Automated methods and systems for assessing and summarizing gamut requirements

1. A method of assessing color gamut requirements for a print job and a printing device, the method comprising:

receiving a print job;

producing, by a computing device, a color transformation for the print job using at least a color gamut error profile;

producing, by the computing device, result information based on the color transformation by:

determining an in-gamut color difference by color transforming the print job from an initial color space to a resulting color space using a color characterization profile to produce a color transformed print job,

color transforming the color transformed print job from the resulting color space back to the initial color space using an inverse color characterization profile to produce an output print job, and

determining an amount of color drift by comparing the print job to the output print job; and

providing the result information to a user.

2. The method of claim 1 wherein receiving a print job comprises:

receiving a print job comprising one or more objects, wherein the one or more objects comprise at least one of the following: an image, text, and a vector graphic.

4. The method of claim 1 wherein receiving a print job comprises receiving a print job comprising one or more objects, and wherein producing a color transformation comprises:

color transforming the one or more objects from an input color space into one or more resulting color spaces; and

rasterizing at least one color-transformed object.

5. The method of claim 1 wherein producing a color transformation comprises:

producing, by the computing device, a color transformation using a color profile and a color gamut error profile.

6. The method of claim 1 wherein producing result information further comprises:

automatically generating an image depicting a spatial position of a portion of the print job that is out-of-gamut based on the color gamut error profile.

7. The method of claim 1 wherein producing result information further comprises:

automatically generating an image depicting a spatial position of a portion of the print job that is out-of-gamut based on the color gamut error profile and a magnitude by which the portion of the print job is out-of-gamut.

8. The method of claim 1 , wherein determining an amount of color drift comprises:

determining one or more portions of the output print job that differ from the print job; and

for at least one of the portions, determining an amount by which the portion differs from the print job.

9. The method of claim 8 , wherein the amount by which the portion differs from the print job is represented by a scalar value.

10. A system for assessing color gamut requirements for a print job and a printing device, the system comprising:

a processor; and

a processor readable storage medium in communication with the processor,

wherein the processor readable storage medium contains one or more programming instructions for performing a method of assessing color gamut requirements for a print job and a printing device, the method comprising:

receiving a print job,

producing a color transformation for the print job using at least a color gamut error profile,

producing result information based on the color transformation by:

determining an in-gamut color difference by color transforming the print job from an initial color space to a resulting color space using a color characterization profile to produce a color transformed print job,

color transforming the color transformed print job from the resulting color space back to the initial color space using an inverse color characterization profile to produce an output print job, and

determining an amount of color drift by comparing the print job to the output print job, and

providing the result information to a user.

11. The system of claim 10 wherein the one or more programming instructions for receiving a print job comprise one or more programming instructions for receiving a print job comprising one or more input color spaces, wherein the one or more programming instructions for producing a color transformation comprise one or more programming instructions for producing a color transformation for each input color space using at least a color gamut error profile, and wherein the one or more programming instructions for producing result information comprise one or more programming instructions for producing result information based on the one or more color transformations.

12. The system of claim 11 , wherein the one or more programming instructions for determining an amount of color drift comprise one or more programming instructions for:

determining one or more portions of the output print job that differ from the print job; and

for at least one of the portions, determining an amount by which the portion differs from the print job.

13. The system of claim 12 , wherein the amount by which the portion differs from the print job is represented by a scalar value.

14. The system of claim 10 wherein the one or more programming instructions for receiving a print job comprise one or more programming instructions for receiving a print job comprising one or more objects, and wherein the one or more programming instructions for producing a color transformation comprise one or more programming instructions for:

color transforming the one or more objects from an input color space into one or more resulting color spaces; and

rasterizing at least one color-transformed object.

15. The system of claim 10 wherein the one or more programming instructions for producing a color transformation comprise one or more programming instructions for:

producing a color transformation using a color profile and a color gamut error profile.

16. The system of claim 10 wherein the one or more programming instructions for producing result information comprise one or more programming instructions for:

identifying out-of-gamut statistics based on the color transformation.

17. The system of claim 10 wherein the one or more programming instructions for producing result information comprise one or more programming instructions for:

determining one or more colors of the print job that are out-of-gamut based on the color gamut error profile; and

for at least one color, determining an amount by which the color of the print job is out-of-gamut.
