New technology to reduce ink bleeding

Gill Sans typeface keyboard should reproduce typefaces clearly. But dye-sub causes ink bleeding and it makes thin lines bold noticeably. So I developed a new technology.



Please look at the upper image. Just one pixel width of the inside of outline is gray. This image processing reduces ink bleeding. And please look at the lower image. No trace of gray pixels! Ink bleeding fills gray pixels. Thanks to that, Ink bleeding doesn't go the outside of outline.

As you see, the fidelity isn't perfect. I tried more sophisticated image processing, but failed. Such processing can make bodies thinner, but it erases serifs.

By the way, the height of the 'Shift' is about 7pt. Please compare the bellow photo with your keyboard.
