Summary

This section describes the post-inspection results viewing process and steps, needed after running a Barcode inspection.

Post Inspection Results


Review and Proof the Differences

  • To navigate to a barcode, click on the barcode in the Barcodes found panel in the Inspection View. The Barcode Details panel displays its parameters and grades/values.

  • An overall (average) grade is determined for the barcode based on the values of the individual parameters. These grades appear in the Barcode Details panel.

  • Consult the Barcode Scan Grid to find parameter grades for each of the selected barcode's scan lines (instead of the average).

Note: The Barcode Scan Grid appears only when 1D (linear) barcodes are inspected; The grades can be set to appear as numbers or letters.

Letters are the default setting, while the Grade output format must be set to Numbers in the selected Barcode Inspection profile. Standard users cannot create a new profile with the changed setting. Consult our Administration Guide for more information.


Barcodes Found Panel

To navigate to a barcode, click on the barcode in the Barcodes found panel in the Inspection View.

The Barcode Details panel displays its parameters and the accompanying grades/values. The barcode itself gets highlighted in the Inspection View.


Barcode Details Panel

When inspecting UPC or EAN barcodes, the Application determines whether a decoded value matches the Human Readable Value.

A match displays in green. A non-match displays in red. The panel's upper portion list each of the selected barcode's individual parameters. The remainder of this section describes each of them in detail.

1D/Composite Barcode Parameters

2

Type

Barcode type detected

3

Grade

Overall grade for the barcode; See the table below for a list of barcode grades

4

Decodability

Ease of barcode identification; The Application assigns a grade from A-F (100-0%)

5

Magnification

Percentage (+/- 10%) that a barcode has been magnified based on a starting point of 100%; Based on width to accommodate truncated barcodes and can vary from 80% to 200% except for Interleaved 2 to 5-type codes

6

Symbol Contrast

Difference in the contrast between the darkest and the lightest parts of a barcode; The system assigns a grade from A-F (100-0%)

7

Min Edge Contrast

Minimum contrast between a space and its adjacent bars; The Application assigns a pass-or-fail grade (A or F) (100-0%)

8

Modulation

The ratio between symbol contrast and minimum edge contrast; The Application assigns a grade from A-F (100-0%)

9

Defects

Amount of discrepancies in the reflectance of a barcode; The Application assigns a grade from A to F (100-0%)

10

Decode

Determination of whether the barcode was generated correctly, with sufficient spacing between bars; The system assigns a pass-or-fail grade (A or F; 4 or 0)

11

Min Reflectance

Minimum reflectance value (darkest part of the barcode); The Application assigns a pass-or-fail grade (A or F)

12

Max Reflectance

Maximum reflectance value (the lightest part of the barcode); The Application assigns a rating from 100-0

13

BWR

A measure of the decrease in bar width needed to compensate for print gain; The Application assigns a measurement in mm

14

Decoded Value

The decoded value of the selected barcode

15

Quiet Zone

Blank margins bordering a barcode; The Application assigns a pass-or-fail grade (A or F; Left% and Right %)

16

Data Structure

Type of information that is embedded in the barcode; The Application analyzes applicable barcodes as either having valid (A) or invalid (F) data structures (GS1 data matrix and QR codes only)

17

Narrow Bar

Width of the narrow bars comprising the barcode in mm; Higher DPI values yield more precise results; The Application assigns a pass-or-fail grade (A or F)

18

Wide Bar

Width of the wide bars comprising the barcode in mm; Higher DPI values yield more precise results; The Application assigns a pass-or-fail grade (A or F)

19

Wide to Narrow Ratio

The ratio that determines narrow and wide bar widths (NB: WB); The Application assigns a pass-or-fail grade (A or F)

20

Gap

Amount of space between the last black bar of one character and the first of another in mm; The Application assigns a pass-or-fail grade (A or F)

The ratio between symbol contrast and minimum edge contrast; The Application assigns a grade from A-F

6

Decode

Determination of whether the barcode was generated correctly, with sufficient spacing between bars; The Application assigns a pass-or-fail grade (A or F; 4 or 0)

7

Axial Non-Uniformity

Difference in length of the two axes of the barcode; The Application assigns a grade from A-F (0-100%)

8

Grid Non-Uniformity

Vector deviation of the barcode from an ideal position; The Application assigns a grade from A-F (0-100%)

9

Fixed Pattern Damage

Damage done to the pattern; The Application assigns a grade from A-F

10

Unused Error Correction

Amount of unused error correction embedded in the barcode; The Application assigns a grade from A-F

11

Decoded Value

The decoded value of the selected barcode

12

BWR Horizontal

A measure of the decrease in horizontal bar width needed to compensate for print gain; The Application assigns a measurement in mm

13

BWR Vertical

A measure of the decrease in vertical bar width needed to compensate for print gain; The Application assigns a measurement in mm

14

Data Structure

Type of information that is embedded in the barcode; The Application analyzes applicable barcodes as either having valid ("A") or invalid ("F") data structures (GS1 data matrix and QR codes only)

15

Cell Size

Height and width of a cell comprising the data matrix (QR code); The Application assigns a measurement in mm

16
