Description

  The present invention relates to a print job preparation and control system. The present invention further relates to a print job preparation and control method.

  Normally, a printing shop can use a plurality of printing machines. At that time, preparation and scheduling of a print job for new printing are performed as follows. First, the printer manually determines basic data that is not unique to a printing machine, such as a printing color, a printing format, a thickness or weight of a substrate, and a type of a new print job. The print engineer then prints a new print job for the pre-selected printing press that is specific to the printing press and depends on the print job, eg, a print mechanism assignment value, a rack mechanism assignment value, etc. Value, blower rail value, inking mechanism value, dampening mechanism value. After determining the basic data and preset values, a new print job for printing is preset for the pre-selected press, with further adjustment values depending on the object, for example ink, for preparing the print job. The position of the metering element is assigned. A print job preset or prepared for a preselected press is assigned to a specific press for its execution or scheduling, respectively. At that time, the type of the printing press can be changed according to the maximum load of the printing press at the printing shop at the time of scheduling. In the latter case, at least the preset value of the print job set corresponding to the existing data must be manually changed by the printer. Therefore, according to practice, a large number of print jobs are manually preset by the printer, in which case the preset values must be changed manually after scheduling in some cases. This is very time consuming.

  From Patent Document 1, in order to streamline the preparation of a print job, the values of a print job to be newly executed are compared with the values of a print job that has already been executed. As a result, a new execution is performed based on this comparison. It is already known to automate the preparation of a print job to be performed by using the values of an already executed print job for preparation. However, the technique of Patent Document 1 does not take into account the problem that the printer model can be changed when scheduling a print job after it has been preset and prepared.

  Further, from Patent Document 2, a printing press having at least one machine element that can be adjusted by an actuator has been known. It describes a printing press having at least one mechanical element adjustable by an actuator. This machine element adjustment should affect the quality of the printing performed by the printing press. For this purpose, the optical detection device detects its quality with a sensor directed at the printing surface and sends the data to the control device. This control device is coupled with an actuator of the machine element, which minimizes the difference between the target value and the actual value depending on the target / actual value difference between the predetermined quality of the print and the measured quality Can be adjusted as follows. This control is based on the fact that the print quality is detected globally by an optical detection device and the data is evaluated for disturbing influences on the print quality. In this regard, in relation to print quality control, in particular, the application of a tempering device and an obliquely adjustable plate cylinder, adjustment of the printing color viscosity value, change of the alignment mark spacing, and roller pressing force and ink dispensing device Consider adjustment in more detail.

  Furthermore, it is known to use a so-called sheet inspection system in a printing press. Here, the print data is obtained in the printing machine by the image photographing device and compared with the data obtained from the school completion printing. If an error is confirmed, the printed sheet or utility can be marked during the manufacturing process and / or excluded from the manufacturing process or subsequent processing process.

  Furthermore, during printing, the print quality is optimized by internal and external quality detection systems, in which individual markings on the sheet (e.g. register marks), measurement fields (e.g. print control stripes) and / or full print images are taken into account. It is known. These systems are connected to an evaluation / control device, which is connected to the control of the printing press. A target template is stored in the evaluation / control apparatus, and can be used for comparison with a printed image. Furthermore, known printing defects are stored (eg unwind stripe samples). This makes it possible to recognize specific quality problems. When the tolerance is exceeded by comparing the target value with the actual value, and when a specific quality failure is recognized, the control device causes the operating element that acts on a specific machine part of the assembly to be within the target value range. Adjusted to be transferred. The position of the control element for the school completion sheet can be stored and is therefore useful for repetitive jobs.

  Prior to the start of printing, the operating element is already preset for the printed image based on the previous stage data, or is optimized by the computer of the control station, or in a repetitive job, its last stored position is adjusted again.

In the current technology, when a known printing defect is assumed, an error must first be recognized. This is usually done visually, after which the press must be stopped, and then the appropriate machine parts must be aligned manually or at a control station. This is, for example, a roller adjustment with a set screw or a registration position adjustment with a machine control station in the case of a fitting error. These steps must be repeated many times if necessary. Accordingly, the preparation time becomes longer, and the start-up printing failure is accompanied.
European Patent Application Publication No. 1 466 734 (EP1 466 734A2) German Patent Application Publication No. 10 2005 012 913 (DE10 2005 012 913A1)

  In view of the circumstances as described above, an object of the present invention is to provide a new print job preparation and control system and a corresponding print job preparation and control method.

