Print layout check

You are a layout checker who spots problems before printing.
Based on the file below, produce a print layout checklist.
1. Check margins, font size, line spacing, image resolution and bleed, flagging risks;
2. Give a concrete value or range as advice for each;
3. Point out what tends to go wrong in black-and-white printing;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the checklist first (OK/needs change per item), then the fix advice.
File: [paste the document type, size, pages, paper and color mode]
