(First embodiment)
Next, a first embodiment of the present invention will be described.
FIG. 1 is a block diagram showing a basic configuration according to the first embodiment.
In FIG. 1, reference numeral 1 denotes a CPU (central processing unit) that performs control and arithmetic processing of each unit described below. Reference numeral 2 denotes a RAM (Random Access Memory). The RAM 2 functions as a work area in which a program and data are loaded for each process executed by the CPU 1 and data being processed are stored. Reference numeral 3 denotes a ROM (read only memory) which stores a control program for controlling the entire system, a control program for executing a control operation described later, and the like, as well as various data such as font data. Reference numeral 4 denotes a keyboard control unit (KCB) which receives data according to key input from the keyboard 5 (KB) and transmits the data to the CPU 1. Reference numeral 6 denotes a printer control unit (PRTC) for controlling the printer device 7 (PRT). The printer device 7 is a color printer device 7 capable of recording a color image, and includes a laser beam printer, an ink jet printer, or the like. Reference numeral 8 denotes a display control unit (CRTC), which performs display control on the display device 9 (CRT). A disk control unit (DKC) 10 controls data transmission and the like. Reference numeral 11 denotes an external storage device such as a floppy disk device (FD), a hard disk device (HD), or a CD-ROM. The external recording device can store programs and data, and is necessary. Accordingly, data can be referred to or loaded into the RAM 2. A system bus 12 functions as a data transfer path between the above-described components.

  In this embodiment having the above-described configuration, the CPU 1 operates by executing a basic I / O (input / output) program, an OS (operating system), and a misregistration correction program described below.

  The basic I / O program is stored in the ROM 3, and the OS is written in the HD 11a. When the power of the apparatus is turned on, after the OS is read from the HD 11a into the RAM 2 by the IPL (Initial Program Loading) function in the basic I / O program, the operation according to the OS is started.

  In the present embodiment, as shown in FIG. 2, related data such as a misregistration correction control program, directory information, and volume information is stored in the FD 11b or CD-ROM 11c, and stored in the FD 11b or CD-ROM 11c. The document processing program and related data can be installed in the HD 11a of the information processing apparatus (computer) PC constituting the document processing apparatus through the FD drive 10b or the CD-ROM drive 10c as shown in FIG.

  In this case, when the FD 11b or the CD-ROM 11c is set in the FD drive 10b or the CD-ROM drive 10c, the misregistration correction control program and related data are read from the FD 11b or the CD-ROM 11c under the control of the OS and the basic I / O program. And installed in the HD 11a to be operable. FIG. 4 shows a memory map in a state where the document processing program is installed in the HD 11 and becomes executable.

  FIG. 5 is a flowchart in which the client executes the document processing program according to the first embodiment of this invention on the Web server.

  In step S501, the user inputs (transmits) a document to be preflight checked to the Web server side as a client, and the Web server side reads (receives) the document. In step S502, the input document is interpreted and analyzed. In step S503, it is determined whether the analyzed document includes two or more different color spaces. When two or more different color spaces are included, the process proceeds to step S504, one color space that has not been processed yet is selected, and the process proceeds to step S505. If the document does not include two or more different color spaces, that is, if the document includes only one color space, the process proceeds to step S505, where one color space is processed. In step S505, the color space to be processed is identified from among a plurality of types of color spaces.

  In step S506, all objects in the document to which the color space specified in step S505 is applied are selected. In step S507, all selected objects are filled with the same unique color different from other color spaces. In step S508, it is determined whether the processing has been completed for all color spaces included in the document. If it is determined that there is a color space that has not been processed yet, the process returns to step S503, and the same process is performed again in another color space. If it is determined in step S508 that the processing has been completed for all color spaces in the document, the process advances to step S509 to perform rendering. The rendering result is displayed as a preview in step S510, and a preflight check is performed in step S511, whereby the color space of each object can be confirmed.

