4 . The image processing device according to claim 1 , further comprising:
a storage unit configured to store an amount of color material used for each of a plurality of color patches having different amounts of color material, wherein
the amount-of-representative-color-material acquisition unit acquires the amount of color material used for the color patch selected from the plurality of color patches, as the amount of representative color material.
5 . The image processing device according to claim 1 , wherein
the first t image data is data representing the plurality of colors with gradation values of a plurality of channels, and
the second image data is data representing the special color with a gradation values of one channel.
6 . The image processing device according to claim 1 , further comprising:
a display control unit configured to generate a second preview image for causing a display device to display the second image represented by the second amount-of-color-material data on a display device, and cause the display device to display the second preview image.
7 . The image processing device according to claim 1 , further comprising:
a display control unit configured to
compare an amount of color material indicated by the third amount-of-color-material data with an upper limit amount of color material,
generate the third amount-of-color-material data in which the amount of color material is converted to the upper limit amount of color material or less when the amount of color material 1 indicated by the third amount-of-color-material data exceeds the upper limit amount of color material, and
generate a third preview image for causing a display device to display an image represented by the converted third amount-of-color-material data, and cause the display device to display the third preview image.
8 . The image processing device according to claim 1 , further comprising:
a display control unit configured to
compare the amount of color material indicated by the third amount-of-color-material data with an upper limit amount of color material, and
cause a display device to display a warning when the amount of color material indicated by the third amount-of-color-material data exceeds the upper limit amount of color material.
9 . An image processing method comprising:
acquiring image data including first image data representing a first image with a plurality of colors including a color other than a special color and second image data representing a second image with the special color;
acquiring an amount of representative color material indicating an amount of a plurality of color materials used for printing a representative color included in the special color by a printing device;
converting the first image data into first amount-of-color-material data representing a color of the first image by an amount of a plurality of color materials used in the printing device, based on a color conversion profile, and converting the second image data into second amount-of-color-material data representing a color of the second image by an amount of a plurality of color materials used in the printing device, based on the amount of representative color material;
combining the first amount-of-color-material data and the second amount-of-color-material data and thus generating third amount-of-color-material data; and
