Assessing a barcode image for quality and type

< back to Staff Training 01 Course 

Goals: 

Please click the [ Mark Complete ] button at the bottom of this page when you’ve completed these goals:

  • Understand that you need to be cautious about making definitive barcode evaluations without formal testing.
  • Clarify for yourself and your staff what evaluation you will offer informally (by sight) versus formally (with the Barcode Verification Test). 
  • Be able to assess the quality of a barcode image. 
  • Be able to assess the Type of barcode image (such as EAN-13)
  • Be able to use Barcode Studio software for basic image-evaluation.

Why would you need to evaluate barcodes?

As a barcode reseller you may have clients requesting that you check their images. If you cannot provide answers they may doubt your barcode knowledge. If you can confidently provide answers they may judge you as knowledgeable and professional.

TIP:

Don’t guarantee that the barcode image is OK!

It’s normal for customers to ask your opinion on their artwork, but make it clear to them that you’re offering only an informal evaluation.

Use phrases like:

  • “I’ve taken a look at it and this image seems OK”
  • “I don’t think this image will cause a problem”
  • “If you want a guarantee, we offer a Barcode Verification Test, which comes at a price of ___ “

Watch:

   84 – Assessing a Barcode Image  
What to do when someone sends you a barcode image for assessment | Open the image, zoom in to the barcode and assess for the following…
Is it blurred? The image should be crisp with colours sharply contrasted. When a raster image like a .jpg or .png is resized it tends to blur and compromise the contrasting colours with intermediate shades/colours, which is not good for scanning. Our deliverable .svg format and the .pdf that is derived from that SVG file both scale as vector images – they don’t blur |
What is the barcode’s physical size? It should be at least 30mm wide. This is awkward to determine on a screen, so it may be necessary to print and physically measure the image | The barcode should also have white space on the left and right edges, and this is why we print a character to the far left and far right of the bar – to force white space |
IMPORTANT: Don’t guarantee that the barcode image is OK!   It’s normal for customers to ask your opinion on their artwork, but make it clear to them that you’re offering an informal evaluation, that the image seems OK and you don’t think it will be problematic, and if they want a guarantee, we offer a barcode verification test, which comes at a price of ___ |

   99 – Assessing barcodes for correctness, Analysing the barcode format from an image  
When someone asks you “Is this barcode format OK?”, you need to be able to correctly assess it – Example: EAN-13 alphanumeric = NOHow to use “Barcode Studio” demo software from Tec-it to analyse the kind of barcode from a customer-supplied image  | Website: Tec-it Barcode Studio download |
