The use and importance of colorimeter has grown in unison with the increase of global manufacturing and processing. When plastic automotive trim produced on one continent, for example, must match a painted metal finish applied on another, an objective and precise description of color becomes an absolute necessity.
Colorimeter applications include paints, inks, plastics, textiles and apparel, food and beverages, pharmaceuticals and cosmetics, displays, and other parts and products that reflect or transmit color.
A variety of tristimulus colorimeters are available today for production color sampling, inspection and color quality control. Many are portable, battery-operated devices that allow objective color measurement on the production floor or at remote locations. They feature a range of apertures and illumination/viewing geometries for specific applications, various levels of data processing capabilities and numerous accessories.
Colorimeters in microscopelike configurations are used for accurate measurements of small objects such as pills and drug reagents. Noncontact colorimeters provide online color measurement of textiles, paper and coated coils on production lines. Small palmtop instruments have even been designed for very specific applications such as contrast measurement of baked, fried and processed foods.
By closely monitoring the consistency of color in production and processing operations, business and industry have significantly reduced the cost of waste and product rejection while improving efficiency and productivity in their operations.
