Image formation system adding pattern information to print image based on read pattern information from medium surface for determining if medium is original
View Patent ↗An image formation system includes a medium-pattern-information-read-unit that reads pattern information of a surface of a medium; a pattern-information-image-creation-unit that creates a pattern Information image based on the read pattern information; and a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium.
1. An image formation system comprising:
a processor, wherein the process functions as:
a medium-pattern-information-read-unit that reads pattern information of a surface of a medium;
a pattern-information-image-creation-unit that creates a pattern information image based on the read pattern information; and
a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium; and,
wherein the pattern information of the surface of the medium includes information indicating a random pattern unique to the medium originating in tangles of fibrous material forming the medium.
2. The image formation system of claim 1 , wherein
the pattern information image includes position information indicating a position in which the pattern information image is read from the medium.
3. The image formation system of claim 1 , further comprising the processor function as:
a pattern-information-read-area-detection-unit that detects a pattern-information-read-area from the print image, the pattern-information-read-area including an area where an image is not printed and an area where an image having so low a density that the pattern information can be read is printed,
wherein the medium-pattern-information-read-unit reads pattern information in the pattern-information-read-area detected by the pattern-information-read-area-detection-unit.
4. The image formation system of claim 3 , further comprising the processor function as:
a management-information-reception-unit that receives management information containing print image information and pattern-information-read-area-information, the print image information being information of the print image containing the pattern information image, the pattern-information-read-area-information being information concerning the pattern-information-read-area;
a management-information-storage-unit that stores the received management information;
an inquiry-information-reception-unit that receives inquiry information containing the pattern information image printed on a medium to be collated to see whether or not the medium is an original medium; and
a collation unit that collates the inquiry information with the management information stored in the management-information-storage-unit to determine whether or not the medium is the original medium.
5. The image formation system of claim 1 , wherein
the medium-pattern-information-read-unit reads the pattern information in a margin area outside an image formation area where the print image is printed in the medium.
6. The image formation system of claim 1 , wherein
the medium-pattern-information-read-unit reads the pattern information in an area other than an area where post-treatment is executed based on post-treatment information concerning the post-treatment to be executed.
7. The image formation system of claim 1 , wherein
the print unit prints the pattern information image in a color that is difficult or impossible for a human being to view.
8. The image formation system of claim 1 , wherein
the print unit prints the pattern information image at a position different from the read area of the pattern information.
9. An image formation system comprising:
a processor, wherein the processor function as:
a medium-pattern-information-read-unit that reads pattern information of a surface of a medium;
a pattern-information-image-creation-unit that creates a pattern information image based on the read pattern information;
a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium; and,
a pattern-information-read-area-detection-unit that detects a pattern-information-read-area from the print image, the pattern-information-read-area including an area where an image is not printed and an area where an image having so low a density that the pattern information can be read is printed,
wherein the medium-pattern-information-read-unit reads pattern information in a plurality of areas on the surface of the medium, and
the pattern-information-image-creation-unit creates the pattern information image based on the pattern information in an area selected from the plurality of areas, the area ma matching the pattern-information-read-area detected by a pattern-information-read-area-detection-unit.
10. An image formation system comprising:
a processor, wherein the processor function as:
a medium-pattern-information-read-unit that reads pattern information of a surface of a medium;
a pattern-information-image-creation-unit that creates a pattern information image based on the read pattern information; and
a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium; and,
a medium-pattern-information-reader capable of reading pattern information in a plurality of areas in a main scanning direction of the surface of the medium,
wherein the medium-pattern-information-read-unit can read the pattern information in an arbitrary area on a plane along the surface of the medium in the medium moving in a subscanning direction relative to the medium-pattern-information-reader.
11. An image formation system comprising:
a processor, wherein the processor function as:
a medium-pattern-information-read-unit that reads pattern information of a surface of a medium;
a pattern-information-image-creation-unit that creates a pattern information image based on the read pattern information; and
a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium; and,
a medium-pattern-information-reader placed at a given position in a main scanning direction of the medium,
wherein the medium-pattern-information-read-unit can read the pattern information in a plurality of areas along a subscanning direction of the surface of the medium in the medium moving in the subscanning direction relative to the medium-pattern-information-reader.
