Controlling Optical Brighteners
Companies are increasingly using optical brightening agents (OBAs) to achieve a "whiter-than-white" effect on a range of materials. Adding these optical brighteners gives products a brighter, whiter appearance and compensates for the yellowing that can happen with white products over time.
Adding OBAs obviously makes for a brighter product, but the addition of these brighteners fundamentally alters the way the color is seen, which has made it impossible to accurately measure color. Thus, using OBAs can create serious color matching challenges for any industry using them to create a brighter-than-white look for their products, including paper, textiles, plastics, paints, or cosmetics.
In this whitepaper we look at what OBAs are, how they affect the colors we see. What are the challenges working with OBAs in materials and fabrics that appear similar in production, but may look much different under varied lighting conditions, such a retail store, daylight, or household light.
