DTP Print & Digital Publishing Standards 2 — Questions and Answers
Question 1: Which PDF standard is required for print-ready files submitted to commercial printers?
- PDF/A-1
- PDF/X-1a (Correct answer)
- PDF/E-1
- PDF/UA-1
Correct answer: PDF/X-1a
PDF/X-1a is the industry-standard format for print-ready files, ensuring all fonts are embedded and colors are CMYK.
Question 2: What is the purpose of a 'trap' in print production?
- To prevent ink from bleeding off the page edge
- To overlap adjacent colors slightly to prevent gaps from misregistration (Correct answer)
- To lock layers so they cannot be edited
- To compress file size before sending to press
Correct answer: To overlap adjacent colors slightly to prevent gaps from misregistration
Trapping overlaps adjacent colored areas slightly so that minor misregistration on press does not create white gaps between colors.
Question 3: In digital publishing, what does EPUB stand for?
- Electronic Publishing Universal Baseline
- Enhanced Publication
- Electronic Publication (Correct answer)
- Extended Publishing Utility Bundle
Correct answer: Electronic Publication
EPUB stands for Electronic Publication and is an open standard format for reflowable digital books and documents.
Question 4: What is the standard safe-zone margin distance from the trim edge recommended to keep critical content from being cut off?
- 1/16 inch
- 1/8 inch
- 1/4 inch (Correct answer)
- 1/2 inch
Correct answer: 1/4 inch
A 1/4-inch (0.25") safety margin from the trim line is the industry standard to protect text and logos from being cut off.
Question 5: Which color rendering intent is best for reproducing photographic images in print?
- Absolute Colorimetric
- Perceptual (Correct answer)
- Saturation
- Relative Colorimetric
Correct answer: Perceptual
Perceptual rendering intent scales the entire color gamut to fit the output device, preserving visual relationships in photographs.
Question 6: What is 'choke' in the context of print trapping?
- Spreading a lighter background color inward under a darker foreground (Correct answer)
- Spreading a darker foreground color outward over a lighter background
- Reducing total ink coverage to prevent offsetting
- Applying a varnish coat over dark ink areas
Correct answer: Spreading a lighter background color inward under a darker foreground
A choke shrinks the lighter background shape inward so it slightly underlaps the darker foreground object, hiding any misregistration gap.
Question 7: Which accessibility standard governs digital document accessibility in the US federal sector?
- WCAG 2.0 Level A
- PDF/UA (ISO 14289)
- Section 508 of the Rehabilitation Act (Correct answer)
- ADA Title III

Section 508 of the Rehabilitation Act mandates that federal agencies' electronic and information technology be accessible to people with disabilities.
