Session 10: Light Metals Processing
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.
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.
