Indicates that the input profile and the output profile specified by the user in the detailed color settings described above match on the list of profile management data sent from the color image forming apparatus (700) by the color profile data list request command. The input profile and the output profile that are specified to have a profile name are compared with each other.

If there is no same input / output profile in the color image forming apparatus (700), the color profile is registered in the color image forming apparatus.

<Registration of Color Profile in Color Image Forming Apparatus> When the printer driver (461) determines that the specified profile does not exist in the color image forming apparatus (700) by the above procedure, <color Perform the process specified by the <Automatic profile update> check box on the Detailed Settings> dialog.

<When Automatic Profile Update is OFF>
Check box for <Automatic profile update> is OFF
In the case of, the information indicating that the designated input profile does not exist on the printer side is displayed in the message information display portion of the information (210-8). At this time, when the print process is executed, the default input profile or output profile in the color image forming apparatus (700) is used.

<When Automatic Profile Update is ON><
When the check box of "Automatic profile update>" is ON, the printer driver (461) is connected to the color image forming apparatus (700) to which the target printer unit is connected, to the color image forming apparatus. The printer name and model name uniquely determined on the network of the printer section of the digital color copying machine, and the color profile data selected by the user and not existing in the color image forming apparatus (700) The corresponding profile management data and profile actual data portion in the profile list management data (100) are set in the communication packet of the color profile data registration command that is uniquely determined, and designated through the network controller (420). Has a unique network identifier Send to color image forming apparatus (700).

The main controller (710) of the color image forming apparatus (700) analyzes the communication packet of the color profile data registration command sent via the network controller (740) and sends it to the profile manager (751). , Instruct to register profile data from the client.

The profile manager (751) checks the target printer name from the above communication packet, and the client requests registration in order from the profile management data (INC-001) part for the total number of input / output profiles. Search for profile management data with the same name and profile identifier, and confirm that they are not the same.

By the above search processing, the color profile data from the client is transferred to the color image forming apparatus (70).
If not registered in 0), the profile manager (751) determines whether it is an input profile or an output profile from the <profile type> in the profile management data of the client set in the communication packet, and the corresponding profile Increment the total number.

Further, in the communication packet,
Actual profile data part> Profile data is copied to the actual profile data part (303).

If the color profile data specified by the user on the client is not in the color image forming apparatus (700) to which the specified printer is connected, the series of processes causes the color profile data on the client to be changed to color. It is registered in the profile list management data (300) section in the image forming apparatus.

As a result, when the color profile data is registered in the color image forming apparatus (700),
Network controller of color image forming apparatus (74
0 is the client computer (4
00), the printer driver (461) on the client side registers the profile in the color image forming apparatus (700) on the printer side by sending back an identifier indicating that the registration process has been successful. I can confirm that.

The printer driver (461) determines that the host profile list management data (100) indicates that the color profile data registration command has been successfully processed.
The <registration destination printer identifier> of the target profile management data in is to write the network identifier of the color image forming apparatus (700) that has registered the profile, and the color image forming apparatus of the printer for which this profile is designated ( It becomes the flag registered in 700).

<Printer Driver PDL Code Generation Processing> After setting each parameter on the dialog of the printer driver (461) described above, the user presses the print execution button (200-8) with an instruction device such as a mouse. When pressed, the printer driver (461) requests the graphic manager (413) to output data from the user application. The application data of the user is matched with the standardized graphic drawing command via the graphic manager (413), and the printer driver (461) converts the graphic drawing command into a PDL code.

<Incorporating Color Profile Setting Command into PDL Data> Printer Driver (461)
Before converting the graphic command from the graphic manager (413) to PDL, the profile names of the input profile and the output profile specified by the user on the dialog are input profile uniquely determined by the PDL command. And the output profile specification command as parameters of the PDL color conversion processing portion of the PDL operator.

The command / operator for setting the color profile is written in the stream in the PDL. The profile data specified by the user is already registered in the color image forming apparatus (700) by the printer driver at this time, and it is not necessary to incorporate the actual data portion of the profile into the PDL stream each time. Therefore, the efficiency of PDL transmission will be improved.

