Definitions

  • the invention relates to a method for quickly adjusting the inking unit of a printing press to the conditions required in the printing process by generating a defined ink layer thickness on the rollers of the inking unit, which in addition to the inking unit rollers includes an ink fountain, ink metering elements, an ink fountain roller and a lifting roller, with the aid of setting values which be taken by plate scanning, storing pre-orders or scanning a print template.
  • the printing process in a printing press essentially consists of transporting printing ink from a storage container via an inking unit to a printing form and generating a printing image from this printing form on a printing medium.
  • offset printing there is also the fact that the printing plate has to be moistened and the print image is transferred from the printing plate to the printing medium via a rubber blanket. Paper in the form of sheets or webs generally acts as the print medium.
  • a printing ink of relatively high viscosity has to be used. This is due to the fact that with the aid of only small ink layer thicknesses, sufficient surface coverage, ie a sufficient ink layer on the print carrier, is to be achieved in order to obtain an optically sufficient print image.
  • the offset printing inks contain very highly concentrated color pigments and, in order to be processable at all, must be used in a very tough state.
  • the high toughness of the printing ink plays a role in the distribution of the printing ink in the inking unit.
  • the design of the inking unit is also affected.
  • the formation of the state of equilibrium in the inking unit is additionally influenced by the relationship between printing and non-printing surfaces on the printing plate and where printing and non-printing surfaces are, ie how the subject of the printing plate is structured.
  • rubbing in the inking unit creates a layer of ink even where no printing points on the printing plate can be assigned.
  • the goal of the printer is to accelerate the establishment of the equilibrium state for production printing.
  • so-called spreading rollers are provided on conventional inking units, which are arranged above the first roller of the inking unit following the lifting roller. After filling the ink fountain with ink, the printer will apply a strip of ink to this spreading roller by "spreading" it with a spatula.
  • DE-OS 2 922 964 now describes a system for printing press preparation and control.
  • the presetting of the inking unit in procedure 5000 is described therein.
  • the aim here is to derive setting values for the inking unit of a printing press from known printing conditions.
  • the dampening unit settings, machine speed, duct rotation, lifting stroke, plate cylinder and applicator roller diameter and the area coverage of the printing plate are used as parameters. From this, the ink layer thickness required on the applicator roller and, depending on this, the position of the metering elements are determined.
  • the printing ink is also included in the calculation as a parameter.
  • the prerequisite for the calculation is that the inking unit is in a stable condition.
  • Control mechanisms which automate the operating sequence of such machines have been known for a long time in office offset printing machines.
  • the printing plate or the printing film is automatically drawn in, the inking unit and the dampening unit are switched on and the paper transport or printing process is initiated.
  • a control mechanism for an offset printing machine is described in DE-OS 2 637 071. It has a ratchet gear with a ratchet arrangement, with the aid of which the operating sequence from the plate feeder to the printing of the first sheet of paper is automated.
  • the feeding of the paper should be delayed until the plate has been pre-moistened and provided with sufficient ink via the inking unit and has produced a saturated print image on the rubber cylinder. Only then should the first sheet be printed and immediately show a good print image.
  • this device requires that a very short inking unit and a printing ink with a relatively low viscosity are used.
  • the requirement for a color profile is very low. This means that an even layer of ink is required across the width of the inking unit, which can be produced easily and quickly.
  • the invention is therefore based on the object of developing a method with which an inking unit of the type mentioned can be brought into an equilibrium state suitable for continued printing as quickly and easily as possible by generating defined ink layer thicknesses which take into account the ink consumption during printing.
  • the origin of the gradient in the ink layer thickness in the inking unit will now be examined again. It is determined by the relationships between the print color drawn off on the printing plate and the respective splitting states between the individual rollers. If a lot of printing ink is removed from the printing plate, there is a greater gradient than if only a little printing ink is removed. For example, with a fully covered printing area, printing ink is always drawn off the inking roller over the entire printing area. The removed printing ink has to be added continuously. However, it is necessary that a certain layer of ink is present on the inking roller before it comes into contact with the printing plate. The same ink layer thickness is necessary if only about 10% of the printing plate is covered with the printing area.
