Description

  The present invention relates to a continuous paper printing system, and in particular, prints a plurality of marks representing information according to control of printing processing in a first printing apparatus arranged on the upstream side in the continuous paper conveyance direction, and conveys the continuous paper. The present invention relates to a continuous paper printing system that controls printing processing by reading each mark in a second printing apparatus arranged on the downstream side in the direction.

  In a continuous paper printing system that performs double-sided printing on continuous paper using a plurality of printing devices in a series, after printing on the surface of the continuous paper in the first printing device arranged upstream in the conveyance direction of the continuous paper In a continuous paper printing system that performs printing on the back surface in the second printing device arranged downstream in the continuous paper conveyance direction, the print data printed on the front surface and the print data printed on the back surface are inconsistent. Problems such as misalignment of the print start position and color misregistration of print data printed on the front and back surfaces.

  In order to solve these problems, conventionally, when the front side is printed by the first printing device arranged upstream in the conveyance direction of the continuous paper, an identification number indicating print information to be printed on the back side is printed on the back side. When the back side is printed by the second printing device arranged on the downstream side in the conveyance direction of the continuous paper, the above identification number is read, and if it is the corresponding identification number, printing is performed. If not, the printing is interrupted to eliminate the inconsistency between the print data printed on the front surface and the print data printed on the back surface (see, for example, Patent Document 1).

  Further, in a continuous paper duplex printing system using two single-sided printing devices, a page start position indicating a printing start position of the first surface in the first printing device disposed upstream in the transport direction of the continuous paper. A page start position mark and a page indicating the start position of printing on the second surface in the second printing apparatus which prints the mark and page number at a predetermined position on the first surface and is arranged on the downstream side in the conveyance direction of the continuous paper. After the number is printed at a predetermined position on the second side, the page start position mark printed on the first side and the second side is read by a pair of optical sensors arranged with the continuous paper interposed therebetween, and the page start on the front side If the difference between the position information of the position mark and the position information of the page start position mark on the back is within the threshold value, the printing is assumed to be normal. If the difference is outside the threshold value, the paper feed is stopped, and the same light Page by sensor Even if the read page number is different between the front and back sides, stopping the paper feed prevents the print start position from shifting between the front and back sides, and the print data mismatch between the front and back sides. (For example, refer to Patent Document 2).

  In addition, when a plurality of forms are printed on one page of printing paper in the continuous printing apparatus, the page information (for example, barcode) of the form to be printed on the front side is printed when the front side is printed on the first printing apparatus. ) Is printed on the printing paper, and when the back side is printed by the second printing apparatus, the page information of the form to be printed on the front side is read by the reading sensor, and based on the page information to be printed on the back side corresponding to the front side from the read information. Inconsistency between the print data printed on the front surface and the print data printed on the back surface is also eliminated by performing printing (see, for example, Patent Document 3).

  In the first printing apparatus, an alignment mark is printed on the leading edge of each page of continuous paper. In the second printing apparatus, the above-described alignment mark is read by a mark sensor, and from the read position to the transfer point. Obtained by dividing the distance by the web conveyance speed and the time obtained by dividing the distance from the exposure point of the photosensitive drum of the second printing apparatus to the transfer point by the rotational speed of the photosensitive drum. The deviation of the printing start position between the front surface and the back surface is also adjusted by controlling the web conveyance speed so that the difference between them is zero (see, for example, Patent Document 4 or 5).

Further, when a post-processing device is installed downstream of the printing device in the web conveyance direction, identification information indicating the content of the post-processing may be printed on the web by the first printing device. Since the mark and identification information are mixed and the above-mentioned mark sensor may misdetect the alignment mark and the identification information, there is a technology to prevent erroneous detection by setting a time during which only the alignment mark can be detected. (For example, refer to Patent Document 6), in order to prevent the above-described mark sensor from erroneously detecting the alignment mark and the identification information, a page for the operator to determine the position to print the alignment mark with the setting switch. By specifying the distance from the head, there is a technique for preventing the misalignment by preventing the alignment mark and the identification information from being mixed (see, for example, Patent Document 7). ).
Japanese Patent No. 3072139 JP 2001-287421 A JP 2004-268572 A JP 2004-233705 A JP 2005-29278 A JP 2002-187660 A JP 2005-205759 A

  However, the techniques disclosed in Patent Documents 1 to 5 do not depend on print data printed by a user when printing a plurality of marks for controlling print processing, which is an identification number, a page start position mark, and page information, on a print sheet. Since a mark or the like is automatically given as control information of the printing apparatus, in the case of a printing apparatus capable of printing the print data on the entire surface of the paper, there is a problem that the mark and the print data overlap each other.

FIG. 6 is a flowchart illustrating processing for controlling printing processing by reading each mark in the printing apparatus 144. FIG.

