CIDFont+F1

The names , F2 , F3 , and F4 are not specific font brands but rather generic placeholders created by PDF-exporting software when it fails to correctly embed the original font or its name . Key Characteristics of CID Fonts

• F1 typically has the most robust hinting because it’s the master design.
• F2–F4 may be algorithmically generated or manually tuned. High-quality families (e.g., Adobe’s Source Han) ensure all four are excellent.
• Rendering speed is identical across F1–F4 (same glyph lookup mechanism).
• File size: Embedded PDF with all four will be larger than just F1.

In some instances, these identifiers correspond to different weights of the same font (e.g., for Regular). Embedding Failures: cid font f1 f2 f3 f4 better
