Abstract

The management of color presented at end point devices such as a display or printer is based on the implementation of a Color Management Resource (CMR). A CMR is an architected resource stored accessibly to a print server or other processor that is used to carry all of the color management information required to render a print file, document, page, or data object.

Claims

1. A method of operating an Advanced Function Presentation (AFP) system comprising:

creating an (AFP) document for outputting comprising;

adding a component to the AFP document;

adding a color management resource (CMR) to the AFP document;

adding an association which associates the component with the CMR to the AFP document, the CMR comprising details for use when rendering colors of at least part of the component during its output; and

adding a command to the AFP document for invoking the associated CMR during output of the at least part of the component wherein the command specifies a scope for invocation of the CMR; and

providing the AFP document for output at a target device.

2. The method of claim 1 wherein the details relate to one of a color conversion, a link color conversion, a halftone screen, and a calibration curve.

3. The method of claim 1 wherein the CMR is one of an instruction CMR which defines processing which is to be done on the at least part of the component, and an audit CMR which defines processing which has been done on the at least part of the component.

4. A data processing apparatus defining an Advanced Function Presentation (AFP) system comprising:

a document creator for creating an AFP document for outputting, the document creator comprising;

a component adder for adding a component to the AFP document;

an association adder for adding an association that associates the component with a color management resource (CMR) to the AFP document;

the CMR comprising details for use when rendering colors of at least part of the component during its output; and

a command adder for adding a command to the AFP document for invoking the associated CMR during output of the at least part of the component; and

a document provider for providing the AFP document for output at a target device.

5. The apparatus of claim 4 further comprising:

a CMR adder for adding the CMR to the AFP document.

6. The apparatus of claim 4 wherein the details relate to one of a color conversion, a link color conversion, a halftone screen, and a calibration curve.

7. The apparatus of claim 4 wherein the CMR is one of an instruction CMR which defines processing which is to be done on the at least part of the component, and an audit CMR which defines processing which has been done on the at least part of the component.

8. An Advanced Function Presentation (AFP) system defining an article of manufacture comprising a program storage medium readable by a computer, the medium tangibly embodying one or more programs of instructions executable by a computer to perform a method comprising:

creating an AFP document for outputting comprising;

adding a component to the AFP document;

adding an association which associates the component with a color management resource (CMR) to the AFP document,

the CMR comprising details for use when rendering the colors of at least part of the component during its output; and

adding a command to the AFP document for invoking the associated CMR during output of the at least part of the component; and

providing the AFP document for output at a target device.

9. The article of manufacture of claim 8 wherein creating a document for output further comprises:

adding the CMR to the AFP document.

10. The article of manufacture of claim 8 wherein the details relate to one of a color conversion, a link color conversion, a halftone screen, and a calibration curve.

11. The article of manufacture of claim 8 wherein the CMR is one of an instruction CMR which defines processing which is to be done on the at least part of the component, and an audit CMR which defines processing which has been done on the at least part of the component.

12. A method of operating an Advanced Function Presentation (AFP) system comprising the steps of:

producing computer executable program code; and

providing the program code to be deployed and executed on a computer system;

the program code comprising instructions for;

creating an AFP document for outputting comprising;

adding a component to the AFP document; and

adding an association which associates the component with a color management resource (CMR) to the AFP document, the CMR comprising details for use when rendering the colors of at least part of a component during its output; and

providing the AFP document for output at a target device;

wherein the details relate to at least one of a color conversion, a link color conversion, a halftone screen, and a calibration curve;

wherein the instructions for creating the AFP document for output comprises further instructions for adding a command to the AFP document; and

wherein the command invokes the associated CMR during output of the at least part of a component.

13. The method of claim 12, the instructions for creating a document for output comprising further instructions for:

adding the CMR to the AFP document.

14. The method of claim 12 wherein the CMR is one of an instruction CMR which defines processing which is to be done on the at least part of the component, and an audit CMR which defines processing which has been done on the at least part of the component.
