Well, this seems certainly straight forward from an information theory angle of view: - Each pixel represents one bit. - Hence, we should try to increase information entropy. That's all there is to it? Certainly not, since we are creating something for human consumption. There are a couple of other factors: - The way the eye processes patterns: lateral inhibition [1] - The way the eye processes colours: photopic vision [2] - The way the brain interprets patterns - The way the brain can actually interpret ingoing information. I don't have an answer to all of these. But is pretty certain that maximizing entropy of a binary pattern is not equivalent to optimiziung reading speed.
