Abstract: An operation procedure extrapolating system includes a history recording unit, a sort unit and an extrapolating unit. The history recording unit records history records of processes that at least one image processing apparatus is instructed to perform in a series of operation procedures. Each history record includes operator information, time information, content information and an object image. The sort unit sorts the history records into sets defined for individual operations, based on a comparison among the object images of the recorded history records. The extrapolating unit extrapolates operation procedures in at least one of the individual operations, based on the content information of the history records included in the set defined for the at least one of the individual operations and a sequence of the operator information of the history records included in the set defined for the at least one of the individual operations.

Abstract: Aspects of the disclosure provide a printing method that can utilize a lightly pigmented toner along with a darkly pigmented toner to improve the image quality. The method can include receiving a dataset corresponding to a printing of a printing system using a darkly pigmented toner. The printing system may have an undesirable optical density printing range for the darkly pigmented toner. Further, the method can include converting the dataset to a first dataset corresponding to a first printing of the printing system using the darkly pigmented toner, and a second dataset corresponding to a second printing of the printing system using a lightly pigmented toner. The first dataset can avoid the undesirable optical density printing range for the darkly pigmented toner, and a combination of the first printing and the second printing providing a substantially same printed optical density corresponding to the received dataset.
