Reference Decode
Each symbology type specifies a specific decoding method to be used in determining
overall symbol grade.
This parameter grade can be “A” or “F.” (“A” is pass and “F” is fail.) If this parameter
is “F” the overall symbol grade will also be “F” regardless of any other parameter. If this
parameter is “A” the lowest of the other parameter grades determines the overall symbol
grade.
Reflectance
A measure of the amount of light reflected from an illuminated surface.
Refl(min) / Refl (max)
This parameter grade can be “A” or “F.” The reflectance value of the “lightest” space in
a symbol must be equal to or greater than twice the reflectance value of the “darkest”
bar.
Refl(max) = or > Refl(min) x 2 if “yes” “A” else “F”
Reflectance Calibration Standard
(See plaque) A standard or “known” reflectance value, usually printed on the back of a
template or plaque. Bar-code readers are calibrated for reflectance using these known values.
Required PCS
This is the minimum PCS percent required for the symbol.
Resolution
The dimension of the smallest code element that can be printed; the higher the resolution
the clearer the image.
