Description

The invention relates to a method for adapting at least one cylinder elevator to a change of substrate in a printing press. This process is carried out in a printing machine. The printing material is provided within a printing operation in the printing units with a printed image, such that a spanned on a printing form cylinder printing plate is colored and transfer the resulting print image on the guided on a printing cylinder substrate while the printed image resulting from the current printing process Strains of the substrate is adjusted.

When in the field of processing of sheet-shaped substrate, for example, when printing on sheet-shaped substrate, d. H. a printing sheet, this substrate is processed by several processing steps in succession, the substrate is printed successively, for example by several printing units and / or coating units. In this case, for example, by a rolling out of the substrate in cylinder gaps and / or by a swelling of the substrate by liquids, such as constituents of printing inks and / or dampening solution to a deformation of the substrate. This may result in a deviation between the layers related to the substrate, at which the individual processing steps act on the substrate. In the case of, for example, multicolor and / or multi-page printing, register errors and / or registration errors can result. An exact match of a print image on the front and back of a printed substrate printed on both sides is called register (DIN 16500-2). Multi-color printing is called the Passer (DIN 16500-2), when individual print images of different colors are combined exactly to a picture. The equivalent of the register also uses the expression of the color register.

When printing on an exemplary sheet-fed press, coating material, for example printing ink, is transferred from a forme cylinder to a transfer cylinder and from the transfer cylinder to a printing material held by an impression cylinder. The geometric dimensions of the printed sheet change as a result of the printing ink and / or dampening solution and the pressure in the printing gap. The printing sheet is, for example, based on a transport direction of the printing substrate and / or a circumferential direction of the impression cylinder longer and / or initially at its trailing end in a transverse to the transport direction of the substrate oriented transverse direction and / or an axial direction of the impression cylinder wider. If the printing press consists of several printing units, this is done more or less pronounced, for example, in each printing unit, so that a printed image printed by subsequent printing units in the circumferential direction deforms, in particular shorter and / or appears narrower compared to the previously printed images. This effect can be designed differently for each of the printing units, for example, which results in a high probability of register errors and / or register errors.

By the EP 0 812 683 A1 is a sheet-fed press known in the form cylinder own individual drives, which are mechanically decoupled from a main drive. Its speed is tracked, for example, a speed of a main drive of the sheet-fed press.

By means of such individual drives, it is possible errors in the register and / or register, which are based on changes in length of the substrate to reduce or prevent by a difference between a peripheral speed of the cylinder elevator to a peripheral speed of the substrate is made selectively and thus, for example, extends a print image targeted or shortened transmission. For this purpose, for example, a speed ratio between a forme cylinder and an associated impression cylinder is varied, for example cyclically.

In the following, an example is shown in which in the relevant printing unit form cylinder and counter-pressure cylinder have substantially the same circumference. At circumferential lengths of the impression cylinder, which represent a multiple of the circumferential length of the forme cylinder, the angular velocity of the forme cylinder is correspondingly substantially larger by a corresponding integer factor than the angular velocity of the corresponding impression cylinder. For example, one is Angular velocity of a forme cylinder against an angular velocity of a transfer cylinder or at least one impression cylinder is reduced as long as a cylinder lift of the forme cylinder is in contact with the transfer cylinder and / or as long as the transfer cylinder is in contact with the substrate. As a result, a printed image is shown elongated on the substrate, for example, to counteract an elongation of the already applied to the substrate printed image by preceding cylinder column. Thereafter, the angular velocity of this forme cylinder relative to the angular velocity of the transfer cylinder or at least the impression cylinder is preferably increased for compensation, as long as the cylinder lift of this forme cylinder due to a cylinder channel of the forme cylinder and / or a cylinder channel of the transfer cylinder is not in contact with the transfer cylinder and / or as long the transfer cylinder is not in contact with the substrate due to the cylinder channel of the transfer cylinder and / or the position or shape of the impression cylinder. After a complete revolution, the relative angular position of the two cylinders is preferably identical again. As a result, in particular unintentional errors with respect to the printing lengths of the printed images of the individual printing inks can be compensated for in a targeted manner.

For example, in the case of forming cylinders having a circumference of a multiple of a section length of the substrate, one complete revolution of the forme cylinder may result in a multiple cycle of increased and reduced angular velocities, and thus a multiple capture of the original relative angular position.