  • inking rollers W1 to W4 are each assigned to a printing plate D as a simplified inking unit.
  • the printing plate D is provided with a distribution V at printing points corresponding to 100% area coverage.
  • the pressure plate D is provided with a distribution V corresponding to 10% area coverage.
  • the case of poor color guidance is shown in FIG. 2.
  • On the printing plate D only 10% of the area of the printing ink is accepted, corresponding to the distribution V of the printing area. However, the same ink layer thickness of 5 ⁇ m is required at the printing points as in the case of 100% area coverage.
  • the overall ink layer is 8 ⁇ m.
  • the relationships shown each represent a state of equilibrium. This corresponds to the gradient GF in the production run. 4 and 5, the gradient GF is shown in dashed lines, in FIG. 6 it can be seen as a solid line which represents the gradient actually generated in the inking unit.
  • the width of the diagrams in the horizontal represents the layer thickness of the printing ink, the vertical direction indicates the position of the transport direction of the inking units, whereby the gradient is to be seen as a straight line.
  • the inertia of the inking unit plays a role in building up these gradients and transporting changes in the ink dosage.
  • the inking unit In order to save time for the production run, the inking unit should be brought as close as possible to the production run condition beforehand.
  • the basic ink layer thickness must be present on the application rollers and, on the other hand, the gradient must be achieved as soon as possible.
  • the importance of the invention is all the more larger, the greater the storage effect of an inking unit and the more emphasis is placed on the presetting of the inking unit. It is only necessary to apply the basic ink layer to the inking unit once, when the inking unit is completely free of color.
  • the introduction of the color gradient into the inking unit must, however, be carried out in principle before each start-up of the printing press, since the color gradient always breaks down when the printing process is interrupted.
  • the approach to the pressure drop is adjusted to different extents before the start of printing.
  • a simplified version of the method for presetting the inking unit is based on the fact that an ink layer which is uniformly thick transversely to the transport direction is distributed as quickly as possible in the inking unit.
  • the non-uniformity in the introduction of a quantity of ink determined by the feeling is eliminated here because the printing ink is supplied with the lifting roller starting from a uniform setting of the metering elements.
  • a gradient occurs within the layer thickness of the printing ink on the inking unit rollers as seen in the transport direction. This gradient is important for the later formation of the printing gradient and is therefore consciously accepted.
  • the gradient is expediently designed in such a way that it corresponds approximately to the mean of the gradients occurring in the production run. In some places, there will be too little ink in other places compared to the production status, but too much ink. So the balance can change fairly quickly on both sides adjust to the printing conditions and thus ensure good prints at an early stage.
  • the described procedure makes it possible to relieve the pressure on the printer, to bring the inking unit into a defined initial state for continued printing and to automate the entire process in parallel with other work. As a result, the time for filling the inking unit can be eliminated as a non-productive time and it is fully available to the printer for other work, for example for continued printing or readjusting the color profile.
  • the more refined version of the process makes it easier to get good prints.
  • the basic step corresponds to the simplified process by introducing a basic amount of printing ink into the inking unit.
  • the resulting gradient is reduced by an equalization process.
  • the inking unit runs for a defined time without ink supply and removal.
  • the resulting basic ink layer then corresponds to the amount of ink required in the production run on the inking rollers.
  • the equalization processes follow an e-function and can be considered complete after a certain time. The period of time must be optimized in relation to the distance from the ideal state and the consumption of operating time. While the ink layer is being evened out, the ink profile on the ink fountain roller can be adjusted over the width of the printing plate according to the ink requirements.
  • the use of this method is particularly advantageous if a device for scanning the printing plate or another printing template is used to set the inking unit in order to determine the color distribution in the inking unit required in the production run.
  • the machine With the chosen procedure, the machine can be brought into a condition from which the application of the measured profile quickly leads to good printing results. It is not necessary to first wait in the production run until sufficient printing ink has run in and the color gradient necessary for the printing process has built up.
