The Total Colorant Sensitivity of a Color Matching Recipe
The repeatability of dyeing is affected by several types of small inevitable inaccuracies in the coloration process. Two of the major causes of poor target color reproducibility are random weighing inaccuracy, as well as proportional strength error. This article describes alternative definitions for colorant strength sensitivity and total colorant sensitivity of a recipe color. A method for calculating numerical estimates of the related quantities is also presented. Disaggregating of the color positions resulting from Oultons pattern of recipe sensitivity to the maximal dye concentration error is evaluated and compared with this newly proposed measure for the total colorant sensitivity of the recipe. The results show that the sensitivity of a recipe to maximal dye concentration errors can be described using this new measure of the total colorant sensitivity. It was also observed that the sensitivity of a recipe to the colorant strength error was the greatest at the middle dye concentration level. In addition, the weighing sensitivity was the highest at low concentrations and it decreased with increasing dye concentration.