<Conversion Processing to PDL Data> The printer driver (461) continues to convert the graphic command from the graphic manager (413) to PDL, stream the PDL, and at any time, the spooler (4
60). In this spooler, the PDL stream converted by the printer driver is temporarily stored internally.

The stored PDL stream data is sent to a color image forming apparatus (700) having a printer, which is uniquely determined in advance by a printer driver, through a network controller.
It is divided into a plurality of communication packets and transmitted.

A print execution command, which is uniquely determined in advance, is set in this communication packet, and the data portion of the PDL is set by being divided into a plurality of packets, and a color image is formed via the network. Transmitted to the device (700).

<PDL Code Registration Processing in Color Image Forming Apparatus> The main controller (710) of the color image forming apparatus (700) uses the network controller (740) to execute the above-mentioned printing from the client that has executed the print job. The execution communication packet is obtained, and it is identified that the packet is a command of <print execution> request. Then, the main controller extracts the data portion of the PDL from the plurality of communication packets containing the PDL data that is transmitted thereafter, and the PDL data is stored in the hard disk (742) via the hard disk controller (741). To register.

<Rasterization process of PDL code in color image forming apparatus> Here, the main controller (710) instructs the PDL rasterizer (761) to convert the raster image from the PDL code previously registered in the hard disk. Execute the process to create.

The PDL rasterizer (761) reads the PDL code from the hard disk at any time, and the PDL code is read.
When the code is analyzed and specific color processing is required, the image data rasterized by the PDL rasterizer is color processed through the color processing controller (780), and further, through the memory management controller (720). Image data rasterized from the PDL code is finally registered in the raster image memory (760).

<Extraction of profile setting command in PDL code> In the process of analyzing the PDL code, the PDL rasterizer (761) is described in the PDL code by the printer driver on the client according to the above-mentioned procedure. Profile command> and its parameter <input profile name>. Similarly, <output profile command> described on the PDL code and P of its parameter <output profile name>.
Detect DL code.

Further, the PDL rasterizer instructs the profile manager (751) to specify the profile of each input / output from the profile name designation on the PDL code detected by the above-mentioned procedure.
It is checked whether it is registered in the profile list management data (300) in the color image forming apparatus (700).

<Input / output profile setting of color processing controller> The profile manager (751) uses the profile management data (INC-001) in the profile list management data (300) with which the profile name specified in the PDL by the client matches. ) (INC-
002) in order for the total number of input profiles and the total number of output profiles, and if there is matching profile management data, the profile manager (75
In 1), the profile type in the corresponding profile management data and the profile actual data part are set in the color processing controller as the input / output profile of the color processing controller.

At this time, P specified by the client
The profile name, which is a parameter of the command operator on the DL, may be a key code uniquely predetermined on the print system, and it is also possible to compare whether the profile managers match.

When no profile is specified on the PDL code, profile data uniquely determined in advance is set as a default in the color processing controller section.

<Output from Digital Color Copier> In this way, the image data rasterized from the PDL code is converted into a standardized color space by a series of input profiles via the color conversion controller, and further, The conversion to the printer color space is performed according to the output profile, and the image data converted from the PDL data according to the profile is registered page by page in the raster image memory (760). When the image for one page is created, the main controller (710) is uniquely determined for the digital color copying machine (1000) having a printer unit via the color digital interface (790). A print execution command is sent, the image data for one page that has already been created is similarly sent via the color digital interface, and output processing is performed by the printer section of the digital color copying machine.

This color image forming apparatus (700) is incorporated in the above-mentioned digital color copying machine and can be used as an integrated one. One digital color copying machine is directly connected to the network. It is also possible to connect and process PDL data from the client as a printer.

As described above, the printer driver does not incorporate the color profile data into the PDL data created on the client host each time, but downloads the profile data into the printer controller at a specific timing and registers the profile data. By incorporating the segregated weaving code in the PDL, it becomes possible to reduce the size of output data from the client and centralize the management of the profile.