  • the dampening solution distribution in the inking unit is also taken into account. The distribution of the printing ink and the distribution of the dampening solution run counter to one another. On the one hand, too little dampening solution can be distributed in the printing ink, on the other hand too much.
  • the color distribution must be modified so that the dampening solution distribution in the inking unit is compensated.
  • the setting of the control must be gained from empirical values both for the running-in of the printing ink, ie the amount of printing ink that is transported into the inking unit, and for the modification of the ink distribution in relation to the dampening. It can be matched to the respective printing plate and entered in a control table. It is then possible, depending on the type of printing plate, the printing ink and the subject, to automatically predetermine the automated running-in process and the adjustment of the gradient to the ink consumption in connection with the scanning of a print template.
  • FIG. 3 an inking unit from rollers W1 to W4 is shown schematically.
  • the associated printing plate D has a distribution V of the area coverage, as shown at the bottom of the inking unit.
  • V the distribution V
  • the printer when the printer is manually preset, the metering elements on the ink fountain are set. This creates a rough profile P of the ink layer thickness on the first roller W1 of the inking unit.
  • the printer In order to fill the inking unit faster, the printer manually puts an estimated amount of printing ink onto the roller W2, as a result of which an additional layer Z of printing ink reaches the inking unit. Layer Z partially overlaps with the machine feed Profile P.
  • FIG. 4A shows the slope at X1 in FIG. 3.
  • the gradient GF required in production printing which leads to a basic color layer A, is drawn in dashed lines.
  • the area between G1 and GF is hatched and represents the need B for printing ink, which must be fed to the inking unit until it is in equilibrium.
  • FIG. 4B shows the gradient G2 in the area of line X2 according to FIG. 3.
  • the gradient G2 is composed of a portion corresponding to the profile P and a further portion from the additional color layer Z.
  • the ink layer Z is assumed to be uniform in thickness, which does not correspond to reality.
  • the basic color layer A must be produced again, but now by removing the excess printing ink via the printing process.
  • FIG. 4C the gradient G3 is shown in the area of line X3 according to FIG. 3.
  • almost only printing ink is brought into the inking unit via the additional ink layer Z.
  • the gradient G3 is overall above the very low pressure gradient GF.
  • the distribution V of the area coverage on the printing plate D is measured.
  • the measurement corresponds to ink zones that can be set in the inking unit and is transferred to the inking unit control. If the printing plate D is clamped in the printing press, printing ink must be brought into the inking unit.
  • the transport of the printing ink from the ink fountain to the inking unit then takes place in the following manner according to the method of the invention: First, all ink zones are supplied with the same ink layer thickness via their corresponding ink metering elements, ie the ink metering elements are all moved to the same distance from the ink fountain roller. Then the speed of the ink fountain roller is set to a certain value.
  • the lifter roller is moved back and forth between the ink fountain roller and the first inking roller in the same cycle by a lifting movement at two machine revolutions. Depending on the speed of the machine, the lifter roller is always on the ink fountain roller for the same length. However, if the ink fountain roller rotates faster, the transferred ink stripe on the lifting roller becomes wider.
  • the lifting strip required for filling the inking unit results from empirical values and measurements of the amount of ink contained in the inking unit. Once the ink fountain roller speed has been set, the lifter roller is switched on for a certain number of lifter cycles and thus a certain amount of printing ink is transported into the inking unit.
  • the gradient ink layer thickness is established for this process sequence. Only an average is indicated here.
  • the basic ink quantity is distributed in the inking unit according to the gradient G4 by the filling process. However, this gradient G4 deviates from the gradient GF required in the production run for the state of equilibrium.
  • the gradient G4 corresponds to an averaging over the entire width of the inking unit. It represents an average of all the different gradients GF occurring in the production run for the individual ink zones. Partly there is excess ink U, partly ink requirement B in the hatched areas recognizable. In the waste phase, the transition from the gradient G4 from the default setting to the production pressure gradient GF will take place relatively quickly.
