Description

The printing unit of 1359082 has a printing deviation caused by the correction of the printing deviation. However, since the influence of the correction of the printing deviation occurs on the printing unit of the subsequent stage with a predetermined time difference, the printing unit in which the printing deviation occurs by changing the same operation amount is disposed as shown in the patent document i. When the printing deviation is corrected by the driving speed of the printing unit on the rear side, the amount of expansion and contraction of the object to be stretched due to the correction of the printing deviation changes in accordance with the passage of time, and the printing unit and the rear side thereof on which the printing deviation occurs Between the printing units, it is unavoidable that new printing deviations occur, and there is a problem that is required in order to completely correct these printing deviations. Further, the subject matter disclosed in Patent Document 2 is a change in the tension of the printing substrate caused by the operation of the plate phase associated with the adjustment of the mark of the printing sheet of the preceding stage, and the corresponding mark error (plate phase) The calculation device of the communication model, for example, has a moment of inertia j according to a free roller disposed between the printing units of each segment, a path length between printing units of a certain segment and a lower segment thereof, and a lower length and a lower segment The calculation device for transmitting the model, such as the path length between the printing units, the speed of the printing substrate, and the conversion constant for the tension of the displacement, is disposed between the printing units, and the inertia moment j is appropriately set. The conversion constant of the tension or the like can be effectively prevented from affecting the printing unit on the downstream side when the printing deviation is corrected in a specific printing unit. However, since it is not clear how to set the conversion constant of the moment of inertia J tension, etc., it is possible to effectively prevent the influence of the correction of the printing deviation performed by the specific printing unit from affecting the printing unit of the rear stage side 2014-8393-PF 7 1359082 / The control device of the machine has a detection means for detecting a printing position of a printing plate of each printing unit on a to-be-printed object; and a correction means for the printing unit pair in the uppermost portion detected by the detecting means The print alignment hole of the printing unit attached to the printed matter and the printing plate hole of the printing unit on the rear side are detected as the printing deviation by the interval between the aligned marks of the printed matter, and the printing unit of the printing deviation is adjusted.胴 phase, and correcting the printing deviation; and compensating means for compensating the printing phase of the printing unit on the rear side of the printing unit that has performed the correction of the printing deviation, and the compensation means performs a control, which is • Correction means has adjusted the phase of the print phase, and the print phase compensation of the printing unit on the back side The adjustment direction and with the same direction and the degree of compensation should be reduced because the amount of phase after starting the elapsed time to compensate. [Effect of the Invention] According to the scope of the patent application! According to the invention, when the correction portion prints the deviation, the offset phase of the printing unit on the rear side is changed to the same direction and the same level of initial compensation as the correction direction of the printing deviation, thereby preventing the respective The tension of the printed matter between the printing units fluctuates according to the expansion and contraction of the printed matter, and the printing position of the printing unit on the front side can be made to be fixed by setting the substrate tension between the printing units constant. The printing positions of the printing units on the side are each correctly aligned. Further, 'the timing at which the portion printed by the correcting means immediately after the correction of the printing deviation reaches the printing unit on the rear side is compensated by the same phase of the printing direction of the printing sheet TL on the rear side. Because the substrate tension between the printing units is kept constant, the printing position of the specific unit and the printing position of the unit on the rear side of the unit can be correctly corrected. Therefore, it is possible to prevent the printing deviation caused by the correction of the printing deviation at the late stage 7C in the rear side unit, and to prevent the substrate tension from being changed by the re-compensation of the plate phase. The control of reducing the amount of phase compensation after recompensation suppresses the expansion and contraction of the object to be printed between the respective printing units, and has an advantage of effectively preventing the occurrence of printing