In a change in a speed ratio between two adjacent cylinders, for example between a forme cylinder on the one hand and a transfer cylinder on the other hand or a transfer cylinder on the one hand and a counter-pressure cylinder on the other hand, it is necessary in any case that two directly adjacent cylinders rotate at times with different angular velocities and different peripheral speeds. Such adjacent cylinders usually have defined rolling surfaces, each rolling on each other and by a constant position of the axes of rotation of these cylinders is ensured to each other, especially in those situations in which a channel of one of these cylinders opposite to a lateral surface or a channel of another of these cylinders , As a result, vibrations are to be prevented by sudden force changes that would occur without these rolling surfaces at the beginning and at the end of a channel. Usually so-called bearer rings are used as these rolling surfaces. With changes in the speed ratio and thus mutually variable peripheral speeds, however, no more pure unwinding, but also a sliding contact between these rolling surfaces.

The object of the invention is therefore to provide a method for adjusting at least one cylinder elevator to a substrate change in a printing press, which allows a needs-based adjustment.

The specific data is z. B. by an operator of the printing press in the respective clamping elements 20 input and / or tracking control computer.

Even in the case of several persisting at their respective position, z. B. self-locking trained clamping elements 20 in various participating in the execution of the same print job form cylinder 07 the adjustment and / or tracking of the respective tension in at least one of the cylinder lifts 08 preferably taking into account at least part of the specific data described above.

In an advantageous embodiment, it is provided that system-inherent correction values resulting from the machine-specific data and / or from the specific data for the mounted cylinder lift 08 and / or from the specific ones Data for the print substrate to be printed in the upcoming print job and / or from the process-specific data to compensate for an expected change in substrate before processing the print job, ie in particular when setting up the printing machine for the upcoming print job, especially when setting the respective clamping elements 20 be considered and then during the execution of this print job the previously made setting of the respective z. B. by the clamping elements 20 applied tension is tracked in particular based on at least one variable process parameter or machine parameter.

A procedure for generating correction values, in particular with a consideration of first correction values when setting up the printing press and tracking the setting made during the execution of this print job, will now be described by way of example with reference to FIG 4 explained. There are schematically the printing cylinder of a printing unit 01 ; 02 ; 03 shown. Such a printing unit 01 ; 02 ; 03 In the area of a so-called printing unit superstructure, one in an embodiment for the offset printing method comprises a transfer cylinder 06 , z. B. as a blanket cylinder, running first printing cylinder. This is another, as a form cylinder 07 assigned executed printing cylinder. Furthermore, the printing unit includes 01 ; 02 ; 03 in the area of a so-called printing unit substructure as a printing cylinder 04 trained printing cylinder and one as a transfer drum 05 designated transfer drum. In the exemplary embodiment are or are the transfer drum 05 , the printing cylinder 04 and the first printing cylinder via a driven by a main drive motor not shown here coherent gear train 55 driven.

The further printing cylinder is assigned a position-adjustable drive. This is usually designed as a direct drive DA, d. H. the drive motor is connected coaxially fixed to the drive shaft of the further printing unit cylinder and there is no positive connection with the drive of other cylinders and / or rollers.

This position-adjustable drive is trackable to the first printing cylinder. This is done so that actual position values LW1 of the first printing cylinder are compared with actual position values LW2 of the further printing cylinder. As a result, position differences are determined whose values serve as the basis for the actuation of the position-adjustable drive. This creates a press-specific error that must be compensated.

This is done by determining values for a correction of the drive of the further printing unit cylinder from the position differences and a compensation curve not shown here. This means that the corrected value for the position-adjustable drive is determined. This is done in a control unit 56 ,

To the group of the above-mentioned press-specific errors include, for. B. caused by concentricity error of the first printing cylinder cylinder error. Printer-specific errors are also errors that z. B. by concentricity error of at least one provided for detecting the angle of rotation provided angular position encoder on the first printing cylinder. Furthermore, printing machine-specific errors occur when applying documents to the first printing cylinder. For example, such errors are inherent in the system.

