To allow post process execution inhibited paper to be used with the post process under predetermined conditions and to be output.

An image formation system is configured to comprise: an image formation part that prints an image on paper on the basis of a job; a post process part that performs a post process to the paper on the basis of the job; and a control part that manages the job and controls printing and the post process. The control part can determine whether or not implementation inhibited paper is included in a post process execution job, and in a predetermined post process such as a bundle process and the like, when predetermined conditions such as a predetermined paper size, a predetermined paper type, the predetermined number of paper and a paper feed from a predetermined tray other than a head page and a final page are satisfied, the control part allows a job of the predetermined post process to insert implementation inhibited paper by a paper size difference with respect to a standardized size and a paper weight difference with respect to a standardized weight, a paper type difference with respect to a standardized paper type and the like into a bundle of implementable paper and allows for an output.
