Barcodes are familiar to everyone. A Barcode Label is a label that carries a barcode often including a human-readable number. This sounds obvious but it is not to be confused with a product label which contains a lot of information which may also include barcodes.
Printed barcodes are produced by the million either with static barcodes (same number) or consecutively numbered barcodes. They can be pre-printed or printed on-demand from blank labels. They are often stuck onto products independently of other labels, serving a number of purposes. An example of this is where a product is imported, and a distributor wishes to use a unique barcode to link the product with their company. Companies like TKMaxx also use this system whereby they would use a barcode label to cover up the existing barcode which has no link to them.
Direct Thermal & Thermal Transfer roll labels are used as barcode labels. Address Labels (A4 Sheets) of certain sizes are also used. Sometimes the unprinted labels are called Barcode Labels as that is what they are normally used for!
