When a Kannada typeface is imposed on the grid, the lines that fall on the horizontal, vertical, or at 45 degree angle, don’t cause any problem. But the lines that fall at any other angle are approximated. Rendering of the Kannada typeface on the screen is a debatable issue.
There are two ways to tackle rendering issues:
1. At the expense of compromising on the proportion of the character, we can align the strokes with the grid. Since the script that is in question is Kannada, this seems like a non-viable option.
2. The other solution is to work on the tonal illusion. By putting lighter tones of pixels around the strokes that fall inbetween two pixels, we can achieve smooth rendering. The typefaces that are designed using this rendering technique are called super-pixel type.
