What Causes Shade Variation Between Fabric Dye Lots?

Dye-lot shade variation can result from substrate differences, processing conditions, and finishing changes.

Repeat consistency depends on traceable material sources, processing records, and lot management. Keep fabric references linked to production lots and approved shade ranges; substitution or a new processing route may require renewed testing rather than automatic acceptance based on a matching description. Compare lots before allowing mixed-lot garment assembly.
