Abstract

Provided is a printing profile setting device that is characterized in including:storage means for storing a profile of a reference printing device and reference patch data; printing control means for having a target printing device printed a target patch based on the reference patch data; data capture means for capturing, via an image reading device, reference color data representing a printing color of a reference patch that is printed by the reference printing device based on the reference patch data, and target color data representing a printing color of the target patch; and setting means for comparing the reference color data and the target color data in the same color space, and based on a comparison result, setting a profile derived by correcting a profile of the reference printing device as a profile of the target printing device.

Claims

1. A printing profile setting device, comprising:

storage means for storing a profile of a reference printing device and reference patch data;

printing control means for having a target printing device printed a target patch based on the reference patch data;

data capture means for capturing, via an image reading device, reference color data representing a printing color of a reference patch that is printed by the reference printing device based on the reference patch data, and target color data representing a printing color of the target patch; and

setting means for comparing the reference color data and the target color data in the same color space, and based on a comparison result, setting a profile derived by correcting a profile of the reference printing device as a profile of the target printing device.

2. The printing profile setting device according to claim 1, wherein

the data capture means captures the reference color data and the target color data solely via the image reading device.

3. The printing profile setting device according to claim 2, wherein

the data capture means has the image reading device read at a time the reference patch and the target patch.

4. The printing profile setting device according to claim 1, wherein

the setting means compares the reference color data and the target color data in a color space that is standardized separately from the image reading device.

5. The printing profile setting device according to claim 1, wherein

the setting means specifies the target color data representing a color most similar to a color represented by any of the reference color data based on the comparison result, and sets, as the profile of the target printing device, a profile corresponding to a mapping as a result of combining a mapping replacing a first output value of the profile of the reference print device corresponding to the reference color data with a second output value of the profile of the reference printing device corresponding to the specified target color data, and a mapping corresponding to the profile of the reference printing device.

6. A printing profile setting system, comprising:

an image reading device for reading an optical image of a reference patch printed by a reference printing device based on reference patch data, and an optical image of a target patch printed by a target printing device based on the reference patch data; and

a printing profile setting device, including;

storage means for storing a profile of the reference printing device and the reference patch data;

printing control means for having the target printing device printed the target patch based on the reference patch data;

data capture means for capturing, via the image reading device, reference color data representing a printing color of the reference patch, and target color data representing a printing color of the target patch; and

setting means for comparing the reference color data and the target color data in the same color space, and based on a comparison result, setting a profile derived by correcting a profile of the reference printing device as a profile of the target printing device.

7. A printing profile setting method, comprising the steps of:

having a target printing device printed a target patch based on reference patch data;

reading a reference patch printed by a reference printing device based on the reference patch data and the target patch, and capturing reference color data representing a printing color of the reference patch and target color data representing a printing color of the target patch; and

comparing the reference color data and the target color data in the same color space, and based on a comparison result, setting a profile derived by correcting a profile of the reference printing device as a profile of the target printing device.

8. A printing profile setting program product for use with a computer operable with:

storage means for storing a profile of a reference printing device and reference patch data;

printing control means for having a target printing device printed a target patch based on the reference patch data;

data capture means for capturing, via an image reading device, reference color data representing a printing color of a reference patch that is printed by the reference printing device based on the reference patch data, and target color data representing a printing color of the target patch; and

setting means for comparing the reference color data and the target color data in the same color space, and based on a comparison result, setting a profile derived by correcting a profile of the reference printing device as a profile of the target printing device.
