Abstract

Example methods, systems, and apparatuses for verifying a printed indicium are provided. An example method may include receiving a captured image of a print media comprising the printed indicium; extracting a quiet zone grade portion from the captured image, where the quiet zone grade portion includes a printed indicium area of the printed indicium and at least one quiet zone area adjacent to the printed indicium area; in response to receiving a user input providing an overwrite quiet zone requirement indication and determining that the at least one quiet zone area does not satisfy at least one quiet zone requirement, causing at least one of adjusting the at least one quiet zone requirement to at least one reduced quiet zone requirement or adding at least one additional quiet zone area to the at least one quiet zone area.

First claim

The invention claimed is:

1. A computer-implemented method for verifying a printed indicium comprising:
receiving, by a processor of a printing apparatus, a captured image of a print media comprising the printed indicium;
extracting, by the processor of the printing apparatus, a quiet zone grade portion from the captured image, wherein the quiet zone grade portion comprises a printed indicium area of the printed indicium and at least one quiet zone area adjacent to the printed indicium area; and
in response to receiving a user input providing an overwrite quiet zone requirement indication and determining that the at least one quiet zone area satisfies at least one quiet zone requirement:
generating, by the processor of the printing apparatus, at least one quiet zone grade associated with the at least one quiet zone area without adjusting the at least one quiet zone requirement; and
outputting, by the processor of the printing apparatus, verification results associated with the printed indicium based at least in part on the at least one quiet zone grade.

2. The computer-implemented method of claim 1 , wherein, in response to receiving the user input providing the overwrite quiet zone requirement indication and determining that the at least one quiet zone area does not satisfy the at least one quiet zone requirement, the computer-implemented method comprises:
causing, by the processor of the printing apparatus, adjusting the at least one quiet zone requirement;
generating, by the processor of the printing apparatus, the at least one quiet zone grade associated with the at least one quiet zone area based on adjusting the at least one quiet zone requirement; and
outputting, by the processor of the printing apparatus, the verification results associated with the printed indicium based at least in part on the at least one quiet zone grade.

3. The computer-implemented method of claim 2 , wherein adjusting the at least one quiet zone requirement further comprises: adjusting the at least one quiet zone requirement to at least one reduced quiet zone requirement or adjusting the at least one quiet zone requirement by adding at least one additional quiet zone area to the at least one quiet zone area.

4. The computer-implemented method of claim 1 further comprising:
identifying the printed indicium area from the captured image;
identifying an indicium area edge of the printed indicium area; and
determining a quiet zone requirement area adjacent to the indicium area edge based on a quiet zone requirement.

5. The computer-implemented method of claim 4 further comprising:
setting the quiet zone grade portion based on the quiet zone requirement area.

6. The computer-implemented method of claim 5 further comprising:
in response to determining that the user input providing the overwrite quiet zone requirement indication is received, determining whether a print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge.

7. The computer-implemented method of claim 6 further comprising:
in response to determining that at least one print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge:
adjusting the quiet zone requirement associated with a quiet zone area adjacent to the indicium area edge to a reduced quiet zone requirement, and
generating a quiet zone grade based at least in part on the reduced quiet zone requirement;

wherein the verification results indicate that the quiet zone grade is associated with an overwritten quiet zone requirement.

8. The computer-implemented method of claim 6 further comprising:
in response to determining that at least one print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge:
adding an additional quiet zone area to a quiet zone area adjacent to the indicium area edge, and
generating a quiet zone grade based at least in part on the additional quiet zone area;

wherein the verification results indicate that the quiet zone grade is associated with an overwritten quiet zone.

9. The computer-implemented method of claim 5 further comprising:
in response to determining that a print media edge of the print media is not within the quiet zone requirement area adjacent to the indicium area edge, generating a quiet zone grade indicating that a quiet zone area associated with the indicium area edge satisfies the quiet zone requirement, wherein the verification results indicate that the quiet zone grade is not associated with an overwritten quiet zone requirement and is not associated with an overwritten quiet zone adjacent to the indicium area edge.

10. The computer-implemented method of claim 4 further comprising:
determining whether at least one print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge.

11. The computer-implemented method of claim 10 further comprising:
in response to determining that the at least one print media edge of the print media is within the quiet zone requirement area, determining an area between the indicium area edge of the printed indicium area and the at least one print media edge of the print media as a quiet zone area associated with the indicium area edge.

12. The computer-implemented method of claim 10 further comprising:
in response to determining that the at least one print media edge of the print media is not within the quiet zone requirement area, determining the quiet zone requirement area as a quiet zone area associated with the indicium area edge.

13. An apparatus for verifying a printed indicium, the apparatus comprising at least one processor and at least one non-transitory memory comprising program code, the at least one non-transitory memory and the program code configured to, with the at least one processor, cause the apparatus to at least:
receive a captured image of a print media comprising the printed indicium;
extract a quiet zone grade portion from the captured image, wherein the quiet zone grade portion comprises a printed indicium area of the printed indicium and at least one quiet zone area adjacent to the printed indicium area; and
in response to receiving a user input providing an overwrite quiet zone requirement indication and determining that the at least one quiet zone area satisfies at least one quiet zone requirement:
generate at least one quiet zone grade associated with the at least one quiet zone area without adjusting the at least one quiet zone requirement; and
output verification results associated with the printed indicium based at least in part on the at least one quiet zone grade.

14. The apparatus of claim 13 , wherein, in response to receiving the user input providing the overwrite quiet zone requirement indication and determining that the at least one quiet zone area does not satisfy the at least one quiet zone requirement, the at least one non-transitory memory and the program code are configured to, with the at least one processor, cause the apparatus to:
cause adjusting the at least one quiet zone requirement;
generate the at least one quiet zone grade associated with the at least one quiet zone area based on adjusting the at least one quiet zone requirement; and
output the verification results associated with the printed indicium based at least in part on the at least one quiet zone grade.

15. The apparatus of claim 13 , wherein adjusting the at least one quiet zone requirement further comprises: adjusting the at least one quiet zone requirement to at least
