Abstract

A method including the steps of obtaining an original image, generating a converted image by converting a gradation of a pixel of the original image into a prescribed gradations for an image forming apparatus to express, outputting a dot pattern image through a nozzle based on a predetermined dot pattern signal, generating nozzle characteristic information of the nozzle based on the dot pattern image, generating simulation information based on the converted image and the nozzle characteristic information, generating converted simulation information by converting the simulation information to the same gradation as that of the pixel of the original image, comparing the converted simulation information with the original image, and calculating an error between the original image and the converted simulation information.
