6. Blemish (Non-ISO Parameter)
A blemish error is defined as any mark or artifact that destroys the decode on any part of the barcode
symbol.
Within the
ISO/IEC parameters
box, there is a
Blemish
measurement. Although a blemish error is not
considered to be a part of the ISO standards, it is an extremely useful tool when troubleshooting printing
problems. The Blemish parameter is not figured into the Overall grade
unless the
Allow non-ISO blemish to
affect grade
feature is checked on the
Setup Tab
screen.
A Blemish is also a measurement of bar height consistency. Be sure to position the blue box so that it
represents the actual height of the barcode image.
A blemish can only be measured where there are decodable lines above and below the offending mark.
