Abstract

In a color management system including a server and an image forming apparatus, the server stores information of a colorimetric sensor and paper information corresponding to the colorimetric sensor, obtains information of a colorimetric sensor mounted in the image forming apparatus, designates paper to use when executing a color adjustment process of the image forming apparatus, and, based on the stored paper information, selects a colorimetric sensor of the image forming apparatus corresponding to the designated paper. The image forming apparatus comprises causes a printer engine to print a chart on the designated paper in accordance with a color adjustment job for executing the color adjustment process, and measures a colorimetric value of the printed chart using the selected colorimetric sensor.

First claim

What is claimed is:

1. A color management system including a server and an image forming apparatus,
the server comprising
one or more first memories storing instructions; and
one or more first processors configured to execute the instructions to:
store information of a colorimetric sensor and paper information corresponding to the colorimetric sensor;
obtain information of a colorimetric sensor mounted in the image forming apparatus;
designate paper to use when executing a color adjustment process of the image forming apparatus; and
based on the stored paper information, select a colorimetric sensor of the image forming apparatus corresponding to the designated paper, and
the image forming apparatus comprises
at least one colorimetric sensor;
a printer engine;
one or more second memories storing instructions; and
one or more second processors configured to execute the instructions to:
cause the printer engine to print a chart on the designated paper in accordance with a color adjustment job for executing the color adjustment process; and
measure a colorimetric value of the printed chart using the selected colorimetric sensor.

2. The color management system according to claim 1 , wherein in the selection of the colorimetric sensor, the one or more first processors display a list of colorimetric sensors and allow a user to select a colorimetric sensor therefrom, and display a colorimetric sensor of the image forming apparatus that does not correspond to the designated paper in a state that the colorimetric sensor of the image forming apparatus is not able to be selected in the list.

3. The color management system according to claim 2 , wherein in the selection of the colorimetric sensor, the one or more first processors display a colorimetric sensor that is mounted in the image forming apparatus but unusable as unselectable in the list.

4. The color management system according to claim 1 , wherein in the selection of the colorimetric sensor, in a case where a colorimetric sensor corresponding to the designated paper is not mounted in the image forming apparatus, the one or more first processors select a manual colorimeter.

5. The color management system according to claim 1 , wherein in the selection of the colorimetric sensor, in a case where a plurality of colorimetric sensors corresponding to the designated paper are mounted in the image forming apparatus, the one or more first processors select the colorimetric sensor based on priorities of the plurality of colorimetric sensors.

6. The color management system according to claim 5 , wherein the one or more first processors are configured to further execute the instructions to set a colorimetry mode of the color adjustment process; and
the one or more first processors are configured to further execute the instructions to, in the selection of the colorimetric sensor, select a colorimetric sensor of the image forming apparatus based on priorities of the plurality of colorimetric sensors which accord with the set colorimetry mode.

7. The color management system according to claim 1 , wherein the one or more first processors are configured to further execute the instructions to obtain information of papers stored in a plurality of paper feed sources of image forming apparatus; and
the one or more first processors are configured to further execute the instructions to, in the designation of the paper, designate the paper to use from among papers stored in the plurality of paper feed sources of the image forming apparatus based on the obtained information.

8. An information processing apparatus operable to control a color adjustment process by an image forming apparatus having a plurality of colorimetric sensors, the information processing apparatus comprising
one or more memories storing instructions; and
one or more processors configured to execute the instructions to:
store information of a colorimetric sensor and paper information corresponding to the colorimetric sensor;
obtain information of the plurality of colorimetric sensors, which are mounted in the image forming apparatus;
designate paper to use when executing the color adjustment process of the image forming apparatus; and
based on the stored paper information, select a colorimetric sensor of the image forming apparatus corresponding to the designated paper.

9. The information processing apparatus according to claim 8 , wherein the one or more processors are configured to further execute the instructions to, in the selection of the colorimetric sensor, display a list of the plurality of colorimetric sensors and allow a user to select a colorimetric sensor therefrom, and display a colorimetric sensor of the image forming apparatus that does not correspond to the paper to use in a state that the colorimetric sensor of the image forming apparatus is not able to be selected in the list.

10. The information processing apparatus according to claim 9 , wherein the one or more processors are configured to further execute the instructions to, in the selection of the colorimetric sensor, display a colorimetric sensor that is mounted in the image forming apparatus but unusable as unselectable in the list.

11. The information processing apparatus according to claim 8 , wherein the one or more processors are configured to further execute the instructions to, in a case where a colorimetric sensor corresponding to the designated paper is not mounted in the image forming apparatus, in the selection of the colorimetric sensor, further select a manual colorimeter.

12. The information processing apparatus according to claim 8 , wherein the one or more processors are configured to further execute the instructions to, in a case where a plurality of colorimetric sensors corresponding to the designated paper to use are mounted in the image forming apparatus, in the selection of the colorimetric sensor, select the colorimetric sensor based on priorities of the plurality of colorimetric sensors.

13. The information processing apparatus according to claim 12 , wherein the one or more processors are configured to further execute the instructions to set a colorimetry mode of the color adjustment process, and
the one or more processors are configured to further execute the instructions to, in the selection of the colorimetric sensor, select a colorimetric sensor of the image forming apparatus based on priorities of the plurality of colorimetric sensors which accord with the set colorimetry mode.

14. The information processing apparatus according to claim 8 , wherein the one or more processors are configured to further execute the instructions to obtain information of papers stored in a plurality of paper feed sources of the image forming apparatus, and
the one or more processors are configured to further execute the instructions to, in the designation of the paper, designate the paper to use from among papers stored in the plurality of paper feed sources of the image forming apparatus.

15. An information processing apparatus operable to control a color adjustment process by an image forming apparatus having a plurality of colorimetric sensors, the information processing apparatus comprising
one or more memories storing instructions; and
one or more processors configured to execute the instructions to:
