Abstract: An inkjet printer composes a first dot group including a first base dot group from ink dots of a first ink, and a second dot group including a second base dot group and a second additional dot group from ink dots of a second ink having a weaker color developing capability than the first ink. A total proportion of the first dot group with respect to the ink dots of the first ink is set to be a first print coverage greater than or equal to 100%. A total proportion of the second dot group with respect to the ink dots of the second ink is set to be a second print coverage greater than the first print coverage. Ink dots including the second additional dot group form a first print layer, and ink dots including the first base dot group and the second base dot group form a second print layer over or under the first print layer.

Abstract: An inkjet printer ejects a first ink of a plurality of colors and a second ink. An extractor extracts an underlying layer dot group from ink dots of the first ink of each of the plurality of colors. Such underlying layer dot groups and ink dots of the second ink form a first printing layer. An image dot group including at least the ink dots, of the first ink, other than the underlying dot groups forms at least one additional printing layer. The underlying dot groups are each extracted from the ink dots of the first ink of the corresponding color based on a predetermined extraction ratio.

Abstract: A desired whole slice image corresponding to a whole object is created in a slice image creation device, in which a synthesis processor overlaps a target slice image created by a target slice image creation processor and a support slice image created by a support slice image creation processor. The synthesis processor determines a portion of the overlap region corresponding to a target printing region of the target slice image and/or a support printing region of the support slice image as a whole printing region to be printed, and determines a portion of the overlap region corresponding to both of a target non-printing region of the target slice image and a support non-printing region of the support slice image as a whole non-printing region not to be printed. The synthesis processor colors the whole printing region and the whole non-printing region with different colors to create the whole slice image.
