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. An indicium verifier for verifying a printed indicium comprises:
an imaging module;
a verifier memory communicatively coupled to the imaging module; and
a verifier processor communicatively coupled to the verifier memory and the imaging module, wherein the verifier processor is configured to:
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;
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:
add at least one additional quiet zone area to the at least one quiet zone area;
generate at least one quiet zone grade associated with the at least one quiet zone area based at least in part on the at least one quiet zone area and the at least one additional quiet zone area; and
output verification results associated with the printed indicium based at least in part on the at least one quiet zone grade.

2. The indicium verifier of claim 1 , wherein the indicium verifier is disposed within a housing of a printing apparatus.

3. The indicium verifier of claim 1 , wherein the indicium verifier is communicatively coupled with a printing apparatus.

4. The indicium verifier 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 verifier processor is further configured to:
adjust the at least one quiet zone requirement;
generate the at least one quiet zone grade associated with the at least one quiet zone area subsequent to 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.

5. The indicium verifier of claim 4 , 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.

6. The indicium verifier of claim 5 , wherein the verifier processor is further configured to generate the at least one quiet zone grade associated with the at least one quiet zone area based at least in part on the at least one reduced quiet zone requirement.

7. The indicium verifier of claim 1 , wherein the verifier processor is further configured to:
identify the printed indicium area from the captured image;
identify an indicium area edge of the printed indicium area; and
determine a quiet zone requirement area adjacent to the indicium area edge based on a quiet zone requirement.

8. The indicium verifier of claim 7 , wherein the verifier processor is further configured to:
set the quiet zone grade portion based on the quiet zone requirement area.

9. The indicium verifier of claim 8 , wherein, in response to receiving the user input providing the overwrite quiet zone requirement indication, the verifier processor is further configured to determine whether at least one print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge.

10. The indicium verifier of claim 9 , wherein, in response to determining that the at least one print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge, the verifier processor is further configured to:
adjust the quiet zone requirement associated with a quiet zone area adjacent to the indicium area edge to a reduced quiet zone requirement; and
generate 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.

11. The indicium verifier of claim 9 , wherein, in response to determining that the at least one print media edge of the print media is not within the quiet zone requirement area adjacent to the indicium area edge, the verifier processor is further configured to:
generate 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.

12. The indicium verifier of claim 7 , wherein the verifier processor is further configured to:
determine whether at least one print media edge of the print media is within the quiet zone requirement area adjacent to the indicium area edge.

13. The indicium verifier of claim 12 , wherein, in response to determining that the at least one print media edge of the print media is within the quiet zone requirement area, the verifier processor is further configured to:
determine 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.

14. The indicium verifier of claim 12 , wherein, in response to determining that the at least one print media edge of the print media is not within the quiet zone requirement area, the verifier processor is further configured to:
determine the quiet zone requirement area as a quiet zone area associated with the indicium area edge.

15. A computer-implemented method for verifying a printed indicium comprising:
receiving, by a verifier processor of an indicium verifier, a captured image of a print media comprising the printed indicium;
extracting, by the verifier processor of the indicium verifier, 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:
adding, by the verifier processor of the indicium verifier, at least one additional quiet zone area to the at least one quiet zone area,
generating, by the verifier processor of the indicium verifier, at least one quiet zone grade associated with the at least one quiet zone area based at least in part on the at least one quiet zone area and the at least one additional quiet zone area; and
outputting, by the verifier processor of the indicium verifier, verification results associated with the printed indicium based at least in part on the at least one quiet zone grade.

16. The computer-implemented method of claim 15 , 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 further comprises:
adjusting, by the verifier processor of the indicium verifier, the at least one quiet zone requirement;
generating, by the verifier processor of the indicium verifier, the at least one quiet zone grade associated with the at least one quiet zone area subsequent to adjusting the at least one quiet zone requirement; and
outputting, by th
