TILO CC120-A Standard Light Source Color Matching Cabinet

Overview

The TILO CC120-A Standard Light Source Color Matching Cabinet is an engineered optical evaluation system designed for precise, repeatable color assessment under controlled illumination conditions. It operates on the fundamental principle that human color perception is highly dependent on spectral power distribution (SPD) of incident light—variations in illuminant spectra cause metamerism and inconsistent color judgments across viewing environments. This cabinet integrates multiple standardized CIE-compliant illuminants—including D65 (simulated noon daylight, 6500 K), D50 (standard printing illuminant, 5000 K), TL84 (cool white fluorescent, commonly used in retail lighting), and CWF (cool white fluorescent, widely adopted in North American commercial settings)—to enable cross-illuminant comparison and detection of metameric failure. Its design adheres to ISO 3664:2009 and ASTM D1729–19 standards for graphic technology and color matching, ensuring metrological traceability in prepress, print production, textile dyeing, paint formulation, and plastic manufacturing workflows.

Key Features

• Multi-illuminant capability with simultaneous or independent activation of D65, D50, TL84, and CWF lamps—enabling direct side-by-side metameric evaluation
• Uniformly diffused viewing chamber with matte-black interior walls and precisely angled 45° viewing geometry to minimize specular reflection and glare
• Digital LED timer integrated into the control panel for accurate lamp aging tracking and scheduled usage logging
• High-CRI (Color Rendering Index ≥95) tri-phosphor fluorescent tubes calibrated to CIE reference spectral data at time of installation
• Ergonomic top-mounted power inlet and front-panel tactile switches with clear labeling for intuitive operation in production-floor environments
• Modular lamp access via dual quick-release white cap screws—facilitating tool-free lamp replacement without disassembly of structural components

Sample Compatibility & Compliance

The CC120-A accommodates flat, rigid, and semi-flexible specimens up to 1200 mm × 600 mm × 100 mm (L × W × H), including printed sheets, fabric swatches, coated panels, injection-molded parts, and laminated substrates. All lamp sets are certified to meet IEC 60068-2-5 (artificial weathering), ISO/IEC 17025 calibration traceability requirements when paired with optional NIST-traceable spectroradiometric verification reports. The cabinet supports GLP-compliant workflows through documented lamp usage logs and scheduled recalibration intervals aligned with ISO 9001 quality management systems. While not FDA 21 CFR Part 11–validated out-of-the-box, its operational consistency and audit-ready timer functionality make it suitable for GMP-aligned color release protocols in regulated manufacturing environments.

Software & Data Management

The CC120-A is a hardware-only instrument with no embedded firmware or network interface; however, it integrates seamlessly into digital color management ecosystems. Users may pair it with third-party spectrophotometers (e.g., X-Rite Ci7800, Konica Minolta CM-3700A) and software platforms such as X-Rite Color iMatch, Datacolor Match Pigment, or Basf ChromaCheck to correlate visual assessments with instrumental ΔE00 measurements. The built-in timer provides timestamped lamp-on duration records—critical for maintaining lamp service history per ISO 3664:2009 Clause 7.3, which mandates lamp replacement after 2000–3000 hours of cumulative operation to preserve spectral fidelity. Optional calibration certificates include spectral irradiance curves measured at 5 nm intervals across 380–780 nm.

Applications

• Prepress proof verification against contract proofs under D50/D65 illumination
• Final QC inspection of packaging films, labels, and folding cartons prior to shipment
• Textile batch-to-batch color consistency checks across global supplier networks
• Automotive interior trim color validation under both daylight (D65) and showroom lighting (TL84)
• Pharmaceutical blister foil and tablet coating evaluation where hue uniformity impacts patient compliance perception
• Academic research in color science, visual psychophysics, and lighting engineering requiring stable, reproducible illuminants

FAQ

What is the recommended lamp replacement interval?
Per ISO 3664:2009, fluorescent lamps should be replaced after 2000–3000 hours of cumulative use to maintain chromaticity coordinates within ±0.002 Δuv tolerance of target CIE values.
Can the CC120-A be used for UV-fluorescent material evaluation?
No—the CC120-A does not include UV-A (365 nm) or UV-B lamp options; it is optimized exclusively for visible-spectrum illuminants defined in ISO/CIE standards.
Is the viewing geometry compliant with ISO 3664:2009?
Yes—the cabinet employs a 45°/0° viewing configuration with diffuse illumination and non-reflective matte black interior surfaces, satisfying Clause 5.2.1 for standard viewing conditions.
Does TILO provide calibration documentation with purchase?
Each unit ships with a factory-issued lamp spectral verification report; full ISO/IEC 17025 calibration services are available upon request through authorized TILO service centers.
How is thermal stability managed during extended operation?
The cabinet features passive convection cooling channels and low-thermal-drift lamp ballasts to limit temperature rise to <2°C above ambient over 4-hour continuous operation, preserving SPD stability.
