Patent ID: 7973969

Claim:
A printing apparatus comprising: a printing section that performs printing on a print target medium; a display unit that displays various kinds of information; a touch-sensitive panel that is overlaid on a surface of the display unit and detects a position touched by a user; a display controlling section that controls the display unit so as to display a red cell block, a green cell block, and a blue cell block, the red cell block comprising an array of a plurality of red display cells in which a value of a red color component changes stepwise from a base set of values of red, green, and blue, the base set of values being a set of red, green, and blue values that is recognized by the user as an apparent red base color when shown on the display unit and observed through the touch-sensitive panel, the green cell block comprising an array of a plurality of green display cells in which a value of a green color component changes stepwise with a set of values of red, green, and blue, the base set of values being a set of red, green, and blue values that is recognized by the user as an apparent green base color when shown on the display unit and observed through the touch-sensitive panel, the blue cell block comprising an array of a plurality of blue display cells in which a value of a blue color component changes stepwise with a set of values of red, green, and blue, the base set of values being a set of red, green, and blue values that is recognized by the user as an apparent blue base color when shown on the display unit and observed through the touch-sensitive panel; a three-primary-color correcting section that sets a corrected set of values that is recognized by the user as the apparent red base color, a corrected set of values that is recognized by the user as the apparent green base color, and a corrected set of values that is recognized by the user as the apparent blue base color, on the basis of a comparison made between a position of each of the red display cells in the red cell block, a position of each of the green display cells in the green cell block, and a position of each of the blue display cells in the blue cell block and a touch position detected by the touch-sensitive panel, respectively; and a print controlling section that controls the printing section to print a true red base color, a true green base color, and a true blue base color as a color sample that is used when the three-primary-color correcting section performs correction.
