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. An image forming system, comprising:
an impression member that receives impression paper;
a print unit to selectively form an image;
an intermediate transfer member having an image forming blanket;
a crease selection module to enable selection of a predefined crease formation pattern to be formed on the impression paper, which crease formation pattern forms a crease in the media, along which the media is to be folded; and
the image forming blanket to press media against the impression member to transfer the image onto the media and to establish contact with a crease formation pattern to form a corresponding crease on the media.

2. The image forming system according to claim 1 , wherein the crease is formed on the media during the transfer of the image from the image forming blanket to the media.

3. The image forming system according to claim 1 , wherein the print unit comprises: a plurality of binary ink developers.

4. The image forming system according to claim 1 , further comprising a supplemental print unit to form the crease formation pattern on the impression paper.

5. The image forming system according to claim 4 , wherein the crease is formed on the media during the transfer of the image from the image forming blanket to the media.

6. The image forming system according to claim 4 , wherein the print unit comprises: a plurality of binary ink developers.

7. The image forming system according to claim 4 , wherein the supplemental print unit comprises: an inkjet print head to eject ink onto the impression paper to form the crease formation pattern thereon.

8. The image forming system according to claim 4 , wherein the supplemental print unit comprises a binary ink developer.

9. A method of forming an image and a crease on media by the image forming system of claim 1 , the method comprising:
forming the image on the image forming blanket of the intermediate transfer member by the print unit.

10. The method according to claim 9 , wherein the forming a crease formation pattern on an impression paper received by an impression member further comprises: forming multiple layers of ink on top of each other to form the crease formation pattern.

11. The method according to claim 10 , wherein the forming multiple layers of ink on top of each other to form the crease formation pattern further 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.

12. The method according to claim 9 , wherein the forming a crease formation pattern on an impression paper received by an impression member further comprises: directly forming the crease formation pattern on the impression paper by a supplemental print unit.

13. The method according to claim 9 , wherein the forming a crease formation pattern on an impression paper received by an impression member further comprises: indirectly forming the crease formation pattern on the impression paper by the print unit.

14. The method according to claim 13 , wherein the indirectly forming the crease formation pattern on the impression paper by the print unit further comprises: forming a crease formation pattern on a photo-imaging cylinder (PIP) by the print unit; transferring the crease formation pattern from the PIP to the image forming blanket; and transferring the crease formation pattern from the image forming blanket to the impression paper.

15. The method according to claim 9 , wherein the pressing 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 further comprises: 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 on the impression paper to form the corresponding crease on the media during the transfer of the image to the media.

16. The image forming system according to claim 1 , wherein:
the print unit selectively forms a crease formation pattern; and
the image forming blanket is to receive and transfer the crease formation pattern to the impression paper.

17. The image forming system according to claim 1 , wherein the crease selection module further enables selection of a customizable crease formation pattern.

18. The image forming system according to claim 1 , wherein the crease formation pattern corresponds to placement of creases on the media to enable the media to be folded.

19. The image forming system according to claim 1 , further comprising the impression paper on which the crease is formed.
