DIS Digital Workflow & Color Management 3 — Questions and Answers
Question 1: Which white point is standard for sRGB and most web display work?
- D50
- D65 (Correct answer)
- D75
- D55
Correct answer: D65
sRGB is defined with a D65 (6500K) white point, which matches typical daylight viewing conditions for consumer monitors.
Question 2: In ICC color management, what is a 'device link' profile used for?
- Linking a camera to a printer over USB
- Converting directly between two device spaces without going through PCS (Correct answer)
- Embedding metadata links between files
- Synchronizing color settings across applications
Correct answer: Converting directly between two device spaces without going through PCS
A device link profile provides a one-step, direct conversion between two device color spaces (e.g., CMYK to CMYK) without a Profile Connection Space intermediate, preserving black channels.
Question 3: What is the primary risk of performing extensive retouching in 8-bit mode?
- Files become unreadable by print RIPs
- Banding and posterization from insufficient tonal levels (Correct answer)
- Increased noise in highlight areas
- Gamut expansion beyond sRGB
Correct answer: Banding and posterization from insufficient tonal levels
With only 256 levels per channel, aggressive curves or tonal adjustments in 8-bit can create visible banding (posterization) where smooth gradients should appear.
Question 4: A CMYK profile with a Total Ink Limit of 300% means:
- Each ink channel peaks at 75%
- The combined C+M+Y+K values cannot exceed 300% (Correct answer)
- Only 3 inks can be used simultaneously
- Black ink is capped at 30%
Correct answer: The combined C+M+Y+K values cannot exceed 300%
Total Ink Limit (TIL) specifies the maximum combined percentage of all four inks, preventing excessive ink laydown that causes paper damage or slow drying.
Question 5: Which Photoshop color setting synchronizes color management policies across all Adobe Creative Cloud applications?
- Proof Setup
- Edit > Assign Profile
- Edit > Color Settings with a CSF file via Bridge (Correct answer)
- View > Gamut Warning
Correct answer: Edit > Color Settings with a CSF file via Bridge
Saving and synchronizing a .csf (Color Settings File) through Bridge ensures all CC applications use identical color management policies and working spaces.
Question 6: What is the role of the Profile Connection Space (PCS) in ICC color management?
- It stores embedded profiles inside image files
- It serves as a common intermediate color space for converting between any two device profiles (Correct answer)
- It defines the printer's ink limit
- It caches rendered color values for speed
Correct answer: It serves as a common intermediate color space for converting between any two device profiles
The PCS (CIE XYZ or CIELAB) is the device-independent intermediate space through which all ICC conversions pass, enabling any source-to-destination profile pairing.
Question 7: When calibrating a monitor, the goal of setting a target gamma of 2.2 is to:
- Match the nonlinear response of offset printing
- Create a perceptually uniform tonal scale on the display (Correct answer)
- Maximize the monitor's color gamut
- Ensure files render identically on all operating systems
Correct answer: Create a perceptually uniform tonal scale on the display
A gamma of 2.2 encodes luminance nonlinearly in a way that matches human visual perception, distributing more tonal steps in shadows where the eye is most sensitive.
