ABSTRACT:
A method of adjusting process black and a driver thereof. The method includes converting a part of process black data into mono black data. Accordingly, a user can arbitrarily adjust a ratio of process black to obtain a more natural output image and print the output image in process black and mono black, thereby reducing the consumption of ink or a colorant contained in process black.
