なお、指定されたスタンプ色を実現するためのフレーム（スタンプデータ格納領域）が、指定されたカラーモードを実現するために必要なフレームに含まれない場合、別途そのスタンプのみを描画するフレームを設定する必要がある。
一方、指定されたスタンプ色を実現するためのフレームが、指定されたカラーモードを実現するために必要なフレームに含まれる場合、指定されたカラーモードで用意されたフレームに対して処理（合成）を行うので、別途そのスタンプのみを描画するフレームを設定する必要はない。

例えば、本文印刷に対するスタンプ印字をレッドに、合紙印刷に対するスタンプ印字をイエローにそれぞれ選択した場合、本文印刷時は原稿の画像データのイエローとマゼンタの各プレーンデータ格納用のメモリ空間にそれぞれスタンプデータを重ね合わせて合成し、合紙印刷時は原稿の画像データのイエローのプレーンデータ格納用のメモリ空間にスタンプデータを重ね合わせて合成する。
すなわち、コントローラ１０が、スタンプ印字機能と合紙印刷モードを有し、スタンプ印字機能と合紙印刷モードとの設定値の組合せに基づいて合紙印刷ページを含めて全ページともスタンプ印字を行う場合、合紙印刷ページのスタンプ印字色と本文印刷ページのスタンプ印字色を変更する手段の機能を果たす。

図１２は、合紙印刷モード時に本文印刷と合紙印刷に対してそれぞれ独立にスタンプ色を指定して印字する処理のフローチャート図である。
コントローラ１０は、ステップ（図中「Ｓ」で示す）１で画像メモリを必要なプレーン（プレーンデータ格納用のメモリ空間）数だけ確保し、ステップ２で確保した各画像メモリをクリア（初期化）し、ステップ３で原稿の画像の読み取りを実行し、本文印刷＝未終了を設定し、ステップ４で本文印刷＝終了か否かを判断し、本文印刷＝終了でなければ、ステップ８へ進んで原稿から読み取った画像データの各プレーンデータ格納用のメモリ空間に対して予め指定された本文印刷用のスタンプ印字色に必要なプレーンデータ格納用のメモリ空間にスタンプ印字データを合成し、ステップ９で本文印刷用の記録紙がセットされた本文給紙段から記録紙を給紙し、その記録紙に本文とスタンプからなる画像を作像して印刷し、上記設定を本文印刷＝終了に変更してステップ４へ戻る。
【００４１】
ステップ４の判断で今度は本文印刷＝終了なので、ステップ５へ進んで原稿から読み取った画像データの各プレーンデータ格納用のメモリ空間に対して予め指定された合紙印刷用のスタンプ印字色に必要なプレーンデータ格納用のメモリ空間にスタンプ印字データを合成し、ステップ６で合紙印刷用の記録紙がセットされた合紙給紙段から記録紙を給紙し、その記録紙に本文とスタンプからなる画像を作像して印刷し、ステップ７で全ページの原稿の読み取りが終了したか否かを判断し、終了しなければステップ２へ戻って上述の処理を繰り返し、このようにして、スタンプ付き本文とスタンプ付き合紙の印刷を交互に繰り返して全てのページの読み取りが終了したら、この処理を終了する。
【００４２】
図１３は、合紙印刷モード時に本文印刷と合紙印刷に対してそれぞれ独立にスタンプ色を指定して印字した結果の一例を示す図である。
例えば、本文の各ページの右下あたりにレッド（赤色）で秘密書類であることを示す丸秘のスタンプを印字し、合紙の各ページの右下あたりにブラック（黒色）で秘密書類であることを示す丸秘のスタンプを印字した場合を示している。
このようにして、スタンプ印字機能と合紙印刷モードの設定値の組合せにより、合紙印刷のスタンプと本文印刷のスタンプの印字色を変更することが可能なので、ユーザが所望する印刷結果が得られる効果がある。

Next, a basic configuration of a digital color copying machine which is an embodiment of the image forming system of the present invention will be described.
FIG. 1 is a block diagram showing a schematic configuration mainly of an engine unit of a digital color copying machine which is an embodiment of an image forming system of the present invention.
[Description of image forming operation]
As shown in FIG. 1, this digital color copying machine has a sheet-through type automatic document feeder (hereinafter referred to as “ADF”) 1 and simultaneously has a small size (in this embodiment, 216 mm or less) on an intermediate transfer belt 51. ), Image transfer for two surfaces can be performed, and in the case of a large size (over 217 mm), image transfer for only one surface can be performed. In addition to the ADF 1, the document reader 2, the image writing unit 3, the image forming unit 4, the primary transfer unit 5, the secondary transfer unit 6, and the fixing unit 7 are included.
