What is Quiet zone?

For Linear symbology, the quiet zone is defined as the "no print" zone at each end of the barcode. The minimum zone needs to be 10 times the narrow bar dimension. For 2-dimensional barcodes like Data Matrix, quiet zone is required around the perimeter of the barcode. AIM specification calls for a minimum of one element width on all the four sides of the of the symbol.

What is Linear Barcode?

A single row of parallel bars and spaces of varying widths that represent data. The bars and spaces are arranged in a predetermined pattern defined by the symbology. Mil size of barcode is determined by measuring the smallest bar/spaces in the code symbology.

What is Barcode?

A barcode (also bar code) is a machine-readable representation of information (usually dark ink on a light background to create high and low reflectance which is converted to 1s and 0s). Originally, barcodes stored data in the widths and spacings of printed parallel lines, but today they also come in patterns of dots, concentric circles, and text codes hidden within images. Barcodes can be read by optical scanners called barcode readers or scanned from an image by special software. Barcodes are widely used to implement Auto ID Data Capture (AIDC) systems that improve the speed and accuracy of computer data entry. An advantage over other methods of AIDC is that it is less expensive to implement.
