DTP Print & Digital Publishing Standards 4 — Questions and Answers
Question 1: Which digital publishing format is primarily used for fixed-layout documents that must look identical across all devices?
- EPUB 3 reflowable
- MOBI
- PDF (Correct answer)
- HTML5
Correct answer: PDF
PDF preserves exact layout, fonts, and graphics regardless of device or screen size, making it the standard for fixed-layout digital documents.
Question 2: What does 'overprint' mean in a print production context?
- Printing a color on top of another color without knocking out the background (Correct answer)
- Printing beyond the bleed area
- Running the press a second time for additional coverage
- Setting ink density above 100%
Correct answer: Printing a color on top of another color without knocking out the background
Overprinting allows one ink layer to print over another without removing the underlying color, which is common for black text on colored backgrounds.
Question 3: In the context of digital magazines, what does the term 'folio' refer to?
- A large-format print sheet folded into sections
- A page number printed at the bottom or top of a page
- An interactive digital magazine file format used in Adobe DPS (Correct answer)
- A two-page spread layout template
Correct answer: An interactive digital magazine file format used in Adobe DPS
In Adobe Digital Publishing Suite (DPS) and its successors, a folio is the container file for a single digital magazine issue with interactive content.
Question 4: What is 'dot gain' and why does it matter in print production?
- The increase in ink dot size from film to press sheet, causing printed colors to appear darker than intended (Correct answer)
- The resolution gain when scanning at higher DPI settings
- Extra profit margin added to printing job quotes
- The expansion of the bleed area during press setup
Correct answer: The increase in ink dot size from film to press sheet, causing printed colors to appear darker than intended
Dot gain occurs when halftone dots spread on the substrate during printing, making midtones and shadows print darker than the digital file indicates.
Question 5: Which file format supports transparency natively and is preferred for web graphics with complex shapes?
- GIF
- JPEG
- PNG-24 (Correct answer)
- BMP
Correct answer: PNG-24
PNG-24 supports full 8-bit alpha channel transparency, making it ideal for web images with complex or smooth transparent edges.
Question 6: What is the purpose of a 'slug' area in a page layout document?
- An area outside the bleed for job information, instructions, and color bars that is trimmed away before delivery (Correct answer)
- The white space between columns of text
- The tracking adjustment applied to a line of type
- A named master page style for recurring layout elements
Correct answer: An area outside the bleed for job information, instructions, and color bars that is trimmed away before delivery
The slug is a non-printing area beyond the bleed where printers and designers place job tickets, crop marks, and color control strips.
Question 7: When preparing an EPUB 3 file for accessibility, which attribute must be added to all meaningful images?
- aria-label on the img element
- alt attribute with descriptive text (Correct answer)
- role='presentation' to mark all images
- longdesc pointing to an external description file
Correct answer: alt attribute with descriptive text
The alt attribute provides alternative text that screen readers announce to visually impaired users, and is required for all meaningful images in accessible EPUB files.
