摘要： 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.

摘要： The inkjet printing apparatus is configured to be able to execute a batch adjustment process of performing a plurality of times of adjustment processes related to printing in succession based on one instruction from an outside. The conveyance control unit maintains the conveyance speed at a first speed in a period when a chart printing process is performed and a period when a chart imaging process is performed. The conveyance control unit decreases the conveyance speed from the first speed to the second speed after the end of the chart imaging process in an adjustment process except for an adjustment process that is performed last in the batch adjustment process, and increases the conveyance speed from the second speed to the first speed before the start of the chart printing process in an adjustment process that is performed next.
