What type of image are you preparing?
├── Line art (diagram, schematic) → 1,200 DPI
├── Halftone (photo, micrograph) → 300 DPI
├── Combination (mixed text + image) → 600-900 DPI
└── Multi-panel figure
    ├── Simple panels (A, B, C) → Standard uppercase labels
    └── Sub-panels needed → Hierarchical: Ai, Aii, Bi, Bii