variations. Further, according to the invention of claim 2, even if the path length of the substrate between the specific unit and the printing unit on the upstream side thereof is the same as that between the printing unit on the specific sheet and the rear side thereof When the length of the material path is different, the printed matter that has been stretched and contracted by adjusting the phase of the plate is moved from the specific unit to the rear side unit, thereby effectively preventing the amount of expansion and contraction of the printed matter from being changed. The advantage of the occurrence of printing deviations. According to the invention of claim 3, the initial compensation and the recompensated phase of the print phase are continuously reduced by corresponding to the amount of expansion and contraction of the printed matter which is changed after the correction of the correction by the correction means. In addition to this amount, there is an advantage that it is possible to reliably prevent the occurrence of printing variations caused by the change in the amount of expansion and contraction of the printed matter in response to the passage of time. According to the invention of claim 4 or 5, after the initial compensation and recompensation of the phase of the printing, it is not necessary to frequently change the phase compensation amount after the initial compensation and the recompensation. The complicated control can effectively prevent the occurrence of printing deviation caused by the change in the amount of expansion and contraction of the printed matter. According to the invention of the sixth aspect of the patent application, the dust core 12 of the structure 2014-8393-PF 11 1359082 is constructed, and the supply roller "and the discharge roller" for guiding the printing object 1 are disposed on the printing portion 13 The drive side motor that rotates the printing plate hole u is separately arranged; the long-term gp says 丨| + . A dryer 18 of 17 is disposed on the downstream side of the discharge roller 15. Between the discharge roller 15 and the dryer 丨 8, a marker sensor 19 for detecting the application on the printing unit 13 is provided. The printed matter: the application position of the ink, that is, the printing position, is determined by the detection and number of the hammer wheel detected by the 铋 mark. The correction means 21 provided in the control unit determines the printing units 5 to 7... 胴 llf. Whether or not the printing position of the printed matter 1 is sequentially changed is different. Specifically, the symbol sensor 19 detects the alignment of the second to fourth printing units 6 to 8 and the alignment of the U to the printed matter 1 , and. on the side of the 刖 & side of the third paragraph 3 The printing plate 5u of 5 to 7 is arranged at intervals of the alignment marks attached to the printed matter 1, and the correction means 21 compares the interval between the alignment marks and the μμ back ring and the preset base # interval (for example, 2) 0mm) 'The deviation between the interval and the reference interval of the 杳 杳 ^ 山 山 山 山 登 登 登 登 登 登 登 登 登 登 登 和 和 和 和 和 和 和 和 和 和 和 和 偏差 偏差 偏差 偏差 偏差 偏差 偏差 偏差 偏差In the case where it is determined that the deviation of the alignment mark in one of the second to the first is earlier than the predetermined value, the unit (the following is called the deviation of the mark,胴 兀 兀 的 的 的 * * * * * * 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动 驱动

2014-8393-PF 13 l359〇82 The compensation means 22' of the compensation plate phase corresponding to the brush unit (hereinafter referred to as the rear stage side unit) outputs a control signal indicating the adjustment direction and the adjustment amount of the plate phase. The compensation means 22 provided in the control unit 20 performs a control on the structure. When the correction means 21 is used to adjust the phase of the printing of the specific unit, the phase of the rear side unit is initially compensated to be the same as the adjustment direction. After the direction and the same degree, the phase compensation amount after the initial compensation is reduced in response to the passage of time, and the time at which the printed portion reaches the rear stage side unit after the correction of the printing deviation is corrected is used. The 胴 phase is compensated again in the same direction as the adjustment direction and the same degree 纟' reduces the phase compensation amount after the recompensation due to the passage of time. In terms of construction, the version of the latter stage is re-compensated with the version phase of the correction means 21 = the entire amount, and the quantity is set to be on the specific unit and the rear side of the corrected print deviation. A value corresponding to the length of the path to be printed between the units, for example, the path length between the special order 7L and the rear side unit (the length of the transport path), and between the printing unit of the specific unit and the front side The condition that the path length is equal 'set the recompensation amount to the same value as the initial compensation amount. In the construction, the compensation means 22 reduces the degree of reduction of the compensation amount at the start of the registration phase and the phase compensation amount after the re-compensation, based on the printed matter that occurs after the correction of the correction by the correction means 21 The change in the amount of expansion and contraction of 1 is set. In other words, as shown in Fig. 3, the mark sensor of the second printing unit 6 which is printed by the second color by the bank 2 (the detection signal outputted by the detecting means M9 is insulted in the second printing unit). 