recognizable markings can become dirty during printing until they can no longer be recognized by the sensors. Therefore, magnetically or electromagnetically readable information carriers such as magnetic tapes, transponder dipole chains, sequences of suitable metal structures etc. are to be preferred.
- a further increase in register quality is possible if, in addition to the position of the printing form carrier, the position of the printing material is also recorded and used for registration. This can be done with the methods known from the prior art, in which the printing material is provided with register marks, the position of which is recorded by sensors. To study these procedures, reference is again made to the as yet unpublished application filed with the German Patent and Trademark Office with the file number 102 54 836.6-27.
- FIG. 1 shows a diagram of a printing form carrier according to the invention
- Fig. 2 shows a diagram of a printing form carrier according to the prior art
- FIG. 1 schematically shows the arrangement of an exemplary embodiment of a printing form carrier 1 according to the invention with an information carrier 2.
- This exemplary embodiment is an idiosyncratically shaped magnetic strip 2 which is embedded in the printing form carrier 1.
- tape-shaped magnetic strips are preferred.
- the sensor 3 is attached to a suitable location on the printing press, not shown. It 3 is suitable for reading the magnetic strip 2.
- the sensor 3 transmits an analog signal via the signal line 6 to the control device 7 of the printing press, which undergoes the signal in an analog-to-digital conversion and takes into account the information contained in the generation of register correction signals to the drives of the printing press.
- the greatest benefit of this exemplary embodiment lies in the simplification of the pre-registration, which is carried out according to the prior art as described above with the aid of a pen.
- the information read out by the sensor 3 can also be used to improve the registration during the ongoing printing process.
- the printing form carrier 1 is a sleeve which is mounted on the printing cylinder 5 of the printing press during printing operation.
- Such arrangements are Known in fiexo printing, but have also recently been used in gravure printing.
- the sleeve or the printing form carrier carries the printing form 6.
- the information carrier is arranged between an edge of the printing form 6 and an end edge of the sleeve 1.
- the arrow 4 indicates the direction of rotation of the cylinder 5.
- Figure 2 shows a printing form carrier 1 according to the prior art, which is provided with a recess 7.
- the printing form carrier is designed as a sleeve which is pulled onto the cylinder 5. When mounting, the machine operator must ensure that the recess 7 receives the register pin 8 of the cylinder 5, which protrudes beyond the circumferential surface of the cylinder in the radial direction. This is the only way to ensure satisfactory pre-registration according to the state of the art.
