How to Meet the SSC Guidelines Without Rejection
SSC uses automated software to scan uploaded images before admit card issuance. To guarantee acceptance:
- Photo Quality: Ensure even lighting across both sides of the face. Do not take selfies or crop from group pictures.
- Signature Clarity: Sign with a fresh black ballpoint or gel pen on unruled white printer paper. Avoid lined notebook paper.
- File Compression: Never compress down below 20 KB for the photo, or 10 KB for the signature. Portals will flag files that are undersized.
