Features

Horizontal compression measurement, physical positioning observation window

WS 528 Color Densitometer adopts a horizontal design with a low center of gravity, which can be stable;

Measure the surface being measured. During the measurement process, you can follow the observation window;

Check the measurement position at all times to avoid measurement position errors.

Provide printing-specific measurement indicators to help users adjust colors efficiently

Color density measurement, dot area measurement, overprint rate measurement, printing contrast measurement, hue error and grayscale measurement.

Ultra-high repeatability accuracy：dE*ab≤0.02

Repeatability accuracy is the most important indicator to describe the performance of a Color Densitometer.

WS 528 Color Densitometer adopts high-precision nanometer spectroscopic devices, 

which enables the repeatability accuracy of the instrument to reach a level of dE*ab≤0.02 that is difficult to match with similar products.

WS 528 supports 3 measurement apertures

Φ11mm, Φ5mm, Φ3mm can be flexibly applied to a variety of samples of different sizes and testing conditions.

More than 30 measurement parameters and nearly 40 evaluation light sources

WS 528 Color Densitometer provide spectral reflectance, CIE-Lab, CIE-LCh,ΔE*ab, covering power, whiteness, yellowness and other 30+ measurement indicators; A, B, C...

There are nearly 40 evaluation light sources to choose from such as D50, D55, and D65, covering almost all industries.

All color measurement metrics and light source types included.

Support WeChat applet, Android, Apple, Hongmeng, mobile APP

WS 528 Color Densitometer can be connected to various mobile phones through a variety of mobile programs.

Users no longer need to transmit the color values and physical objects of samples, but can easily transmit color data through WeChat.

Users can search for the closest color among multiple sets of color cards

Users can create a personal color database and enter color card information for printing, coatings, textiles, etc. 

The created color library can be uploaded to the cloud for multi-device data sharing, making color processing more convenient.

Enterprise users can create and manage their own color card information library and color formulas in the cloud, 

and share the information library and color formulas with their own users through unique invitation codes.

Use the powerful PC-side color management system ColorExpert

WS 528 Color Densitometer comes with the Windows color management system ColorExpert, which can be connected to the WS 528 Color Densitometer via Bluetooth or USB cable. 

ColorExpert is a full-featured color management software with four major functional modules: My Color, Color Detection, Color Matching System, and Personal Center.

1. In the "My Colors" function module, users can collect or create new color libraries they need among

hundreds of color libraries shared by other users. Electricity The brain software and mobile APP can share an account, aSuitable for printing and packaging industries Solve the color quantization problem of CMYK and spot colors Provide quantitative operating guidance to printing press staffnd the color library data follows the account to achieve information synchronization between PC and mobile terminals.

2. In the "Color Detection" function module, users can calibrate, measure, and set up the

spectrophotometer through computer software. Users can use the colors in the cloud database as standard samples to measure color differences, view spectra, color difference charts, standard sample data, and export the desired data test report.

3. In the "Color Matching System" function module, it can provide users with a more convenient and

efficient color matching process. After the instrument measures the color of the sample, the system calculates the formula in the formula center and automatically corrects the color, finally achieving an accurate match. Suitable for computer automatic color matching applications in paints, coatings, printing, textiles and other fields.

4. In the "Personal Center" function module, users can edit their personal information, search or delete

connected instrument information, manage downstream users, and manage color libraries shared with downstream users.
