Anti-aliasing is a technique used by to smooth the appearance of jagged lines in graphical images. When you turn on the font-smoothing functionality in your operating system or graphic design application, for example, you’re using anti-aliasing to make the edges of the lettering and GUI elements appear smoother.
The underlying principle of anti-aliasing is the process of using shades of gray (in a black and white image) or compatible colors (in a color image) to smooth the transition from one portion of the image to the other. Thus fonts smoothed with an anti-aliasing algorithm will look slightly fuzzy under close scrutiny.
