4-Step Code Verification Deployment
Substrate & Code Analysis
Evaluating code size, print contrast, surface reflectivity, and line speed to select correct optics and lighting angles.
Decoder Configuration
Setting focal distance, exposure thresholds, string match masks, and ISO grading thresholds in reader firmware.
Database & PLC Handshake
Establishing TCP/IP string output links to the PLC and verifying correct mismatch rejection triggering.
Line Validation
Running live trial runs with degraded or distorted test codes to ensure zero false accepts before full plant sign-off.
OCR & Barcode Verification FAQs
What is the difference between OCR and OCV?
OCR (Optical Character Recognition) reads unknown text characters from an image and outputs the string. OCV (Optical Character Verification) checks whether a known, expected text string (like an expiration date) is present, correctly formatted, and legible.
How do you read low-contrast DataMatrix codes etched on shiny metal parts?
We use specialized 30-degree or 45-degree low-angle darkfield illumination. This lights the dot-peen indents or laser etchings obliquely while casting specular glare away from the camera lens, creating high-contrast edges for flawless decoding.
