How is barcode mil size calculated?
When creating the barcodes, the Bar Width setting equates to the mil size. Bar Width specifies the width of the narrowest element, whether it’s a bar or space, in thousandths of an inch. So a bar width setting of 5 means the narrowest bar or space in the barcode will be 0.005″, making it a 5-mil barcode.
