Abstract

An image forming apparatus is disclosed that performs a color conversion process in accordance with a color conversion setting set by an information processing apparatus that generates print data. The image forming apparatus includes a determination unit determining whether a valid color conversion setting has been performed by the information processing apparatus based on received print data; and a control unit controlling the color conversion process to be performed by the image forming apparatus based on a result determined by the determination unit.

Claims (21)

1. An image forming apparatus performing a color conversion process in accordance with a color conversion setting set by an information processing apparatus that generates print data, the image forming apparatus comprising:

a determination unit configured to determine whether a color conversion setting performed by the information processing apparatus is valid based on received print data, the received print data including information indicating whether the performed color conversion setting is valid or invalid; and

a control unit configured to control the color conversion process to be performed by the image forming apparatus based on a result determined by the determination unit.

2. The image forming apparatus according to claim 1 , wherein

the determination unit determines whether the valid color conversion setting has been performed by the information processing apparatus based on an analysis result of the print data.

3. The image forming apparatus according to claim 1 , wherein

the control unit comprises a switching unit configured to switch between a standard color conversion process and an extended color conversion process, the standard color conversion process being in accordance with a color conversion setting set by using a standard command, the extended color conversion process being in accordance with a color conversion setting set by using a vendor's own extended command, wherein

when the determination unit determines that the valid color conversion setting has been performed by the information processing apparatus, the switching unit switches the color conversion process to be performed by the image forming apparatus from the extended color conversion process to the standard color conversion process.

4. The image forming apparatus according to claim 1 , wherein

when at least one of a predetermined Page Description Language (PDL) command and a predetermined data pattern is included in the print data based on an analysis result of the print data, the determination unit determines that the valid color conversion setting has been performed by the information processing apparatus.

5. The image forming apparatus according to claim 3 , wherein

in the image forming apparatus, a default color conversion table where an input color value is a same as an output color value is set as a color conversion table to be used for the standard color conversion process, the color conversion table converting a color value from a device-independent input color value to a device-dependent output color value.

6. The image forming apparatus according to claim 5 , wherein

when the color conversion table is specified in the valid color conversion setting having been performed by the information processing apparatus, the image forming apparatus switches from the default color conversion table to the specified color conversion table and performs the standard color conversion process.

7. A color conversion control method to be used in an image forming apparatus performing a color conversion process in accordance with a color conversion setting set by an information processing apparatus that generates print data, the color conversion control method comprising:

determining whether a color conversion setting has been performed by the information processing apparatus based on received print data, the received print data including information indicating whether the performed color conversion setting is valid or invalid;

selecting, as the color conversion process to be performed, a standard color conversion process if the determination step determines that the color conversion setting performed by the information processing apparatus in the determination step is valid; and

selecting, as the color conversion process to be performed by the image forming apparatus, an extended color conversion process if the determination step determines that the color conversion setting performed by the information processing apparatus in the determination step is not valid, the extended color conversion process being a process that uses a color conversion setting set in accordance with color rendering information of the image forming device, the standard color conversion process being a process that uses a color conversion setting set in accordance with color rendering information of the information processing apparatus.

8. A non-transitory computer-readable recording medium comprising a program encoded and stored in a computer-readable format to cause a computer to execute a color conversion control method according to claim 7 .

9. An information processing apparatus having a printer driver configured to receive a color conversion setting through a user interface menu and generate print data including the received setting, wherein

the printer driver performs exclusive control between a color conversion setting of Image Color Management (ICM) of the information processing apparatus and a color conversion setting set by a vendor's own extended command in a manner such that the color conversion setting set by the vendor's own extended command is to be performed when the setting of the Image Color Management (ICM) is determined to be invalid ICM.