  First, in step 400, the paper information setting screen 600 (see FIG. 7) is called up and displayed on the user interface 68 of FIG. The paper information setting screen 600 includes a paper information selection unit 602. The paper information selection unit 602 is set so that the user can select the paper size of the continuous paper P, or a sensor or the like (not shown). The paper size of the continuous paper P read by is displayed, and the paper information setting screen 600 further includes a print control mark position information section 604 capable of designating the position for printing each of the aforementioned marks on the continuous paper P. When the paper information setting screen 600 is called, predetermined default values are displayed in the paper information selection unit 602 and the print control mark position information unit 604. After changing these default values, the change button 606 is pressed. In order to perform the printing process based on the value input on the paper information setting screen 600, the process proceeds to the next step 404, and the change button 606 is not pressed and is closed. If the button 608 is pressed, the process proceeds to the next step 416.

  Note that the mark types in the print control mark position information unit 604 include the above-described marks, that is, the TOF mark for adjusting the deviation of the print start position between the front surface and the back surface, print data printed on the front surface, and print data printed on the back surface. In the printing apparatus 144 shown in FIG. 1, the continuous paper P is printed after the continuous paper P is printed. When a post-processing device (not shown) that performs post-processing such as cutting is provided, there is a post-processing mark or the like that indicates a position for cutting in the post-processing device.

  Further, the upper left corner, lower left corner, upper right corner, and lower right corner of each page of continuous paper P are defined as starting points in the print control mark position information unit 604, and any one starting point can be selected. A value in a coordinate in which the right side in the width direction (see FIG. 8) perpendicular to the conveyance direction of the continuous paper P from the selected starting point is positive and the Y direction is the positive direction of the continuous paper P from the same starting point. By inputting, it is possible to designate the position where each mark is printed on the continuous paper P.

  Further, before pressing the change button 606, the print data stored in the storage unit 308 and each mark for which the print position is designated are merged and output to the user interface 68, whereby each mark, the print data, It is also possible to check in advance whether or not

  In the next step 402, it is determined whether or not the paper information regarding the continuous paper P or the position for printing each mark has been changed. In step 400, when the change button 606 is pressed on the paper information setting screen 600 shown in FIG. 7, it is determined that the paper information or the position information for printing each mark is changed. If the paper information or the position information for printing each mark is changed, the process proceeds to step 404. If the paper information and the information regarding the position for printing each mark are not changed, the process proceeds to step 416.

  In step 404, the paper information is changed by comparing the aforementioned default value for the paper information related to the continuous paper P with the value input to the paper information selection unit 602 of the paper information setting screen 600 shown in FIG. If there is a change in paper information, the process proceeds to step 406. If there is no change, the process proceeds to step 408.

  In step 406, the value input to the paper information selection unit 602 of the paper information setting screen 600 shown in FIG. 7 is stored in the RAM.

  Next, in step 408 of FIG. 5, the above-mentioned default value for the position information for printing each mark is compared with the value input to the print control mark position information section 604 of the paper information setting screen 600 shown in FIG. By determining whether or not there has been a change in the position information for printing each mark, if there has been a change in the position information for printing each mark, the process proceeds to step 410. Proceed to 412.

  In step 410, the value input to the print control mark position information portion 602 of the paper information setting screen 600 shown in FIG. 7 is stored in the RAM.

  Next, in step 412, it is determined whether or not the values input to the paper information selection unit 602 and the print control mark position information unit 604 of the paper information setting screen 600 are normal values. In this determination method, X is used to indicate the position from the starting point input to the print control mark position information unit 604, using predetermined values for the width and length of the sheet size input to the sheet information selection unit 602. If the values in the direction and the Y direction are within the predetermined value range, the input value is determined to be normal, and if the value is outside the predetermined value range, the input value is determined to be abnormal. If the input value is normal, the process proceeds to step 414. If the input value is abnormal, the process is repeated from step 402.

  In step 414, it is determined whether or not the change button 606 has been pressed in step 402, and information indicating that the paper information regarding the continuous paper P or the position information for printing each mark has been changed is stored in the RAM. After storing, the process proceeds to the next step 416 to determine whether or not a print process start button (not shown) has been pressed. If pressed, the process proceeds to step 418 and the print process end button (not shown) is pressed. If so, the printing process is terminated.

  In step 418, the paper information, the print output position of each mark, and the reading sensor position of each mark are set. Details of the setting process will be described with reference to the flowchart of FIG.

  First, in step 500, there is a change by reading this information from the RAM storing the paper information regarding the continuous paper P or the information indicating that the position for printing each mark has been changed in step 414 in FIG. It is determined whether or not. If there is a change, the process proceeds to step 502 in FIG. 6, and if there is no change, the process proceeds to step 510.

  In step 502, a paper information setting value and a setting value for a position for printing each mark are read. These setting values can be determined by reading the values stored in the RAM in step 406 of FIG. 5 and can be determined by reading the values stored in the RAM in step 410. It is possible to determine a set value for the position where the mark is printed.

  After reading these setting values, in step 504, the position for printing each mark is set in the printing apparatus 44 shown in FIG. Next, in step 506 in FIG. 6, the CCD 76, CCD 78, and CCD 80, which are sensors for reading the marks provided in the printing apparatus 144 shown in FIG. The position to be moved is moved based on the set value.

  After the movement is completed, in step 508, the printing process in the continuous paper printing system 10 in FIG. 1 is started to print the print data to be printed by the user.
