Output unit is connected.

Then, the CPU of the computer 5 executes the document creation application based on the user operation to generate envelope creation data for causing the printing device 1 and the encapsulation / sealing device 2 to create an envelope. Then, by executing the printer driver, the envelope creation job generated based on the envelope creation data is transmitted to the printing device 1 via the network 4.

The printing device 1 prints on the printing paper of the contents based on the image data (or character data) included in the envelope creation job generated by the computer 5. As shown in FIG. 1, the printing device 1 prints contents from a plurality of paper feed trays (P1 to P3) provided inside or on the side surface of the housing 10 and a plurality of paper feed trays (P1 to P3). It has an introduction path 11 for taking out the paper and a loop-shaped transfer path 12 for conveying the printing paper from the introduction path 11. A plurality of types of paper (printing paper having different permeability) are stored in the plurality of paper feed trays (P1 to P3).

Further, the printing device 1 includes a print execution unit 13, a first discharge path 14, a second discharge path 15, a switchback path 16, and a control unit 17.

The print execution unit 13 ejects inks of each color of black (K), cyan (C), magenta (M), and yellow (Y) to the envelope and the paper of the contents conveyed by the transfer path 12. 4 It consists of two inkjet heads K, C, M and Y.

The first discharge path 14 discharges the printed paper to the sealing / sealing device 2.

The second discharge path 15 does not discharge the printed paper to the sealing / sealing device 2, but discharges the printed paper on the printing device 1 side.

The switchback path 16 receives the printed paper that has been conveyed through the transfer path 12, and then reverses the paper so that the front and back sides of the sheet are reversed and returned to the transfer path 12.

The control unit 17 controls the operation of each component included in the printing device 1 and the sealing / sealing device 2.

The sealing / sealing device 2 is a device that receives the printed contents sent from the first discharge path 14 of the printing device 1 and folds the contents into envelope paper to seal and seal the contents. More specifically, the encapsulation and sealing device 2 has a transport path 21 for transporting the contents extending diagonally downward from the first discharge path 14 of the printing device 1 and a transport path 22 for transporting the envelope.

As a result, the printed contents and the envelope with the window are conveyed from the first discharge path 14 to the transfer path 21 and the transfer path 22, respectively.

Further, the envelope sealing device 2 includes an envelope supply unit 24 that sequentially supplies envelopes with windows to the transport path 22, and a content supply unit that sequentially supplies blank contents (envelopes) to the transport path 21. 23 is also provided. The envelope with a window can also be manually supplied to the envelope supply unit 24, and is conveyed from the envelope supply unit 24 to the transfer path 22. The contents (encapsulation) of the blank paper can be manually supplied to the contents supply unit 23, and are conveyed from the contents supply unit 23 to the transfer path 21.

Further, the encapsulation and sealing device 2 is sealed with an encapsulation and sealing unit 25 that folds the contents transported in each of the transport paths 21 and 22 and encloses them in the transported envelope, and seals the envelope in which the contents are sealed. It is provided with a storage unit 26 in which an envelope (seal) is discharged and stored. Although not shown, the sealing / sealing device 2 is provided with an adhesive device for adhering (sealing) envelope paper, a transporting means for transporting the sealed seal to the storage unit 26, and the like, in addition to the above components. ..

FIG. 2 is a block diagram showing a configuration of a computer 5 included in the image forming system 100 according to the embodiment of the present invention.

As shown in FIG. 2, the computer 5 includes a CPU 51, a memory 52 such as a RAM, a program storage unit 53 such as a ROM in which various programs for operating the CPU 51 are stored, and each paper feed tray (P1 to P3). ), The hard disk 54 for storing the paper setting information such as the type information of the paper placed in), and the network connection unit 55.

The network connection unit 55 establishes communication with the printing device 1 via the network 4, and transmits the generated envelope creation job to the printing device 1.

By the way, in order to suppress the strike-through of specific information such as the address, this printing device inserts a blank page on the next page of the address page when the total number of pages of the contents is odd, and when the total number of pages is even, the address is addressed. The overlap between the print area of the page and the print area of the next page is determined, and if there is an overlap, the print setting is changed.

Therefore, the CPU 51 is set to function as the determination means 51a, the page insertion means 51b, the intra-regional determination means 51c, and the setting changing means 51d as described later by executing the program stored in the program storage unit 53. There is.

