In addition, the control portion 10 may read the stamp setting 310 that has already been set, from an external recording medium (not shown).
(Step S101)
Next, the control portion 10 performs a print data obtaining process by using the print data obtaining portion 100. The control portion 10 causes the document sheet reading portion 12 to read the document sheet set in the document sheet conveying portion 13, obtains the image data thereof as the print data 300, and stores the print data 300 in the storage portion 19.
In addition, the control portion 10 may obtain, as the print data 300, image data of a document sheet or the like received by facsimile from the FAX transmission and reception portion 18, and store the print data 300 in the storage portion 19. Furthermore, the control portion 10 may cause the network transmission and reception portion 15 to receive the print data 300, which has been output by a device driver from one of various types of application software of an external terminal, via an external network, and store the print data 300 in the storage portion 19. Furthermore, the control portion 10 may obtain the print data 300 from a connected recording medium (not shown), and store the print data 300 in the storage portion 19.
It is noted that the control portion 10 may obtain a user ID and a password by allowing the user to input them via the input portion of the operation panel portion 16 or a terminal, and perform a user authentication. Furthermore, the control portion 10 may perform a user authentication by using an IC card or the like.
(Step S102)
Subsequently, the control portion 10 performs a per page pane information calculating process by using the pane information calculating portion 110. The control portion 10 calculates the recording sheet number 322 of a recording sheet, on which an image is to be formed, and the drawing position 323, for each piece of page data 302 included in the obtained print data 300, and stores the recording sheet number 322 and the drawing position 323 as the pane information 320 in the storage portion 19.
The control portion 10 refers to, for example, the printing method specified in the attribute information 301 of the print data 300, and calculates on which of a front surface or a rear surface of what number of recording sheet, the panes of each piece of page data 302 are disposed. In addition, the control portion 10 calculates the size and position of each pane by referring to the information of the position and size of margins and mark lines included in the printing method.
For example, in the example of the booklet printing shown in
(Step S103)
Next, the control portion 10 determines whether or not the pane information calculating portion 110 has completed the calculation of the pane information 320. When the calculation of the pane information 320 for all pieces of page data 302 included in the print data 300 has been completed, the control portion 10 determines as Yes. Otherwise, the control portion 10 determines as No. When determined as Yes, the control portion 10 causes the process to proceed to step S104. When determined as No, the control portion 10 returns the process to step S102 and continues the calculation of the pane information 320.
(Step S104)
When it is determined that the calculation of the pane information 320 for all pages has been completed, the control portion 10 performs a per page stamp information calculating process by using the stamp drawing information calculating portion 120. The control portion 10 reads out the stamp setting 310 and retrieves on what page of the print data 300 the stamp is to be drawn. The control portion 10 makes the recording sheet number 322 and the drawing position 323 of the pane information 320 of the retrieved page data 302 correspond to the recording sheet number 332 and the drawing position 333 of the stamp drawing information 330. Furthermore, the control portion 10 makes the recording sheet number 322 of the pane information 320, which corresponds to a target page, correspond to the recording sheet number 332 of the stamp, and calculates the drawing position 333 from the drawing position 323.
The following describes an example where the stamp setting 310 has been made for a stamp U3 to be drawn in the bottom center of the recording sheet, and the booklet printing has been set, with reference to
As shown in
(Step S105)
Subsequently, the control portion 10 performs a drawing position changing process by using the stamp drawing information calculating portion 120.
Upon referring to the change setting in the stamp setting 310 or the like and finding that the drawing position needs to be changed due to the double-page spread setting or the like, the control portion 10 changes the drawing position 333 of the stamp drawing information 330. In doing this, the control portion 10 refers to the attribute information 301 of the print data 300, and moves the drawing position 333 of the stamp drawing information 330 rightward or leftward depending on, for example, which of the left or right page of the double-page spread the drawing position of the pane information 320 that corresponds to the recording sheet number 332 of the stamp drawing information 330 is set to.
As shown in
Furthermore, in the case where a margin M, which is, for example, a binding margin, has been set in the attribute information 301 of the print data 300, the drawing position of stamp U3 is changed from the center of a recording sheet to two positions horizontally separated from each other with the center in between.