6 The printing deviation occurs, and the second printing unit 6 2014-8393-PF 14 1359082 is executed at this time. Then, it is determined that the printing deviation occurs in one of the second to fourth printing units 6 to 8 (specific unit). In the case where the correction means 2i performs the adjustment of the phase of the printing of the specific unit and corrects the control of the printing deviation, and at the same time compensates the phase initial of the rear side unit and the adjustment direction of the printing phase of the specific unit. After the same direction and the same degree, according to the pre-set compensation amount setting table or calculation data, etc., the compensation means 22 performs control for reducing the phase compensation amount after the initial compensation in response to the passage of time. For example, The detection signal output from the symbol sensor 19 of the second printing unit 6 that performs the printing of the second color on the printed matter i is determined to indicate the alignment symbol indicating the printing position of the first color and the printing position indicating the second color. row The interval between the marks is 21 mm, and the detection interval is only 1 mm larger than the reference interval set to 2 mm, that is, the printing of the second printing unit 6 is temporarily lowered by confirming that the second printing unit 6 is a specific unit. The rotation speed of the plate 胴u is not the same as the arrow number a in Fig. 3, and the phase of the stencil of the second printing unit 6 is shifted by only 1 mm in the opposite direction to the conveyance direction of the printed object i, and the phase of the plate is adjusted. Therefore, at the execution timing of correcting the control of the printing deviation, the substrate length (transport length of the printed matter) L12 between the first printing unit 5 and the second printing unit 6 is reduced by only 1 mm, and the printing deviation is corrected. Further, at the same time as the execution of the control for correcting the printing deviation, the rotation speed of the printing plate 11 of the third and fourth printing units 7 and 8 located on the subsequent stage side of the second printing unit 6 is temporarily lowered. 4 The printing plate (the rear side unit) 8 is in the form of the arrow X3 as shown in the arrow B and the fourth (b) of Fig. 3, and is displaced only in the opposite direction to the conveyance direction of the object 1 to be printed and 2014-8393-PF. 16 the value corresponding to the phase adjustment amount of the second printing unit 6 (1, and The fourth printing unit (the hole phase μ of the rear side unit is oriented toward the pepper of the printed matter 1; the military, the transport direction of the milk 1 is only displaced in the opposite direction to the value (lmm) corresponding to the initial compensation amount. According to the above, the substrate between the second printing unit 6 and the third printing unit 7 is performed by adjusting the printing phase of the second printing unit 6 to correct the execution timing of the printing deviation control. The long length L23' and the substrate length on the downstream side thereof are each reduced by only 1 mm of initial compensation (phase compensation). Therefore, prevention between the second printing ... and the third printing unit 7 and the third printing unit 7 and The tension ' between the printing soap elements 8' fluctuates due to the correction operation of the phase deviation of the second printing unit 6, and it is possible to prevent the printing variation from occurring due to the fluctuation of the tension.

As described above, after the initial compensation of the substrate length L23 between the second printing unit 6 and the third printing unit 7 and the substrate length on the downstream side is reduced by only km, the time (1) is obtained. According to the following formula (1) or the data of the exponential curve shown in the figure (4), the corresponding compensation amount is set; t table, etc., the phase compensation amount after the initial compensation is gradually reduced 'by this and in the correction means 21 correction (phase adjustment control of the second printing unit 6) corresponding to the change in the expansion and contraction of the printed matter i which occurs after the printing deviation, and the change of the printing phase Χ3 in the third printing unit 7 and the fourth printing unit 8 is performed, Χ4 control. In other words, by adjusting the hole phase of the second printing unit 6 at this time U and correcting the printing deviation, the substrate length L12 between the first printing unit 5 and the second