Looking for a Custom Color Match?
Experience true batch-to-batch color consistency when using Sigma inks to perform custom color formulation, or when ordering pre-blended colors. Every lot of Sigma ink is carefully analyzed using a spectrophotometer to ensure color consistency without drift, allowing you to formulate a color recipe once and repeat with confidence.
Custom Color Matching can be performed according to:
- Pantone Matching System
- Sample color chip
- RAL Color Standard
- Federal Standard 595
- L*a*b* color values
Color matches can be provided as a blend number to order pre-blended ink, or we can provide the blend recipe for you to mix the color match in-house on demand.
