Abstract:
1. A method for a printing device, wherein the method determines the maximum amount of colorant to be deposited on a specific region of print media to form an image with a reduced quantity of visual defects, and wherein the method comprises the steps of: a. inputting a primary colorant value for a single colorant for a single color region of print media, wherein the primary colorant value indicates a percentage of a primary colorant to be applied by the printing device; b. inputting a secondary colorant value for two single colorants for a two color region of print media, wherein the combined value of the two single colorants indicates a combined percentage of two single colorants to be applied by the printing device; c. deriving one or more combined color limits, one for each of the number of colorants that can be applied to a single color region of print media according to a text ink limit algorithm; and d. applying each derived color ink limit for the image to limit the quantity of ink used by the printing device when one of the derived colorant limits is exceeded, and wherein the step of deriving of the colorant limit for each color utilizes an equation L
