ABSTRACT:
The present invention provides an image-forming apparatus capable of reducing the amount of toner at a position at which the trapping is carried out. The apparatus has an image-deformation processing unit where input image data is processed to deform the image shape or the trapping or overprinting is carried out on the respective color plates. The apparatus determines whether or not the trapping should be carried out to the target pixels on the boundary between color plates in the adjacent different objects, determines the color plate having the trap color, obtains the amount of toner of the trap color, determines based on the amount of toner of the trap color and the target pixels whether or not the total amount of toner of the trap exceeds the limit value, and reduces the total amount of toner if the total amount of toner of the trap exceeds the limit value.
