Color theory and color spaces (RGB, CMYK, Lab), ICC profiling (input, display, output profiles), device
calibration and linearization, spectrophotometry and color measurement (ΔE, densitometry), rendering
intents (perceptual, relative colorimetric, saturation, absolute colorimetric), G7 and gray balance, Digital
Front Ends (DFEs) and RIPs, media and substrate effects, soft proofing, metamerism, total ink limit, GCR
(Gray Component Replacement), black point compensation, workflow standardization, evaluation
tolerances, wide-format digital printing considerations, and process control.
1. A digital press operator notices that the same CMYK file prints with a greenish cast on coated paper
but neutral on uncoated paper. What is the most likely cause?
A) The RIP is set to the wrong screening type
B) The ICC output profile does not match the paper substrate
, Page 2 of 123
C) The press needs recalibration of toner density
D) The file contains RGB images
Answer: B – Each paper type has a unique white point and ink interaction; using the wrong output
profile causes color casts.
2. Which device is required to build a custom ICC profile for a digital press?
A) Densitometer
B) Colorimeter
C) Spectrophotometer
D) Gloss meter
Answer: C – A spectrophotometer measures spectral reflectance data across wavelengths, necessary for
accurate profile creation.
3. An operator prints a grayscale ramp and measures the L* values. The ramp shows visible jumps
between steps. This indicates:
A) Successful linearization
B) Banding due to poor tonal gradation
, Page 3 of 123
C) Proper gamut mapping
D) Metameric failure
Answer: B – Non-smooth tonal transitions cause banding, indicating linearization or bit-depth issues.
4. What does a ΔE value of 1.2 represent in print quality control?
A) A large, easily visible color difference
B) A barely perceptible color difference to a trained observer
C) An exact match to the target
D) A metameric failure under D50 light
Answer: B – ΔE < 1 is imperceptible; 1-2 is noticeable only upon close inspection by trained observers.
5. A digital press produces consistent color for the first 100 sheets, then gradually shifts cooler. The
most likely cause is:
A) Paper moisture variation
B) Toner density sensor drift due to heat buildup
C) Incorrect rendering intent
D) RGB to CMYK conversion error
, Page 4 of 123
Answer: B – Digital presses can experience temperature-related drift in toner application or sensors
during long runs.
6. Which rendering intent should be used to preserve brand colors exactly when converting from a wide-
gamut RGB space to a smaller CMYK gamut?
A) Perceptual
B) Saturation
C) Relative colorimetric
D) Absolute colorimetric
Answer: C – Relative colorimetric leaves in-gamut colors unchanged, mapping only out-of-gamut colors
to the nearest reproducible hue.
7. A customer complains that a printed blue appears purple under office fluorescent lights but correct
under a D50 booth. This phenomenon is called:
A) Metamerism
B) Chromatic adaptation failure
