About This Tool
The Handwriting Ink Contrast Booster is a savior for digitizing signed agreements and historical manuscript archives.
Scans of hand-signed documents often look dull due to grey scanner glass reflection, yellow paper tint, or faded ink. Re-printing or photocopying these files results in blurry, illegible signatures. Traditional contrast tools darken the entire background, worsening the layout.
This tool utilizes **Contrast Limited Adaptive Histogram Equalization (CLAHE) and hue-based color separation**. In a secure local Canvas process, it isolates handwriting strokes (both black and blue) from background parchment, bleaches shadow wrinkles completely, and infuses faded inks with deep, saturated contrast, leaving your documents looking incredibly crisp and clean.