[0014]
The ADF 1 reads a document to be scanned by sending the document to be scanned into the document reader 2 at a speed suitable for the copy magnification desired by the user.
The document reading apparatus 2 includes a carriage 21 having a light source, a plurality of mirrors, a lens 22, a CCD 23, and a buffer 24, and scans a document sent by the ADF 1 to perform a full color mode, a monochrome mode, a single color mode, and a two-color mode. Then, the image of the original is read, and the read image data (image information) for each color of yellow, magenta, cyan and black is transferred to the memory of the controller which will be described later.
The image writing unit 3 includes a laser light source and a polygon mirror, and sends a laser beam 31 including image data to the image forming unit 4.
[0015]
The image forming unit 4 includes a charging charger 42 arranged around the photoconductor 41, an irradiation portion of the laser beam 31 from the image writing unit 3, black (K), cyan (C), magenta (M), yellow (Y ) Or a drum cleaning unit 44, and an electrostatic latent image is formed on the photosensitive member 41 by the laser beam 31, and the formed electrostatic latent image is converted into a color developing unit. The toner image is formed by being visible at 43.
The primary transfer unit 5 includes an intermediate transfer belt 51, a primary transfer unit 52, a tension roller 53, two secondary transfer rollers 54 and 55, and a cleaning unit 56, and a toner image formed on the photoconductor 41. Primary transfer is performed on the intermediate transfer belt 51.
[0016]
The intermediate transfer belt 51 can transfer two toner images simultaneously. The intermediate transfer belt 51 is separated from the surface of the photosensitive member 41 by a contact / separation mechanism (not shown) except when the toner image on the photosensitive member 41 is primarily transferred, and only when the intermediate transfer belt 51 is primarily transferred to the intermediate transfer belt 51. 41 is pressed against the surface.
The secondary transfer unit 6 secondarily transfers the toner image transferred to the intermediate transfer belt 51 onto a transfer material. In this digital color copying machine, the order of image forming colors during full color copying is in the order of yellow (Y) → magenta (M) → cyan (C) → black (K).
[0017]
FIG. 2 is an explanatory diagram showing the concept of colors for forming other colors using yellow (Y), magenta (M), cyan (C), and black (K).
For example, green is visualized by superposing yellow (Y) and cyan (C), red is superposed by yellow (Y) and magenta (M), and blue is visualized by superimposing magenta (M) and cyan (C). Is done.
[0018]
FIG. 3 is a block diagram showing a schematic configuration of mainly a control unit of an image writing unit of a digital color copying machine which is an embodiment of the image forming system of the present invention.
FIG. 4 is an explanatory diagram of processing for transferring image data from the document reading device 2 to the memory 12.

[0019]
The operation unit 8 is an input device through which an operator inputs mode settings such as a full color mode, a monochrome mode, a single color mode, and a two-color mode and various operation information. The IPU 16 is an image processing apparatus and performs various filter processes. Although not shown, there is also a color determination device that determines whether or not a read original is a color original.
The controller 10 stores image data that has been subjected to various processes by the IPU 16 connected via the motherboard 15 and transfers the image data to the printer engine 9 (image memory, system memory) 12 and various types of data. The program ROM 11 stores a control program for controlling the above, a hard disk drive (HDD) 13 that is optionally added, and a real time clock (RTC) 14 that measures the date and time. It also functions as a transfer device that transfers the image data for each color stored in the memory 12 to the printer engine for each color.
[0020]
The document reading device 2, the IPU 16, the controller 10, and the printer engine 9 are connected by an image bus capable of command communication.
The Y, M, C, and K component image data from the document reader 2 are simultaneously read and transferred to the memory 12 of the controller 10 via the video bus. 1 line data of Y, M, C, and K is stored in the memory space for storing each plane data in the memory 12 of the controller 10.
[0021]
As shown in FIG. 4, the Y component (1-line data of Y) is written into the yellow (Y) storage area (memory space for storing plane data for yellow) in the memory 12 of the controller 10 and stored in magenta (M). The M component (M 1-line data) is written in the area (memory space for storing plane data for magenta), and the C component (the memory space for storing plane data for cyan) is written in the cyan (C) storage area (memory space for storing plane data for cyan). 1 line data) is written, and the K component (1 line data of K) is written in the black (K) storage area (memory space for storing plane data for black).
