Barcode Verification

Barcode Verification is a test that determines the quality of a printed barcode on a product’s packaging.  A barcode verifier machine is used to scan the printed barcode several times at varying angles and gives an ISO grade (4 – 0 / A – F) on a Barcode Verification Report.  The lower the resulting grade the more likely the barcode will have scanning difficulties.   Having an acceptable verification report is often a prerequisite to supplying larger retailers.  Major retailers typically require printed barcodes to have an ISO grade of 1.5 or higher.
Barcode Verification reports can also indicate what needs to be done to improve barcode quality.  Common causes for failed barcode verification include:

– Removal or reduction of the quiet zones (the white space either side of the code)
– Truncating the code e.g. significantly reducing the height of the barcode
– Incorrect colour combination (black bars on white background is ideal)
– Poor print resolution
– Excessive print bleed
– Incorrect check digit or non standard encoding e.g. an incorrect format
– Barcode is placed over a corner, obscured by shrink wrap or printed on an uneven surface rendering it unreadable

The EAN-13 and UPC-A barcode images we supply will pass a verification report given they are printed correctly (within 80% – 200% magnification) and not adversely altered at the graphic design stage.

Where to obtain a Barcode Verification Report

GS1 run verification reports regardless of where the barcode number is sourced.  Verification reports can also be sourced outside of GS1 meeting most retailer requirements.  Examples of this would be Coles, Bunnings, Dan Murphys who all stock products using re-seller codes. For more information please visit.

The barcode images we supply are guaranteed to pass a Barcode Verification report with a very high grade (commonly ISO grade 4) provided the print quality is sufficient and the images have not been negatively altered.

If you obtain a verification report from GS1 it will show N/A in the “GS1 Company Prefix” row. This simply means that you have not obtained the code directly from GS1 – as you have purchased it through Oz Barcodes.

Label Printing Options

The barcode images we supply are generally intended for inclusion on product artwork files such as Photoshop “.psd” or Adobe Illustrator “.ai” files.  However you can import the images or barcode numbers into label making templates or enter the numbers into label making software.  When printing to labels directly there are a few options as outlined below.

DIY – You can print your barcodes from your laptop, Mac or PC. If you have already printed your artwork then you can pick up label template sheets from an office supply store.   Just make sure the template can safely fit the supplied images with adequate quiet zones (white sections) on either side of the codes and be sure to use the highest resolution settings possible when printing and test scan prior to mass printing.  If size is an issue we can resize your codes to your particular specification within limits.  Using at home labels however increases the chances of fading and scratching potentially reducing the barcode’s ability to scan correctly at POS.

LABEL PRINTER + SOFTWARE – You other option would be to obtain a label printer for your business such as a Dymo that will have bundled software to enter the barcode numbers into and print. Prices for these range from $100 – $600. These are thermal transfer so the labels are more durable.  You can obtain the models below at most office supply stores or online.

LABEL PRINTING SERVICE – If you don’t have access to a higher resolution printer solution and want a completely professional job then we would suggest getting the labels professionally printed.  Our recommendation for professional barcode printing is Peacock Bros or Labelhouse (melbourne).
