Why Spectral Data Matters: More Than Just L*a*b*
Spectral data preserves how a sample interacts with each wavelength, enabling recalculation, metamerism analysis, color indices and deeper process diagnosis beyond one L*a*b* result.

Spectrophotometer Repeatability vs Inter-Instrument Agreement
Repeatability shows how closely one spectrophotometer agrees with itself. Inter-instrument agreement shows how closely it agrees with another. Learn why both matter for reliable color control.
