In the image forming apparatus 10 of the image output system 1 of the present embodiment, as shown in
In the present embodiment, post-processing is to include the stapling process, paper folding processing and cutting processing.
The post-processing apparatus 30 includes paper output trays 30A, 30B and 30C so as to allow paper output in a sorting manner in accordance with a completed state of printed matter which is output.
Printed matter which is not subjected to post-processing is output to the paper output tray 30A. Printed matter which is subjected to the stapling process and not subjected to a saddle stitch folding is output to the paper output tray 30B. Printed matter which is subjected to the saddle stitch folding after the stapling process is output to the paper output tray 30C.
Next, description will be given specifically for conveyance of printed matter according to post-processing in the post-processing apparatus 30 of the present embodiment with reference to drawings.
First, description will be given for a case where post-processing is not set to printed matter.
The printed matter conveyed from the image forming apparatus 10 side to the post-processing apparatus 30 is, as shown in
Next, description will be given for a case where the stapling process is set to printed matter.
Printed matter which is conveyed from the image forming apparatus side is, as shown in
When the saddle stitching process is set to the printed matter, the stapling process is applied to a center part of the printed matter.
Then, the printed matter subjected to the stapling process by the stapler 351, when the saddle stitch folding is not set, is conveyed by conveyance rollers 333 and 334 and discharged to the paper delivery tray 30B by paper delivery rollers 342.
On the other hand, when the saddle stitch folding is set, the printed matter subjected to the stapling process by the stapler 351 is returned by the conveyance rollers 333 and 334, guided to a third sheet conveyance path 313 by conveyance rollers 335, and conveyed to a folding processing unit 360.
The fold processing unit 360 is configured by including a fold processing tray 30E, a folding member 361 and folding rollers 362 as shown in
A reference sign P indicates a plurality of pieces of printed matter reserved in the fold processing tray 30E.
The fold processing tray 30E is configured so that a plurality of sheets of the printed matter which are conveyed are able to be reserved.
The folding member 361 and the folding roller 362 are arranged at positions in which the holding member and the folding rollers are facing across the fold processing tray 30E.
The folding rollers 362 are configured by a pair of rollers. The folding member 361 is configured so as to be able to project toward between rollers of the folding rollers 362 (a nip position).
The printed matter conveyed to the folding processing unit 360, as shown in
The printed matter is then conveyed onto a cutting tray 30F by conveyance rollers 336 and 337 and positioned by a positioning portion 371, and one end side of the printed matter is subjected to a fore edge cutting by a trimmer cutter 372 at a predetermined position. Then, the printed matter which has been cut are conveyed by the conveyance rollers 336 and 337 and discharged to the paper delivery tray 30C.
Here, description will be given for a relation of the number of sheets and pages of printed matter subjected to the saddle stitching process.
In a case where printed matter subjected to a 2-UP and double-sided printing is configured by a plurality of sheets and subjected to the saddle stitching process, when pages of images in printing data have a first page to an nth page as shown in
Then, first, second, n−1th and nth pages are printed on a first sheet with the 2-up and double-sided printing, and third, fourth, n−2th and n−3th pages are printed on a second sheet.
In this manner, n/2−2th, n/2−3th, n/2+3th and n/2+4th pages are printed on an n/4−1th sheet, and n/2th, n/2−1th, n/2+1th and n/2+2th pages are printed on a last n/4th sheet.
Next, description will be given for output processing by top/bottom borderless printing in the saddle stitch printing which is executed by the image forming apparatus 10 in the image output system 1 of the present embodiment.
When top/bottom borderless printing is performed in the saddle stitch printing of the 2-up printing by the image forming apparatus 10 in the image output system 1 of the present embodiment, output processing is performed in a state where a printing area in which an image is printed is formed to be larger than a sheet size in a vertical direction and a gap between two images is eliminated.
Specifically, as shown in
Then, as shown in
Further, by performing output in a state that the printing area in which the images G1 and G2 are printed, is formed larger than the sheet size in the vertical direction, it is possible to realize top/bottom borderless printing with a full of the sheet size in which parts C1 and C2 beyond the sheet size are not output as shown in
Here, description will be given for a reason why the blank spaces B1 and B2 are set in right and left of a sheet.
In an electrophotographic system, it is necessary to perform control so that toner is not adhered to a tip end of a sheet in a sheet conveyance direction. In a case where toner is adhered to the tip end of the sheet, when the sheet after transfer passes through a process component such as a photosensitive member, a transfer belt or a fixing roller, due to adhering force of the toner which is adhered to the tip end of the sheet, the tip end of the sheet is possibly wound around the process component to cause paper jam.
For such a reason, the blank spaces B1 and B2 are set on right and left of the sheet.
Note that, when forming the blank space, at least any one of a tip end side and a rear end side in the sheet conveyance direction may be the blank space.