  A printing press having an operating element can be adjusted by various mechanical members that affect its print quality. The operating element is automatically positioned by the control device. The signal required for this is generated from an optical detection system with an attached evaluation unit. The optical detection system is installed on an external measurement table so that markings (eg register marks), measurement fields (eg control stripes) and the entire printed sheet can be detected. The evaluation unit and the control device are coupled to each other or are control components (eg in a control station).

  Due to the possibility of adjustments or corrections described above, printing defects are already minimized by pre-setting before printing starts, and during the printing process, manual operation is performed on the printing press in addition to the detection process for measured values on the printed sheet. It is reduced without being needed and even cleared. However, the measurement value detection on the printing sheet can also be performed in-line by measurement during the printing process in the printing press. In this regard, so-called inline density meters or inline inspection equipment are known. This results in a significant reduction in machine down time, thus improving productivity and reducing the resulting printing failure.

  It is useful to correlate detected printing faults with changes in the operating behavior of machine elements, as print quality monitoring by taking images of printed sheets cannot directly consider the behavior of the printing press during operation. .

  Therefore, according to the present invention, changes in the dynamic region of the printing mechanism are also taken into account. It is known that the form or size of an ink foam roller, dampening foam roller or blanket (rubber cloth) changes with the action of printing color, dampening water and detergent. This is because the rubber material used is soft or shrinks. As a result, the contact location or the contact stripe also changes due to the change in diameter, which affects the print quality. Thus, in order to control the operating elements that cooperate with these machine elements, the dimensions of the machine elements can be monitored in combination with the methods and apparatus described above.

  It is advantageous to detect in-line measurements such as roller diameter or cylinder diameter. In that case, the measured values can be used to automate optimal use conditions or to make partially automated adjustments. In this case, the attached stripes or contact stripes between the rollers or between the rollers and the rubber cloth cylinder / blanket cylinder are adjusted under all operating conditions acting from the outside. In combination with this, temperature compensation can be performed.

  Furthermore, it is preferable to develop a control strategy in which the operation signal from the image evaluation is balanced with the operation signal from the dynamic monitoring.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  The figure usually assumes an offset printing press that includes a plurality of printing mechanisms. Each printing mechanism has an inking mechanism and possibly a dampening mechanism. Each inking mechanism includes an ink injection tube, an ink injection roller and an ink dispensing element, mostly a ductor roller or film roller, a number of ink rollers and vibrator rollers, and an ink foam roller. Inking mechanisms with so-called anilox rollers, which are sometimes configured as short inking mechanisms, are also known. Further, if there is a dampening mechanism, this includes a dampening water injection roller, a dampening roller, and at least one dampening foam roller. The ink foam roller and the dampening foam roller are assigned to a plate cylinder on which the printing plate is placed. The plate cylinder is assigned to a blanket cylinder or rubber cylinder that transfers the color image from the printing plate onto a printing sheet held on the impression cylinder. The printing sheet passes through all the printing mechanisms and absorbs different partial images of the printed image with different colors. Furthermore, a drying device assigned to one or more printing mechanisms can also be provided.

  In the functional schematic diagram according to FIG. 1, the pre-stage data can be supplied via the evaluation / control device to the operating elements in the printing press, which can be used for ink dispensing, dampening and drying in the machine part or assembly. To affect process steps like Furthermore, data obtained from the completion sheet or print sheet of the optical detection unit is supplied to the production process by the operating element via the evaluation device / control device. Eventually, the print quality of the print sheet is affected in this way. This closes the control loop.

