Color Shade & Design Matching Inspection — by Intelgic

Zero-guesswork color assurance. Intelgic’s automated Color Shade Inspection system compares every region of your product to a master / golden template, detects shade shifts, pattern drifts, and print defects, and pins exact mismatch locations on the image—in real time.

Why it matters

Subtle color shifts and design misalignments cause costly rework, brand complaints, and line slowdowns. Human eyes fatigue; ambient light changes. Intelgic enforces objective, reproducible color and design standards on every piece, 24×7.

What the System Does

  • Reads your golden template or master design file (image or vector artwork) and defines ROIs/zones or auto-segments complex designs
  • Measures color in robust spaces (CIELAB, LCh) and evaluates ΔE (ΔE76/ΔE94/ΔE2000) against tolerance thresholds you set per zone
  • Compares design geometry (logos, motifs, stripes, halftones) for pattern, registration, and scale/rotation deviations
  • Flags any out-of-tolerance area and marks the exact pixel-level location on the review image, with defect class, zone name, ΔE value, and severity
  • Pass/Fail in under a second (typical), with alerts to stack lights, PLCs, or dashboards
  • Stores evidence (images + measurements) and issues Digital Quality Certificates (DQCs) for shipments

Key capabilities

Golden Template Matching

  • Zone-based or auto-segmented comparison
  • Separate tolerances for brand elements vs. background
  • Accept/Reject with Acceptance Matrix and AQL-style policies

Color Science You Can Trust

  • CIE-standard metrics: ΔE2000 preferred for perceptual accuracy
  • White-balance & ICC color management; device profiling
  • Optional inline spectro/sensor handshake for drift compensation
  • Lighting presets (e.g., D50 / D65) and glare-reduction optics

Design & Print Verification

  • Logo/graphic conformance (vector-to-print matching)
  • Registration, skew, warping checks; pattern repeat validation
  • Dot gain / banding / streaks / color bleeding detection

Production-Ready Engineering

  • Works on moving lines or stationary tables
  • Area-scan for discrete parts; line-scan for webs/sheets/rolls
  • Telecentric lenses for dimensional fidelity where needed
  • Triggering via encoders / photoelectric sensors; strobe lighting

Live Vision AI™ Software

  • Recipe-based setup per SKU/print lot
  • Visual heatmaps with zone overlays and ΔE per zone
  • Shift-wise analytics, Pareto by defect class, SPC trends
  • API/OPC UA/PLC integration, on-prem or edge

Typical applications

How it works (workflow)

1

Onboarding the Master

Import golden artwork (image or vector). Define ROIs or let the system auto-segment regions/patterns. Assign tolerances (e.g., ΔE00 ≤ 1.0 for logos, ≤ 2.0 background).

2

Imaging & Calibration

The system controls cameras, lenses, and lights; runs white/gray card routines and applies ICC/device profiles. Optional spectro probe for periodic verification.

3

High-Speed Comparison

Each frame is normalized for illumination and perspective; Live Vision AI computes ΔE per pixel/zone and runs design conformance checks (registration, warp, repeat).

4

Decision & Mark-up

Fails are highlighted directly on the review image with pinpoint overlays. The station outputs Pass/Fail to the line and logs full measurement data.

5

Reporting & DQC

Lot-wise and shift-wise reports, export to CSV/Excel/REST. Generate DQCs with embedded images for warranty/traceability.

Hardware options

Cameras

12–65 MP area-scan for discrete items; 8–16K line-scan for continuous webs

Lenses

Industrial prime / telecentric for critical geometry; liquid lenses for variable focus

Lighting

Dome/bar/coax; polarized to suppress glare; tunable intensity/angle

Sensing

Encoders, photoelectric triggers; optional spectro/temperature sensors

Compute

GPU controller (edge PC or industrial IPC), UPS, control panel with light controller

Mechanics

Enclosed tunnel or hood to block ambient light; stands, mounts, and guards

Integration & IT

  • PLC / MES / ERP: OPC UA/DA, Modbus/TCP, REST APIs, CSV drops
  • User Management: roles, audit logs, electronic sign-off
  • Data: image retention policies, compression, auto-purge, backups
  • Deployment: on-prem edge; optional cloud dashboard mirroring
  • Security: network segmentation, TLS where applicable, AD/SSO (optional)

Performance & tolerances

  • Color accuracy: ΔE2000 repeatability ≤ 0.5–1.0 (with proper calibration and lighting)
  • Throughput: <1 s decision for area-scan stations; line speed matched for web inspection
  • Placement accuracy: defect mark-up at pixel resolution with per-zone statistics
  • Uptime: designed for 24×7 industrial duty with health monitoring

Frequently Asked Questions

Yes—per-zone ΔE thresholds and design rules. Logos and brand colors often get tighter limits.

Enclosed optics + controlled lighting, white-balance routines, ICC/device profiles, and optional spectro checks on intervals.

Yes. We use cross-polarization, dome/coax lighting, HDR capture, and adaptive normalization to stabilize measurements.

Geometric normalization (scale/rotation/warp) aligns samples to the golden template before evaluation.

Absolutely—encoder-synchronized triggering and line-scan options keep pace with webs, sheets, or conveyors.

Get started

Bring us your golden template and two or three production samples. We’ll run a quick feasibility study, propose the optics + lighting stack, and deliver a readiness plan with ROI.
