Abstract

A method of forming an image and a crease on media by an image forming system includes forming a crease formation pattern on an impression media received by an impression member. The method also includes forming the image on an image forming blanket of an intermediate transfer member by a print unit. The method also includes pressing the media against the impression member by the image forming blanket to transfer the image onto the media and to establish contact with the crease formation pattern to form the corresponding crease on the media.

First claim

What is claimed is:

1. A method of forming an image and a crease on media by an image forming system, the method comprising:
forming a crease formation pattern on an impression paper received by an impression member, which crease formation pattern forms a crease in the media along which the media is to be folded;
forming the image on an image forming blanket of an intermediate transfer member by a print unit; and
pressing the media against the impression member by the image forming blanket to transfer the image onto the media and to establish contact with the crease formation pattern to form the corresponding crease on the media during the transfer of the image to the media.

2. The method of claim 1 , further comprising passing the impression paper and the media through a nip formed by the impression member and the image forming blanket of the intermediate transfer member.

3. The method of claim 1 , further comprising enabling selection of a predefined crease formation pattern to be formed on the impression paper.

4. The method of claim 1 , further comprising enabling generation of a customized crease formation pattern to be formed on the impression paper.

5. The method of claim 1 , in which forming a crease formation pattern on an impression paper is performed by a supplemental print unit separate from the print unit.

6. The method of claim 5 , further comprising:
receiving the media at the image forming blanket; and
receiving the impression paper at the supplemental print unit.

7. The method of claim 5 , in which:
the image forming blanket contacts one side of the media; and
the impression paper contacts an opposite side of the media.

8. The method of claim 1 , in which forming a crease formation pattern on an impression paper is performed by the print unit.

9. The method of claim 1 , in which forming a crease formation pattern on an impression paper comprises forming multiple layers of ink on top of each other to form the crease formation pattern.

10. The method of claim 1 , further comprising using a non-transitory computer-readable storage medium having computer executable instructions stored thereon for an image forming system to form an image and a crease on media, the instructions are executable by a processor to:
form a crease formation pattern on an impression paper received by an impression member, which crease formation pattern forms a crease in the media along which the media is to be folded;
form the image on an image forming blanket of an intermediate transfer member by a print unit; and
press the media against the impression member by the image forming blanket to transfer the image onto the media and to establish contact with the crease formation pattern to form the corresponding crease on the media during the transfer of the image to the media.

11. The method of claim 1 , in which forming the crease formation pattern comprises:
receiving the crease formation pattern on the image forming blanket; and
transferring the crease formation pattern to the impression paper.

12. The method of claim 11 , in which forming the crease formation pattern comprises:
forming a crease formation pattern on a photo-imaging cylinder (PIP) by the print unit; and
transferring the crease formation pattern from the PIP to the image forming blanket.

13. The method of claim 11 , in which the crease formation pattern is transferred to the impression paper when the media is not disposed in a nip formed by the impression member and the image forming blanket of the intermediate transfer member.

14. The method of claim 1 , in which forming a crease formation pattern on an impression paper received by an impression member comprises forming a subsequently-formed layer of ink having a smaller width on top of a previously-formed layer of ink having a greater width to form the crease formation pattern having a tapered end opposite to the impression paper on which the crease formation pattern is formed.

15. The method of claim 1 , further comprising:
receiving selection of a predefined crease formation pattern to be formed on the impression paper, the selected predefined crease formation pattern being used as the crease formation pattern that forms a crease in the media along which the media is to be folded.

16. The method of claim 15 , in which the crease formation pattern is directly formed on the impression paper.

17. The method of claim 16 , in which the crease formation pattern is printed on the impression paper by a supplemental print unit.

18. The method of claim 15 , in which the crease formation pattern is indirectly formed on the impression paper by the print unit.

19. The method of claim 15 , in which, during pressing the media against the impression member by the image forming blanket to transfer the image onto the media and forming the crease formation pattern to form the corresponding crease on the media, the impression paper is below the media.
