A method for processing a detected eye of an image to provide visual enhancement. The method includes determining whether an eye exists within an image. The eye includes an eye color. If the eye exists within the image, the method also includes determining the location of the eye within the image. Furthermore, the method includes processing the eye to provide visual enhancement to the eye without substantially changing the hue of the eye color of the eye.

One or more ink-usage parameters are adjusted based on ink remaining and historical ink usage, to reduce ink usage for an image to be printed on a sheet of media with ink. The image is printed on the sheet of media with the ink, in accordance with the ink-usage parameters. Adjustment of ink-usage parameters and printing an image on a sheet of media with the ink are repeated for each additional image to be printed on a sheet of media.

A method and apparatus is used for gamut mapping to a printer gamut that includes receiving a narrow gamut, a wide gamut, a printer gamut for printing on a printer and a predetermined mapping between the narrow and printer gamuts, identifying overlapping areas in the wide gamut, the narrow and printer gamuts, determining when the narrow gamut overlaps areas of the wide gamut, utilizing the narrow gamut values when the determination provides overlapping areas of the narrow gamut and the wide gamuts, selecting a wide gamut interpolation point corresponding to the surface of the printer gamut when narrow gamut areas do not overlap the wide gamut according to the determination, selecting a narrow gamut interpolation point by mapping the narrow gamut to the printer gamut and interpolating the narrow gamut interpolation point and the wide gamut interpolation point expanding the narrow gamut values into the printer gamut.

Disclosed are methods of processing digital images to detect previous sharpening of the images by sequentially examining characteristics of individual pixels within the image and the neighborhood of pixels immediately surrounding the individual pixels. Detection of previous sharpening allows detrimental oversharpening to be avoided. Also disclosed are methods of determining whether a digital image has been previously sharped and, based upon that determination, selectively sharpening the image.

A method for compensating for induced artifacts on an image to be printed includes processing the image to be printed. An image region of the image susceptible to at least one artifact is identified. An imaging process is modified to reduce an effect of the at least one artifact on the image region. The image is printed.

An ink set for inkjet printing includes a cyan ink having a first lightness value, a magenta ink having a second lightness value, and a blue ink having a third lightness value, wherein the cyan ink and the magenta ink mix to form a composite blue having a fourth lightness value, wherein the fourth lightness value is approximately twice the third lightness value.
