Overview
The X-Rite Ci7600 Benchtop Spectrophotometer is an industrial-grade, automatic spectrophotometric measurement system engineered for high-precision color specification, formulation validation, and digital color communication across global supply chains. Operating on the principle of double-beam, diffraction-grating-based spectral analysis, the Ci7600 captures full reflectance and transmittance spectra at 10-nm intervals from 360 nm to 750 nm—covering the full visible spectrum and extending into near-UV to detect fluorescence and optical brightener effects. Its dual-mode optical architecture enables simultaneous specular-included (SPIN) and specular-excluded (SPEX) measurements without mechanical reconfiguration, ensuring consistent geometry control per ISO 7724-1 and ASTM D2244. Designed for laboratory, QC, and R&D environments in textiles, packaging, plastics, coatings, and paper industries, the Ci7600 delivers metrological traceability aligned with CIE 15:2018 and supports compliance-critical workflows under FDA-regulated and GMP-aligned quality systems.
Key Features
- Simultaneous SPIN/SPEX measurement capability eliminates operator-induced geometry variability and accelerates multi-condition evaluation (e.g., gloss-sensitive surfaces or textured substrates).
- Dual UV calibration options—420 nm UV cutoff and 460 nm UV cutoff—enable precise quantification of fluorescent whitening agents (FWAs) and optical brighteners in paper, textiles, and polymer films per ISO 11475 and ASTM D6530.
- Integrated temperature and humidity sensors log ambient conditions synchronously with each spectral acquisition, supporting environmental correlation analysis and GLP-compliant data integrity per 21 CFR Part 11 audit trail requirements.
- Laser-guided transmission targeting ensures repeatable alignment across variable sample thicknesses and translucency levels, critical for film, sheet, and liquid cell applications.
- Modular aperture system: three transmission apertures (22 mm, 10 mm, 6 mm) and five reflection apertures (25 mm, 17 mm, 10 mm, 6 mm, 3.5 mm), enabling optimization for macro- and micro-area measurements—including small-batch lab samples and production-line validation targets.
- Photometric resolution of 0.01% ensures detection of subtle metamerism shifts and low-delta-E deviations, with average inter-instrument agreement (ΔE*SCI) ≤ 0.15 and repeatability (RMS ΔE*) ≤ 0.03 under controlled conditions.
Sample Compatibility & Compliance
The Ci7600 accommodates rigid, flexible, translucent, and opaque samples—including woven/nonwoven textiles, coated papers, injection-molded plastic parts, painted panels, and laminated films. Its large-sample compartment and adjustable stage support irregular geometries up to 200 × 200 mm. All optical path components are factory-calibrated against NIST-traceable standards, and instrument performance verification adheres to ASTM E2539 and ISO 13655. The system supports compliance documentation packages for ISO/IEC 17025-accredited laboratories and satisfies analytical method validation requirements outlined in USP for colorimetric identity testing. Data export formats (CxF/X, CGATS, CSV) are compatible with enterprise PLM and QMS platforms requiring structured, machine-readable color records.
Software & Data Management
Controlled via X-Rite’s cloud-enabled Color iQC software (v6.0+), the Ci7600 provides role-based user access, electronic signature support, and full 21 CFR Part 11 compliance—including audit trails, data encryption, and immutable record retention. Measurement data is timestamped, geotagged (if enabled), and annotated with environmental metadata (temperature/humidity), instrument ID, calibration history, and operator credentials. Integration with Munsell, Pantone, and proprietary brand libraries enables real-time pass/fail assessment against tolerance ellipsoids (CIEDE2000, CMC l:c). Raw spectral data (.spc) and processed colorimetric values (.csv) are exportable for statistical process control (SPC) analysis in JMP, Minitab, or custom MES interfaces.
Applications
- Color formulation validation in paint, ink, and pigment manufacturing per ASTM D313 and ISO 12048.
- Batch-to-batch consistency monitoring for automotive interior trim, medical device housings, and food-grade packaging films.
- Fluorescence profiling of recycled paperboard and FWA-dosed synthetic fibers to ensure regulatory conformity with REACH Annex XVII restrictions.
- Digital color handoff between design studios (Adobe Creative Cloud), prepress houses, and contract manufacturers using CxF³ exchange format.
- Long-term stability tracking of colorants exposed to accelerated aging (QUV, xenon arc) per ISO 4892-2.
FAQ
Does the Ci7600 support measurement of transparent or translucent materials?
Yes—the instrument includes dedicated transmission optics with laser-targeted alignment and three calibrated apertures (22 mm, 10 mm, 6 mm) optimized for films, bottles, and liquid cells.
How does the Ci7600 handle fluorescent samples?
It offers selectable UV illumination settings (420 nm and 460 nm UV cutoff filters) to isolate or suppress UV excitation, enabling accurate quantification of fluorescence intensity and chromatic shift per ISO 11475.
Is environmental condition logging mandatory during measurement?
No—it is optional but strongly recommended for GLP/GMP workflows; sensor data is embedded in every exported dataset when enabled.
Can the Ci7600 be integrated into an existing LIMS or ERP system?
Yes—via Color iQC’s RESTful API and configurable ODBC drivers, supporting automated data ingestion into LabWare LIMS, SAP QM, and Oracle Manufacturing Cloud.
What calibration standards are supplied with the instrument?
Each unit ships with a certified white ceramic tile (NIST-traceable), black trap, and air calibration reference; annual recalibration services are available through X-Rite-certified labs globally.
