Ink

Color Bold

📸 FOR AN EXACT SIGNATURE LIKE YOURS

Sign with a dark pen on plain white paper.
Use a clean, unlined surface, avoid ruled/notebook lines. A blank sheet or the back of a book cover works great.
Good, even lighting, no shadows or glare. Keep the paper flat and fill the frame.

✅ RECOMMENDED, cleanest result

Upload a photo of your signature, then give ChatGPT or Gemini the prompt below:

You are performing ink extraction, not redesign. Treat the uploaded image as the source of truth. Preserve the exact geometry, proportions, orientation, line overlaps, stroke endings, loops, gaps, pressure variations, and irregularities of the original drawing. Remove everything except the ink. Do not enhance, beautify, vectorize, stylize, or infer missing parts. Output a lossless transparent PNG where the only visible pixels are solid black (#000000) ink matching the original drawing exactly. The result should be visually indistinguishable from placing the original drawing on a photocopier using black ink only.
