Abstract
A method for limiting the amount of ink discharged in a photocurable inkjet printing apparatus includes a conversion step of converting, an input grayscale value to the amount of ink; and a limit value setting step of setting, a limit value of the amount of ink discharged, for each of a secondary color not including a K color component, a tertiary color not including a K color component, and a color including a K color component. In the limit value setting step, the limit value for the tertiary color not including a K color component is set to a smaller value than the limit value for the secondary color not including a K color component, and the limit value for the color including a K color component is set to a smaller value than the limit value for the secondary color not including a K color component.
