Abstract
In an image formation apparatus, a matching engine converts the color in image data for a color image into an output color, a specific color determining device determines whether the color in the image data is a color (specific color) indicated by a point on a straight line connecting between an origin point and a point indicating an ink color in a color space, and a color profile interpolates the image data determined as the specific color only with other specific colors on the straight line where the specific color is located.
Claims20
An image formation apparatus comprising:
- a color converting unit that converts a color in image data into an output color when a color image is to be output by using a plurality of ink colors or by mixing the ink colors;
- and
- an image data color determining unit that determines whether the color in the image data is a specific color, being a color indicated by a point on a straight line connecting between an origin point and a point indicating the ink color in a color space, or a non-specific color other than the specific color,
- wherein when the color in the image data is to be interpolated, the color converting unit interpolates the image data determined as the specific color by the image data color determining unit, only with other specific colors on the straight line where the specific color is located.
A program for allowing a computer to execute an image formation method, the method comprising steps of:
- converting a color in image data to an output color when a color image is to be output by using a plurality of ink colors or by mixing the ink colors;
- and
- determining whether the color in the image data is a specific color, being a color indicated by a point on a straight line connecting between an origin point and a point indicating an ink color in a color space, or a non-specific color other than the specific color, wherein
- when the color in the image data is to be interpolated, the color converting step includes interpolating the image data determined as the specific color at the determining step, only with other specific colors on the straight line where the specific color is located.
