Abstract

Provided is a technique that can suitably form a cut line. According to one embodiment, an image forming device includes a line information generation unit and an image forming unit. The line information generation unit generates line information representing a cut line to cut out a main image formed on a recording medium. The image forming unit forms the main image with a non-decolorable material on the recording medium and forms the cut line represented by the line information with a decolorable material on the recording medium. The line information generation unit changes a level of curving of a curve included in the cut line, according to the recording medium.

Claims (44)

1. An image forming device, comprising:

a line information generation component configured to generate line information representing a cut line to cut out a main image formed on a recording medium;

an image forming component configured to form the main image with a non-decolorable material on the recording medium and form the cut line represented by the line information with a decolorable material on the recording medium, wherein

the line information generation component changes a level of curving of a curve included in the cut line, according to the recording medium.

2. The image forming device according to claim 1 , wherein the line information generation component makes the level of curving of the curve included in the cut line gentler as a thickness of the recording medium becomes greater.

3. The image forming device according to claim 1 , wherein the line information generation component makes the level of curving of the curve included in the cut line gentler as a hardness of the recording medium becomes greater.

4. The image forming device according to claim 1 , wherein

the line information generation component forms a closed curve that surrounds the main image and that forms an area where a predetermined shape is formed, as the cut line.

5. The image forming device according to claim 1 , wherein

the line information generation component forms a closed curve having a shape of an area formed by a cut line similar to a shape of the main image.

6. The image forming device according to claim 1 , further comprising:

an image processing component configured to determine whether the main image is a convex image or a concave image.

7. The image forming device according to claim 1 , wherein

the non-decolorable material has multiple colors.

8. An image forming method, comprising:

generating line information representing a cut line to cut out a main image formed on a recording medium;

forming the main image with a non-decolorable material on the recording medium and forming the cut line represented by the line information with a decolorable material on the recording medium; and

changing a level of curving of a curve included in the cut line, according to the recording medium.

9. The image forming method according to claim 8 , further comprising:

making the level of curving of the curve included in the cut line gentler as a thickness of the recording medium becomes greater.

10. The image forming method according to claim 8 , further comprising:

making the level of curving of the curve included in the cut line gentler as a hardness of the recording medium becomes greater.

11. The image forming method according to claim 8 , further comprising:

forming a closed curve that surrounds the main image and that forms an area where a predetermined shape is formed, as the cut line.

12. The image forming method according to claim 8 , further comprising:

forming a closed curve having a shape of an area formed by a cut line similar to a shape of the main image.

13. The image forming method according to claim 8 , further comprising:

determining whether the main image is a convex image or a concave image.

14. The image forming method according to claim 8 , wherein

the non-decolorable material is black toner.

15. An image forming device, comprising:

a line information generation component configured to generate line information representing a cut line to cut out a main image formed on a recording medium;

an image forming component configured to form the main image with a black toner on the recording medium and form the cut line represented by the line information with a decolorable material on the recording medium, wherein

the line information generation component changes a level of curving of a curve included in the cut line, according to the recording medium.

16. The image forming device according to claim 15 , wherein

the line information generation component makes the level of curving of the curve included in the cut line gentler as a thickness of the recording medium becomes greater.

17. The image forming device according to claim 15 , wherein

the line information generation component makes the level of curving of the curve included in the cut line gentler as a hardness of the recording medium becomes greater.

18. The image forming device according to claim 15 , wherein

the line information generation component forms a closed curve that surrounds the main image and that forms an area where a predetermined shape is formed, as the cut line.

19. The image forming device according to claim 15 , wherein

the line information generation component forms a closed curve having a shape of an area formed by a cut line similar to a shape of the main image.

20. The image forming device according to claim 15 , further comprising:

an image processing component configured to determine whether the main image is a convex image or a concave image.
