## Abstract

An image processing device in which a display section is caused to display a preview image for printing. The image processing device includes a processing section configured to generate the preview image obtained by converting raster image data of each of ink colors of color inks or special color inks into an RGB bitmap format, and a display controller configured to cause the display section to display the generated preview.

## Claims

### Claim 1

An image processing device in which a display section is caused to display a preview image for printing, the image processing device comprising:
a processing section configured to generate the preview image obtained by converting raster image data of each of ink colors of color inks or special color inks into an RGB bitmap format; and
a display controller configured to cause the display section to display the generated preview image.

### Claim 2 (depends on 1)

The image processing device according to claim 1, wherein
the processing section assigns, based on the raster image data of each of the ink colors, RGB values to individual pixels.

### Claim 3 (depends on 1)

The image processing device according to claim 1, wherein
the special color inks include a white ink and a varnish ink.

### Claim 4 (depends on 1)

The image processing device according to claim 1, wherein
the processing section generates the preview image of an RGB bitmap format by combining the raster image data of the color ink and the raster image data of the special color ink, and
in the raster image data of the special color ink, a color different from a color of the special color inks in a printed state is assigned to a pixel to which the special color ink is to be ejected.

### Claim 5 (depends on 1)

The image processing device according to claim 1, wherein
the processing section generates the preview image of an RGB bitmap format for a group including at least one ink color.

### Claim 6 (depends on 1)

The image processing device according to claim 1, wherein
the preview image is generated in a BMP file format.

### Claim 7 (depends on 1)

The image processing device according to claim 1, wherein
the raster image data is halftone data including a value indicating whether an ink droplet is to be ejected to a pixel or ink amount data of each of the ink colors.

### Claim 8

A preview image display method for causing a display section to display a preview image for printing, the preview image display method comprising:
generating the preview image by converting raster image data of an ink color of a color ink or a special color ink into an RGB bitmap format; and
causing the display section to display the generated preview image.

### Claim 9

A non-transitory computer-readable storage medium storing a preview image display program that causes a computer to realize a function of causing a display section to display a preview image for printing, the program causing the computer to function as:
a processing section configured to generate the preview image obtained by converting raster image data of an ink color of a color ink or a special color ink into an RGB bitmap format; and
a display controller configured to cause the display section to display the generated preview image.
