CHN SPEC DS 528 Spectrodensitometer (Ф11mm, Ф5mm, 3mm)

CHN SPEC DS 528 Spectrodensitometer (Ф11mm, Ф5mm, 3mm)

The CHN SPEC DS-528 Spectrodensitometer is a perfect solution combining a spectrophotometer and an ink densitometer. With a convenient handheld design and a standard optical structure, this device helps packaging manufacturers and printing workshops easily control critical parameters such as CMYK ink density and dot gain, thereby ensuring the final printed products achieve the highest consistency and accuracy compared to the proof.

Outstanding Features

• Specialized for printing quality control: The device uses a 45/0 optical structure (45-degree illumination angle, 0-degree reception angle), which is the international standard optical system that most accurately simulates how the human eye perceives color on a flat surface. The device fully supports ISO 13655 standard measurement conditions including M0, M1, M2, and M3.
• Flexible support for 3 measurement apertures: The distinguishing feature of the DS-528 is the integration of 3 quickly switchable aperture sizes: Φ11mm, Φ5mm, and 3mm. This flexibility allows users to measure accurately on various color control strips (color bars) of different sizes, from large color strips to halftone dots or very small details on the print.
• Diverse analysis of printing parameters: The device not only measures Lab* color values or dE*ab color deviation but also deeply analyzes printing industry technical indices such as: ink density, dot area, dot gain, print contrast, hue error, and grayness.
• High repeatability and stability: The high-quality optical sensor helps the device achieve excellent repeatability (dE*ab ≤ 0.02), ensuring results are always consistent when measuring multiple times on the same sample or cross-checking between different work shifts.
• Intuitive design, easy operation: The DS-528 features a large color touch screen and a user-friendly interface. Operators can directly read graphs, spectral reflectance data, and Pass/Fail results right on the machine’s screen.

Practical Applications

With 3 measurement apertures and superior ink density control capabilities, the CHN SPEC DS-528 is a standard tool for:

• Medium and large-scale Offset, Flexo, and gravure printing workshops.
• Manufacturing plants for paper packaging, cartons, plastic films, and labels.
• Pre-press and quality control (QC) departments, helping to compare colors between proofs and mass prints.
• Quality inspection of input raw materials for printing ink manufacturers.
