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.
