How do you read barcode data?
To read a barcode, the user drags the tip of the barcode wand across the bars in an even motion. Dark bars absorb light and white spaces reflect it back. The photo diode measures the light intensity and generates a voltage waveform that is an exact duplicate of the black and white, bar and space pattern in the barcode.
Can barcodes be any size?
The barcodes have a nominal or 100% size which can be varied, and the size chosen will depend on the printing process and the quality of the inks and substrates being used.
What is Grade A barcode?
The results of this testing are used to give the barcode an overall grade, which runs from 4.0 down to 0. 4.0 is the best result, 1.5 is the pass grade for most barcodes, 0.5 is allowed for outer case barcodes printed onto brown corrugate, and 0 is a fail.