That is, the memory 12 is an image storage device that stores an image read by the document reading device 2 as image data for each color of yellow, magenta, cyan, and black.
[0022]
In the following description, the resolution of the copy read image is 1 pixel = 600 dpi / binary data, but the quantization is not particularly limited.
For example, when 1 pixel = 600 dpi / 8-bit gradation, it is simply 8 times.
In the case of the above premise, the amount of image memory required for each color (Y, M, C, K) of A3 size (420 mm × 297 mm) is {420 (mm) × 600 (dpi) /25.4 (mm)} x {297 (mm) x600 (dpi) /25.4 (mm)} = 699605059 (dot), and 1 byte = 8 dots (bit) as image data, so 69605059/8 = 87000632 (bytes) = 8 .7 (Mbyte) (this is an image memory per plane).
[0023]
Next, a description will be given of color mode processing performed in the digital color copying machine.
FIG. 5 is an explanatory diagram of a single color copy process performed in this digital color copying machine.
FIG. 6 is an explanatory diagram of a two-color copy process carried out by this digital color copying machine.
[0024]
{Single color copy}
As shown in FIG. 5, this is a mode in which a document is copied with a designated one color.
Even for the same single color, yellow, magenta, cyan, and black are copied with one color toner, for example, red, green, and blue are copied using two color toners. The color conversion is performed when the original is read by the IPU 16 shown in FIG.
Therefore, the controller 10 uses one space (one plane) of memory space for storing plane data as the image memory of the memory 12 when copying in any one color of Y, M, C, and K by single color copy. However, when copying with other colors, two memory spaces for storing plane data (two planes) are used.
[0025]
{2 color copy}
As shown in FIG. 6, this is a mode in which the original is copied in two colors designated as black. As shown in the colors (1) and (2) in the figure, the “other than black portion” of the original is changed to (1). It is possible to change to the color of ▼ and to change the “black part” of the document to the color of (2).
Even if the same two colors are used, if two-color copy is specified for output colors of only yellow, magenta, cyan, and black, copying is performed with two colors of toner, but depending on the combination, two toners of Y, M, C, and K may be used. Color, 3-color or 4-color toner is used.
[0026]
For example, red, green, and blue are copied using two color toners. Therefore, the controller 10 uses two planes of memory space for storing plane data as the image memory of the memory 12 when copying in any two colors of Y, M, C, and K. When copying by color, 3 planes or 4 planes are used. The color conversion is performed when the original is read by the IPU 16 shown in FIG.
[0027]
{Full color copy}
Although not particularly shown, this is a copy mode for outputting a full-color original in full color. In this case, since the full color output is basically performed with four image forming colors, the controller 10 uses four planes of memory space for storing plane data as the image memory of the memory 12.
[0028]
Next, the stamp printing function of this digital color copying machine will be described.
The stamp printing function is a mode in which image data (stamp image) of a specific stamp is combined with image data of an image read from a document and printed.
Types of stamps include “circulation”, “copying prohibition”, “urgent”, “confidential” and the like. Since each stamp is composed of bitmap data, the type of bitmap data stored may be changed according to the needs of the user and the digital color copying machine.
[0029]
FIG. 7 is an explanatory diagram of stamp printing control processing.
When printing for stamping “copy prohibited” in the stamp printing mode is started, the controller reads out “copy prohibited” image data (bitmap data) stored in advance in the optional HDD 13 or ROM (not shown). 10 is read out on the memory 12 and (2) the reading of the document image by the document reading device 2 is started. (3) Waiting for the completion of the reading of the document image and the transfer of the image data, (4) the image of the document. The data is subjected to a composition process for superimposing image data of “no copy” on the data, and (5) after the composition process, a process of outputting video (image) to the printer engine is sequentially performed to perform stamp printing on the print page.
[0030]
Next, the page printing function of this digital color copying machine will be described.
The page printing function is a mode in which the image of the page number is combined with the image data of the image read from the document and printed.
FIG. 8 is an explanatory diagram of page printing.
For example, for each image of five originals, p. 1-p. 5 page numbers are output in succession. The page number printing types include “−1−”, “−p.1”, and “1/10”.
Since the image data for page printing is composed of bitmap data, the type of bitmap data to be stored may be changed in accordance with the needs of the user and the digital color copying machine for the font image to be printed.
[0031]
FIG. 9 is an explanatory diagram of a page printing control process.
