Printing Best Practices

Always perform a test scan before mass printing. Ensure you maintain adequate "Quiet Zones" (white space) around the barcode. For thermal printers, use the "Scale" setting to match your printer's DPI to avoid aliasing artifacts.

01Retail Standards (POS)

If your product is destined for supermarket shelves or retail counters, you must use a Point-of-Sale (POS) code.

EAN-13 (International)The global standard for retail products. It encodes 13 digits: the GS1 country code, manufacturer code, product code, and check digit.
UPC-A (North America)Dominant in the US and Canada. It is technically a subset of EAN-13 (starts with 0) and encodes 12 numeric digits.

02Warehouse & Logistics

Supply chain codes need to carry more data than just an ID. They often encode batch numbers, expiration dates, and quantities.

GS1-128 / EAN-128The "gold standard" for logistics cases/pallets. It uses "Application Identifiers" (AIs) to store varied data like 'Best Before' dates (AI 15) or Serial Numbers (AI 21).
ITF-14Designed for printing on corrugated cardboard (outer cases). It has thick bars and a protective frame to withstand poor print quality.

Frequently Asked Questions

Do I need to pay for these barcodes?

No. The images generated here are 100% free to use. However, if you are creating EAN-13 or UPC-A codes for retail products, you must ensure you legally own the number sequence (usually purchased from GS1) to avoid conflicts at retailers.

Why isn't my barcode scanning?

Common reasons include: printing too small (violating minimum width), low contrast (e.g., red bars or grey background), or violating the "Quiet Zone" (printing text or graphics too close to the bars).