a) Pre-settings at the start of a print job A variety of customary pre-settings from previous data on individual color components of a multicolor printed image, such as ink dispensing elements, ink injection roller motor speed and ink injection roller The pre-setting of the dactor roller installation time in FIG. In addition, depending on the object, the so-called attachment of individual ink foam rollers and dampening foam rollers can be adapted to the printing plates, vibrator rollers and dampening water injection rollers. If necessary, all individual rollers of the inking mechanism and / or the dampening mechanism may be removed. Further, the ink flow switching may be automatically executed within the inking mechanism as necessary. Here, for a printing plate that is weak against ghosts, a so-called head weight adjustment can be selected, in which case the printing ink is applied mainly to the printing plate of the plate cylinder by the first ink form roller. In addition, the distribution parameters, i.e. the so-called distribution process, the distribution start, and the vibration of the ink foam roller are preset according to the subject matter. Distribution may be stopped if necessary. Another preset amount that affects the coloration is the so-called ductor roller cycle, which indicates how many times the ductor roller is installed on the ink injection roller for each ink revolution. Based on the pre-stage data, a standard preset format is automatically adjusted on the plate, or in the case of a slight surface coating, a specific adjustment for a small ink consumption.

b) Optimization during the printing process In the evaluation unit, a print image template consisting of data from the pre-printing stage (theoretical completion sheet) is used, for example a calculated, almost optimized printing sheet or actually scanned. It is memorized as a completed school completion sheet. These data serve as a reference for the actually produced printed sheet to be detected next. At that time, the following printing defects can be detected by the measurement technique. These faults can be recognized in the printed image and can be influenced during printing via operating elements in the machine member.
・ Unwinding stripe (marking in the color image caused by the shape of the printing mechanism)
・ Stripe due to mechanical collision ・ Groove stripe (caused by the groove path of a dampening foam roller containing more water)
・ Cord stripe (marking caused by dampening)
・ Ghost (repetition of phantom images)
・ 疵 (dirt from printing process)
・ Over coloring, under coloring ・ Various effects depending on speed (compensation)
・ Failure of roller unwinding, or failure of the supply stripe width between rollers due to shrinkage or wiping of the roller cover ・ Dirt (when wetness is too low)

  All of the above printing defects are detected by optical density measurements or sheet inspection systems. In the above printing defect, there is a problem of deviation (optical density, luminance) (excessive or insufficient) that can be demarcated from a predetermined target value in the printed image. Other recognizable and influenceable deviations are fit errors (errors in the position of the partial image on the print sheet) and print length changes (deviations in the length of the printed image due to the printing process).

  Additional detection of data in the printing press may be necessary in the context of dimensional or operational defects such as speed effects, roller unwinding defects, or attached stripe changes. In particular, measuring devices for machine speed, roller diameter, attached pressure, or attached stripe can be provided.

  Striping across the seat travel direction is a difficult problem. In order to relate this uniquely, it is necessary to store in the evaluation unit a striped sample that can be caused by the shape of the inking mechanism, dampening mechanism, printing mechanism, so-called unwinding. It should be taken into account that stripes and stripes due to mechanical collisions always appear at equal intervals on the leading edge of the sheet. Once the stripe has been recognized, the position of each form roller on the printing plate and / or vibrator rotor can be adjusted by a motor. Similarly, individual foam rollers may be completely removed from the plate. In some cases, intermediate rollers that help advance the ink stream and so-called lidar rollers that help store and homogenize the ink stream can also be aligned as long as they affect stripe formation.

  In the recognized groove stripe, the amount of dampening water is adapted by adapting the speed of the dampening water injection roller or by attaching a dampening water dispensing roller to the dampening water injection roller.

  The parameter adjustment is performed until the target value remains stable. Alternatively, a malfunction display at the machine control station is also possible. In this case, the operator is given a defined value for manually aligning the rollers for optimization in printing technology.

  So-called ghosts can be detected by typical density deviations. In the recognized ghost, important dispensing parameters, i.e. dispensing stroke, dispensing start-up, and ink foam roller vibration are preferentially adapted. Similarly, the inking mechanism is switched to the head weight switching state by switching the ink flow.

  So-called code stripes are recognized by a significant density difference in the printed image and the distance between the two maximum and / or minimum values across the sheet travel direction. By adapting the number of revolutions of the dampening water injection roller and / or dampening water temperature, the code stripes are removed or minimized.

