Real-time multi-spectral print analysis
Real-World Use Cases
How leading brands maintain print quality excellence with Unicus Vision
Flexible Pouch Print Quality Control
A snack food manufacturer needed to detect ink smears, color shifts, and misregistration on high-speed flexible pouch lines running at 400 pouches/min.
- Multi-camera array for full surface coverage
- Spectral color analysis (Lab color space)
- AI-powered defect classification (smear vs. scratch)
- Automatic press adjustment feedback loop
Regulatory-Compliant Label Printing
A pharma company required verification of critical text (dosage, warnings) and barcodes on labels while meeting FDA 21 CFR Part 11 documentation requirements.
- OCR verification of all human-readable text
- Barcode grade validation (ISO 15416)
- Electronic audit trail with image capture
- Role-based access for quality approvals
Premium Brand Protection on Packaging
A luxury brand needed to ensure flawless print quality on foil-stamped cartons, detecting micro-defects invisible to the human eye.
- High-resolution imaging for micro-defect detection
- Gold foil coverage & consistency verification
- Embossing depth & clarity analysis
- Color consistency monitoring across batches

Why Manufacturers Choose Our Print Inspection
Detect Defects Humans Miss
Advanced imaging and AI identify micro-defects (<0.05mm) and subtle color shifts (ΔE <1.0) invisible to manual inspection.
Keep Pace with High-Speed Lines
Inspect materials moving up to 800 meters/minute with real-time processing and sub-20ms decision time.
Reduce Waste & Rework
Catch defects early in the process to minimize scrap. Typical waste reduction: 30–60% within first 6 months.
Data-Driven Process Optimization
Real-time SPC charts and defect trend analysis help identify root causes and optimize press settings proactively.
Regulatory Documentation Ready
Automated audit trails with timestamped images and electronic signatures meet FDA, EU, and ISO documentation requirements.
Fast ROI Through Quality Gains
Typical payback in 12–18 months through reduced waste, fewer customer returns, and lower manual QC labor costs.
Seamless Press & Workflow Integration
Works with your existing printing and quality management systems
