Barcode Grader: Why Use And How Barcode Grading Work A barcode grader enables you to rate each barcode's quality, as opposed to a scanner, which can only tell you whether it can be read by that specific scanner.

Barcode Grader?

4. It is a device that
evaluates numerous
variables or criteria
A symbol's overall
grade serves as a
pointer to the
readability of a
symbol

7. How Does
Barcode Grading
Work?

8. The most recent ISO/IEC
standards outline the
procedures necessary for 1D &
2D barcodes
7 different characteristics of
the barcode will be measured
by a linear barcode verifier
barcodelive.org

9. Symbol contrast How monochromatic it appears to a scanner
Minimum reflectance Whether dark bars & white areas differ sufficiently
Edge contrast minimum The smallest distinction between a space and a bar
Modulation
Varying amounts of black & white contrast are present
throughout the barcode
Defects
The presence of light or dark marks in the spaces or
white marks within the bars
Decodability
How precise various bar & spacing lengths of barcode
are
Decode
Whether the data encoding, light margins on each
side, & check digit are all accurate

10. ISO/IEC grade ANSI grade
3.5 - 4.0 A
2.5 - 3.5 B
1.5 - 2.5 C
0.5 - 1.5 D
0 - 0.5 F

A barcode's total grade, which ranges from 4.0 to 0, is determined
by the results of this testing

13. What To Do If
You Receive
Failing Grades?

14. You can view a complete detailed report if the
verification software indicates that the symbol failed.
The findings of each of the 10 separate scans will be
shown, and each parameter will receive a grade.
