Quiet zone

The light zone in front of and after the barcode. The quiet zone R is necessary to set the reading equipment to the barcode. The minimum is 10 times module width X, no less than 2.5 mm. In scanner applications with a large depth of focus, the quiet zone must be larger – R = 15 times module width X, no less than 6.5 mm.
