An image processor comprising: a first determining unit (11, S102) configured to determine whether or not a prescribed setting is set for image data including a plurality of input color values, an image which corresponds to the image data, having a plurality of regions adjacent to each other, the plurality of input color values corresponding to the plurality of regions, respectively, the image data being subjected to a color conversion process for converting the plurality of input color values to a plurality of output color values, each of the plurality of output color values indicating color value of a colorant used for printing the image, a converting unit (11, S103, S105) configured, when the determining unit determines that the prescribed setting is not set for the image data, to execute the color conversion process for the image data according to a normal profile, and configured, when the determining unit determines that the prescribed setting is set for the image data, to execute the color conversion process for the image data according to a colorant-saving profile configured such that an amount of colorant to be used in the colorant-saving profile is smaller than that in the normal profile; characterised in that: the image processor further comprising a second determining unit, and wherein the image data has object data corresponding to an object to be printed in the image, wherein the second determining unit (11, S203, S206) is configured to determine a type of the object, wherein the colorant-saving profile includes a plurality of colorant-saving profiles, wherein the converting unit (11, S305, S306, S308, S310, S311) is configured to execute the color conversion process according to one of the plurality of colorant-saving profiles that depends on the determined type of the object, wherein the plurality of colorant-saving profiles includes a first text colorant-saving profile configured such that a ratio of the colorant amount used for a text color in the first text colorant-saving profile to the colorant amount used for the text color in the normal profile is greater than a ratio of the colorant amount used for a color other than the text color in the first text colorant-saving profile to the colorant amount used for the colors other than the text color in the normal profile, the text color being preset as a color to be used for text, and wherein the converting unit (11, S305) is configured to execute the color conversion process according to the first text colorant-saving profile when the type of the object is determined as a text by the second determining unit. a first determining unit (11, S102) configured to determine whether or not a prescribed setting is set for image data including a plurality of input color values, an image which corresponds to the image data, having a plurality of regions adjacent to each other, the plurality of input color values corresponding to the plurality of regions, respectively, the image data being subjected to a color conversion process for converting the plurality of input color values to a plurality of output color values, each of the plurality of output color values indicating color value of a colorant used for printing the image, a converting unit (11, S103, S105) configured, when the determining unit determines that the prescribed setting is not set for the image data, to execute the color conversion process for the image data according to a normal profile, and configured, when the determining unit determines that the prescribed setting is set for the image data, to execute the color conversion process for the image data according to a colorant-saving profile configured such that an amount of colorant to be used in the colorant-saving profile is smaller than that in the normal profile; characterised in that: the image processor further comprising a second determining unit, and wherein the image data has object data corresponding to an object to be printed in the image, the image processor further comprising a second determining unit, and wherein the image data has object data corresponding to an object to be printed in the image, wherein the second determining unit (11, S203, S206) is configured to determine a type of the object, wherein the colorant-saving profile includes a plurality of colorant-saving profiles, wherein the converting unit (11, S305, S306, S308, S310, S311) is configured to execute the color conversion process according to one of the plurality of colorant-saving profiles that depends on the determined type of the object, wherein the plurality of colorant-saving profiles includes a first text colorant-saving profile configured such that a ratio of the colorant amount used for a text color in the first text colorant-saving profile to the colorant amount used for the text color in the normal profile is greater than a ratio of the colorant amount used for a color other than the text color in the first text colorant-saving profile to the colorant amount used for the colors other than the text color in the normal profile, the text color being preset as a color to be used for text, and wherein the converting unit (11, S305) is configured to execute the color conversion process according to the first text colorant-saving profile when the type of the object is determined as a text by the second determining unit.