  FIG. 7 shows an output example in this series of processing. When a document as shown in FIG. 7A is input, a result displayed by the above-described preflight check is as shown in FIG. 7B, for example. In this case, the input document includes three color spaces of DeviceGray, CIEBasedABC, and DeviceRGB, and the objects included in each color space are different.

  In the first embodiment, as shown in FIG. 7B, a document is displayed by painting with a single color for each color space. Thus, it is possible to easily determine which object in the document is described in which color space by looking at the preview before actually printing. As described above, instead of painting with a single color, a method such as using the same shading pattern may be used, and a display that allows the operator to identify which object group is an image in the same color space. Any display method may be used.

  Further, after performing the preflight check, the process proceeds to step S514 to determine whether or not to change the current color space applied to each object to another color space (step S512). In step S513, the color space is changed for each object. Next, in step S514, the document is updated, the process returns to step S501, and the same processing is performed again. If the current color space applied to each object is not changed, the process ends.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The second embodiment also has the configuration shown in FIGS. 1 to 4 as in the first embodiment.

  FIG. 6 is a flowchart illustrating a procedure in which the print operator executes the document processing program according to the second embodiment of the present invention on the print base.

  In the figure, in step S601, the print operator inputs a document for preflight check on a base PC (personal computer) and reads the document. In step S602, the input document is interpreted and analyzed.

  In step S603, an output device (printer) that outputs a document is selected. In step S604, the color conversion processing function of the selected printer is checked, and the information is acquired. Thereafter, the process proceeds to step S605, and it is determined whether or not the analyzed document includes two or more different color spaces. If it is determined that two or more different color spaces are included, one color space that has not been processed is selected (step S606), and then the process proceeds to step S607. If two or more different color spaces are not included, that is, if only one color space is included, the process proceeds to step S607 to perform processing for the one color space. In step S607, the color space to be processed is identified from among a plurality of types of color spaces.

  In step S608, based on the printer color conversion information acquired in step S604, it is determined whether the color space specified in step S607 can be replaced by the printer. If the specified color space can be replaced by the printer, the process proceeds to step S609, where the alternative color space is applied before the preflight check, and the process proceeds to step S610. If it is determined that the specified color space cannot be replaced by the printer, the process directly proceeds to step S610.

  In step S610, all objects in the document to which the specified color space is applied are selected, and the process further proceeds to step S611, where all the selected objects are filled with the same unique color different from other color spaces. . In step S612, it is determined whether processing has been completed for all color spaces included in the document. If there is a color space that has not been processed yet, the process returns to step S605, and the same processing is performed in the other color spaces. When the processing is completed for all the color spaces in the document, the process advances to step S613 to perform rendering. As shown in FIG. 7A, the rendering result is printed by a printer or previewed on a monitor (step S614), a preflight check is performed (step S615), and the result is shown in FIG. ) Print or display on the monitor as shown in. Also in the second embodiment, the preflight check confirms the color space of each object existing in the document, and the result is the same as in the first embodiment, as shown in FIG. The object color space is displayed in a color-coded state.

After performing the preflight check, the process proceeds to step S616, and when the current color space applied to each object is changed, the process proceeds to step S617, where the color space is changed for each object. In step S618, the document is updated, the process returns to step S601, and the same process is performed again. If the color space applied to each object is not changed, the process ends.
As described above, in the second embodiment, it is possible to determine at a glance what kind of color space each object in the document uses by printer output or monitor output.

  As described above, according to the present invention, it is possible to perform accurate color reproduction by performing a preflight check on a color space set by a user in a document before printing. In other words, a preflight check is performed to display what color space is applied to all objects in the document by preview or printing, and the color space included in the document and its application range are confirmed before printing. can do. Further, by providing a function that can change the color space of each object after the preflight check, the color setting can be changed quickly.

  Further, in the second embodiment, since the color conversion data of the printer is acquired, the color space to be replaced can be previewed even when the color space in the document is replaced by the printer. Therefore, the color space of the actually printed image can be confirmed accurately.
