Abstract: A design device for designing a print includes a design section configured to design the print according to an instruction of a user, a three-dimensional display section configured to cause a three-dimensional preview of the designed print to be displayed, and an unrolled display section configured to cause an unrolled preview of the designed print to be displayed. Both the three-dimensional preview and the unrolled preview are simultaneously visibly displayed, and a result of a predetermined operation performed by a user on one of the three-dimensional preview and the unrolled preview is reflected on both the three-dimensional preview and the unrolled preview.

Abstract: A print image is acquired as first image data represented in a first color space used for forming an image on a first print medium. Second image data is acquired by performing, on the first image data, conversion into representation in a profile connection space using a first conversion table and white point conversion using the information on appearance in a redetermined observation environment, of a base color section where an image is not formed on the first print medium. The second image data is converted by using a second conversion table into converted image data represented in a second color space used for forming an image on a second print medium and an image corresponding to the print image is formed on the second print medium by using the converted image data.

Abstract: An image processing apparatus sets, when image data expressed in a first color space is converted, using a color conversion profile prepared in advance, into expression in a second color space used in rendering, whether to apply a printing profile including a parameter relating to color development at the time when an image is printed. The image processing apparatus performs color conversion according to the setting of the propriety of the printing profile, generates converted image data, performs, using the converted image data and a necessary parameter, physically-based rendering of a printed printing medium on which the image is printed, and generates a rendering image corresponding to appearance in a virtual space of the printed printing medium. The image processing apparatus displays the rendering image obtained in this way in a form in which a difference in the propriety of the printing profile can be compared.

Abstract: A printing method includes: a color space conversion step; a gradation determination step of determining whether a pixel group forms a gradation; and a gradation region ink amount calculation step of calculating an ink amount of the pixel group determined to form the gradation. The gradation region ink amount calculation step includes an array information acquisition step of acquiring whether pixel values are arranged linearly, in a planar manner, or in a polyhedron manner in a uniform color space, a grating color value calculation step of determining a grating color value which is a color value of a grating point in the array, a grating ink amount calculation step of calculating, using the determined grating color value, a grating ink amount which is an ink amount of the grating point in the array, and an interpolation calculation step of calculating an ink amount of the pixel group determined to form the gradation by interpolation using the calculated grating ink amount.