printing unit 6 is expanded and contracted, and the amount of expansion and contraction is increased. A2 is represented by an exponential curve as shown in the following formula (1), for example, as shown in Fig. 4(a), depending on the passage between 2014-8393-PF 17 1359082. Further, in the following formula, X12 is the printing phase adjustment amount of the second printing unit 6 at the time t0, v is the conveying speed (m/s) of the printed matter 1, and S12 is in the first printing unit 5 and the second printing unit. The length of the path between the printing units 6. A2 = X12 · exp[—(V/S 12) · t] (1) The path length between the first printing unit 5 and the second printing unit 6 of the data A2' shown in Fig. 4(a) 2 The path length S12 between the printing unit 6 and the third printing unit 7 is set to 8333 mm, and the printing speed of the printing material of the ruthenium substrate (printed object 1) is 833.3 mm/s, in order to correct the second printing. In the case where the printing of the unit 6 is shifted, for example, the case where the length of the substrate of the object 1 to be printed between the first and second printing units 5 and 6 is shortened by 1 mm is adjusted, and the substrate is controlled. The state in which the amount of expansion and contraction A2 changes in accordance with the passage of time, etc., is known from the data A2, and the time t0' at which the control for correcting the printing deviation is performed is reduced by the adjustment operation in response to the phase of the plate in the first printing unit. 5, the base material_tension between the second printing unit 6 (the tension acting on the printed matter 1), and temporarily shortening the length L12 of the substrate by only 1 mm after shortening 'after the passage of time t, the shortening disappears ( cut back). Then, it is detected by the timer or the like that the correction means 2 1 corrects (adjusts the printing phase of the second printing unit 6) the printing portion after the printing deviation, that is, whether the printing portion that has been stretched by correcting the printing deviation reaches the third portion. The printing unit 7 confirms that the printing portion reaches the third printing unit 7 at the time t1' as shown in the fourth (b) and (c), and the hole of the third and fourth printing sheets το7, 8 The phases X3 and X4 are respectively compensated in the same direction as the adjustment direction of the plate phase set by the repairing device 2014-8393-PF 18 1359082, and the recompensation amounts R31 and R41 are set to and in the second printing unit. 6 and the value corresponding to the path length of the printed object i between the third and fourth printing units 7 and 8 on the rear side of the rear side, according to the preset compensation amount setting table or calculation data, etc., The passage of time is reduced by the control of the phase X3, X4 after the recompensation. For example, in the general printing machine in which the path lengths of the objects to be printed ι between the fourth printing units 5 to 8 are set to be equal intervals, the time t1 at the predetermined time set by the timer, and the initial compensation In the same manner, by temporarily lowering the number of revolutions of the printing plates 11 of the third and fourth printing units 7 and 8, the printing phase X3 of the printing plates 11 of the third and fourth printing units 7 and 8 is performed. The χ4 is re-compensated only by the values R31 and R41 (= X12) corresponding to the adjustment amount χΐ2 of the stencil phase of the second printing unit 6 in the same direction (refer to the arrow Β in Fig. 3). According to the above, as shown in FIGS. 4(b) and 4(c), at this point u, the execution will be between the second printing unit 6 and the third printing unit 7, and the third printing unit 7 and the fourth printing unit. The lengths of the substrates between the 8 are each reduced only, and after the "re-compensation of the job", the compensation means 22 performs control for gradually reducing the phase compensation amount by the time t elapsed from the time u. The re-execution at the time t1 After the compensation, the copyright phase χ3 of the third printing unit 7 and the printing phase Χ4' of the fourth printing unit 8 which are changed in response to the passage of time are expressed by the following equations (7) and (3). In the equations (2) and (3)' Α2 is the amount of change between the 丞i printing unit 5 and the second printing unit 6 obtained by the formula (1) and the length of the #+树, 丨θ1J blade coffin, and Α3 is in the sum ( 1)

