Traditional Bar Analysis Tolerance
On the Grading screen, the traditional bar analysis
tolerance results are shown as Average, Maximum, and
Minimum Print Growth. Print Growth results provide
information about the bars being narrow or wide.
Based on bar reflectance crossing the Global Threshold,
the results represent the total percentage width deviation
that the bars in a symbol have when compared to the
maximum traditional dimensional specifications.
The results are normalized to plus or minus 100%
tolerance with no specific dimensions. Higher density
symbols such as 80% UPC may indicate larger ranges of
deviation than low density symbols such as ITF-14 case
code.
