Abstract

A method of providing a print representation of a document which, when printed, has at least one region the appearance of which is dependent on viewing conditions. The method comprises generating a representation of the document and then modifying the appearance of the at least one region to thereby simulate the appearance of the document when printed. This is achieved by animating the representation of the at least one region or at least partially combining the at least one region with an image.

a) generating a print preview representation of the document, said print preview representation being associated with the viewing conditions; and

b) animating the appearance of the at least one region in the print preview representation by applying a scattering filter to thereby simulate a change in the appearance of the printed document in accordance with a change in the viewing conditions.

2. The method according to claim 1, wherein the at least one region is to be printed using a spot color .

3. The method according to claim 2, wherein the spot color is formed from at least one of inks, dyes, toners, paints, films, lacquers and other printing substances having a reflective metallic appearance.

4. The method according to claim 1, wherein the method further comprises, in the processing system, animating the representation of the at least one region by moving the image.

b) input commands from a user;

c) movement of the user detected using a sensing system; and

,

d) signals from a motion sensing device.

6. The method according to claim 1, further comprising at least partially combining the at least one region with an image, wherein the image is at least one of:

a) indicative of a light source effect;

b) a time varying image;

c) captured using a camera system;

d) a simulation of a three dimensional environment including a number of objects; and

,

e) indicative of a reflection.

7. The method according to claim 1, wherein the method further comprises, in the processing system:

a) determining first parameters relating to the document; and

,

b) modifying the appearance of the region in accordance with the determined first parameters.

8. The method according to claim 7, wherein the method further comprises, in the processing system, determining the first parameters using at least one of:

a) the document content; and

,

b) the differences between the at least one region and other regions of the document.

9. The method according to claim 1, wherein the method further comprises, in the processing system:

a) determining second parameters relating to the image; and

,

b) modifying the appearance of the region in accordance with the determined second parameters.

10. The method according to claim 9, wherein the method further comprises, in the processing system, determining the second parameters based on at least one of:

a) objects within the image; and

,

b) at least one light source.

11. The method according to claim 1, wherein the method further comprises, in the processing system:

a) determining parameters relating to the combination of the image and the region; and

,

b) modifying the appearance of the region in accordance with the determined parameters.

12. The method according to claim 11, wherein the method further comprises, in the processing system, determining the parameters based on at least one of:

a) reflectivity;

b) diffusivity;

c) specular values; and

d) blooming.

13. The method according to claim 1, wherein the method further comprises, in the processing system, at least partially combining the at least one region with an image and animating the image by varying at least one of:

a) first parameters relating to the document; and

,

b) second parameters relating to the image; and

,

c) third parameters relating to the combination of the image and the region.

14. The method according to claim 1, wherein the method further comprises, in the processing system, at least partially combining the at least one region with an image and modifying the appearance of the at least one region by applying at least one of bumpiness, height variations, shading, warping and folding to at least part of a surface upon which the image is rendered to thereby simulate at least one of grain, texture, shininess, reflection, embossing, diffusion, scattering, and specular reflection.

15. The method according to claim 1, wherein the method further comprises, in the processing system, modifying regions other than the at least one region by at least one of blooming and bleeding of a bright portion of the at least one region into the other regions.

16. The method according to claim 1, wherein the at least one region is to be printed using at least one of:

a) a reflective substance;

b) a substance having a metallic appearance;

c) a substance that is at least partially translucent;

d) a substance whose appearance is dependent on the viewing angle; and

,

e) a temperature sensitive substance.

17. The method according to claim 1, wherein the viewing condition is at least one of:

c) the viewing orientation;

d) a temperature;

e) a time;

f) the position of the at least one region upon the printed document ;

g) the size of the spot color region,

h) the shape of a print medium;
