Best Practices for Barcodes
- Print Quality: Use SVG for printing to avoid blurry lines. Ensure the barcode is big enough to scan easily (at least 1 inch / 2.5cm wide).
- Quiet Zone: Allow blank space ("quiet zone") around your barcode for reliable scanning.
- Test Before Use: Always test your barcode with a scanner or app before large-scale printing.
- Contrast Matters: Print black bars on a white background for best results.
- Don't Distort: Don't stretch/compress the barcode image; scale proportionally.
About Barcodes
A barcode is a machine-readable code consisting of parallel lines (bars) and spaces that encode information. With a single scan, barcodes speed up checkout, inventory, shipping, and more.
The first barcode was scanned in 1974 on a pack of chewing gum! Today, barcodes are everywhere — from retail and healthcare to education and logistics.
For advanced uses, barcodes can be paired with QR codes, RFID tags, or databases to track items across global supply chains.