The determination means 51a determines whether or not the total number of pages of the specific page and the content page is an odd number based on the image data included in the envelope creation job. Here, the number of pages is not the number of sheets of paper, but the number of pages of image data. For example, in the case of double-sided printing, the image data of the first page is printed on the front surface of the paper, and the image data of the second page is printed on the back surface of the front cover. The specific page is a page on which specific information is printed, and here, the page is a cover page on which destination information (address and destination address) is printed as specific information.

<When the total number of pages is odd>
If double-sided printing is performed when the total number of pages is odd, one page becomes a blank page (a blank page on which no image is printed).

Therefore, when the determination means 51a determines that the total number of pages is an odd number, the page insertion means 51b inserts a blank page on the back surface of the specific page.

As a result, since the back surface of the specific page becomes a blank page, the image on the back surface does not show through in the area where the destination information is printed, so that the visibility of the destination information is improved. Further, even if the content information on the back surface contains confidential information, the confidentiality of the content information is improved because there is no strike-through.

<When the total number of pages is even>
When the determination means 51a determines that the total number of pages is an even number, the in-area determination means 51c puts the content information printed on the content page corresponding to the back surface of the specific page within a predetermined area including the specific information. Determine if it exists.

FIG. 3 is a diagram showing a flow of creating a sealed letter in the sealed sealing device 2.

As shown in FIG. 3, the windowed envelope paper F is provided with a window portion F1. The window portion F1 is made of a transparent film or the like so that the enclosed contents can be visually recognized.

A specific page G1 is printed on the surface of the content G. The specific page G1 includes destination information G11 including an address and a destination address.

The content page G2 is printed on the back surface of the content G. The content page G2 includes content information G21 such as a form.

If the content information G21 is in the predetermined area G12 including the destination information G11, the visibility of the destination information G11 may be lowered or the confidentiality of the content information G21 may be lowered due to strike-through. If the information G21 is not within the predetermined area G12, there is no possibility of strike-through. The predetermined area G12 coincides with the area of the window portion F1 of the envelope F.

Therefore, when the determination means 51a determines that the total number of pages is an even number, the in-region determination means 51c determines whether or not the content information G21 overlaps with the predetermined region G12 including the destination information G11.

In the example shown in FIG. 3, since the content information G21 does not overlap with the predetermined area G12, it is determined that the content information G21 is not within the predetermined area G12, printing is executed as it is, and the content G is folded by the sealing and sealing portion 25. The content G3 is created. The windowed envelope F that has been transported along the transport path 22 is folded by the sealed sealing portion 25 to contain the contents G3 (in the state of F2), and is glued to create a sealed letter F3.

On the other hand, when it is determined that the content information G21 overlaps with the predetermined area G12, the setting changing means 51d (FIG. 2) prints the content page corresponding to the back surface of the specific page, which is difficult to strike through based on the user setting. Change to settings or paper settings.

Here, the print setting that is difficult to strike through is, for example, a setting that moves or reduces the content information G21 so that the content information G21 is outside the predetermined area G12. Further, the amount of ink ejected when printing the content information G21 may be reduced to reduce the density. Further, the ink color of the content information G21 may be changed to an ink such as Y (yellow) that is inconspicuous even if it strikes through, or the composite K (black) may be changed to K (black). If Gy (gray) ink is installed, K (black) may be changed to Gy (gray).

The paper setting that is difficult to strike through is a setting that changes from a plurality of paper feed trays (P1 to P3) to paper that is difficult to strike through, that is, has low ink permeability. For example, change plain paper to matte paper.

FIG. 4A is a diagram showing reception of image data when the total number of pages is an odd number, and FIG. 4B is a diagram showing a printing order when the total number of pages is an odd number. is there. FIG. 4C is a diagram showing reception of image data when the total number of pages is an even number, and FIG. 4D is a diagram showing a printing order when the total number of pages is an even number. is there.

As shown in FIG. 4A, the total number of pages is "5". The image data 101 is a specific page on which the destination information is printed. The other four pages of image data 102 to 105 are content pages.

When the image data 101 to 105 of all five pages, which is one copy, is received, they are overlapped by face-up, so that printing is performed in the reverse order of the data reception order as shown in FIG. 4 (b).

In the example shown in FIG. 4B, since the total number of pages is an odd number, a blank page B is inserted between the image data 101 and the image data 102.

As a result, the image data 101, which is a specific page, is printed on the front surface of the first sheet, but since the blank page B is inserted on the back surface of the first sheet, the destination information is printed in the area. Since the image on the back side does not show through, the visibility of the destination information is improved and the confidentiality of the content information is improved.