(Step S106)
Next, the control portion 10 determines whether or not the stamp drawing information calculating portion 120 has completed the calculation of the stamp drawing information 330. When the calculation of the stamp drawing information 330 for all pages of the print data 300 set in the stamp setting 310 has been completed, the control portion 10 determines as Yes. Otherwise, the control portion 10 determines as No. When determined as Yes, the control portion 10 causes the process to proceed to step S107. When determined as No, the control portion 10 returns the process to step S104 and continues the calculation of the stamp drawing information 330.
(Step S107)
When it is determined that the calculation of the stamp drawing information 330 has been completed, the control portion 10 performs a page data drawing process by using the stamp drawing portion 130.
The control portion 10 draws the PDL, image data or the like of each piece of page data 302 at a location in the drawing data 340 that corresponds to the recording sheet number 322 and the drawing position 323 of the pane information 320 that correspond to the target piece of page data 302. In doing this, the control portion 10 performs a drawing based on the attribute information 301 of the print data 300. In addition, the control portion 10 may perform enlargement or reduction in the drawing based on the data of the rectangle of the drawing position 323.
(Step S108)
Subsequently, the control portion 10 performs a stamp drawing process by using the stamp drawing portion 130. When there is stamp drawing information 330 that corresponds to the pane information 320 of each piece of page data 302, the control portion 10 draws a stamp at a location in the drawing data 340 that corresponds to the drawing position 333 of the recording sheet number 332.
(Step S109)
Next, the control portion 10 performs a recording sheet number-order output process by using the stamp drawing portion 130. Upon completion of the drawing of the drawing data 340, the control portion 10 causes the image forming portion 17 to form images of the drawing data 340 onto recording sheets in order of the recording sheet number. In the case of the double-side printing, the control portion 10 causes images to be formed on both of the front and rear surfaces of each recording sheet.
In addition, the control portion 10 may cause the FAX transmission and reception portion 18 to transmit the drawing data 340 by facsimile. Furthermore, the control portion 10 may convert the drawing data 340 to the PDF format and output it to a document box in the storage portion 19, or to an external terminal or recording medium.
(Step S110)
Next, the control portion 10 determines, by using the stamp drawing portion 130, whether or not the output of recording sheets for all pages has been completed. When the output of recording sheets for all pages of the print data 300 has been completed, with images or the like having been formed on the recording sheets, the control portion 10 determines as Yes. Otherwise, the control portion 10 determines as No. When determined as Yes, the control portion 10 ends the stamp drawing process. When determined as No, the control portion 10 returns the process to step S107 and continues the drawing of the page data 302 and the stamp and the output of recording sheets.
This completes the stamp drawing process in the embodiment of the present disclosure.
With the above-described structure, the following effects can be produced. According to the above-described typical stamp function, drawing a stamp spanning pages in the booklet printing or the like is not possible. On the other hand, the image forming apparatus 1 in the embodiment of the present disclosure includes the pane information calculating portion 110, stamp drawing information calculating portion 120 and stamp drawing portion 130. With this structure, the stamp drawing information 330 is calculated to indicate, for each pane, whether a stamp is drawn, and thus it is possible to realize a process of drawing a stamp spanning different recording sheets even in the booklet printing or the like. This facilitates, for example, specifying matching faces in the booklet, and improves usability of the user.
In addition, in the image forming apparatus 1 of the embodiment of the present disclosure, the stamp drawing information calculating portion 120 can change the drawing position of the stamp in correspondence with the drawing position of the pane information 320. This makes it possible to draw a stamp of a page number, name or the like in the left and right ends of a double-page spread in the booklet printing or the like. This improves usability in the booklet printing or the like.
It is noted that although, in the embodiment of the present disclosure, realization of a stamp spanning pages in the booklet printing is explained as one example, the present disclosure is similarly applicable to the poster printing, bookbinding printing, and the like. In addition, with regard to the collective printing, the present disclosure is applicable to printing methods for collecting three or more pages, such as “3-in-1”, “4-in-1”, “6-in-1”, “8-in-1” and the like, as well. This ensures that stamps are drawn at all locations where the stamps are required. For example, in the case of the poster printing, it is possible to specify locations at which different recording sheets are to be joined together, by drawing the stamps there. This makes it possible to create a large poster easily by joining a plurality of recording sheets together.
It is to be understood that the embodiments herein are illustrative and not restrictive, since the scope of the disclosure is defined by the appended claims rather than by the description preceding them, and all changes that fall within metes and bounds of the claims, or equivalence of such metes and bounds thereof are therefore intended to be embraced by the claims.
