Print data generation device, printing method, and program

摘要

When a skewness of brightness of a print target image is a first skewness, print data is generated such that an ink amount of a metallic ink is a first amount. When the skewness of brightness is a second skewness that is larger than the first skewness, a print data is generated such that the ink amount is a second amount that is larger than the first amount.

主权项

1. An image data generation device that generates print data for a printing apparatus capable of forming a metallic dot and a non-metallic dot, comprising:
a weighted average color separation section that sets as a target of halftone processing a value calculated using a weighted average of an ink amount obtained by performing color separation on a print target image by a first method in which the print target image which underwent color separation includes a metallic ink and an ink amount obtained by performing color separation on the print target image by a second method in which the print target image which underwent color separation does not include the metallic ink, wherein the weighted average is calculated on a basis of a skewness of brightness, when the skewness of brightness of the print target image is a first skewness, print data is generated such that the ink amount of the metallic ink is a first amount and, when the skewness of brightness is a second skewness that is larger than the first skewness, a print data is generated such that the ink amount is a second amount that is larger than the first amount, and for a human face image, regardless of the skewness of brightness, a value obtained by performing color separation by the second method is the target of the halftone processing.
