What instrument measures the spectral reflectance of a surface across the visible spectrum wavelength by wavelength?
Answer: Spectrophotometer
A spectrophotometer measures spectral reflectance or transmittance across the visible spectrum, providing complete color data for accurate analysis.
Which color measurement instrument is most commonly used to measure ink density on offset press sheets?
Answer: Densitometer
A densitometer measures the optical density of ink on a substrate, making it the standard tool for press quality control.
The CIE L*a*b* color space is device-independent because it describes color based on what?
Answer: Human visual perception
CIE L*a*b* is based on the CIE standard observer and describes color as perceived by human vision, independent of any output device.
What does Delta E (ΔE) measure in color management?
Answer: The perceptual difference between two colors
Delta E is a numerical measure of the perceptual difference between two colors in a color space such as CIE L*a*b*.
Which measurement geometry is preferred for measuring color on glossy substrates to exclude specular reflection?
Answer: d/8° with specular excluded (SCE)
The d/8° geometry with the specular component excluded (SCE) eliminates the gloss component, giving a reading closer to how the eye sees the actual color.
What is the primary purpose of a color target such as the IT8 target in a color management workflow?
Answer: To profile input devices like scanners and cameras
The IT8 target contains known color patches used to create ICC profiles for input devices by comparing measured values to reference data.
