1. The Delta-E < 1.0 Standard

While a technician’s eye is affected by lighting and fatigue, a spectrophotometer measures the Delta-E (dE)—the mathematical distance between two colors. We maintain a strict tolerance of dE < 1.0 for all bulk sequin and embroidery dyeing lots.

2. Metamerism Management

We test every batch under four standard light sources: D65 (Daylight), TL84 (Store Light), CWF (Office Light), and U30 (Warm Light). This ensures your custom-colored sequins and threads maintain their integrity whether they are displayed under high-end retail LEDs or warm evening gala lighting.