When page printing is started in the “-p.1-” format in the page print mode, (1) page print data (in the “-p.1-” format stored in advance in the option HDD 13 or ROM not shown). Image data) is read out and developed on the memory 12 of the controller 10, and (2) the document reading device 2 starts reading the document image, and (3) waits for the completion of the document image reading and image data transfer. , (4) The image data of the original is overlaid with the page image data (bitmap data), and (5) The video (image) is sequentially output to the printer engine after the composition processing, and printing is performed. Print the page on the page.
[0032]
Next, the date printing function of this digital color copying machine will be described.
The date printing function is a mode for printing by adding the current date (when copying is started) to the read image data of the document.
Examples of date types include “YYYY.MM.DD”, “YY.MM.DD”, “YYMM / DD” (YY, YYYY represents year, MM represents month, and DD represents day).
[0033]
FIG. 10 is an explanatory diagram of the date printing control process.
(1) This date data can be acquired from the RTC 14 in the controller 10 shown in FIG. 3, and the date data is developed as bitmap data on the memory 12 of the controller 10 and (2) by the document reader 2. Start reading the original image, wait for the completion of (3) reading of the original image and transfer of the image data, and (4) compositing the image data (bitmap data) of the date data on the original image data. (5) After the synthesizing process, the process of outputting video (image) to the printer engine is sequentially performed, and the date is printed on the print page.
[0034]
Next, the slip sheet printing mode of this digital color copying machine will be described.
FIG. 11 is an explanatory diagram of the slip sheet printing mode.
The slip sheet printing mode is a mode for copying the same image onto a slip sheet for a copy of a document. In particular, when copying on an OHP, there is a case in which a slip sheet is inserted into each print result (text) of an original (hereinafter, the first copy to be printed is a text print, a slip sheet feed stage). The copy fed from the printer is called interleaf printing).
As operations, two types are selected: a paper feed stage for setting the recording paper for printing the text and feeding the paper at the time of printing, and an interleaf paper stage for setting the slip sheet and feeding at the time of printing. In particular, colored paper or the like different from the main text is often used for the interleaving stage to improve operability.
[0035]
Next, a description will be given of a function for performing stamp printing by designating a stamp color independently for text printing and slip sheet printing in the slip sheet printing mode according to claim 1 of the present invention in the digital color copying machine.
When the slip sheet printing mode is selected by the operation unit 8, the controller 10 performs a process of stamp printing with a stamp color designated independently for the text printing and the slip sheet printing.
[0036]
The stamp color of each stamp print is Y (yellow), M (magenta), C (cyan), K (black), R (red), G (green), B (shown in Table 1 below) by the operation unit 8. Any one color can be selected from the seven colors (blue).
In accordance with the selected color, the stamp data is combined with the image data stored in the memory space for storing each plane data of the image memory in the memory 12 (that is, using FIG. 7 described above). Print data is added according to the stamp printing control explained above).
[0037]
[Table 1]

[0038]
If the frame (stamp data storage area) for realizing the specified stamp color is not included in the frame necessary for realizing the specified color mode, a frame for drawing only that stamp is set separately. There is a need to.
On the other hand, when a frame for realizing the specified stamp color is included in a frame necessary for realizing the specified color mode, processing (compositing) is performed on the frame prepared in the specified color mode. Therefore, there is no need to set a frame for drawing only the stamp.
[0039]
For example, if stamp printing for text printing is selected as red and stamp printing for slip sheet printing is selected as yellow, the stamp data is stored in the memory space for storing the original image data yellow and magenta plane data at the time of text printing. Are combined and stamp data is superimposed and combined with the memory space for storing the yellow plane data of the image data of the original during interleaf printing.
That is, the controller 10 has a stamp printing function and a slip sheet printing mode, and performs stamp printing on all pages including a slip sheet printing page based on a combination of setting values of the stamp printing function and the slip sheet printing mode. The function of means for changing the stamp print color of the interleaf print page and the stamp print color of the body print page is achieved.
[0040]
FIG. 12 is a flowchart of processing for printing by specifying a stamp color independently for the text printing and the slip printing in the slip sheet printing mode.
The controller 10 secures the image memory in the number of necessary planes (memory space for storing plane data) in step (indicated by “S” in FIG. 1), and clears (initializes) each image memory secured in step 2. In step 3, the image of the original is read, and “text printing = not finished” is set. In step 4, it is determined whether or not the text printing = end. If the text printing = not finished, the process proceeds to step 8. In step 9, the stamp print data is synthesized in the plane data storage memory space required for the text print stamp print color specified in advance for each plane data storage memory space of the image data read from the document. Feed the recording paper from the body feeding stage where the recording paper for body printing is set, create an image consisting of the body and stamp on the recording paper, print it, and print the above settings to the body. Change in the end return to step 4.