(t-td23)]...(3 ι) In addition, the correction means 2 is detected by a timer or the like; [After the correction (adjustment of the printing phase of the second printing unit 6), the printing portion after the printing deviation reaches the fourth printing unit 8 is detected. At the time t2 that has arrived, the patch phase X4 of the fourth printing unit 8 is recompensated to the second re-compensation in the same direction as the adjustment direction of the patch phase set by the correction means 21 and The re-compensation amount R42 is set to a value corresponding to the path length of the object 1 to be printed between the third printing unit 7 and the fourth printing unit 8 on the rear side thereof, and is set according to the compensation amount setting table or calculation data. Etc., the control 2 is used to reduce the phase compensation amount after the recompensation. On the other hand, in response to the detection signal output from the symbol sensor 19 which performs the printing of the second color on the printed matter j (4) U (four) unit 6, it is determined that the alignment mark indicating the printing position of the S color and the second color are indicated. The interval of the alignment marks of the printing position is the melon, and the case is determined to be only 1 mm smaller than the reference interval (2〇_), and the transfer of the printing plate 胴u of the second printing unit 6 is improved. The length of the path between the first printing unit 5 I ^ 2 and the printing speed of the first printing unit 5 I ^ 罘 2 is shifted by only 1 mm in the direction of the printing of the second printing paste. The conveyance length of the printed matter 1 is only extended by 1 mm, and the control for correcting the printing deviation is performed. μ and the correction control of the printing deviation (the second printing sheet...the phase adjustment of the plate) is simultaneously entered into 2014-8393-PF 20 1359082 In the configuration, the correction means 21 determines that the printing deviation occurs in the printing position detected by the detecting means, adjusts the printing phase of the specific unit in which the printing deviation occurs, and corrects the printing deviation; and the compensation means 22, the compensation is located in the Repair of printing deviation The printing phase of the printing unit on the rear side of the positive printing unit is based on the construction, and at the timing when the correction means 2 1 adjusts the printing phase, the printing phase X3, X4 of the printing unit on the rear side is initially compensated into After the same direction and the same degree as the adjustment direction, the phase compensation amount after the initial compensation is reduced in response to the passage of time, and the portion printed after the correction of the printing deviation by the correction means 2 1 reaches the printing unit on the rear side. At the time of recompensating the printback phases X3 and X4 of the rear-end side unit in the same direction as the adjustment direction of the print phase set by the correction means 21, the compensation means 22 performs the re-compensation according to the passage of time. Since the subsequent phase compensation amount is controlled, when the printing deviation sequentially performed on the to-be-printed object 1 is corrected with a simple structure, it can be effectively prevented from affecting the rear-side unit. That is, as shown above, The detection signal output from the symbol sensor (detection means) 19 of the second printing unit 6 of the second printing unit confirms the timing t发生 at which the printing deviation occurs, and performs the adjustment. When the printing phase of the printing plate 11 of the second printing unit 6 in which the printing deviation occurs is corrected and the control of the printing deviation is corrected, the printed matter 1 located between the first printing unit 5 and the second printing unit 6 is the third. The dotted line of the figure is temporarily stretched, and the length L12 of the substrate changes, and the amount of expansion and contraction is gradually reduced in response to the passage of time. Thus, at the time t进行 at which the correction of the printing deviation is performed, the execution will be located in the second printing unit. 3rd, 4th printing unit 7, 6-8393-PF 22 1359082

The printing of 8 (4) U's hole phase Χ3, Χ4 is changed to be in the same direction as the correction direction of the printing deviation and the same degree of initial compensation is used to stop at the 2nd and 3rd brushes due to the expansion and contraction of the printed matter 1. The tension of the printed matter between the units 6, 7 and the third and fourth printing units 7 and 8 is changed, and the substrate tension between the printing units 6, 7 and 7, 8 is kept constant. Further, the printing position of the second printing unit 6 and the printing positions of the third and fourth printing units 7 and 8 can be correctly corrected, and "in response to the ith printing unit 5 and the second printing unit 6 The amount of expansion and contraction of the printed matter i gradually decreases with time, and the phase compensation amount after the initial compensation is reduced, whereby the substrate tension between the respective printing units 6, 7 and 7, 8 can be maintained. In addition, the printing unit 28 can effectively suppress the printing deviation. Further, after the correction means 21 corrects the printing deviation, the portion printed by the second printing unit 6, that is, the printing portion which is stretched and contracted in response to the correction of the printing deviation, reaches the rear side. At the time t1 of the third printing unit 7, the third printing unit 7 The 胴 phase χ 3 is compensated again in the same direction as the adjustment direction of the stencil phase