Application
The Standard Depth Scales are essential for evaluating the fastness of dyeing based on color depth. These scales establish standard depths to ensure consistency when making colorfastness comparisons. Dye manufacturers’ pattern cards reference these depths in their fastness ratings. The SDC standard depths are illustrated in a series of 6 steps, ranging from 2/1 to 1/25 depth, covering 18 hues along with 2 navies and 2 blacks.