When the blank space is formed on one side of the sheet, images become non-symmetrical on both sides of a spread page, and therefore, in the case of a specification in which two images have different magnifications, etc., it is necessary to make consideration for a design. When blank spaces are formed on both sides of the sheet, such consideration becomes unnecessary.
Next, description will be given for a case where setting of top/bottom borderless printing is performed by a printer driver in the image output system 1 of the present embodiment.
When the printing setting is performed by the printer driver included in the information processing apparatus 20 in the image output system 1 of the present embodiment, as shown in
In the present embodiment, as one example of the printing setting, the printing setting is performed by setting the saddle stitch printing (2-up) in a double-sided printing item 211, setting “left” to a binding edge and two sites to a staple, and selecting (checking) “top/bottom borderless” in an output item 212 among setting items.
Further, when cutting processing is set as post-processing, “cut” is selected in the output item 212, and a cutting setting screen 220 is displayed as shown in
By performing the setting of the post-processing as described above, when a sheet size of a document is A4, an output sheet size becomes A3, so that the printer driver passes a size that a printing area in a top-bottom direction is larger than A4 to an opened application, and data returned from the application to the printer driver also has a size larger than A4 regarding the top-bottom direction.
Then, for printing data generated by the information processing apparatus 20 as well, a print job like an image shown in
The image forming apparatus 10 receiving the print job generated by the information processing apparatus 20 generates image data by eliminating a blank space of the center part between the two images and treating this eliminated blank space as right and left blank spaces as shown in
Finally, since the size in the top-bottom direction is larger than a size of an A3-sheet as shown in
Next, description will be given for processing for cutting one side as a fore edge side of printed matter subjected to the saddle stitching process in the image forming apparatus 10 with reference to drawings.
In the present embodiment, for printed matter subjected to the saddle stitching process by applying staples at two sites in a center part of the printed matter after the saddle stitch printing, one side as a fore edge side is to be cut.
The post-processing apparatus 30 mounted in the image forming apparatus 10 includes, as shown in
In the image forming apparatus 10, when the printed matter to which a layout by the saddle stitch printing is performed by the print engine 11 is conveyed to the post-processing apparatus 30 shown in
Then, when the printed matter which is folded in half is conveyed to the trimmer unit 370, as shown in
Next, description will be given for processing for generating and transmitting a print job by using the printer driver in the information processing apparatus 20 of the image output system 1 of the present embodiment along a flowchart.
In the image output system 1 of the present embodiment, when a printing setting is performed, as shown in
Then, it is judged whether or not top/bottom borderless printing is set (step S2).
When it is judged that the top/bottom borderless printing is set at step S2, instructions are given to an application to increase a printing area in a top-bottom direction (step S3), and printing data is generated in the command generation portion 243 based on data transmitted from the application (step S4).
On the other hand, when it is judged that the top/bottom borderless printing is not set at step S2, the procedure directly proceeds to step S4.
Then, a print job is passed to a printing port and the print job is transmitted to the image forming apparatus 10 (step S5).
In this manner, the print job is generated by the information processing apparatus 20 and the generated print job is transmitted to the image forming apparatus 10.
Next, description will be given for processing for eliminating a blank space in a center part of printed matter when the saddle stitch printing is performed in the image forming apparatus 10 of the image output system 1 of the present embodiment along a flowchart.
In the image output system 1 of the present embodiment, when image formation is performed by the image forming apparatus 10 based on a print job transmitted from the information processing apparatus 20, as shown in
Then, it is judged whether or not the saddle stitch printing is set (step S12).
When it is judged that the saddle stitch printing is set at step S12, image formation is performed by moving images to be printed to the center part of a sheet to eliminate a blank space between the images (step S13).
On the other hand, when it is judged that the saddle stitch printing is not set at step S12, the step is finished as it is.
In this manner, it is possible to eliminate the blank space in the center part of the printed matter in the saddle stitch printing by the image forming apparatus 10.
Next, description will be given for a process for cutting a fore edge side of printed matter which has been subjected to the saddle stitching process after having performed the top/bottom borderless printing, in the image forming apparatus 10 of the image output system 1 of the present embodiment along a flowchart.
In the image output system 1 of the present embodiment, when the saddle stitch borderless printing is performed, as shown in
Then, the printed matter is folded in half in the folding processing unit 360 (step S22). Data of a print job from the information processing apparatus 20 is then confirmed (step S23), and it is judged whether or not a cutting process for cutting one side as a fore edge side is set (step S24).
When it is judged that the cutting process for cutting one side as the fore edge side is set at step S24, one side as the fore edge side of the printed matter is cut with a cutting width which is set, in the trimmer unit 370 (step S25).
On the other hand, when it is judged that the cutting process for cutting one side as the fore edge side is not set at step S24, the step is finished as it is.
In this manner, by cutting one side as the fore edge side of the printed matter after performing the saddle stitching process by the image forming apparatus 10, it is possible to perform the saddle stitch borderless printing.
