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.

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

Of course. Light booths can determine the color of plastic materials, paints, and coatings used in cosmetics, leather, and even pottery. Light booths used to assess and determine precise color comparison can be used on a variety of materials.


We provide professional training to customers along with user manuals for the proper operation and maintenance of haze meters. If you have any problems during use, you can contact our experts who will quickly help you solve the problem


The haze meter test assesses the degree of light scattering that occurs when light traverses a transparent or translucent material, producing a percentage that quantifies example or cloudiness.

Ensure the source, viewing angle, and background are all neutral and standardized, and the samples are clean, and positioned for a side-by-side comparison under each light condition.


Light booths and color matching are essential for the textiles, printing, automotive, plastics, cosmetics, and coatings industries. These fields rely on tight color alignment to protect brand value and meet global quality demands for color.