These systematic, engine-specific errors are determined in the course of printing the press before it is delivered and / or in the course of setting up the press before a series of print jobs or before each print job and in the control unit 56 deposited. From these values, first angle-related correction values KW1 are generated, which are generated from the press-specific errors. These first correction values KW1 are now a subordinate overlay computer 57 in the form of first correction signals 58 transmitted and deposited there. The first correction values KW1 are now available for the control of the position-adjustable drive.

The means for determining the angle-related correction values further comprises a computing unit 59 for determining second angle-related correction values KW2. This arithmetic unit 59 Print job-specific errors are mediated as a basis for the calculation of the second correction values KW2.

For example, this register of print job-specific errors includes the register errors that occur as a result of the printing sheet being lengthened 31 arise. Through the loading of the printing sheet progressing from printing unit to printing unit 31 with color and moisture as it passes, it changes its dimension both in length and in width. The increase in length of the print sheet 31 can be compensated for example by the pressure length compensation already described. This is possible by targeted control of the position-adjustable drive. This is done by the other printing cylinder relative to the first printing cylinder in its peripheral speed is cyclically changed. That is, the other printing unit cylinder is driven faster compared to the first printing cylinder within each revolution, whereby a minimum slip between the lateral surfaces of both cylinders is generated. This will do that on the sheet 31 applied print image 32 also printed longer and thus increasing from printing unit to printing unit or from color to color length change of the sheet 31 compensated. After each revolution, the rotational speed is again set to the rotational speed of the first printing cylinder.

The measured values as a basis for this Drucklängenkomposition can z. B. can be determined as follows:
Like from the 4 can be seen has the print image 32 of the print sheet 31 at least two measurement points formed here as pass marks 42 on, which have been applied in the course of the exposure of the printing plate. These are in a direction indicated by an arrow transport direction of the sheet 31 in each case at the beginning of printing and at the printing ends of the printed image 32 arranged. It is also possible to arrange an additional third registration mark between these two registration marks.

The current print length can be determined in different ways. Currently still widely used is the manual determination of the print length. This is done by printing test sheets as part of the preparation of a print job, or by taking test sheets during a printing process. A test sheet is evaluated by manually checking the position of the registration marks arranged at the beginning of printing for each color and correcting any register deviations that may be present by machine, ie by controlling the printing press. Subsequently, another test sheet is printed or removed. Now the distances to the rear registration marks assigned to the print end are measured and the values of the arithmetic unit 59 transmitted. There, the different values for each color are determined.

If there are third pass marks not shown here, intermediate values can be obtained by measuring these pass marks. These intermediate values allow a statement about the course of the printing length in the transport direction of the printed sheet 31 , This makes it possible to change the printing length more targeted, ie the change in printing length can be selectively changed locally. Prerequisite is the use of suitable facilities, such as so-called actuators.

Another way to determine the printing length is, for example, by a z. B. trained as a camera detection device 60 z. B. an inspection system register deviations in the printed image 32 and to determine the print length from these register deviations. This can be done manually on test sheets as well as inline in the press.

Both the manual measurement of the registration marks and the automatically determined values are now in the arithmetic unit 59 to disposal. This makes it possible to determine the second correction values KW2.

As a result of the calculation of the second correction values KW2 are second correction signals 61 to the following overlay calculator 57 transmitted.

In the overlay calculator 57 the first correction values KW1 are superposed with the second correction values KW2. There are control signals 62 generated, which a drive control 63 the further printing cylinder can be taught.

The superposition of a first correction value KW1 with a second correction value KW2 can be carried out sequentially. That means that for a first rotation angle range, for example, the position-adjustable drive is given a first correction value KW1, the control signal 62 generated and the position-adjustable drive provided. After processing, the second correction value KW2 is specified for the following second rotation angle range, the control signal 62 generated and the position-adjustable drive provided. Subsequently, the first correction value KW1 is again predefined for the following third rotation angle range. This sequence continues until the circulation is completed at 360 °.

In a further refinement, the superposition of the first correction values KW1 with the second correction values KW2 is carried out simultaneously. In this case, a first correction value KW1 with a second correction value KW2 in the overlay computer 57 calculated and a control signal per rotation angle range 62 provided for the control of the position-adjustable drive.

The control computer of the processing machine, in particular the printing press, z. B. the previously described functions of the control unit 56 and / or the overlay calculator 57 and / or the arithmetic unit 59 and / or possibly also the drive control 63 to unify.

