How to prepare your signature at home?
The Right Paper
Use a plain, unruled white sheet. Avoid papers with lines, dots, or grids as they interfere with automated scanners.
Black Ink Only
Most boards (TNPSC, IBPS) strictly require a black ink ballpoint pen. Blue ink can sometimes appear too faint after compression.
The Lighting
Take the photo in natural daylight. Avoid using a camera flash as it creates 'hotspots' on the paper that make the signature unreadable.
Stable Capture
Keep your hand steady when taking the photo. Even a slight blur can cause a rejection on high-precision portals.
Top Rejection Reason:
Poor Resolution
When images are compressed blindly, they become pixelated. Our tool uses 'smart-sampling' to keep the signature stroke smooth.
Why signatures are rejected?
Portals use optical character recognition (OCR) and facial/biometric matching. If your signature is too thin, blurred, or has a domestic background (like a table or bedsheet), the server may fail to isolate the signature path.
Candidate Tip
"Always crop your signature as tightly as possible. Leave only a small white margin around the pen strokes. This ensures the signature appears large enough on your Hall Ticket."
Signature FAQs
Can I use a digital signature (drawn on screen)?
No. Most government exams strictly require a scanned copy of your original physical signature on paper.
What is the best file size for a signature?
For most Tamil Nadu exams, stay between 10KB and 20KB. Our tool locks this range for you.
My background is not perfectly white. What to do?
Try to capture the photo in brighter light. If it still looks grey, our algorithm will attempt to clean the background during compression.
Can I use a gel pen?
It's better to avoid gel pens as they might bleed through the paper. Use a standard black ballpoint pen for the sharpest lines.
