Would you kindly make it clear.

Barcode is just a machine readable unique id to identify things that
have information in computers system.
What you mean by respective Qualities.Do you mean the quality of print
out?or the quality of the represented object.

So far as the barcode reader can read the code,it would only return
the code to the processing software that can go on with its programmed
task.so its either readable or unreadable and the scanner would
ignore.Quality of printout you would need an image processing software
and camera.If its  the quality of the represented object then its hard
to help out....you can simply imagine someone want to know the quality
of and ID holder just by looking at the ID.

If it the quality of the hardware(scanner) then its another
thing.Scanners can vary in functionalities and sensitivities if not
barcode standards.All in all they simply keyboard emulators.

But keep in mind that verification of barcodes must be done against
the previously store information .Barcodes are meant to be used with
other specialized systems with monitoring and searching capabilities
and NOT SOMETHING TO VERIFY PRODUCT QUALITY

Kindly clarify your intention.

Nicholas.
