RPF SI Signature Guidelines — Do's & Don'ts
✅ Do
- Sign on plain white paper with a black or blue ink pen
- Use your usual full signature — the same one you will sign at the exam centre
- Crop tightly around the signature with a little white margin
- Scan or photograph in good light so the strokes are sharp and dark
❌ Avoid
- Signature in CAPITAL letters (rejected by most bank and SSC exams)
- Pencil, sketch pen or a digital signature drawn on the phone
- Lined or coloured paper, shadows or fingers in the frame
- Signing on the photo or a signature that is too faint to read