set by the correction means 21 (see R31 in Fig. 4(b)), and the influence of the expansion and contraction corresponding to the correction of the printing deviation can be prevented. The printing unit 7 on the rear side can accurately prevent the printing position of the second printing unit 6 and the printing positions of the third and fourth printing units 7 and 8 so as to be effectively prevented on the rear side. The third printing unit 7 has a printing deviation caused by the correction of the printing deviation in the second printing unit 6. Further, the re-compensation operation of the third printing unit 7 is simultaneously as shown in Fig. 4(c). As shown, by rewriting the printing plate phase 4 of the fourth printing unit 8 to the same direction and the same degree as the third printing unit 7 2014-8393-ρρ 23 1359082, since it can be used in each printing unit 6, 7 Since the substrate tension between 7 and 8 is kept constant, it is possible to effectively prevent the fourth printing unit 8 on the rear side from being printed due to variations in the tension of the substrate. The portion printed by the second printing unit 6 immediately after the correction of the printing deviation At the time t1 of the third printing unit 7 on the rear side, when the re-compensation (R31, R41) of the plate phase is performed, the second printing unit 6, the third printing unit 7, and the third printing unit 7 and 4 - The substrate tension between the printing units 8 changes and the length of the substrate changes, as shown in the information A3 of Fig. 4(a), the printed matter i between the second printing unit 6 and the third printing unit 7 The telescopic expansion is temporarily performed in response to the recompensation (R31, R4i), and the expansion and contraction changes in response to the passage of time. Therefore, after the recompensation, the amount of expansion and contraction corresponding to the object to be printed is over time. Gradually, according to the compensation amount setting table or calculation capital (4) preset according to the formulas (2) and (3), the control of the phase compensation amount after reducing the recompensation is performed, even if the control phase is close to the direction of the origin Thereby, the (four) object 1 2 3 expansion and contraction between the second printing unit 6 and the third printing unit 7 and the third printing unit 7 and the 帛4 printing unit 8 is suppressed, and the printing deviation can be effectively prevented.隹, after the deviation, the portion printed by the second printing unit 6 At the time G of the fourth printing unit 8 of the last stage, the printing phase X4 of the printing unit 8 of 2014*8393-PF 24 1 is compensated to be in the same direction as the adjustment direction of the printing phase set by the correcting means 21 2 . The second time (see R42 in Fig. 4(4)), since the printing position of the second printing unit 1359082 and the printing position of the fourth printing unit 8 can be correctly matched, it is effective to prevent the last The fourth printing unit name of the segment has an advantage that the printing deviation caused by the correction of the printing deviation in the second printing unit 6 occurs. Further, when the portion printed by the second printing unit 6 reaches the fourth printing unit 8 at the last stage immediately after the correction of the printing deviation, the second re-compensation (R42) of the printing phase is performed, 3 The substrate tension between the printing unit 7 and the fourth printing unit 8 changes and the length of the substrate changes. As shown in the information A4 of Fig. 4(a), the third printing unit 7 and the fourth printing unit 8 are located. After the printed matter 1 temporarily stretches and contracts in response to the re-compensation, the amount of expansion and contraction changes in response to the passage of time t. Therefore, from the time u at which the second re-compensation is performed, the amount of expansion and contraction corresponding to the object 1 to be printed is gradually decreased as time t elapses, and the compensation amount setting table preset according to the equation (3) is set. Alternatively, by calculating the data or the like, the control of the phase compensation amount after the recompensation is reduced, thereby preventing the printed object 1 between the third printing unit 7 and the fourth printing unit 8 from expanding and contracting, and preventing the occurrence of the printing deviation. In addition, in this embodiment, a general printing machine in which the path lengths of the objects to be printed i between the second to fourth printing sheets 7G 5 to 8 are set to be equal intervals is described, and the correction means 21 is set. 2 The adjustment amount of the printing phase of the printing unit 6 and the recompensation amount when the hole phases X3 and X4 of the printing units 7 and 8 on the rear side are recompensated are set to the same value, but in the first to fourth printing units When the lengths of the paths i of the printed matter i between 5 and 8 are not all equally spaced, the recompensation amount is set to be the second printing unit 6 and the correction in which the printing deviation is changed.