  • the gradient G4 can of course also be set such that the basic ink layer A is just reached on the inking rollers in accordance with G4 ', G4 ". Then, when the ink flow is adjusted for all ink zones from the same position, a defined amount of ink is available for printing at an early stage The adjustment then consists in the fact that zonal excess of ink or ink requirement compared to the printing gradient GF must be compensated for over the length of the entire inking unit in the waste paper phase, whereas with a central position, as indicated in FIG. 5, a color reserve for the formation of the printing gradient already exists GF is present.
  • the gradient GF should now be generated even more precisely.
  • a certain amount of color is controlled transported to the inking unit by the speed of the ink fountain roller, a number of lifting cycles and the running-in period.
  • a further equalization phase is interposed when the lifter roller is switched off, in that the inking unit is operated for a while without ink being removed.
  • this equalization phase it can be assumed that the printing ink is distributed throughout the inking unit into a uniformly thick ink layer, namely the basic ink layer A.
  • This basic color layer A of about 5 ⁇ m is required in any case on the application rollers.
  • the color profile P on the ink metering elements can then be set in accordance with the values of the distribution V of the area coverage measured on the printing plate D.
  • a running-in phase is switched on again, in that printing ink according to the color profile P is transported into the inking unit via a certain speed of the ink fountain roller, a certain number of lifting cycles and a certain running-in period.
  • This phase should last so long that the ink gradient GF between the ink fountain and the inking rollers that is present in the production run can largely occur on the rollers of the inking unit. If this is the case, the process will be seamless.
  • FIG. 6 shows the structure of the production pressure gradient GF according to this process sequence.
  • the base color layer A is generated from the gradient G5 in the equalization phase. It is then present in the entire inking unit.
  • the amount of ink is fed to the inking unit, from which the printing gradient GF is generated.
  • the machine is then ready to print and immediately delivers good sheets, since the inking unit is balanced.
  • the time between the introduction of the color profile P and the formation of the color gradient GF or the final equilibrium in the production run is saved. This also eliminates a certain amount of waste that would still have to be printed even if the simplified procedure for presetting was used.
  • an ink / fountain solution balance is established in the inking unit. This can now be dealt with during the running-in process by modifying the color profile P and resulting adaptation of the printing gradient GF.
  • the ink supply must in principle be increased, since there the inking is impeded by the dampening solution contained in the printing ink.
  • This dampening solution distribution in the inking unit depends on the subject, since in weakly covered areas a relatively large amount of dampening solution is naturally transported from the printing plate to the inking unit because the printing plate is heavily moistened there.
  • the ink-fountain solution balance also adjusts itself according to the amount of ink transported, since the printing ink absorbs different amounts of fountain solution depending on the amount transported. However, the more dampening solution penetrates into the printing ink, the more the inking of the printing plate is impeded.
  • a device for executing the described method could be integrated into the control of the printing press. It then uses the drives of the dosing elements, the ink fountain roller, the lifting roller and the inking rollers. All that is required is a control program in which these drives are matched to one another and switched on in a corresponding manner. To do this, memories must be available in the machine control system that work together with such a device for presetting. The measured values are distributed over the distribution V into the device the area coverage on the printing plate D and stored there as setting values for the dosing elements. At the beginning of the running-in process, the control brings the dosing elements to a predetermined distance from the ink fountain roller. In addition, the drive of the ink fountain roller is set to a certain speed.
  • the controller starts up the inking unit, but the inking rollers are not placed against the printing plate D.
  • the control switches the machine off again and on the one hand sets the drive of the ink fountain roller to the value required for introducing the color profile P and on the other hand guides the ink metering elements in accordance with those in the color profile P. contained color distribution after.
  • the sheet feed to the machine is still blocked, so that the inking of the inking unit is not disturbed by inadmissible ink take-off.
  • only two steps are switched on, namely the homogenization phase for producing the basic color layer A and the supply of the color profile P into the inking unit. After all of these processes have been completed, sheet travel is released and the machine can be started up.
