CHN SPEC CMYK Spectrodensitometer (45/0, 400-700nm)

CHN SPEC CMYK Spectrodensitometer (45/0, 400-700nm)

CHN SPEC CMYK Spectrodensitometer is a specialized device used for measuring and controlling color density in the printing, packaging, labeling, and color material manufacturing industries. The device utilizes a 45°/0° measurement geometry to simulate common human viewing conditions and minimize the impact of surface gloss on measurement results.

With a spectral range of 400–700 nm, the device accurately captures color data within the visible light spectrum, supporting the evaluation of key CMYK process colors: Cyan, Magenta, Yellow, and Black. The measurement results allow technicians to quickly verify density, uniformity, and color deviation between standard samples and production runs.

The CHN SPEC CMYK is ideal for quality control (QC) labs, ink-mixing rooms, and directly on the production line. The device helps businesses standardize color inspection workflows, reduce human errors from visual inspection, minimize material waste, and maintain consistent color quality across production batches.

Key Features

• 45/0 Optical Geometry: The device uses a 45-degree ring-shaped illumination and a 0-degree viewing angle (45/0). This is the gold standard in printing color control, eliminating surface gloss to accurately reflect how the human eye perceives colors on paper and packaging.
• Full-Spectrum Spectral Analysis (400 – 700nm): Collects spectral reflectance data across the entire visible light range with a 10nm interval. This ensures significantly higher accuracy compared to traditional optical filter-based colorimeters.
• In-depth CMYK Measurement: Quickly analyzes and displays core printing industry metrics, including: Ink Density, Dot Gain, Print Contrast, Trapping, and Color Difference (dE*ab).
• Support for Multiple M-Conditions: Fully complies with M0, M1, M2, and M3 measurement standards, enabling technicians to easily manage color deviations caused by Optical Brightening Agents (OBAs) commonly found in modern printing papers.
• Smart Design & Multi-Platform Connectivity: Features an intuitive touchscreen interface combined with a convenient physical viewfinder. Supports data transmission via USB and Bluetooth to PC systems or mobile applications for report generation (ColorExpert software).
