Can the barcode be supplied in various file formats?
The best file format for a digital barcode vector graphic image is Encapsulated Postscript (EPS) because it can define bar dimensions precisely. Bitmap file formats will be less accurate, depending on the resolution with which they have been made and some bitmap formats approximate the image in what is known as lossy compressed formats. If a bitmap format has to be used for some reason then a high resolution TIFF image is probably the best choice.