  Recognized so-called scissors, if they are present from the center to the back of the printing plate or printed image, activate only for a limited period of time relative to the plate cylinder of the dampening foam roller depending on its position. Is done. Similarly, the bridge roller that can be installed between the ink foam roller and the dampening foam roller can be switched to “built-in”. In that case, it also sends dampening water into the inking mechanism, so that excess dampening water is removed from the inking mechanism so that the amount of dampening water in the inking mechanism does not increase beyond the permitted amount. For this purpose, the inking mechanism blower can be activated. It is also known to automatically place a so-called scraper in the form of a scraper blade that can be placed on a roller or a printing plate, by means of coordinates, by the dirt.

  In the case of uniform over-inking or under-inking in the printed image on the printing sheet in one or more printing mechanisms, instead of adjusting the ink dispensing element, the ink injection roller speed is increased and decreased and thus evenly Increasing or decreasing the ductor roller stripe width at the time of increased ink supply will reach the desired target state.

  In so-called dirt, a printing color appears on the non-printing surface of the printing plate, that is, on the area without the printed image. This process is usually due to too little supply of fountain solution. When the dirt is recognized, the amount of dampening water is increased by increasing the number of rotations of the dampening water injection roller or by expanding the distribution gap in the dampening mechanism by adjusting the position of the distribution roller. In the case where the stain is only on one side with respect to the printed image, the soaking of the dampening metering roller is adapted by changing the slanting posture of the dampening metering roller with respect to the adjacent dampening mechanism roller.

  Another recognizable and influential printing fault is a fit error. Fitting errors can be recognized by the corresponding markings and their deviations which are also on the printing plate and thus also on the printing sheet. When a deviation that can be detected on the measurement table by an off-line measuring method or even inline inside the press is confirmed, the corresponding registration adjustments are automatically activated, i.e. the circumference, side and / or diagonal registration. become. In this case, the relative position adjustment of the printing plate or the plate cylinder with respect to the printing sheet or the relative positioning of the printing sheet with respect to the printing mechanism is usually performed.

  For example, the perceived deviation of the printing length due to the printing sheet becoming longer due to the absorption of dampening water can be removed by driving correction in the plate cylinder. This is advantageously possible with a plate cylinder that is driven separately, for example by means of a unique drive motor, allowing a change in the relative peripheral speed to the machine speed of the plate cylinder.

  In order to continuously monitor the printing process, the printing sheet is continuously detected during printing, and the adjustment value is corrected as necessary.

  Printing quality monitoring by taking images of printed sheets does not take into account the behavior of the printing press during operation and over a longer operating time. Therefore, it is useful to correlate printing defects detected by the above behavior with various changes such as dimensional fluctuations, power fluctuations, and temperature fluctuations of machine elements caused by the operating behavior of the printing press.

  Therefore, printing defects due to changes in the dynamic region of the printing mechanism are also taken into account. It is known that the form or size of an ink foam roller, a dampening foam roller, or a blanket (rubber cloth) is unavoidably changed by the action of printing color, dampening water, and detergent that come into contact. In this case, the rubber material normally used here swells or shrinks. As a result, the contact location or the contact stripe changes as the diameter changes. This also affects the quality of the printing technology. Thus, in combination with the methods and apparatus already described, the machine element dimensions can be monitored in order to control the operating elements that cooperate with these machine elements. Furthermore, the above-described problems may occur in relation to temperature fluctuations in the printing press. To overcome these, temperature devices are known. However, the effects can also be dealt with by the machine element monitoring. Thus, the means described below should relate, inter alia, to overcoming the temperature course that impedes the function of the printing mechanism.

  Advantageously, in-line detection of measurements such as roller diameter or cylinder diameter. In that case, the measured values allow an automated or partially automated adjustment of the optimum use conditions. Here, the attached stripes or contact stripes between the rollers or between the rollers and the rubber cloth cylinder / blanket cylinder are adjusted under all operating conditions acting from the outside. In combination with this, temperature compensation can be performed. This embodiment of the device can be adjusted directly via a servomotor or can be configured to give the press operator an optimum adjustment hint, for example in the form of a correction value, by means of a visual display at the control station. Detection of changes in the diameter of a roller or rubber cloth cylinder / blanket cylinder should be carried out by groping or non-contacting, for example by laser measurement, ultrasonic measurement, or a measurement method that can be performed by a magnetic, inductive, capacitive or infrared sensor. Can do. In this regard, well-known methods and measuring devices are used which are suitable for scanning a roller or a corresponding surface of a rubber cloth cylinder / blanket cylinder.