If a print job is processed, then it is preferred for each printing unit 01 ; 02 ; 03 the actual position of the respective on the respective cylinder lift 08 recorded printed image feature, in particular passport cross. For example, an operator removes after a trial print a substrate sheet, measures the relative position of the image features and passes these values to the control computer. Alternatively or additionally, this process is carried out by machine, in particular by means of corresponding sensors. For example, during the processing of the print job, the layers of the image features are recorded in fixed or at least definable intervals or continuously and transmitted to the control computer. In this way, even during the processing operation of the substrate, in particular in a running printing process of the printing machine continuously adjusting the position of the clamping elements 20 and / or a corresponding control and / or regulation of the rotational movement of the at least one forme cylinder involved in the printing process 07 be made.

By way of example, by means of the control computer, any deviations of the image features or register marks which may be present between one another and those of different printing units are preferably calculated 01 ; 02 ; 03 come. For example, including the preferred deposited, for each clamped cylinder lift 08 Specific data is preferably a required change in position of the corresponding clamping elements 20 of the respective printing unit 01 ; 02 ; 03 and / or a required corresponding control and / or regulation of the rotational movement of the forme cylinder 07 determined.

A change in the dimension of the substrate in the circumferential direction B becomes an alternative or in addition to a change in the dimension of the at least one cylinder elevator 08 in the circumferential direction B preferably by a correspondingly controlled and / or controlled rotational movement of the forme cylinder 07 compensated. Accordingly, or alternatively or in addition to the above-described change in the dimensions of the cylinder elevator 08 in particular with the help of the drive of the forme cylinder 08 a length compensation performed or is at least so feasible. The drive of the forme cylinder 07 In particular, this is preferably designed as a single drive, more preferably as a direct drive DA.

A ratio between a first angular velocity of the forme cylinder 07 and a second angular velocity of the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 Speed ratio is called, in particular speed ratio between form cylinder 07 and impression cylinder 04 , Preferably, the substrate is processed in such a way that, during the processing of the substrate, the speed ratio is selectively influenced and / or adjusted in such a way that it deviates from any integer ratio at least temporarily and preferably for the major part of the time of processing. Preferably, therefore, during the processing of the substrate, the speed ratio is not integer, at least temporarily, and preferably more than half the time. An integer ratio of two values is to be understood in particular as meaning a ratio of values corresponding to the value corresponding to the denominator of an integer in the mathematical sense when the value corresponding to the numerator is divided. Examples of integer ratios are therefore one to one, two to one, three to one, four to one, or the like. Processing of the substrate is preferably to be understood to mean a regular processing of the substrate, for example a printing process and / or a painting process and / or an embossing process and / or a punching process and / or a perforating process. A regular processing is preferably to be distinguished from a start-up phase of the operation and / or a termination phase of the operation and / or an interruption of the operation.

Processing of the substrate preferably takes place in such a way that this speed ratio is changed during the processing of the substrate, in particular therefore the ratio between the first angular velocity of the forme cylinder 07 and the second angular velocity of the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 , During this processing of the substrate, a relative acceleration, which is related to the angular speeds, preferably takes place between the forme cylinder 07 on the one hand and the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 on the other hand. Such an acceleration is preferably at least temporarily positive and / or at least temporarily negative. Particularly in the context of such an acceleration, a change in the speed ratio preferably takes place during this processing of the substrate, more preferably a periodic change in the speed ratio. A period, ie, in particular a smallest local and / or temporal interval, after which the periodic change repeats, is preferred after a respective full revolution or also after an integral fraction of a full revolution of the forme cylinder 07 reached. An integer fraction is a fraction that, when multiplied by an integer, becomes unity. However, it can also be provided that the angular velocity of a single cylinder, in particular of the forme cylinder 07 or the impression cylinder 04 within a respective, preferably constant revolution period, that is to say within a respective full revolution or even within a corresponding integral fraction of a full revolution of the forme cylinder 07 . is set variable, so that successive revolutions differ with respect to a respective course of the speed ratio to each other.

