An image processing device method and system that enables overprint reproduction even for a composite output, despite its simple configuration.In a print server, when a construction command of a path is detected, if a trap width is set, object information is extracted from a drawing command and saved, and when the path is constructed, information which can specify the constructed path is extracted and saved with the object information. Moreover, when a drawing process is executed, a trapping process is executed on the path using saved object information. As a result, a corresponding object can be drawn by overprinting.
