Supported Encoding Modes

Auto (Recommended)

Automatically selects the most efficient encoding mode based on your data. This is the recommended option for most users as it optimizes data capacity and code size.

ASCII

• Encodes standard ASCII characters (0-127)
• Best for: Alphanumeric data with mixed case
• Efficiency: 1 byte per character
• Use when: Data contains letters, numbers, and symbols

C40

• Optimized for uppercase letters
• Best for: Data with mostly uppercase text
• Efficiency: 3 characters in 2 bytes
• Use when: Industrial part numbers, postal codes

Text

• Optimized for lowercase letters
• Best for: Data with mostly lowercase text
• Efficiency: 3 characters in 2 bytes
• Use when: Product descriptions, general text

X12

• ANSI X12 EDI encoding
• Best for: Electronic Data Interchange (EDI)
• Efficiency: 3 characters in 2 bytes
• Use when: Specific X12 character set required

EDIFACT

• UN/EDIFACT encoding
• Best for: International EDI standards
• Efficiency: 4 characters in 3 bytes
• Use when: International trade documents

Base 256

• Binary data encoding
• Best for: Non-text data, images, encrypted data
• Efficiency: 1 byte per byte
• Use when: Encoding binary files or encrypted content

Supported Matrix Sizes

Square Sizes

• Small: 10x10, 12x12, 14x14, 16x16, 18x18, 20x20
• Medium: 22x22, 24x24, 26x26, 32x32, 36x36, 40x40

Best Practices

1. Choose the Right Size: Use "Auto" for optimal results, or manually select based on space constraints
2. Select Appropriate Encoding: Use "Auto" unless you have specific requirements
3. Test Scanning: Always test with your actual scanning equipment before production
4. Contrast Ratio: Maintain high contrast between foreground and background colors
5. Quiet Zone: Ensure adequate white space around the code for reliable scanning
6. Print Quality: Use high-resolution printing for small codes
7. Surface: Print on flat, non-reflective surfaces when possible
8. Size: Ensure the code is large enough for your scanning distance and equipment
