signature file size
Signature bands are quoted as 30–70 KB across current notices, with a stated minimum of 140 × 60 pixels.
How we handle it: We target 30–70 KB and never shrink below 140 × 60. Confirm against your own notification.
Requirements change with each notification cycle. Always check your own notification before you submit. We cannot guarantee acceptance.

- The file is larger than the 49 KB limit.
- The file is smaller than the 30 KB minimum, which some portals also reject.
- The file is not JPEG.
- Faint or pencil ink that does not survive scanning.
