Question

characteristics on Barcode​

Answer 1

Answer:

Quiet Zones (Light Margins)

The Quiet Zones (Light Margin) of the bar code symbol are the solid, light areas before the first bar and after the last bar. These areas are extremely important as they allow the scanner to recognise the beginning and end of the bar code symbol.

Answer 2

the colour and type of ink you choose for your bar code symbol is very important. As a scanner reads a bar code symbol using an infrared light source it sees the symbol differently to the human eye.
