Many dyeing machine operators are also responsible for preparing dye mixes according to established formulae, and are frequently called upon to develop new color formulations and to perfectly replicate colors by sight. Most commercial dye work uses the Pantone color system, which assigns a code to each of several thousand colors. Dyeing machine operators are skilled at replicating the Pantone colors, even if they do not have access to the standard primary color dyes produced for this purpose by Pantone itself.
Because the weave and texture of fabric affects the way it holds color, a dying machine operator may also need to alter color formulas so that diverse fabrics will display precisely identical colors. Delicate fabrics require special handling — for the most fragile textiles, the dying machine operator may have to modify the washing, drying and dyeing procedure so it doesn't ruin the fabric.
