What is the quiet zone?

The calm zone is at the beginning and end of each barcode that allows the scanner to read exactly the information. The calm zone in most cases may not be very large. In fact, this often may not be distinguished for an individual consumer. In the quiet zone, no signal is created by the scanning device. This area is therefore named the "quiet zone" because of this lack of production. No silent zones can cause the scanner to read the product inaccurately or not to read the barcode at all. Those who design packaging must keep in mind. Without quiet space, scanning by today's method is unlikely to be possible. The "X" dimension is the narrowest bar found in a barcode. Due to these sizes of tiny sizes, most packages do not have difficulty maintaining this space as a quiet zone.

The calm zone gives the scanner no feedback. The scan mechanism is therefore "quiet" in terms of tUto area. This way it gets a zone. In most cases, the quiet zone has no background color if it exists at all. However, some background colors do not interfere with this area and can be used if the contrast between black stripes and background color is clear.

However, just because the scanner does not provide feedback during this time does not mean that it is idle. Instead, the silent zone provides an opportunity that the scanner must adjust. Barcode scanning requires a number of very small measurements between black stripes and white spaces. Often, this is done at a very high speed, as shown in the cash register scanner in the supermarket. So the calm zone gives the scanner enough time to calibrate for this work.
