Best Settings for Barcode Labels

Small adjustments make a big difference when you need barcodes to scan quickly and print cleanly, whether you are using Code 128, Code 39, EAN, UPC, or ITF.

Use strong contrast

Dark bars on a light background are the safest choice. Black on white is still the most dependable option for handheld scanners and mobile camera apps.

Keep the value compact

Longer values create wider barcodes. If you only need an internal SKU or location code, avoid unnecessary prefixes and extra punctuation.

Choose the right export format

• Use PNG for quick downloads and most desktop label workflows.
• Use SVG when the barcode may be resized in design software.
• Use PDF when you need a print-ready file for a document or label sheet.

Increase width for small labels

If a barcode feels cramped, increase module width before you increase complexity. Thicker bars are usually easier to print and easier to scan.

Add readable text when operators need it

Human-readable text under the bars helps when a scanner fails or when someone needs to verify the code manually.
