Can I Print My Barcode on a Coloured Background?

Yes, It is possible to print your barcode in something other than black and white however the scanability of the barcode is depended on there being a good level of contrast between the background and the bars. So, a light yellow barcode on a white back ground would not work well whereas a dark blue on a white back ground would probably scan fine. Again it is a good idea to do a test scan before printing on all of your products.