The ratio of the path length 6 between the printed object 1 and the path length S22 of the third print 1 on the rear side corresponds to the first printing unit degree S12 on the front side and the second printing unit brush unit 7. The value of the printed matter is preferred. - for example, a special printing machine in which the path length between the second printing unit 6 and the third printing unit 7 is set to be twice the path length between the first printing unit 5 and the second printing unit 6, or by The printing machine of the downstream side of the second printing unit 6 is printed, and the length of the path on the downstream side of the second printing unit 6 is set to twice the upstream side, and the printing machine is omitted. The time set by the time 11 or the like is confirmed to be the time u at which the printing portion after the correction of the printing deviation reaches the third and fourth printing units 7 and 8, as shown in the fifth (b) and (c), The print phases X3 and X4 of the third and fourth printing units 7 and 8 are only compensated for the compensation (R3i, R4i) corresponding to a value (2 mm) which is set to 2 times the initial compensation amount of imm. The slave slave 22 is controlled in response to the gradual decrease in the amount of phase compensation due to the time " word. In the printing machine having the path length on the downstream side of the second printing unit 6 and the path length on the upstream side thereof as described above, the phase compensation amounts R31 and R41 at the time of recompensation are set to be different from the initial compensation amount. In the case of the value, the tension of the to-be-printed object i located on the upstream side of the third printing unit 7 is changed by the re-compensation, and the influence is transmitted to the downstream side, and the influence is applied to the second printing unit 6 and the The compensation amount of the plate phase X3 of the third printing unit 7 corresponding to the change in the substrate length L12 between the printing units 7 is set to the values shown by the following formulas (4) and (5). Further, in the equations (4) and (5)', the second print sheet 2014-8393-PF 26 of the second print sheet 2014-8393-PF 26 is corrected at the time t〇, and the correction amount of the stamp phase is S823. The path length between the printing unit 6 and the third printing unit 7, td23, at the time (1), immediately after the printing deviation is corrected, the portion printed by the first printing unit 6 reaches the third printing unit from the second printing sheet το6. 7 time until. In Fig. 5(a), A3 is affected by the recompensation, and the amount of change in the length L12 of the substrate which occurs between the second printing unit 6 and the third printing sheet το7 is expressed by the following expression: 〇). X3 = A2+B3 + X12... (4) B3=X12 - [(S23/S12)-l] · exp[-(V/S12) · (t-td23)]... (5) A3= X12 . [(S23/S12)] . exp[—(V/S12) . (t-td23)] (5.1) Further 'the length of the road between the second printing unit 6 and the third printing unit 7 S 2 3 is a special printing machine set to be 1/2 of the path length S12 between the first printing unit 5 and the second printing unit 6, or by printing the printing unit on the upstream side of the second printing unit 6 On the other hand, the path length S23 on the downstream side of the printing unit 5 of the 2014-8393-PF 27 1 is set to be 1 /2 on the upstream side, and after the predetermined time set by the timer or the like is passed, it is confirmed that the printing deviation is just corrected. At time t1 when the printing portion reaches the printing unit on the rear side, for example, as shown in FIGS. 6(b) and 6(c), the printing of the printing plates χ3 and χ4 of the third and second fourth printing units 7 and 8 is performed only. It is equivalent to the re-compensation (R31, 4 R41) of the value (〇·5 mm) which is 1/2 of the initial compensation amount (1 mm). Then, 'the compensation means 22 performs the 胴 phase 3 according to the compensation amount setting table or the calculation data preset according to the formula (4), (5) according to the elapsed time t from the time t丨. The control that the compensation amount of X4 is gradually reduced is better. In this case, B3 of the formula (4) is a value of the positive side (elongation direction) as shown in Fig. 6(a) 5 . 1359082, according to the above, the recompensation amounts R31 and R41 when the adjustment amount corresponding to the plate phase set by the correction means 21 is re-compensated, and the plate phases X3, X4 of the printing units 7, 8 on the rear side are compensated, It is advantageous to set a value corresponding to the path length S23 of the printed matter} between the second printing unit 6 having the t-printing deviation and the third and fourth printing units 7 and 8 on the rear side. Even in the case where the path length s 丨 2 of the substrate between the specific unit and the printing unit on the upstream side thereof is different from the path length S23 of the substrate between the printing unit on the specific unit and the rear side thereof, When the printed matter 1 that is stretched and contracted by adjusting the plate phase is transported to the printing units 7 and 8 by the second printing unit 6, it is possible to effectively prevent the printing deviation caused by the change in the amount of expansion and contraction of the printed matter. occur. In other words, when the path length S23 between the second printing unit 6 and the third printing unit 7 is large, the printing units 7 and 8 on the rear side significantly notice the printing due to the change in the amount of expansion and contraction of the printed matter i. In the case where the path length S23 between the second printing unit 6 and the third printing unit 7 is small, the change in the printing position of the printing units 7 and 8 on the rear side tends to be small. Therefore, the amount of expansion and contraction of the printed matter 1 can be effectively prevented by changing the re-compensation amounts R3 丨 and R41 when the stencils χ3 and Χ4 of the printing units 7 and 8 on the rear side are re-compensated accordingly. The occurrence of printing deviation caused by the change. Further, as shown in the above-described embodiment, the amount of expansion and contraction of the printed matter 1 that changes after the correction of the printing deviation is corrected, that is, the above equations (1) and 4(a), etc. The exponential curve shown corresponds, and the phase compensation amount of the initial compensation and recompensation of the phase X3 and X4 of the plate is connected.

