Overview
The PREMOSYS PR-0104-S is an in-line, non-contact color difference meter engineered for high-speed, repeatable spectral color measurement in industrial manufacturing environments. It operates on the CIE-compliant 45/0° optical geometry—where illumination is provided by four 45°-arranged LEDs and detection occurs at 0° normal to the sample surface—effectively excluding specular reflection and delivering robust, surface-independent color data aligned with ISO 13655:2017 (Graphic technology — Spectral measurement and colorimetric computation for graphic arts images). Designed for integration into continuous production lines, the PR-0104-S interfaces directly with the PR0128 spectrometric module via a dedicated fiber-optic coupling, enabling real-time acquisition of reflectance spectra across the visible range (400–700 nm) under stable 6500 K correlated color temperature illumination. Its architecture supports deterministic timing and synchronized triggering, making it suitable for applications requiring precise spatial registration relative to moving substrates—such as web-based printing, coating, or laminating processes.
Key Features
- True 45/0° non-contact optical configuration compliant with ISO/CIE standards for diffuse-dominant color assessment
- Integrated 6500 K LED light source with stable spectral output and minimal thermal drift over extended operation
- Fiber-coupled modular design: PR-0104-S probe connects to the PR0128 spectrometer unit via low-loss, UV-stabilized optical fiber (core diameter optimized for signal-to-noise ratio)
- High-speed acquisition capability up to 2 kHz sampling rate under configured trigger conditions—enabling sub-millimeter spatial resolution on fast-moving webs (e.g., ≥300 m/min)
- Robust industrial housing rated IP65, designed for ambient exposure in factory settings including moderate dust, humidity, and vibration
- No moving parts in the optical path—ensuring long-term calibration stability and minimal maintenance intervals
Sample Compatibility & Compliance
The PR-0104-S is validated for use with flat, semi-gloss to matte substrates commonly encountered in paper, board, flexible packaging, printed electronics, and functional coatings. It accommodates variable working distances (15–30 mm) and tolerates minor surface topography due to its collimated illumination and narrow field-of-view detection. Measurement compliance includes adherence to ASTM E308-22 (Standard Practice for Computing the Colors of Objects), ISO 11664-4:2019 (Colorimetry — Part 4: CIE 1976 L*a*b* colour space), and ISO 12233:2017 (for spatial uniformity verification of illumination). The system supports traceable calibration using NIST-traceable ceramic tile standards (e.g., BCRA Series II) and is compatible with GLP/GMP documentation workflows when paired with audit-trail-enabled software.
Software & Data Management
The PR-0104-S operates within the PREMOSYS ColorLink™ SDK and Control Suite, providing native support for Ethernet/IP and Modbus TCP protocols for PLC-level integration. Raw spectral data (31-point or higher resolution, depending on PR0128 firmware version) is exportable in CSV and XML formats compliant with ASTM E2847. Real-time ΔE00, ΔEab, and ΔECMC calculations are performed onboard or in host software, with configurable pass/fail thresholds and statistical process control (SPC) charting (X̄-R, Cpk). Full FDA 21 CFR Part 11 compliance—including electronic signatures, audit trails, role-based access control, and data integrity logging—is available through optional validation packages for regulated industries.
Applications
- Real-time color deviation monitoring during gravure, flexographic, and offset web printing
- In-process quality verification of coated paper, metallized films, and laminated packaging substrates
- Batch-to-batch consistency control in pigment dispersion and ink formulation lines
- Automated feedback control for closed-loop color correction systems (e.g., ink key adjustment or dye dosing)
- Non-destructive evaluation of weathering, oxidation, or thermal aging effects on colored polymers and automotive trim components
FAQ
What is the recommended minimum sample size for reliable measurement?
A minimum illuminated area of Ø12 mm is required; smaller features may be measured with reduced confidence due to edge diffraction and signal averaging.
Can the PR-0104-S be calibrated against customer-specific master standards?
Yes—custom reference spectra can be stored and applied as secondary calibration targets, provided they are physically stable and characterized under identical geometric and illumination conditions.
Is the system compatible with third-party MES or SCADA platforms?
Yes—via OPC UA, RESTful API, or raw socket communication; full protocol documentation and driver libraries are supplied with the system.
Does the PR-0104-S require periodic recalibration in-situ?
No scheduled recalibration is needed under normal operating conditions; however, daily verification using a certified reference tile is recommended per ISO/IEC 17025 quality procedures.
What environmental conditions limit operational reliability?
Ambient temperatures between 5–40 °C and relative humidity ≤85% non-condensing are specified; operation outside this range requires enclosure conditioning or custom thermal management.
