Printing system, method of recording images, and ink cartridge attachable to printing system

A printing system for recording at least three different color inks, which are mixed to express hues in a predetermined range, on a printing object,

• wherein a density ratio of a specific color ink, which has lowest conspicuousness of granularity at a fixed recording ratio of a number of dots per unit area among said at least three different color inks, to the other color inks is determined, in order to enable a color balance to be biased to said specific color ink having the lowest conspicuousness of granularity in case that said specific color ink and the other color inks have an identical recording ratio of a number of dots per unit area,
• said printing system comprising:
• a printing head which prints with said color inks on said printing object;
• a correction controller configured to correct a recording amount of said specific color ink having the lowest conspicuousness of granularity to a level that cancels said bias.

A printing system for printing at least three different color inks, wherein the at least three different color inks are mixed to express hues in a predetermined range on a printing object, the printing system comprising:

• a first ink reservoir containing a specific color that has highest lightness at a same recording ratio of a number of dots per unit area among the at least three different color inks;
• at least two second ink reservoirs containing the at least two color inks other than the specific color ink, respectively, wherein a concentration ratio of the specific color ink to the at least two color inks is determined such that a color balance is biased to the specific color ink when the specific color ink and the at least two color inks have an identical recording ratio of a number of dots per unit area in order to reduce a total amount of the color inks on the object;
• a correction controller configured to reduce a recording amount of the specific color ink to a level that cancels the bias;
• and
• a printing head discharging the at least three color inks on the printing object.

An ink cartridge attached to a printer for recording different color inks, which are mixed to express hues in a predetermined range, said ink cartridge comprising:

• a yellow ink reservoir containing a yellow ink;
• a cyan ink reservoir containing a cyan ink;
• a magenta ink reservoir containing a magenta ink;
• wherein a density of ratio of the yellow ink to the cyan and magenta inks is determined, to enable a color balance to be biased to the yellow ink in case the yellow, cyan, and magenta inks have an identical recording ratio of a number of dots per unit area.

An ink cartridge attached to a printer for recording different color inks, which are mixed to express hues in a predetermined range, said ink cartridge comprising:

• a yellow ink reservoir containing a yellow ink;
• a cyan ink reservoir containing a ink;
• a magenta ink reservoir containing a magenta ink;
• a light cyan ink reservoir containing a light cyan ink, wherein a density of the light cyan ink is lower than a density of the cyan ink;
• a light magenta ink reservoir containing a light magenta ink, wherein a density of the light magenta ink is lower than a density of the magenta ink;
• wherein a density of ratio of the yellow ink to the cyan and magenta inks is determined, to enable a color balance to be biased to the yellow ink in case the yellow, cyan, and magenta inks have an identical recording ratio of a number of dots per unit area.