2014-8393-PF 28 < S ^^082 When the third printing unit 7 is reached, the second printing sheet "...the recompensation, and according to the f 70 6 attached to the alignment mark and attached to the third printing list It is determined that the printing position is Xiao, and there is a possibility that the printing position is not correct. The reason is that the printing is added in the second printing unit 6: J is the third printing time. This recompensation is performed, and (4) whether the printing position is misaligned can be accurately determined in the detection interval of the alignment mark attached to the second printing unit 6 and the alignment correction mark added in the third phrase: On the other hand, in the printing machine in which the marking of the chasing pattern is aligned, the alignment of the printed matter 1 is based on the i-th printing unit 5 in the uppermost portion of the system, and the second to the rear side. Since the printing plates 胴n of the fourth printing units 6 to 8 are arranged at intervals of the alignment marks attached to the objects to be printed, it is determined that a printing deviation has occurred in the printing unit that matches the printing unit. Therefore, even if the second printing unit 6 detects that a printing deviation has occurred. The time t〇, due to the adjustment of the phase X2, In the case where a slight deviation occurs at the position of the alignment mark attached to the second printing unit 6, the arrangement is not affected, and the row attached to the printed object 1 by the first printing unit 5 in the uppermost portion of the system is aligned. The symbol ' can accurately determine whether or not the printing deviation occurs in the second to fourth printing units 6 to 8 on the rear side. Therefore, the determination of the printing position detected by the detecting means constituted by the symbol sensor 19 is as described above. When the printing deviation occurs in the second printing unit 6, at the time t0, as shown in Fig. 8, the printing phase X2 of the second printing unit 6 in which the printing deviation occurs is adjusted, and the printing deviation is corrected, and the rear side is corrected. The third phase and the fourth printing unit 7, 8 2014-8393-PF 31 1359082, the print phase initial compensation is compensated and the alignment direction is in the same direction and the same degree 'in the correction means 9 1 RA _ i π Λ - and the compensation hand 22 only perform the control of the phase compensation amount after the initial compensation amount is less than the time, thereby correcting the printing deviation sequentially performed on the object 1 by the early structure Can effectively prevent its shadow The advantages of the sound wave and the rear side unit.

For example, in the printing machine in which the marking pattern is aligned, it is assumed that the printing position detected by the detecting means constituted by the symbol sensor 19 determines that the printing offset 4 is generated in the 帛2 printing single force 6, and only The layout phase χ2 of the second printing unit 6 in which the printing deviation occurs is not adjusted, and the phase compensation of the third and fourth printing units 7 and 8 is not performed. The second to fourth printing units 6 to 4 are detected. In the experiment of the state of the printing deviation Υ2 to Υ4 which occurred in 8th, as shown in Fig. 9, it was confirmed that the third and fourth printing units 7 and 8 on the rear side had significant printing deviations γ3 and Υ4. Further, in the printing machine in which the marking of the monochrome type is aligned, the layout phase Χ2 of the second printing unit 6 in which the printing deviation is assumed to occur is adjusted, and the third and fourth printing units 7 and 8 on the rear side are adjusted. After the 胴 phase Χ3 and Χ4 are compensated in the same direction and the same degree as the adjustment direction, the compensated phase compensation amount is reduced in response to the passage of time, and is the same as the printing machine in which the tracking type is aligned. When the copyrights of the third and fourth printing units 7 and 8 are re-compensated at the predetermined time, as shown in FIG. 10, it is confirmed that the third and fourth printing units 7 and 8 on the rear side are sequentially A large printing deviation Υ3, Υ4 occurs. On the other hand, the print phase deviation of the second printing unit 6 in which the printing deviation occurs is adjusted as described above, and the printing deviation is corrected, and the rear side is corrected.
