Overview
The Labthink SPS-80T Dual-Source Color Matching Booth is an engineered optical evaluation system designed for precise color assessment, spectral comparison, and metamerism verification in industrial quality control environments. It integrates two standardized illumination sources—CIE Illuminant D65 (6500 K, high-CRI fluorescent tube) and CIE Illuminant A (2900 K, tungsten-filament lamp)—within a single vertically oriented viewing cabinet. The system operates on the principle that accurate color judgment requires controlled, spectrally defined lighting conditions replicating standardized daylight (D65) and incandescent (A) environments. Its architecture adheres to the photometric and geometric requirements of ISO 3664:2009 for graphic technology and photography, as well as CY/T 3–1991 for Chinese printing standards. The neutral gray interior (Munsell N8 matte finish) eliminates chromatic contamination, while the precisely angled reflective hood ensures uniform illuminance (>2000 lux at viewing plane) and minimal glare across the entire 1050 mm × 700 mm observation surface.
Key Features
- Dual-standard illumination: Independently switchable CIE D65 (6500 K, Ra > 90) and Illuminant A (2900 K, Ra = 100) light sources, both calibrated to spectral power distribution tolerances specified in CIE Publication 51 and ISO 3664.
- Metamerism detection capability: Enables direct side-by-side comparison under alternating D65 and A illumination to identify metameric pairs—critical for pre-production sign-off in pigment formulation, ink manufacturing, and packaging print verification.
- Uniform irradiance field: Optimized reflector geometry and lamp positioning deliver ±15% illuminance uniformity across the full viewing area, validated per ASTM D1729 Annex A2.
- Integrated usage tracking: Built-in hour-meter logs cumulative operational time for both light sources separately, supporting preventive maintenance scheduling and lamp replacement compliance.
- Ergonomic vertical configuration: 2100 mm height accommodates standing operation; tilting anti-glare hood minimizes specular reflection from glossy substrates; modular work surfaces include hanging panel rail, horizontal sample stage, and dedicated specimen storage tray.
Sample Compatibility & Compliance
The SPS-80T supports flat, rigid, and semi-flexible samples up to 1000 mm × 650 mm in dimension and 50 mm in thickness—including printed sheets, coated films, painted panels, textile swatches, plastic injection-molded parts, and automotive trim components. All optical components comply with RoHS Directive 2011/65/EU. The device meets functional and metrological requirements of ISO 3664:2009 (graphic technology), ASTM D1729 (color matching in industry), and CY/T 3–1991 (Chinese printing standard). It is suitable for laboratories operating under GLP or ISO/IEC 17025 frameworks where documented lighting validation is required. Lamp aging protocols align with CIE Technical Report 177:2006 on maintenance of color-appearance consistency.
Software & Data Management
While the SPS-80T is a hardware-only optical evaluation station without embedded software, its design enables seamless integration into enterprise-level color management workflows. It interfaces directly with industry-standard spectrophotometers (e.g., X-Rite Ci7800, Konica Minolta CM-3700A) and color data platforms such as X-Rite Color iQC, Datacolor TOOLS, or BASF ChromaSuite via standardized physical trigger signals and synchronized exposure timing. Audit trails for lamp usage hours are retained locally and exportable via manual log entry into LIMS or QMS systems. For FDA-regulated environments (e.g., pharmaceutical packaging), the unit’s mechanical interlock switches and source identification labels support 21 CFR Part 11-compliant procedural documentation when used within validated SOPs.
Applications
- Pre-press and pressroom color approval in commercial and packaging printing
- Formulation validation of automotive coatings, architectural paints, and industrial finishes
- Quality release testing of colored plastic resins and masterbatches
- Textile dye lot conformance assessment under multiple illuminants
- R&D screening for metamerism risk in cosmetic packaging, label stock, and flexible laminates
- Calibration verification of handheld and benchtop spectrophotometers using reference tiles traceable to NIST SRM 2021
FAQ
What standards does the SPS-80T comply with?
ISO 3664:2009, CIE Publication 51, ASTM D1729, ASTM E308, CY/T 3–1991, and GB/T 9761–2008.
Can the SPS-80T be used for UV-fluorescent material evaluation?
No—this model does not include UV-A (365 nm) or UV-B emission components. A dedicated UV+D65 configuration (e.g., SPS-80UV variant) is required for fluorescent whitening agent (FWA) assessment.
How often should the D65 and A lamps be replaced?
Based on 8-hour daily operation, D65 tubes require replacement every 2,000 hours; A lamps every 1,000 hours. Hour-meter logging ensures traceable lamp lifecycle management.
Is the viewing chamber accessible for calibration with a luminance meter?
Yes—the open-top design and unobstructed viewing aperture allow insertion of calibrated photometers (e.g., Konica Minolta CS-2000) for routine illuminance and uniformity verification per ISO/TR 11664-7.
Does the unit support 110 V / 60 Hz operation without modification?
Yes—dual-voltage internal power supply (220 VAC 50 Hz / 120 VAC 60 Hz) enables plug-and-play deployment in North America, EU, and APAC regions without external transformers.
