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 average 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
