The rapid advances in the display and mobile communication technologies have profoundly challenged the traditional analog high-speed printing press as well as the still-evolving digital printing technology in delivering information to consumers. While the mobile technologies are very efficient to provide instantaneous feed of current affairs to consumers, printing on varieties of substrates beyond plain paper is still irreplaceable to marketing, packaging and additive manufacturing in the real world applications. When printing on nonwhite substrates such as glass and metallics, white colorant is often required along with the other primary colors to properly reproduce the intended color. In this paper, we will introduce a digital color control algorithm that enable white printing capability while satisfying the constraints of simultaneously achieving optimal image quality and minimal total cost of consumption.
