Barcode Types Explained
Linear (1D) Barcodes
Traditional barcodes that encode data in horizontal lines of varying widths. These include UPC, EAN, Code 39, and Code 128. Best for simple numeric or short alphanumeric data.
2D Barcodes
Advanced barcodes that store data in both horizontal and vertical patterns. QR codes, Data Matrix, and PDF417 can hold significantly more information including URLs, contact details, and complex data structures.
Best Practices for Barcode Creation
1. Choose the Right Format
Select a barcode type that’s industry-standard for your application. UPC for retail, Code 39 for internal use, QR codes for marketing.
2. Ensure Proper Sizing
- Minimum recommended width: 1.5 inches for retail barcodes
- Print at 300 DPI or higher for clear scanning
- Maintain adequate quiet zones (white space) around barcodes
3. Test Before Mass Production
Always test scan your barcodes with multiple scanners before printing large quantities.
4. Use High Contrast
Black barcodes on white backgrounds provide the best scanning reliability. Avoid colored backgrounds or low-contrast combinations.
5. Maintain Data Accuracy
Double-check all numbers and text before generating barcodes. Errors in barcode data can cause scanning failures and inventory problems.
