A barcode is only useful if it scans reliably off the label. Here’s how to print them properly.
Size and margins
Keep the barcode close to its nominal size and never crop the white margins on each side. Too small or too tight and scanners struggle.
When in doubt, slightly larger is safer than too small.
Format and resolution
Print from a vector file or a 300+ DPI image. Low-resolution exports produce fuzzy bars that fail intermittently.
Black bars on a white background give the best contrast.
Printer choice
Thermal label printers produce sharp, durable barcodes ideal for products and shipping. A good laser printer also works for sheet labels.
Always scan a printed sample before running the full batch.