[0041]
Since the text printing is finished at this time in step 4, the process proceeds to step 5 and is necessary for the stamp printing color for slip sheet printing specified in advance for the memory space for storing each plane data of the image data read from the original. The stamp print data is synthesized in a memory space for storing plain data, and in step 6, the recording paper is fed from the interleaf paper feed stage in which the recording paper for interleaf printing is set, and the text and the stamp are printed on the recording paper. An image composed of the following is formed and printed. In step 7, it is determined whether or not reading of all pages of the document has been completed. If not, the process returns to step 2 to repeat the above-described processing. When all the pages have been read by alternately repeating the printing of the stamped text and the stamped slip, this process is terminated.
[0042]
FIG. 13 is a diagram illustrating an example of a result of printing by specifying a stamp color independently for the text printing and the slip printing in the slip sheet printing mode.
For example, a secret stamp indicating that it is a confidential document is printed in red (red) around the lower right of each page of the body, and a black (black) secret document is printed around the lower right of each page of the slip. This shows a case where a secret stamp is printed.
In this way, the print color desired by the user can be obtained because the print color of the interleaf printing stamp and the body printing stamp can be changed by a combination of the stamp printing function and the setting value of the interleaf printing mode. effective.
[0043]
Next, a description will be given of a function for performing page printing by designating page number colors independently for the text printing and the slip sheet printing in the slip sheet printing mode according to claim 2 of the present invention in the digital color copying machine.
When the slip sheet printing mode is selected by the operation unit 8, the controller 10 performs a process of printing the page number with the page number color designated independently for the text printing and the slip sheet printing.
[0044]
Each page number printing color is selected by the operation unit 8 as shown in Table 2 below: Y (yellow), M (magenta), C (cyan), K (black), R (red), G (green), B (blue) 1) any one of the seven colors can be selected.
In accordance with the selected color, page print data is synthesized with the image data stored in the memory space for storing each plane data of the image memory in the memory 12 (that is, using FIG. 8 described above). The print data is added according to the page printing control described above).
[0045]
[Table 2]

[0046]
If the frame (page print data storage area) for realizing the specified page print color is not included in the frame necessary for realizing the specified color mode, only that page print is drawn separately. It is necessary to set the frame to be used.
On the other hand, when the frame for realizing the specified page printing color is included in the frame necessary for realizing the specified color mode, processing is performed on the frame prepared in the specified color mode ( Therefore, it is not necessary to separately set a frame for drawing only the page printing.
[0047]
For example, if page printing for text printing is selected in red and page printing for slip-sheet printing is selected in yellow, page printing is performed in the memory space for storing the original image data yellow and magenta plain data. The data is superimposed and combined, and at the time of interleaf printing, the page print data is superimposed and combined in the memory space for storing the yellow plane data of the image data of the original.

Acts as a means to change color.
[0048]
FIG. 14 is a flowchart of a process for printing by specifying the page number color independently for the body text printing and the slip sheet printing in the slip sheet printing mode.
The controller 10 secures as many image memories as the number of necessary planes (memory space for storing plane data) in step (indicated by “S” in the figure) 11 and clears (initializes) each image memory secured in step 12. In step 13, the image of the original is read, and the text printing = not finished is set. In step 14, it is determined whether the text printing = end. If the text printing = not finished, the process proceeds to step 18. The page print data is synthesized in the memory space for storing plane data necessary for the page print color for text printing specified in advance for each memory space for storing plain data of image data read from the document. Feed the recording paper from the body feeding stage with the recording paper for body printing, create an image consisting of the body and page number on that recording paper, print it, Change the text printing = Exit returns to step 14.
[0049]
Since the printing of the text is finished at this time in the determination of step 14, the process proceeds to step 15 and is necessary for the page printing color for slip sheet printing specified in advance for the memory space for storing each plane data of the image data read from the original. Page print data is combined into a memory space for storing plain data, and the recording paper is fed from the interleaf paper feed stage in which the recording paper for interleaf printing is set in step 16, and the body and page are recorded on the recording paper. An image consisting of a number is created and printed, and it is determined in step 17 whether or not reading of all pages of the document has been completed. If not, the process returns to step 12 and the above processing is repeated. When the reading of all pages is completed by alternately repeating the printing of the body with page numbers and the interleaved paper with page numbers, this processing is terminated.
