Inkhue 1.1.0

Print a color photo as a plain-looking black-and-white page. Scan it, and the color comes back.

ColorHide is now Inkhue

Same project, new name. Pages printed with ColorHide 1.0 still decode — the on-paper format did not change. If you installed ColorHide 1.0.0, please install Inkhue from this release (1.0.0 can't update itself across the rename).

What's new

• Better color: the neural refiner was retrained on 8× more photos — color error down about 7 % in typical scans and 11 % in harsh ones, with more detail, at the same speed.
• Writing on the page is fine now: pen strokes across the black frame used to stop decoding; now the color comes back, and the handwriting stays in the picture like it is on paper.
• Fill the paper (on by default): photos print as large as the paper allows at 100 % — larger prints mean sharper color. The width box shows centimetres and how many pixels the color comes back at.
• Print panel with a live preview: every printer and driver option, Save as PDF, copies, layout, paper, pages per sheet, margins, scale, two-sided, headers and footers.
• Faster neural decoding (~25 %), and more robust page detection overall.
