Traditional Analysis Tolerance Graph
-100% Tol. +100%
------RRARR+++++
This graph is similar to the ISO/ANSI Decodability
parameter grade previously described except this analy-
sis is based on the average deviations of the bars of
each character in a symbol instead of the most deviant
element in the symbol.
The width of the graph represents the total deviation
from normal reflectance that bars in a symbol can have
and still be within dimensional specifications.
The graph provides information about bars being narrow
or wide, whereas ISO/ANSI Decodability does not.
In the graph,
“A” indicates the ave
rage bar deviation of
all characters in the symbol. The
“R’s”
(if any) indicate
the range of average bar deviations.
The graph is normalized to plus or minus 100% toler-
ance with no specific dimensions. Higher density sym-
bols such as 80% UPC may indicate larger ranges of
deviation than low density symbols such as case code
