Image formation apparatus and image formation method

1. An image formation apparatus for forming a three dimensional print image on a recording medium by an image of three dimensional printing material and an image of color material in accordance with image data, comprising:

designation means for designating a three dimensional print region using three dimensional printing material and a non-three dimensional print region, with regard to the image data; and

image processing means for performing different color conversions on the image data depending on the three dimensional print region and the non-three dimensional print region designated by the designation means.

2. An image formation apparatus according to claim 1 , wherein the image processing means has a color conversion means for changing the color conversion according to the amount of three dimensional printing material transferred on the recording medium.

3. An image formation apparatus according to claim 2 , wherein the color conversion means includes:

a coloration data table for storing the coloration data of the color material according to amount of three dimensional printing material transferred on the recording medium; and

color conversion means for using the coloration data table as a base for separately performing a color conversion on the image data depending on the three dimensional print region and the non-three dimensional print region so that the three dimensional print region and the non-three dimensional print region have identical coloration.

4. An image formation apparatus for forming a three dimensional print image on a recording medium by an image of three dimensional printing material and an image of color material in accordance with image data, comprising:

designation means for designating a three dimensional print region using three dimensional printing material and a non-three dimensional print region, with regard to the image data; and

image processing means for performing a color conversion on the image data so that the three dimensional print region and the non-three dimensional print region designated by the designation means have identical color gamut.

5. An image formation method for forming a three dimensional print image on a recording medium by an image of three dimensional printing material and an image of color material in accordance with image data, comprising the steps of:

designating a three dimensional print region using three dimensional printing material and a non-three dimensional print region with regard to the image data; and

performing different color conversions on the image data depending on the three dimensional print region and the non-three dimensional print region.

6. An image formation method according to claim 5 , wherein amount of the color conversion is changed according to amount of three dimensional printing material transferred on the recording medium.

7. An image formation method according to claim 6 , further comprising the steps of:

preparing a coloration data table;

storing coloration data of the color material in the coloration data table according to the amount of three dimensional printing material transferred on the recording medium; and

performing separate color conversion on the image data depending on the three dimensional print region and the non-three dimensional print region so that the three dimensional print region and the non-three dimensional print region have the identical coloration.

8. An image formation method for forming a three dimensional print image on a recording medium by an image of three dimensional printing material and an image of color material in accordance with image data, comprising the steps of:

designating a three dimensional print region using three dimensional printing material and a non-three dimensional print region with regard to the image data; and

performing a color conversion on the image data so that the three dimensional print region and the non-three dimensional print region have identical coloration.
