Step-by-Step Guide to Prepare & Crop SSC Signature

  1. Sign on Unlined Paper: Use a dark black gel or ballpoint pen on plain white paper. Do not use ruled notebook lines.
  2. Capture in Good Lighting: Take a straight, clear photo without shadows across the signature area.
  3. Crop Tight Borders: Remove excess empty white space around the signature before resizing.
  4. Resize & Compress: Use the live tool on this page pre-configured to 140x60 px and 20 KB max limit.
  5. Verify Output: Ensure the generated file size reads between 10.0 KB and 19.9 KB before saving.

Common Rejection Reasons in SSC Applications

  • All Capital Letters: Signatures written entirely in block capital letters (e.g., "JOHN DOE") are explicitly disallowed.
  • Blue Ink or Colored Pens: SSC algorithms mandate black ink for high-contrast OCR verification.
  • Cropped / Cut Signature: If any part of the signature loop extends outside the cropped box, the upload will fail audit.
  • Blurry / Shadowed Background: Grey paper backgrounds or shadows cause rejection at document verification stage.
