摘要： An image forming apparatus that performs correction to make gradation values adding both of two head areas (A+C, B+D) approximately equal. An area whose density is the lowest is set as a target density. Assuming densities for head areas A=70, B=100, C=40, D=90, head areas B and D are corrected with correction amount that ΔB become equal to ΔD (ΔB=ΔD=40) in accordance with target value (A+C=100).

摘要： An image forming apparatus performs a 1-pass recording by a single main scan with respect to a recording medium by a nozzle group including different overlapping nozzles that scan the same overlapping region on the recording medium to record dots. Alternatively, a multi-pass recording is performed by a plurality of main scans with respect to the overlapping region by the same nozzle group or by different nozzle groups. The recording in a central portion of the overlapping region is performed by placing emphasis on the succession or continuity of the dots, while the recording in boundary portions of the overlapping region is performed by placing emphasis on the scattering of the dots.

摘要： An image processing method is disclosed. A printer driver is a program for performing the method. The printer driver forms print image data that are printed by an inkjet recording apparatus capable of forming multi-level dots by ejecting droplets of recording liquid. The printer driver transforms image data of a manuscript into manuscript image data corresponding to the multi-level dots capable of being output from the inkjet recording apparatus by applying an image process such as a CMM process, a BG/UCR/γ correction process, and a gradation process to the image data of the manuscript; further, forms the print image data corresponding to the multi-level dots capable of being output from the inkjet recording apparatus by combining the manuscript image data with data corresponding to the multi-level dots of an image pattern indicating that the manuscript is prohibited from being duplicated by a manuscript and tint block pattern combining section.

摘要： An image forming method is provided for use with an ink-jet printing device which forms a dot on a recording medium by ejecting a drop of recording liquid. In the image forming method, an image in which a ground tint is embedded in one of a foreground part and a background part of an original image is formed, the ground tint indicating that copying of the original image is inhibited. A recording liquid adhesion area of the dot per unit area in the foreground part is made different from a recording liquid adhesion area of the dot per unit area in the background part.
