Abstract:
An ink-jet printing apparatus for performing printing on a printing medium by selectively using at least cyan ink having a first coloring-material density, magenta ink having a first coloring-material density, cyan ink having a second coloring-material density lower than that of the cyan ink having the first coloring-material density, and magenta ink having a second coloring-material density lower than that of the magenta ink having the first coloring-material density, said apparatus comprising:first printing mode executing means for performing printing by using at least the cyan ink having the first coloring-material density and the magenta ink having the first coloring-material density without using the cyan ink having the second coloring-material density and the magenta ink having the second coloring-material density;second printing mode executing means for performing printing by using at least the cyan ink having the first coloring-material density, the magenta ink having the first coloring-material density, the cyan ink having the second coloring-material density and the magenta ink having the second coloring-material density; anda mounting section for selectively mounting a plurality of ink tanks for the cyan ink having the first coloring-material density, the magenta ink having the first coloring-material density, the cyan ink having the second coloring-material density and the magenta ink having the second coloring-material density,wherein when said first printing mode executing means performs printing, at least the ink tanks for the cyan ink having the first coloring-material density and the magenta ink having the first coloring-material density are mounted on said mounting section and the ink tanks for the cyan ink having the second coloring-material density and the magenta ink having the second coloring-material density are not mounted on said mounting section, and when said second printing mode executing means performs printing, at least the ink tanks for the cyan ink having the first coloring-material density, the magenta ink having the first coloring-material density, the cyan ink having the second coloring-material density and the magenta ink having the second coloring-material density are mounted on said mounting section.