For example, the form cylinder 07 during a full revolution through 360 ° over at least a first angular range of at least 180 ° and preferably at least 270 ° with at least a first peripheral speed of the forme cylinder 07 which is larger than a first peripheral speed of the transport body guiding the substrate 04 , especially cylinders 04 or impression cylinder 04 , Then this form cylinder is preferred 07 over at least a relatively small second angular range with at least a second peripheral speed of the forme cylinder 07 which is smaller than a second peripheral speed of the transport body guiding the substrate 04 , especially cylinders 04 or impression cylinder 04 , In this way, the cylinder elevator rushes 08 of the forme cylinder 07 the substrate during the determined by the at least a first angular range largest part of its revolution ahead, whereby, for example, the printed image 32 shortened is transferred to the substrate. Following is the form cylinder 07 rotates relatively slowly, so that the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 the form cylinder 07 catching up again. For example, a transfer cylinder rotates 06 but preferably not necessarily with a peripheral speed which substantially corresponds to a transport speed of the substrate.

The forme cylinder is preferred 07 during a full revolution through 360 ° over the at least first angular range of at least 180 ° and preferably at least 270 ° with at least a first peripheral speed of the forme cylinder 07 which is smaller than a first peripheral speed of the transport body guiding the substrate 04 , especially cylinders 04 or impression cylinder 04 , Then this form cylinder is preferred 07 over at least a relatively small second angular range with at least a second peripheral speed of the forme cylinder 07 which is larger than a second peripheral speed of the transport body guiding the substrate 04 , especially cylinders 04 or impression cylinder 04 , In this way, the substrate rushes the forme cylinder 07 during the largest part of the revolution of the forme cylinder defined by the at least one first angular range 07 ahead, whereby, for example, the printed image 32 lengthwise transferred to the substrate. Following is the form cylinder 07 rotates relatively quickly, so that he the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 catching up again. The example arranged transfer cylinder 06 Also in this case, it preferably but not necessarily rotates at a peripheral speed which substantially corresponds to the transport speed of the substrate.

Preferably, a change in the speed ratio takes place by an acceleration of the forme cylinder 07 , Alternatively or additionally, the substrate carrying the substrate can also be used 04 , especially cylinders 04 or impression cylinder 04 be accelerated. However, preference is given to all transport bodies which guide the substrate 04 , especially cylinders 04 or impression cylinder 04 with a common main drive and / or gear train 55 connected to the processing machine, while preferably each form cylinder 07 driven independently of it. The form cylinder 07 So preferably has a drive, regardless of the drive of the forme cylinder 07 contacting transfer cylinder 06 and / or the inking unit 09 and / or the drive of the forme cylinder 07 contacting impression cylinder 04 is. Thus, the individual acceleration of the forme cylinder 07 to prefer.

For example, the form cylinder 07 and / or the cylinder lift 08 of the forme cylinder 07 with the substrate or the transfer cylinder 06 in contact while the first form cylinder 07 an angular position within the at least one first angular range holds. For example, the form cylinder 07 and the cylinder lift of the forme cylinder 08 out of contact with the substrate and the transfer cylinder 06 while the first form cylinder 07 an angular position within the at least one second angular range holds, in particular because of the forme cylinder 07 Oriented so that the cylinder channel 14 of the forme cylinder 07 in this at least a second angular range of the transfer cylinder 06 and / or the impression cylinder 04 and / or arranged opposite the substrate.

Processing of the substrate preferably takes place in such a way that, during the processing of the substrate, this speed ratio is changed at least twice, that is, for example, initially reduced and then increased again. Further preferably, a processing of the substrate takes place such that during the processing of the substrate, this speed ratio during each complete revolution of the forme cylinder 08 is changed at least twice, that is, for example, first reduced and then increased again. Further adjustments to corresponding changed circumstances are possible. This is the case, for example, when the forme cylinder 07 in the circumferential direction B with several cylinder lifts 08 one behind the other.

In other words, it is preferred during a complete revolution of the forme cylinder 07 to customize the outgoing print image 32 to the change in the dimension of the substrate and / or to compensate for the printing length by the drive of the forme cylinder 07 a difference angle between the forme cylinder 07 and the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 generated. The drive of the forme cylinder 07 is preferably controlled so that the difference angle between the forme cylinder 07 and the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 within a complete revolution of the forme cylinder 07 is brought from an initial value to a predetermined final value and brought back to the initial value. The control can also be done so that within a complete revolution of the forme cylinder 07 in several cycles the differential angle between the forme cylinder 07 and the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 is brought from an initial value to at least a predetermined end value and returned to the initial value.

