Overview
The Ihara Electronic R800 Spectrophotometric Densitometer is a handheld, precision optical instrument engineered for high-accuracy colorimetric and densitometric analysis in print quality control, packaging inspection, and graphic arts production environments. Operating on the 45/0° ring illumination geometry—compliant with JIS Z8722, ISO 7724-1, and DIN 5033—this device eliminates directional gloss influence by employing circumferential LED lighting, ensuring repeatable measurements across textured, coated, or matte substrates. Its spectral response spans 400–700 nm at 10 nm intervals, enabling full CIE XYZ tristimulus calculation and subsequent derivation of CIELAB (L*a*b*), CIELCh, and CMYK density values. With a 3 mm measurement aperture and ΔE*ab repeatability ≤ 0.05 under controlled conditions, the R800 delivers metrological consistency required for ISO 12647-2 process standard conformance and G7-certified gray balance verification.
Key Features
- Compact handheld form factor with integrated rechargeable lithium-ion battery supporting >3,000 measurements per charge and rapid USB-C charging
- Dual-view optical system: simultaneous 2° and 10° standard observer modes selectable via firmware interface
- High-resolution color LCD display with intuitive icon-driven navigation and real-time spectral reflectance preview
- Onboard memory stores up to 400 sample measurements and 40 reference standards, organized by job ID, timestamp, and operator tag
- Integrated densitometry functions: CMYK solid density, dot gain (TVI), tone value increase, concentration difference (ΔD), and spot color deviation reporting
- Compliance-ready architecture: supports audit trail logging when paired with PHM-800 Color Management Software (sold separately)
Sample Compatibility & Compliance
The R800 accommodates rigid and flexible substrates including coated/uncoated paper, cardboard, film, metallic foils, and UV-cured inkjet prints. Its 3 mm aperture enables localized assessment of halftone dots, registration marks, and fine typography without spatial averaging artifacts. Instrument calibration adheres to traceable NIST-matched ceramic white calibration tile (included) and zero calibration cap. Regulatory alignment includes ASTM D2244 (color difference), ASTM E308 (CIE colorimetry), ASTM E1164 (spectral data reporting), ISO 5/4 (density scale definition), and JIS K7654 (printing ink evaluation). Data export formats (CSV, XML) support integration into enterprise QC workflows compliant with ISO 9001 and ISO/IEC 17025 documentation requirements.
Software & Data Management
The optional PHM-800 Color Management Software provides comprehensive desktop-based analysis, report generation, and statistical process control (SPC) charting. It enables full spectral data visualization, pass/fail tolerance band configuration per ISO 12647-2 target curves, and automated G7 grayscale calibration. All measurement records include embedded metadata: date/time stamp, instrument serial number, operator ID, illuminant (D50/D65), observer angle, and measurement geometry. Audit log functionality satisfies FDA 21 CFR Part 11 requirements for electronic records when configured with user authentication and digital signature modules. Raw spectral data export preserves full 400–700 nm reflectance curves at 10 nm resolution for third-party spectral modeling.
Applications
- Pressroom process control: real-time monitoring of ink density drift, dot gain variation, and CMYK balance during run-length production
- Prepress proof verification: validation of contract proofs against ISO 12647-7 targets using L*a*b* and ΔE2000 tolerancing
- Package printing QA: measurement of metallic inks, fluorescent pigments, and varnish-coated surfaces where 45/0° geometry mitigates specular interference
- Color formulation support: spectral reflectance database building for OEM brand color matching and substrate-specific ink development
- Educational labs: teaching spectral theory, CIE color space fundamentals, and ISO-compliant densitometry practices
FAQ
Does the R800 support spectral data export for third-party color prediction software?
Yes—raw 400–700 nm reflectance spectra are exportable in CSV format via USB connection, retaining native 10 nm sampling resolution.
Is the PHM-800 software validated for regulated industries?
PHM-800 can be configured with 21 CFR Part 11 compliance modules (electronic signatures, audit trails, role-based access), subject to site-specific IQ/OQ validation protocols.
Can the R800 measure fluorescent or metallic inks?
It provides reliable relative density and colorimetric data for most fluorescent and metallized inks; however, absolute spectral quantification requires UV-enhanced instrumentation per ISO 13655.
What is the calibration frequency recommendation?
Daily white calibration is recommended before first use and after environmental shifts; annual factory recalibration is advised for ISO/IEC 17025 traceability.
Does the device support custom tolerance sets for customer-specific color standards?
Yes—up to 40 user-defined reference standards with configurable ΔE*ab, ΔD, or TVI tolerance limits can be stored onboard and recalled per job.
