DIS Output, Archiving & File Management 2 — Questions and Answers
Question 1: Which color profile is the standard for inkjet fine-art printing to ensure the widest gamut on matte papers?
- sRGB IEC61966-2.1
- Adobe RGB (1998)
- ProPhoto RGB (Correct answer)
- CMYK US Web Coated SWOP
Correct answer: ProPhoto RGB
ProPhoto RGB encompasses the widest color gamut and is preferred for fine-art inkjet workflows to preserve maximum tonal detail before conversion.
Question 2: When creating a LUT-based soft proof in Photoshop for a specific inkjet printer/paper combination, which menu path is correct?
- Edit > Convert to Profile
- View > Proof Setup > Custom (Correct answer)
- Image > Mode > Assign Profile
- File > Print > Color Management
Correct answer: View > Proof Setup > Custom
View > Proof Setup > Custom allows selection of a device profile to simulate on-screen how the output will appear on that printer/paper.
Question 3: A client requests a file for offset lithography with a maximum total ink coverage of 280%. Which output setting controls this?
- Black point compensation
- Total ink limit (TIL) (Correct answer)
- Rendering intent
- Dot gain curve
Correct answer: Total ink limit (TIL)
Total ink limit (TIL) caps the combined CMYK percentages to prevent excessive ink on press, which causes wet ink set-off and drying issues.
Question 4: What is the primary purpose of embedding an ICC profile in a TIFF file destined for a color-managed print workflow?
- Reduce file size through lossless compression
- Describe the color meaning of pixel values for accurate reproduction (Correct answer)
- Protect the file from unauthorized editing
- Enable layer transparency in the output
Correct answer: Describe the color meaning of pixel values for accurate reproduction
An embedded ICC profile tells downstream applications how to interpret the file's color data so it can be accurately converted for output.
Question 5: Which archival storage medium is currently recommended by the Library of Congress for long-term digital preservation of photographic files?
- Blu-ray M-DISC
- Standard DVD-R
- USB flash drive
- Magnetic tape (LTO) (Correct answer)
Correct answer: Magnetic tape (LTO)
LTO magnetic tape offers the highest capacity, lowest cost per gigabyte, and a verified lifespan exceeding 30 years for institutional archiving.
Question 6: In a DAM (Digital Asset Management) system, what does the term 'derivative asset' refer to?
- The original RAW capture file
- A version created from the master, such as a web-optimized JPEG (Correct answer)
- Metadata imported from a sidecar XMP file
- A duplicate file detected by hash comparison
Correct answer: A version created from the master, such as a web-optimized JPEG
A derivative asset is any file generated from the master asset—resized exports, color-corrected versions, or format conversions—keeping the original intact.
Question 7: Which checksum algorithm is most commonly used to verify file integrity during digital archive transfers?
- CRC16
- MD5 or SHA-256 (Correct answer)
- Base64
- Huffman coding
Correct answer: MD5 or SHA-256
MD5 and SHA-256 generate a unique hash that changes if even one bit of the file is altered, confirming a transfer completed without corruption.
