X-Rite Ci™4200 / Ci™4200UV Benchtop Spectrophotometer

Overview

The X-Rite Ci™4200 and Ci™4200UV are benchtop spectrophotometers engineered for high-precision color measurement in quality control laboratories, R&D environments, and production settings where spectral fidelity, inter-instrument agreement, and regulatory traceability are critical. Based on a d/8° optical geometry with a dual-beam DRS (Dual Reference Spectral) engine, these instruments deliver simultaneous Spectral Component Included (SCI) and Spectral Component Excluded (SCE) measurements—enabling accurate assessment of both colorant-based and surface-effect-dependent samples. The Ci™4200UV variant integrates calibrated UV-LEDs to excite fluorescent whitening agents (FWAs), ensuring metrologically sound evaluation of optically brightened substrates such as paper, textiles, and plastics. All measurements conform to CIE 15:2018 and ISO 7724-1, supporting compliance with ASTM D2244, ISO 11664-4, and industry-specific color tolerance protocols (e.g., ΔE*ab, ΔE00) under standardized illuminants (D65, A, F2, etc.).

Key Features

• Simultaneous SCI/SCE acquisition in approximately 2 seconds—eliminating operator-induced variability from sequential measurement modes.
• Dual-reference spectral architecture with real-time drift compensation, enhancing long-term stability and reducing recalibration frequency.
• Integrated 60° gloss sensor co-located with the optical path, enabling concurrent color and gloss reporting without repositioning the sample.
• UV calibration routine (Ci™4200UV only) with NIST-traceable UV reference standards, essential for validating fluorescence response across instrument fleets.
• LED status panel with tactile measurement trigger and remote activation capability via external footswitch or automation interface.
• Adjustable sample clamp with preview alignment guide—ensuring repeatable positioning for flat, curved, or textured specimens.
• Flexible orientation support: vertical and horizontal mounting options accommodate integration into automated conveyors or compact lab benches.
• Full backward compatibility with X-Rite’s portable sphere-based platforms (e.g., SP62, VS450), enabling seamless data migration and cross-platform statistical process control (SPC).

Sample Compatibility & Compliance

The Ci™4200 series accommodates rigid and semi-rigid samples up to 10 mm thick and 120 mm in diameter. Its 14 mm illumination / 8 mm measurement aperture configuration meets ISO 13655 requirements for medium-area reflectance sampling. Instruments ship with factory-certified calibration tiles traceable to NIST SRM 2021 and BCRA Series II reference sets. Inter-instrument agreement is validated per ISO 13655 Annex B and reported as mean ΔE*ab ≤ 0.20 (n = 12, SCI mode, including specular component). Data integrity complies with FDA 21 CFR Part 11 when used with X-Rite’s IQ/OQ/PQ-validated software packages (e.g., Color iQC v8.0+), supporting audit-ready electronic records, user access controls, and full measurement history with timestamped metadata.

Software & Data Management

The Ci™4200 platform operates natively with X-Rite’s Color iQC and NetProfiler software suites. Color iQC provides real-time pass/fail evaluation against user-defined tolerances, statistical trend analysis (X̄/R charts), and automated report generation compliant with ISO 9001 documentation requirements. NetProfiler enables enterprise-level instrument fleet monitoring—tracking calibration status, spectral deviation, and performance drift across geographically distributed sites. Both applications support Transform functionality for converting spectral data between illuminants, observers, and color spaces (CIELAB, CMC, DIN99o, etc.), and include built-in support for custom Munsell conversion tables and pigment formulation databases. All software modules log full audit trails—including user ID, parameter changes, and measurement timestamps—in accordance with GLP and GMP documentation frameworks.

Applications

• Quality assurance of coated papers, board stocks, and packaging materials where FWA content varies batch-to-batch.
• Color matching validation in automotive interior trim, where metallic and pearlescent effects require precise SCE/SCI differentiation.
• Regulatory submission support for pharmaceutical blister packaging and medical device labeling—meeting USP , ISO 15378, and EU Annex 1 color consistency requirements.
• Textile dye lot approval in global supply chains, leveraging cross-platform data compatibility to align mill, brand, and third-party lab results.
• R&D of architectural coatings, where simultaneous gloss and color metrics inform formulation decisions related to sheen perception and hiding power.

FAQ

What distinguishes the Ci™4200UV from the standard Ci™4200?
The Ci™4200UV includes a calibrated UV-LED system and dedicated UV calibration standard, enabling quantitative measurement of fluorescence intensity and correction of its contribution to tristimulus values—critical for samples containing optical brighteners.
Can the Ci™4200 be integrated into an automated production line?
Yes—via USB HID protocol or optional Ethernet interface (with firmware v3.2+), the instrument supports PLC-triggered measurements, programmable exposure timing, and direct data streaming to MES/SCADA systems.
Is spectral data export supported in vendor-neutral formats?
Yes—measurements can be exported as CSV, XML, or CGATS.21 files, preserving full 10-nm spectral reflectance arrays and metadata required for third-party spectral analysis tools.
How often does the instrument require recalibration?
Factory calibration remains valid for 12 months under normal use; however, daily verification using supplied calibration tiles is recommended—and logged automatically by NetProfiler for audit readiness.
Does the system support multi-angle measurement?
No—the Ci™4200 is a fixed-geometry d/8° spectrophotometer. For gonioapparent materials, X-Rite recommends pairing with the MA98 multi-angle spectrophotometer within the same workflow.