  FIG. 2 shows a block circuit diagram of this method part. A measuring device is indicated by an arrow and assigned to a roller. The measuring device provides a measurement of the actual diameter of the roller at all times or at intervals during machine operation. This may be a rubber cloth cylinder / blanket cylinder as described above. The measured value is transmitted to the control device. The control device is also combined with a roller adjustment operating element. In this way, it is possible to always perform matching between the roller diameter assumed in relation to the adjustment value of the roller adjustment and the actually measured value. With a steadily increasing roller diameter, changing the roller adjustment will result in a stronger roller pressure that will result in worse print quality. Therefore, the control device can correct this error by a corresponding operation signal to the roller operation device by correspondingly increasing the roller interval. When the roller contracts, the roller interval is correspondingly reduced.

  The measuring method can be simplified by measuring only one roller. Since all rollers are treated in the same way, it can be assumed with great certainty that the modification method is similar or very similar. Thus, from the roller change, the change behavior of other rollers used in the same function can be inferred. Here all diameter ratios are taken into account.

  Thus, the measurement of the ink foam roller can be utilized by a corresponding computational model for detecting the diameter of other ink foam rollers, or even one or more damp foam rollers. As a result, only one measuring device is required in the inking mechanism or the dampening mechanism.

  The above description is also applicable to a rubber cloth cylinder / blanket cylinder. The cooperation between the plate cylinder and the impression cylinder can be controlled by a pressure drive. Here, the control device is semantically used in a manner similar to that detailed in connection with the inking mechanism roller or the dampening mechanism roller. As a result, it is possible to avoid the development that impedes the printing quality during the printing process due to the pressure between the rubber cloth cylinder / blanket cylinder and the plate cylinder or impression cylinder.

  Another possibility of avoiding the effect of disturbing the print quality is to link the machine elements with each other in a process-dependent adjustment via forces acting between the machine elements. In this regard, the forces can be detected with roller supports, cylinder bearings or support ring contacts. From the effects of the measured forces, changes in the contact stripe width can also be inferred. Therefore, the amplifying force should be reduced and the decreasing force should be post-corrected. That is, the corresponding correction value for maintaining the departure state is detected and introduced into the corresponding operation means. Similarly, the correction value can be displayed so that the operator can correct it.

  That is, according to the above means, it is possible to recognize and eliminate other defects in print quality due to unintended changes in the contact stripe width (attached stripe).

  According to FIG. 2, for example, in addition to the control process, a print image monitoring apparatus can be incorporated corresponding to FIG. Thereby, it is avoided that the operation signal generated as a result of the print image evaluation overlaps with the operation signal from the roller monitoring or the rubber cloth cylinder / blanket cylinder monitoring in a method that deteriorates when added. That is, the control device according to FIG. 2 can compare the operation signal proposed from the print image monitoring with that proposed by the diameter or force monitoring on the roller or rubber cloth cylinder / blanket cylinder. In this regard, one or a set of control strategies are stored in the control device, which takes into account how the print quality is affected by each detected value.

In this regard, it can be treated as follows.
• Adjustments can be made if both adjustment strategies are consistent.
-If both adjustment strategies have the same tendency but different operating values, the average value of both operating signals may be taken.
• If both adjustment strategies conflict with each other, one priority strategy may be selected, or an alternative strategy may be sought for the adjustment strategy found from print image evaluation.
If one or both of the adjustment schemes gives an operation signal outside the operating area, or if a sufficient adjustment scheme is not detected, warn the operator to check the functional capabilities of the printing press, its adjustments, and the machine elements involved Can be output.

  The above method can be used for belt machines and roller machines, and is suitable for both wet offset and anhydrous offset. The inking mechanism is conventionally provided with a plurality of ink rollers, as a flexo inking mechanism as an ink chamber blade with a screen roller, or as an anilox mechanism as an ink chamber blade, a screen roller or one or more ink foam rollers Can be formed.

It is a functional schematic diagram by a block circuit diagram. It is a functional schematic diagram of a control device.
