A 1D or linear barcode is comprised of a set of parallel lines on a contrasting background.
For best results the parallel lines should be black on a white background with clear white space (the quiet zone) at each end of the vertical lines
Common symbologies for 1D barcodes include Code 128, Code 39, EAN and UPC.
The information that can be stored in a 1D barcode depends on the symbology.
The better the print quality and the higher the contrast, the easier the identification of the bar code.
