Quality printing depends on precise color measurement using spectrophotometers, which provide higher measuring accuracy and a greater range of measurement values compared to devices that only show densities. Correct color settings include parameters like illuminant, observer angle, density filter, polarization filter, and white reference, which are standardized differently depending on the country or region. To match measurements between a spectrophotometer and older densitometer, the spectrophotometer must be configured with the exact same measurement settings as the densitometer.
