Symbol Printing Check

This function judges a printing quality of a two-dimensional symbol captured by Code
Reader using in-line. It verifies the print quality and output the result by using
evaluation parameters of ISO15415 or AIM DPM-1-2006.
Printing quality of symbols flowing on manufacturing line is maintained at a certain
level by being checked in-line. By checking the printing quality soon after marking,
detailed time-dependent change of a marking system can be seen based on the
evaluation parameter.
Reference
 Notice that this function is for a simple check that outputs the evaluation result in
the same format with standard evaluation parameter. It cannot be used as a
proper two-dimensional symbol verifier.
 Verification results of this function may be affected by the change of imaging
conditions of Code Reader. To prevent a variance of evaluation result, use this
function under the same imaging condition (especially following conditions) as
much as possible.
- Reading distance
- Illumination condition (Light ON/OFF configuration of internal/external
illumination, illumination brightness)
- Shutter speed
- Analog gain
- Digital gain
- Black level adjustment
- Inclination of the symbol surface against Code Reader (tilt, skew, pitch)
- Amount of light around Code Reader
 Processing time becomes longer than regular symbol reading when this function is
active. Turn off when this function is not necessary.
