This presentation will review color theory, color spaces, and how ‎to use quantified data in order to ‎manage multi-component dye ‎baths using reflectance spectrophotometry.‎

Topics:

Techniques or Equipment
Advances within Existing Processes

Using multi-component dye baths can be a frustrating process ‎when not equipped with a basic understanding of color theory and ‎how different dyes are affected by various factors. These factors ‎include, but are not limited to, disproportionate consumption, ‎vulnerability towards contaminants, and decreased activity over ‎time. By utilizing reflectance spectrophotometry, the data can be ‎quantified and more easily digestible. Color spaces such as CIELAB ‎and L*C*h, which are used widely by various industries for ‎identifying target shades, can also be used for identifying ‎deviations from a standard. Armed with a better understanding of ‎how to analyze quantified data, we can more effectively and ‎efficiently make the necessary changes to an ever evolving bath to ‎increase longevity and consistency on our line.‎