In the example shown in FIG. 4 (c), the total number of pages is "6", which is an even number. The image data 201 becomes a specific page on which the destination information is printed. The other five pages of image data 202 to 206 are content pages.

When the image data 2001-206 of all 6 pages, which is one copy, is received, they are overlapped by face-up. Therefore, as shown in FIG. 4D, printing is performed in the reverse order of the data reception order.

In the example shown in FIG. 4D, since the total number of pages is even and the content information G21 overlaps with the predetermined area G12, the user can use the image data 202 corresponding to the back surface of the image data 201 which is a specific page. Based on the setting, the print setting is changed so that it is difficult to strike through, or the paper used for printing the image data 202 is changed to the paper that is hard to strike through.

As a result, the image data 201, which is a specific page, is printed on the front surface of the first sheet, but the image data 202 is printed on the back surface of the first sheet with a print setting that does not easily strike through. Since the image data 202 is printed on a paper that is hard to strike through, the visibility of the destination information is improved and the confidentiality of the content information is improved.

FIG. 5 is a flowchart showing the processing contents of the computer 5 included in the image forming system 100 according to the embodiment of the present invention.

Step S101: The determination means 51a determines whether or not the generated envelope creation job is a job that requires double-sided printing. If it is determined that the printing is not double-sided printing (step S101; NO), there is no strike-through, so the process ends.

Step S103: The determination means 51a determines whether or not the total number of pages is odd.

Step S105: When it is determined that the total number of pages is an odd number (step S103; YES), the page inserting means 51b inserts a blank page on the back surface of the specific page.

Step S107: When it is determined that the total number of pages is an even number (step S103; NO), the in-region determination means 51c corresponds to whether or not there is an image behind the window, that is, the back surface of the specific page. It is determined whether or not the content information printed on the content page is within a predetermined area including the destination information.

If it is determined that there is no image on the back of the window (step S107; NO), there is no strike-through, so the process ends.

Step S109: When it is determined that there is an image behind the window portion (step S107; YES), the page insertion means 51b determines whether or not the number of enclosed sheets is less than the maximum number of sheets. The maximum number of sheets to be enclosed is the maximum number of sheets of paper that can be enclosed in an envelope with a window, and is predetermined by the type of the envelope with a window, the type of paper, and the like.

Step S111: When the number of sheets is less than the maximum number of sheets (step S109; YES), the setting changing means 51d is set to insert a blank page for one sheet of paper (blank page for two pages on the front side and the back side) according to the user setting. Determine if it has been done.

Step S113: When the user is set to insert a blank page for one sheet of paper (step S111; YES), the setting changing means 51d is the next page of the specific data of the image data and the next page. Insert a blank page in.

As a result, the number of sheets to be printed is increased by one, but since a blank page is inserted on the back side of the specific page, the image on the back side may be shown through in the area where the destination information is printed. Since there is no such information, the visibility of the destination information is improved and the confidentiality of the content information is improved. The blank paper added at the time of printing may be supplied from the paper feed trays (P1 to P3) or may be supplied from the content supply unit 23.

Step S115: When the maximum number of sheets to be enclosed has been reached (step S109; NO), or when the setting for inserting a blank page for one sheet of paper has not been made (step S111; NO), the setting changing means 51d may be other. Determine if user settings have been made.

Step S117: When the change of the print setting is requested by the user setting (step S115; change of the print setting), the setting change means 51d strikes through the content page corresponding to the back side of the specific page based on the user setting. Change to print settings that are difficult to do.

Step S119: When the change of the paper setting is requested by the user setting (step S115; change of the paper setting), the setting changing means 51d strikes through the content page corresponding to the back side of the specific page based on the user setting. Change to a paper setting that is difficult to do.

If the user has not been set (step S115; no change), it is presumed that the user is aware of the risk of strike-through and wants to print without changing the setting. Therefore, the setting changing means 51d is used. , Ends the process without changing the print settings and paper settings.

Although the image forming system 100 including the computer 5 which is a control device connected to the printing device 1 and the sealing / sealing device 2 has been described as an example, the booklet printing is performed not limited to the sealing / sealing device 2. It may be a post-processing device. In this case, since the specific page is, for example, a cover page on which the title of the booklet is printed, it is possible to reduce the strike-through of the area where the title is printed.

Further, the CPU 51 of the computer 5 functions as the determination means 51a, the page insertion means 51b, the in-region determination means 51c, and the setting changing means 51d, but the CPU 51 included in the printing device 1 is not limited to this, and the determination means 51a and the page It may function as the insertion means 51b, the in-region determination means 51c, and the setting changing means 51d.
