Abstract

A light-blocking object processing section produces first and second light-blocking objects to be formed on the front and back surfaces of a print medium, respectively. A first image object is formed on the first light-blocking object and a second image object is formed on the second light-blocking object. If the first and second image objects should be formed in first and second areas, respectively, and the first and second areas defining an overlapping area in which the first image object overlaps the second image object, then the light-blocking object processing section performs one of a first process in which the thickness of the first and second light-blocking objects is smaller in the overlapping area than in a third area outside the overlapping area and a second process in which one of the first and second light-blocking objects is not formed.

First claim

What is claimed is:

1. An image data processing apparatus, comprising:
a light-blocking object processing section configured to produce
a first light-blocking object on which a first image object is formed and which is formed on a front surface of a medium, and
a second light-blocking object on which a second image object is formed and which is formed on a back surface of the medium,

if the first image object is to be formed in a first area, the second image object is to be formed in a second area, and the first area and the second area define an overlapping area in which the first image object overlaps the second image object with the medium therebetween, then the light-blocking object processing section performs one of
a first process in which the first and second light-blocking objects have a thickness smaller in the overlapping area than that of the first and second light-blocking objects in a third area outside the overlapping area, and
a second process in which one of the first and second light-blocking objects is not formed.

2. An image data processing apparatus, comprising:
an image object producing section configured to produce
a first image object formed on a front surface of a medium, and
a second image object formed on a back surface of the medium;

a light-blocking object processing section configured to produce
a first light-blocking object formed as an underlayer of the first image object and is in a first area between the first image object and the medium, and
a second light-blocking object which is formed as an underlayer of the second image object and is in a second area between the second image object and the medium; and

an overlapping area determining section configured to determine
an overlapping area in which the first area and the second area overlap each other with the medium between the first area and the second area, and
a third area in which the first area and the second area do not overlap each other,

wherein the light-blocking object processing section produces the first light-blocking object and the second light-blocking object so that at least one of the first light-blocking object and the second light-blocking object has a first selected thickness in the overlapping area that is smaller than a second selected thickness thereof in the third area.

3. The image data processing apparatus according to claim 2 , wherein the image object producing section is further configured to produce
a first item of image object data that describes the first image object, and
a second item of image object data that describes the second image object.

4. The image data processing apparatus according to claim 3 , wherein the light-blocking object processing section includes
a print area determining section configured to determine the first area and the second area; and
a thickness adjusting section configured
to set a first portion of the first light-blocking object and a first portion of the second light-blocking object, which each fall in the overlapping area, to each have the first selected thickness, and
to set a second portion of the first light-blocking object and a second portion of the second light-blocking object, which each fall in the third area, to each have the second selected thickness.

5. The image data processing apparatus according to claim 4 , wherein the first selected thickness is half the second selected thickness.

6. The image data processing apparatus according to claim 4 , wherein the first image object is within the first area and the second image object is within the second area.

7. The image data processing apparatus according to claim 4 , wherein the first area has substantially the same shape and size as the first image object, and the second area has substantially the same shape and size as the second image object.

8. The image data processing apparatus according to claim 4 , wherein a sum of the first selected thickness of the first light-blocking object and the first selected thickness of the second light-blocking object is substantially equal to each of the second selected thicknesses of the first and second light-blocking objects that fall in the third area.

9. The image data processing apparatus according to claim 4 , wherein the second selected thickness is a minimum required thickness so that the first or second image object formed on one of the front and back surfaces of the medium cannot be seen through the other of the front and back surfaces of the medium.

10. The image data processing apparatus according to claim 2 , wherein the light-blocking object processing section further includes a blocking object mottling section configured to delete first pixels of the first light-blocking object and second pixels of the second light-blocking object, the pixels falling in the overlapping area and the first pixels and the second pixels being positioned one over the other.

11. The image data processing apparatus according to claim 2 ,
wherein the first light-blocking object is formed in an area substantially congruent to an area in which the first image object is formed,
wherein the second light-blocking object is formed in an area substantially congruent to an area in which the second image object is formed.

12. The image data processing apparatus according to claim 2 , wherein the light-blocking object processing section produces the first and second light-blocking objects such that one of the first and second light-blocking objects has the first selected thickness which is smaller than a thickness of the other of the first and second light-blocking objects.

13. An image data processing apparatus, comprising:
a light-blocking object processing section configured to produce
a first light-blocking object that is as an underlayer of a first image object formed on a front of a medium, the first light-blocking object being in a first area between the first image object and the medium, and
a second light-blocking object which is formed as an underlayer of a second image object formed on a rear surface of the medium, the second light-blocking object being in a second area between the second image object and the medium; and

an overlapping area determining section configured to determine
an overlapping area in which the first area and the second area overlap each other with the medium between the first area and the second area, and
a third area in which the first area and the second area are formed but do not overlap each other,

wherein the light-blocking object processing section produces the first light-blocking object and the second light-blocking object so that a thickness of one of the first light-blocking object and the second light-blocking object is smaller in the overlapping area than in the third area.
