Barcode Colour Guide
A barcode is only as good as its readability. Learn how to choose the right colours to ensure your products scan perfectly at every checkout.
The Golden Rule: Contrast is Crucial
Barcode scanners "see" the contrast between the dark bars and the light spaces. Black bars on a white background is the gold standard. The further you move away from this, the higher the risk of retail rejection.
What Works
-
Dark Bars: Use Black, Navy Blue, Dark Brown, or Dark Green.
-
Warm Backgrounds: White is optimal. You may be able to use Yellow, Orange, or Red for the background. Scanners "see" these as white.
-
Matte Finish: Always aim for a non-reflective, matte finish. Shiny surfaces confuse the scanning laser.
If you must use a dark background (like a dark blue bottle), you can print white spaces instead of black bars. This is called "Negative Printing."
What Fails
-
Red/Orange Bars: Most scanners use red light. They cannot "see" red bars against a light background.
-
Metallic & Shimmer: Gold, Silver, and metallic inks reflect light making the code unreadable.
-
Transparent Backgrounds: If the product inside (e.g., dark liquid in a bottle) shows through the barcode, it will fail to scan.
Never use gradients or patterns behind or encroaching into your barcode. The background must be one solid, uniform colour.
Don't guess—Test!
Experimenting with colour is exciting, but we always recommend testing your barcodes on a sample print before mass production.
