The color of powders such as limestone or raw pigment powders are often measured as an incoming QC check to ensure lot-to-lot consistency of raw materials, and to ensure color accuracy of the final product, such as cosmetic facial powder or baking powder.

 

The preferred method for measuring powders is to use a Directional  45°/0° reflectance geometry for its ability to measure color the way the human eye ‘sees’ color. This is the geometry that is recommended by HunterLab for color measurement of opaque materials that will be viewed by the customer.

Many of HunterLab’s spectrophotometers are versatile enough to accommodate most applications of color measurement. However, based on 60+ years of experience and a thorough understanding of our customers’ needs and product use, these particular instruments are most suited for this industries application.
