Abstract:
An image processing apparatus has a determination unit that determines a print operation to be performed and a generation unit that generates quantized data for printing a dot by comparing a threshold value and the multi-valued data. In a case of performing a first print operation, dot arrangement of the multiple types of inks printed on the print medium by the print unit on a basis of pieces of quantized data generated by the generation unit is higher in exclusiveness and dispersibility between or among dots of the multiple types of inks and lower in an overlap rate between or among the dots of the multiple types of inks than dot arrangement of the multiple types of inks printed on the print medium by the print unit on a basis of the pieces of quantized data generated by the generation unit in the case of performing the second print operation.
