PURPOSE: A compensation system of defective inkjets and a method thereof are provided to refer to the image data of the printed image before the controller in a printer forms the printed ink image, thereby estimating the overlap between ink drops. CONSTITUTION: A compensation system of defective inkjets (208A-208D) includes operable inkjets, an inoperable inkjet (206), and a controller. The operable inkjets are configured to spray ink on each surface for accepting an image. The controller is connected so as to act on the multiple operable inkjets and an inoperable inkjet. The controller is configured to distinguish multiple pixels in the image data to be printed by the inoperable inkjets. The controller is configured to distinguish a first location in the image data for storing a compensation pixel corresponding to one of the multiple pixels to be printed by the inoperable inkjets. The first location is distinguished by referring to the predetermined sequence of the pixel locations that one of pixel to be printed by the inoperable inkjet is located. The controller is configured to distinguish the overlap parameter for the ink so as to be sprayed by the operable inkjets. |
