comparing the target information from the first object with the target information from the second object to determine whether the first object is optimized for the second halftone screening parameter of the second target device; and

providing a warning message to a user when the first object is not optimized for the second halftone screening parameter of the second target device, the warning message being provided before retargeting the first object to be optimized for the second halftone screening parameter of the second target device and before outputting the first object and the second object.

2. The method of claim 1 , wherein the determining the target information from the first object and the second object comprises performing an analysis of the first object and the second object.

3. The method of claim 1 , wherein the database is a document repository.

4. The method of claim 1 , wherein the target information further comprises at least one of color space information, presence and type of error diffusion, halftone dot shape, number and frequency of dot cells, inherent tone reproduction curves, and marking technology.

5. The method of claim 1 , further comprising retargeting the first object to be optimized for the second target device.

6. The method of claim 1 , further comprising

performing at least one preflight operation according to a preflighting tool or application on the first object or the second object,

wherein the first object and the second object include at least one of a binary raster image and a targeted contone raster image.

7. A compound document analysis and target tracking method for a computer, the computer executing the steps of:

providing a compound document that comprises a first object and a second object, the first object and the second objects being at least one of a page description language file and a raster image, the first object being optimized for a first halftone screening parameter of a first target device and the second object being optimized for a second halftone screening parameter of a second target device, each target device being a specific marking device;

analyzing the first object and the second object to determine target information stored within the first object and target information stored within the second object;

saving the target information specific to halftone screening parameters of each object and the processing history of each object inside at least one of (1) a targeting information tag or label corresponding to the raster image, (2) the compound document or (3) a database, the target information being print processing information for print processing each object at a specific target device;

comparing the target information from the first object with the target information from the second object to determine whether the first object is optimized for the second halftone screening parameter of the second target device;

providing a warning message to a user when the first object is not optimized for the second halftone screening parameter of the second target device;

in response to input by the user in response to the warning message, performing at least one of:

aborting the inclusion into the compound document of the first object or the second object,

retargeting the first object to be optimized for the second halftone screening parameter of the second target device, and

overriding the warning message and continuing with processing of the compound document.

8. The method of claim 7 , wherein each object is at least one of a binary raster image, a targeted contone raster image, and a targeted page description language file.

9. The method of claim 7 , further comprising

comparing the target information from a new object added to the compound document to the target information from the first object and the target information from the second object at the time the new object is added to the compound document.

10. The method of claim 9 , wherein the new object is at least one of a binary raster image, a targeted contone raster image, and a targeted page description language file.

11. The method of claim 7 , further comprising

setting a target device of the compound document as being the target device of the second object, the second object being the initial object added to the compound document.

12. The method of claim 7 , wherein the saving the target information comprises saving the target information in at least one of a part of a format of the compound document and a document repository.

13. A document target tracking system, comprising:

a controller;

an input module controlled by the controller and that inputs a document comprising a first object being optimized for a first halftone screening parameter of a first target device and a second object being optimized for a second halftone screening parameter of a second target device, each target device being a specific marking device, the first object and the second objects being at least one of a page description language file and a raster image;

a processing module controlled by the controller and that determines target information stored within the first object and target information stored within the second object;

a memory that stores the target information specific to halftone screening parameters of each object and the processing history of each object inside at least one of (1) a targeting information tag or label corresponding to the raster image, (2) the compound document or (3) a database, the target information being print processing information for print processing the object at a specific target device; and

an output module controlled by the controller and that outputs the document to a processing device,

wherein the controller controls a comparison of the target information from the first object and the target information from the second object to determine whether the first object is optimized for the second target device, and

the controller provides a warning message to a user when the first object is not optimized for the second halftone screening parameter of the second target device, the warning message being provided before retargeting the first object to be optimized for the second halftone screening parameter of the second target device and before outputting the document.

14. A marking device, comprising the document target tracking system of claim 13 .

15. A page description language file target tracking method for a computer, the computer executing the steps of:

determining target information stored within a page description language file that comprises a raster image, the page description language file and the raster image being optimized for a halftone screening parameter of a target device;
