Barcode FAQ

What are barcode symbologies?

Symbologies are different encoding methods for representing the data in bar/space patterns. Although most bar code scanners will read many different types of barcode symbologies, it is usually important to choose the appropriate one for the environment in which the barcode will be scanned. If you are unsure of the symbology that your data should be encoded with, then please contact us for friendly help and advice.

Where do I obtain my barcode number?

The data that is encoded in the barcode will normally be in a format that meets an international application standard. If you contact us and tell us what your barcode is for, then we will be able to inform you of the organization that you will need to contact in order to obtain your number.

Can I have my barcode produced at the size I choose?

There are standards or best practice guidelines with minimum and maximum sizes for the barcode which may limit your choice of size. It is also worth noting that depending on your printing or production method, some size may result in better quality barcodes than others. We can help to guide you to the best choice of size and will take these factors into account.

What is a light margin or quiet zone?

Most barcodes require a clear area to the left and right of the bars which must not contain text or other images. Failure to keep these areas clear is a common reason for barcodes failing to scan.

What is a digital image?

A digital image of a barcode is one that can be incorporated into artwork design in a computer application, in a similar manner to other images such as logos or photographs. Barcode images should never be manipulated, however, as a modification to the shape or size can easily result in a barcode that will not scan.

Is the printing method and substrate important?

Different printing methods and substrates will affect the original bar code image in different ways, particularly in the amount of ink spread that occurs which impacts the dimensional sizes of the printed bars. The colour of the ink used to print the bars and the colour of the substrate will also influence the ease with which the barcode can be scanned. For further advice please contact us.

How do I know my barcode will scan accurately after it has been printed?

The quality of the final printed barcode can be checked using a barcode verifier which complies with ISO/ANSI and GS1 standards. For more information on how to obtain one then please contact us.
