Frequently asked questions
Why do SSC and UPSC portals reject signatures written on ruled paper?
Some application instructions ask for a signature on plain paper, and visible ruling lines can make an image harder to inspect. Requirements vary, so compare the cleaned result with the current application notice and do not assume that removing lines guarantees acceptance.
Will removing the lines erase parts of my handwriting?
It is designed to preserve darker strokes, but no image filter can guarantee that every faint or overlapping stroke will remain unchanged. Use the original-image comparison and retake the signature on plain paper if any stroke is damaged.
Can this tool convert the signature to black ink at the same time?
The default processing darkens detected strokes and creates a white background. It is only an image-cleaning step, not proof that the result meets SSC, GDS, banking, or any other portal's requirements.
What should I do after cleaning the notebook lines?
Once the background is clean, use the Signature Resizer with the relevant starting preset, then compare the dimensions and file-size range with the active notice before submitting.
How to Fix Signatures Signed on Ruled Notebook Paper
Many application notices recommend or require a signature on plain white paper, but the exact wording differs by authority and recruitment cycle. Read the active notice before relying on a cleaned image.
A signature photographed on a notebook can contain lines, shadows, and uneven contrast. The filter can reduce some of that noise, but it cannot guarantee that a portal will accept the result.
How Our Rule-Line Filtering Engine Works
School notebook manufacturers print ruled lines using light cyan or grey inks with low color saturation. When you sign over these lines with a ballpoint or gel pen, the pen ink deposits a much denser, darker layer of pigment.
The current client-side filter uses colour and luminance thresholds to reduce light horizontal lines and darken detected strokes. Because it is an image heuristic, inspect the before-and-after result carefully.
