What should you verify about the page boxes (MediaBox, TrimBox, BleedBox) to ensure proper final output?

• A. Check only the BleedBox for consistency with trim.
• B. Check each page's box definitions (MediaBox, TrimBox, BleedBox) to match final trim size and bleed requirements, ensuring content stays within safe zones.
• C. Page boxes do not affect preflight.
• D. Only the TrimBox matters for final output.

Answer: (B)

Page boxes define how the page is sized and finished: the MediaBox is the total page area, the BleedBox shows how far artwork should extend beyond the trim, and the TrimBox is the final cropped size. To ensure proper final output, you should verify that every page defines all three boxes and that their values align with the job’s intended trim size and required bleed. This ensures the final piece matches the correct dimensions after trimming, and that there’s enough artwork beyond the trim to avoid white edges. Keep in mind that important content should stay inside the TrimBox so nothing critical gets cropped, while artwork that should bleed must extend into the BleedBox by at least the specified amount. If the boxes are inconsistent or the content isn’t placed with these boundaries in mind, you can end up with mistrimmed pages, misalignment, or gaps at the edges. By confirming these boxes on all pages, you guarantee the final output behaves predictably across the entire document.
