DTP DTP Digital Output & Web Publishing 2 — Questions and Answers
Question 1: What is the SVG file format, and why is it preferred for web icons and logos?
- A raster image format that uses indexed colors for small file sizes
- A scalable vector graphics format that renders crisply at any size without pixelation (Correct answer)
- A compressed JPEG variant optimized for transparent backgrounds
- A proprietary Adobe format for screen-based graphics only
Correct answer: A scalable vector graphics format that renders crisply at any size without pixelation
SVG (Scalable Vector Graphics) is an XML-based vector format that scales to any resolution without quality loss, making it ideal for logos, icons, and illustrations on high-density 'Retina' displays.
Question 2: What does 'accessible design' require in digital publications under US standards such as WCAG?
- All text must be displayed in a minimum of 18-point type
- Content must be perceivable, operable, understandable, and robust for users of all abilities (Correct answer)
- Digital files must be available in both PDF and ePub formats simultaneously
- All images must be replaced with text descriptions only
Correct answer: Content must be perceivable, operable, understandable, and robust for users of all abilities
WCAG (Web Content Accessibility Guidelines) specifies four principles — perceivable, operable, understandable, robust — to ensure digital content can be used by people with disabilities.
Question 3: What is the purpose of 'alt text' (alternative text) added to images in digital publishing?
- It provides a caption displayed below the image for all users
- It describes the image for screen readers and displays when the image cannot load (Correct answer)
- It stores the file name and copyright metadata for the image
- It sets the hover tooltip text shown in desktop browsers
Correct answer: It describes the image for screen readers and displays when the image cannot load
Alt text is a short textual description attached to an image that screen-reading software reads aloud for visually impaired users and that browsers display if the image file fails to load.
Question 4: In digital document publishing, what does 'hyperlink' functionality allow readers to do?
- Zoom into high-resolution versions of images within a PDF
- Click a text or image element to navigate to another page, section, or external URL (Correct answer)
- Embed a video or audio file directly inside a document page
- Annotate a document with sticky notes visible to other users
Correct answer: Click a text or image element to navigate to another page, section, or external URL
Hyperlinks in digital publications create interactive navigation, allowing readers to jump to bookmarks within the document, other documents, or external websites with a single click.
Question 5: What is 'PDF/A' format used for in digital publishing and document management?
- A PDF optimized for the smallest possible file size for email delivery
- A PDF archival standard that ensures long-term preservation and self-containment of documents (Correct answer)
- A PDF format specifically designed for interactive forms and digital signatures
- A PDF variant used exclusively for printing on large-format plotters
Correct answer: A PDF archival standard that ensures long-term preservation and self-containment of documents
PDF/A is an ISO-standardized version of PDF designed for long-term digital archiving; it requires all fonts, colors, and resources to be embedded so the document remains independently viewable for decades.
Question 6: What does 'image compression' accomplish in digital publishing, and what is the tradeoff with JPEG compression?
- It enlarges images for better clarity; JPEG loses color depth with each save
- It reduces file size to improve load speed; JPEG uses lossy compression that discards data each time the file is saved (Correct answer)
- It converts images to vector format; JPEG files become editable paths
- It embeds color profiles; JPEG strips metadata with each compression cycle
Correct answer: It reduces file size to improve load speed; JPEG uses lossy compression that discards data each time the file is saved
JPEG compression reduces file size by permanently discarding image data, so repeatedly saving a JPEG causes cumulative quality loss — a phenomenon called 'generation loss' or 'JPEG artifacts.'