According to the present embodiment configured as above, in the image output system 1 configured by including the image forming apparatus 10 provided with the print engine 11 that performs the saddle stitch printing for a sheet, the stapling portion 17 that performs the saddle stitching process for the printed matter, and the cutting portion 19 that cuts an end portion of the printed matter, and the information processing apparatus 20 having a function of instructing an outputting process to the image forming apparatus 10; a function of performing the top/bottom borderless printing is included as a function of the print engine 11, a function of cutting one side as the fore edge side of the printed matter subjected to the saddle stitching process is included as a function of the cutting portion 19, and the image forming apparatus 10 cuts the one side as the fore edge side of the printed matter subjected to the saddle stitching process after the top/bottom borderless printing in response to instructions from the information processing apparatus 20, thus making it possible to perform the borderless printing just by cutting only one side of the printed matter with a simple configuration. This makes it possible to realize a saddle stitched booklet by the borderless printing which allows to shorten a cutting time without making a mechanism for cutting complicated.
Moreover, according to the present embodiment, the top/bottom borderless printing of the saddle stitch printing is performed so that a print job in which printing is performed with a printing area in a top-bottom direction having a size larger than a sheet size, is generated by the information processing apparatus 20 and the printing process is executed based on the print job by the image forming apparatus 10, thus making it possible to eliminate a blank space in the top-bottom direction easily.
Further, according to the present embodiment, the top/bottom borderless printing is performed so that a print job in which printing is performed by eliminating a blank space between two images, which is formed in a center, when the saddle stitch printing is performed with the 2-up printing, is generated by the information processing apparatus 20, and the printing process is executed based on the print job by the image forming apparatus 10, thus making it possible to perform the border less printing without a central blank space easily.
Furthermore, according to the present embodiment, the top/bottom borderless printing is performed so that a print job in which printing is performed with a size in a left-and-right direction larger than a blank space between two images, which is formed at a center, when the saddle stitch printing is performed with the 2-up printing, is generated by the information processing apparatus 20, and the printing process is executed based on the print job by the image forming apparatus 10, thus making it possible to increase a printing area in the left-and-right direction easily.
Moreover, according to the present embodiment, as the configuration of the image forming apparatus 10, when one side as the fore edge side of the printed matter is cut, a function of specifying a width to be cut, that is, the cutting setting screen 220 is displayed to perform detailed setting for cutting, thus making it possible to specify the width to be cut and finely adjust a size of the printed matter easily.
For example, by setting a void width in the sheet conveyance direction to a cutting width of the fore edge side as the cutting width of the printed matter, it is possible to set the cutting width correctly.
Description will be given below with reference to drawings.
Specifically, when a distance between the positioning portion 371 and the trimmer cutter 372 is L1 as shown in
With such a structure, it is possible to set the cutting width of the printed matter correctly, thus making it possible to realize a saddle stitched booklet without a blank space.
Note that, the present embodiment is configured so that top/bottom borderless printing is allowed in the printing portion, but further may be configured so as to restrict the number of sheets for successive printing of borderless pages.
Specifically, when the top/bottom borderless printing is performed as shown in
Though the remaining toner is normally removed by a cleaning function (for example, cleaning unit), when the top/bottom borderless printing is performed, a burden on the cleaning function is increased compared to the normal printing, so that the number of pages for which the top/bottom borderless printing is allowed may be restricted so as not to increase the burden excessively.
For example, the top/bottom borderless printing may be performed only for a front surface of a first sheet (a surface serving as a cover or a back cover) of the print job shown in
With such a configuration, it is possible to suppress a quantity of toner (remaining toner) applied to an outer side of the sheet by the top/bottom borderless printing, thus making it possible to prevent the excessive burden from being put on the cleaning function which removes the remaining toner.
Moreover, the present embodiment is configured so that the saddle stitch borderless printing is easily performed by the image output system 1 configured by including the image forming apparatus 10 and the information processing apparatus 20 having a function of instructing an outputting process to the image forming apparatus 10, but the present invention is not limited to the configuration described above, and may be configured such that, for example, in an image forming apparatus provided with a control portion that performs control so as to perform the cutting process according to the saddle stitch printing and the saddle stitching process, the control portion performs control so that one side as a fore edge side of printed matter subjected to the saddle stitching process after the top/bottom borderless printing, is cut. With such a configuration, it is possible to perform the borderless printing just by cutting only one side of the printed matter with a simple configuration in the same manner as the image output system 1 of the embodiment described above. This makes it possible to realize a saddle stitched booklet by borderless printing which allows to shorten a cutting time without making a mechanism for cutting complicated.
As described above, the present invention should not be limited to the embodiment described above, and various changes can be made within the range specified in the scope of claims. That is, any embodiment obtained by combination of technical means modified as appropriate without departing from the spirit and scope of the present invention should be included in the technical scope of the present invention.