For example, an elongation of the cylinder lift takes place 08 in the axial direction A and elongation of the cylinder elevator 08 in the direction of rotation B at least temporarily simultaneously. For example, a compensation of the printing length by the drive of the forme cylinder takes place 07 parallel to and / or at least temporarily simultaneously with at least one elongation of the cylinder elevator 08 in the axial direction A and / or at least one elongation of the cylinder elevator 08 in the circumferential direction B. In another embodiment variant is within the cylinder to be adapted to a substrate change cylinder 08 first the tensile stress in the axial direction A and then the tensile stress in the circumferential direction B of the respective forme cylinder 07 built up. The latter variant has the advantage that the required tensile stress in the axial direction A is substantially lower than if previously the tensile stress in the circumferential direction B has been applied. Because the application of the tensile stress in the circumferential direction B causes additional frictional forces, which impede the application of the tensile stress in the axial direction A. The latter variant thus leads to a higher accuracy when compensating for a change of substrate in a printing press.

In one embodiment, depending on the required adjustment, either an elongation of the cylinder elevator takes place optionally 08 in the circumferential direction B or a change in this speed ratio. As long as the necessary adjustment of the print image length in the circumferential direction B does not have a by a maximum elongation of the cylinder elevator 08 in the circumferential direction B achievable adjustment of the print image length, then takes place exclusively by means of the expansion in the circumferential direction B. For larger necessary adjustments in the circumferential direction B then takes place instead preferably only a change in this speed ratio. The decision is preferably made taking into account at least the preferably stored in the control computer, for the clamped cylinder elevator 08 specific data and / or at least one in particular for the clamped cylinder lift 08 specific limit. If the control value for moving the clamping elements 20 in the circumferential direction B exceeds this limit, instead, the drive of the forme cylinder 07 so controlled that within one revolution of the forme cylinder 07 a change in the speed ratio between the first angular velocity of the forme cylinder 07 and the second angular velocity of the substrate carrying the substrate 04 he follows.

In another embodiment, only one is effected by a maximum elongation of the cylinder elevator 08 in the circumferential direction B achievable adjustment of the print image length beyond necessary adjustment of the print image length in addition to this strain a corresponding change in this speed ratio. If the control value for moving the clamping elements 20 in the circumferential direction B exceeds this limit, in addition to an example, reaching to this limit shift of the clamping elements 20 the drive of the forme cylinder 07 so controlled that within one revolution of the forme cylinder 07 a change in the speed ratio between the first angular velocity of the forme cylinder 07 and the second angular velocity of the substrate carrying the substrate 04 , especially cylinders 04 or impression cylinder 04 he follows.

The stretching of the cylinder elevator 08 regardless of its direction both before and during the execution of a print job. In this case, a print job is to be understood as the entirety of the activities required for printing. That is, stretching can occur both before and during a color run. It may also be before or during a cleaning of the forme cylinder 07 or the inking unit 09 respectively. The stretching can also take place before or during the processing, in particular printing, ie before or during the contact of the transfer cylinder 06 or the cylinder elevator 08 with the substrate. If the stretching is to take place before the printing, the printing is preferably preceded by a previous proof, on the basis of which required control values manually or automatically, eg. B. can be determined by means of register measurements.

If the stretching takes place before the printing, then it is preferable for a contact of the forme cylinder taking place during the stretching 07 and / or the cylinder elevator 08 with a corresponding rotary body such as the transfer cylinder 06 or the impression cylinder 04 the inking rollers 10 and / or the dampening roller 13 not with that as a printing plate 08 trained cylinder lift 08 put on, for example, so that the color profile in the inking unit 09 preserved.

V. m. the direction of rotation arrows of the impression cylinder 04 is indicated, learns this sheet 31 Due to various printing process conditioned effects a deformation in its geometry, ie in its geometric dimensions. Under a sheet 31 Here is a sheet of paper or cardboard understood with a minimum format of DIN A3. Smaller format sizes are commonly referred to as "sheets." For example, such a printed sheet 31 in the printing process due to a pressure in each of him traversed printing nip between two cooperating printing cylinders of the sheet-fed press, z. B. in the nip between a transfer cylinder 06 and one with this transfer cylinder 06 cooperating impression cylinder 04 elongated.