[0050]
FIG. 15 is a diagram illustrating an example of a result of page printing by designating page colors independently for the body text printing and the slip sheet printing in the slip sheet printing mode.
For example, each page number (-P1-, -P2-, -P3-,...) Is printed in red (red) in the lower right margin of each page of the text, and the lower right corner of each page of the slip sheet. The page numbers (-P1-, -P2-, -P3-,...) Are printed in black (black) in the margin.
In this way, the page print color for interleaf printing and the page print color for body printing can be changed by combining the set values of the page print function and interleaf print mode, so that the user can obtain the desired print result. There is an effect.
[0051]
Next, a description will be given of a function for performing date printing by designating a date printing color independently for text printing and slip printing in the slip sheet printing mode according to claim 3 of the present invention in the digital color copying machine.
When the slip sheet printing mode is selected by the operation unit 8, the controller 10 performs a process of printing the date with the date print color designated independently for the text printing and the slip sheet printing.
[0052]
Each date print color is Y (yellow), M (magenta), C (cyan), K (black), R (red), G (green), B (blue) shown in Table 3 below by the operation unit 8. Any one of the seven colors can be selected.
In accordance with the selected color, the date print data is synthesized with the image data stored in the memory space for storing each plane data of the image memory in the memory 12 (that is, using FIG. 10 described above). The print data is added according to the date printing control explained above).
[0053]
[Table 3]

[0054]
If the frame for realizing the specified date printing color is not included in the frame necessary for realizing the specified color mode, it is necessary to set a frame for drawing only that date printing. is there.
On the other hand, when the frame for realizing the specified date printing color is included in the frame necessary for realizing the specified color mode, processing is performed on the frame prepared in the specified color mode ( Therefore, there is no need to separately set a frame for drawing only the date printing.
[0055]
For example, if date printing for text printing is selected as red and date printing for slip sheet printing is selected as yellow, date printing is performed in the memory space for storing the original image data yellow and magenta plain data respectively. The data is superimposed and combined, and at the time of interleaf printing, the date print data is superimposed and combined in the memory space for storing the yellow plane data of the image data of the original.
That is, the controller 10 has a date printing function and a slip sheet printing mode, and based on a combination of setting values of the date printing function and the slip sheet printing mode, the date print color of the slip sheet print page and the date print of the body print page Acts as a means to change color.
[0056]
FIG. 16 is a flowchart of a process for performing printing by designating the date print color independently for the body text printing and the slip sheet printing in the slip sheet printing mode.
The controller 10 secures the image memory by the number of necessary planes (memory space for storing plane data) in step (indicated by “S” in the figure) 21 and clears (initializes) each image memory secured in step 22. In step 23, the image of the original is read, and the text printing = not finished is set. In step 24, it is determined whether the text printing = end. If the text printing = not finished, the process proceeds to step 28. In step 29, the date print data is synthesized in the memory space for storing plain data necessary for the date print color for text printing specified in advance for the memory space for storing plain data of image data read from the document. Feed the recording paper from the body feeding stage where the recording paper for body printing is set, create an image consisting of the body and date on the recording paper, print it, and print the above settings to the body. Change in the end returns to step 24.
[0057]
Since the text printing is finished at this time in step 24, the process proceeds to step 25 and is necessary for the date printing color for slip sheet printing previously designated for the memory space for storing each plane data of the image data read from the original. The date print data is synthesized into a memory space for storing plain data, and the recording paper is fed from the interleaf paper feed stage in which the recording paper for interleaf printing is set in step 26, and the text and date are recorded on the recording paper. An image consisting of the above is formed and printed, and it is determined in step 27 whether or not reading of all pages of the document has been completed. If not, the process returns to step 22 and the above processing is repeated. When the printing of the text with date and the slip sheet with date is alternately repeated and all the pages have been read, this process ends.
[0058]
FIG. 17 is a diagram illustrating an example of a result of date printing by designating a date printing color independently for the main body printing and the slip sheet printing in the slip sheet printing mode.
For example, the date (2002.1.1) is printed in red (red) in the lower right margin of each page of the body, and the date (2002. 1) is printed in black (black) in the lower right margin of each page of the slip sheet. .1) is printed.
In this way, the date printing color for the slip sheet printing and the date printing color for the body printing can be changed by combining the setting values of the date printing function and the slip sheet printing mode, so that the print result desired by the user can be obtained.
