1. A printing device comprising:
- an image data acquiring section that acquires an image data including a first pixel and a second pixel;
a print data producing section that produces a first print data to perform printing to a first layer by using at least color materials of achromatic colors, and produces a second print data to perform printing to the second layer that is superimposed with the first layer based on the image data; and
a print control section that controls a printing section based on the first print data and the second print data;
wherein when the brightness of the first pixel is brighter than the brightness of the second pixel, the print data producing section produces the first print data so that the brightness of the first layer corresponding to the first pixel becomes brighter than the brightness of the first layer corresponding to the second pixel.

Abstract
A basic color to be printed in achromatic colors (a layer superimposed with another layer) is changed in response to the brightness of a pixel indicated by the original image data.

9. A method of producing a printing material in which a color material is printed to a print medium comprising:
-
an image data acquiring process that acquires an image data; a print data producing process that produces a first print data providing a brightness of a first print layer corresponding to a first pixel which is brighter than a brightness of the first print layer corresponding to a second pixel and produces a second print data to perform printing by using the color material to the second print layer that is superimposed with the first print layer, so that based on the image data, the first print data and the second print data are produced when the first print data is provided to perform printing in the first print layer by using at least color material of an achromatic color and when the brightness of the first pixel indicated by the image data is included in a first brightness region and the brightness of the second pixel is included in a second brightness region which is darker than the first brightness region; and a print control process that prints the first print layer and the second print layer by controlling a printing section based on the first print data and the second print data.

10. An image generator comprising:
-
an image data acquiring section that acquires an image data; and an image generating section that produces a first image to a first layer based on brightness of the image data and produces a second image to a second layer that is superimposed with the first layer based on the image data, wherein a pixel of the second image which is based on a pixel of the image data is superimposed with a pixel of the first image which is based on the same pixel of the image data. - View Dependent Claims (11, 12, 13)

14. A method of generating an image data comprising:
-
an image data acquiring process that acquires an image data; and an image data producing process that produces data of a first image, for a first layer, based on brightness of the image data and produces data of a second image, for a second layer that is superimposed with the first layer, based on the image data, wherein a pixel of the second image which is based on a pixel of the image data is superimposed with a pixel of the first image which is based on the same pixel of the image data. - View Dependent Claims (15, 16, 17)
