Shade Matching
Shade matching is the process of ensuring consistent color across different dye lots, rolls, or production runs using spectrophotometer readings.
Shade matching ensures color consistency across different production batches. Since dye lots vary slightly even with identical inputs, manufacturers measure each batch with a spectrophotometer that reads L*a*b* coordinates (lightness, red-green, yellow-blue).
Acceptable shade variance is measured in Delta-E (DE) — a single number representing the distance between two colors in color space. Typical tolerances: DE < 0.8 for fashion (strict), DE < 1.5 for home textiles, DE < 2.0 for technical textiles.
Shade matching workflow: (1) Measure each dye lot's shade. (2) Compare to master standard. (3) Reject, approve, or sort by shade. (4) Allocate same-shade rolls to same customer/shipment.
TextileERP integrates with spectrophotometers (Datacolor, Konica Minolta) to capture shade readings automatically, calculate DE against standards, and enforce shade-consistent order allocation.

Dye Lot
A dye lot is a batch of fabric or yarn dyed together in a single cycle. Each lot has slight shade variations that must be tracked for order consistency.
Fabric Roll
A fabric roll is the standard shipping unit for textile fabric, typically 50-150 meters. Each roll has unique attributes: dye lot, shade, GSM, width.
