This parameter grade can be “A” or “F.” The reflec-

tance value of the “lightest” space in a symbol must

be equal to or greater than twice the reflec-

tance 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 val-

ue, usually printed on the back of a template or

plaque. Bar code readers are calibrated for reflec-

tance 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.

Scanner

An electronic device that converts printed infor-

mation into electrical signals.

Scan Reflectance Profile

A record (usually graphically represented) of the

reflectance measured using the reference reflectivi-

ty method as a function of distance across the en-

tire bar code symbol.

Segment

Refers to the left and right grouping of modules or

elements into segments to designate parity for

checking validity of a scan.

Self-checking
