What is the L* value for a perfect white in CIE L*a*b* color space?
Answer: 100
In CIE L*a*b*, L*=100 represents a perfect diffuse white reflector, while L*=0 represents perfect black.
Which type of ICC color profile characterizes the color behavior of an output device such as a printer?
Answer: Output profile
An ICC output profile characterizes how a printer reproduces color, enabling accurate color management by mapping device values to a device-independent color space.
What physical principle does a densitometer use to calculate ink density?
Answer: Optical density via the Beer-Lambert law
Densitometers calculate optical density from the negative logarithm of the ratio of reflected to incident light, based on Beer-Lambert principles.
What is the typical wavelength range measured by a spectrophotometer to cover the full visible spectrum?
Answer: 380–730 nm
The visible spectrum spans approximately 380 nm (violet) to 730 nm (red), and spectrophotometers measure across this range to fully characterize color.
What is 'dot gain' as measured in offset printing quality control?
Answer: The physical enlargement of halftone dots as ink spreads on the substrate
Dot gain is the physical enlargement of halftone dots as ink spreads on the substrate during printing, increasing the apparent darkness of tonal areas.
Which rendering intent should be used when converting a photographic image from a wide-gamut color space to a smaller gamut for printing?
Answer: Perceptual
Perceptual rendering intent compresses the entire gamut to fit the destination space, preserving the visual relationships between colors in photographic images.
