PS528 Spectrodensitometer
The 3nh PS528 is a versatile spectrodensitometer specifically engineered as a quality control workhorse for ink printing, film processing, textile dyeing, and plastics electronics industries. Featuring a 45/0 circumferential uniform illumination optical system combined with high-precision nanometer spectrophotometric components, it accurately measures key printing metrics such as optical density, dot area, dot gain (TVI), and trapping efficiency, facilitating the transition from experience-based judgment to digital data management. The core advantage of the PS528 lies in its 'Multi-Purpose Versatility, Precision, and High Efficiency': equipped with 5 measuring apertures to cover full-scenario requirements from large color blocks to fine graphics, rapid 1-second measurement drastically enhances testing throughput, while 0.01D density repeatability ensures stable and dependable results. Delivering professional and accurate data for rapid on-site spot-checking, PS528 is an indispensable asset for cost reduction, efficiency enhancement, and quality optimization.
1. Professional-Grade Density Measurement Across Printing Workflows
Precisely measures critical indices including density value, density difference, dot area, dot gain, trapping, printing characteristics, print contrast, tone error and grayness, and printing plates. Supports color spaces like L*a*b and Lc*h* to satisfy comprehensive quality control needs from incoming ink verification to plate-making and pressroom management.
2. Five Interchangeable Apertures for Flexible Adaptation
Equipped with 5 measuring apertures: Φ11mm, Φ10mm, Φ6mm, Φ5mm, and Φ3mm. Users can flexibly select apertures based on sample dimensions, seamlessly handling large color patches down to small graphic elements with a single versatile device.
3. High Precision, Stability, and Reliability
16 sensor groups acquire spectral data across the 400–700 nm visible spectrum at 10 nm intervals, ensuring precise measurement across dark inks, light inks, and spot colors. Density repeatability ≤ 0.01D and colorimetric repeatability ΔE*ab ≤ 0.02 guarantee consistency, eliminating misjudgments and maintaining unified QC standards. Identify potential quality issues accurately before shipment, reduce the risk of defective products reaching customers, and minimize customer complaints
4. High-Speed Measurement Elevating Production Throughput
Single measurement speed of ~1 second, with support for 2–99 average measurement modes to eliminate sample non-uniformity errors. Onboard memory for 10,000 data records enables robust data traceability during high-volume testing.
5. Multi-Platform Software Support for Seamless Data Management
Provides multi-terminal synchronization across Android, iOS, Windows, WeChat Mini-Program, and HarmonyOS. Features automated report generation and one-click export for effortless data analysis.
