  The operation of the printing system configured as described above will be described. The flowcharts shown in FIGS. 8 and 9 proceed under the control of the central processing unit 39 of the control unit 37 of the host computer 31.

  As shown in the flowchart of FIG. 8, in the host computer 31, a target print operation time span is input for each print line 11 by a keyboard 35 operated by an operator or an administrator (hereinafter referred to as an operator). Is set in the storage unit (S1). As shown in FIG. 7, the input time span data is a time span colored in a strip shape (for example, light blue) on the upper side of the display area 361 on the graphs L <b> 1 to L <b> 3 for each print line 11 of the display 34. Represented as display 362. The horizontal axis of the display area 361 represents time. Therefore, the operator can confirm the target time of work required for printing a predetermined number of sheets in each print line 11 by using the time span display 362, for example.

  Next, the printing operation is started (S2), that is, printing on the printing sheet 17 is started. During printing, data from the detection device 41 is collected and analyzed by the host computer (S3). Then, as shown in FIG. 7, the analysis result is displayed as a graph on the display 34 (S4).

  That is, in the display area 361 for each print line 11, the print job display 363 is serialized as time passes so that the time span display 362 is arranged vertically below the time span display 362. The color is expressed in various time series. The print job display 363 is colored differently for each print job. For example, the print operation 364 is green, the setup 365 is yellow, the cleaning operation 366 is dark, the stop 367 is red, and the power down 368 is gray. Is displayed. Therefore, the operator or the administrator can compare the executed print job with the time span display 362 and can appropriately grasp the operation status of the print line 11.

  The above operation is continued, and counting is executed (S6) as the printing operation ends (S5). For example, the number of times of the printing operation, setup, cleaning operation, stop, power-down, etc., the total time of each print job, the printing speed, the number of printed sheets, etc. are aggregated and stored in the storage unit 38. Therefore, the operation results for each printing span can be calculated and stored at this stage. Then, the calculation result is processed, and the processed data is recorded in a predetermined format (S7), for example, graphed and displayed on a display or printed out.

In addition, the operation results for a predetermined period can be aggregated or screened to be displayed as a monthly report for each month or a weekly report for each week.
Further, as shown in FIG. 9, during operation of the printing press 12 (S11), a printed pattern and a check mark are photographed and the data is input to the host computer 31 (S12). Then, data such as a print pattern representing an original image stored in advance and the captured data are compared, and the state of the print pattern and the positional relationship between the check mark and the secondary print pattern are determined (S13). That is, when the positional relationship between the check mark and the secondary printing pattern is shifted, it means that the positional relationship between the primary printing pattern and the secondary printing pattern is shifted. For this reason, the cause of the positional relationship deviation, the deviation amount, and the like are analyzed (S14), and the analysis results are totaled (S15). Then, the totaled result is stored in the storage unit 38 or graphed and displayed (S16). Here, the quality of printing can be determined according to the amount of deviation, and the yield can also be recognized. By accumulating these data, the state of the printing press can be recognized.

  During the printing operation, the same content as that displayed on the display 34 of the host computer 31 is displayed on the tablet 36. Therefore, by holding the tablet 36, the operator can confirm the operation status at a position where the operation and confirmation are easy, such as near the printing press 12, and is useful for improving the efficiency of the operation.
