and applying a composition to the keratinous material, the composition modifying a characteristic of the appearance of said keratinous material so as to give it an optical characteristic intermediate between the measured optical characteristics. ## Claims ### Claim 1 A method of applying make-up to a human keratinous material, the method comprising: taking at least two measurements of a color of the keratinous material at different location; determining an optical characteristic forming an intermediate color and shades thereof that are intermediate between the at least two measurements of a color, where the intermediate color is an average or weighted average of the at least two measurements of color of the keratinous material; and applying a cosmetic deposit to the keratinous material, the cosmetic deposit being the intermediate color the cosmetic deposit being applied between at least two locations at which the color of the keratinous material has been measured, the color of the cosmetic deposit varying and shading off gradually between the at least two locations where the color was measured lying between the at least two measured colors of the keratinous material, the color of the cosmetic deposit varying on approaching edges of the cosmetic deposit so as to come close to the color of the keratinous material in a vicinity of the cosmetic deposit. ### Claim 2 (depends on 1) The method according to claim 1, wherein the cosmetic deposit includes one or more cosmetic inks. ### Claim 3 (depends on 1) The method according to claim 1, wherein the intermediate color is an average color. ### Claim 4 (depends on 1) The method according to claim 1, wherein the measurements and the application of the cosmetic deposit are performed by a single handpiece. ### Claim 5 (depends on 1) The method according to claim 1, wherein the measurements are performed at locations that are spaced apart by a distance having a range of 5 mm to 50 mm. ### Claim 6 (depends on 1) The method according to claim 1, wherein the color of the cosmetic deposit includes at least two different cosmetic inks. ### Claim 7 A device for making up a human keratinous material, the device comprising: an acquisition system including at least two color sensors which are spaced apart and configured to obtain at least two measurements of a color of the keratinous material at different locations, a processor programmed to determine an optical characteristic forming an intermediate color and shades thereof that are intermediate between the at least two measurements of a color where the intermediate color is an average or weighted average of the at least two measurements of color of the keratinous material; and a printer system comprising a plurality of cosmetic inks for creating the optical characteristic; wherein the printer system is configured to apply the cosmetic inks having the intermediate color and shades thereof as a cosmetic deposit to the keratinous material in an area between the different locations, wherein the intermediate color is applied at a specific location between the two different locations and the shades thereof vary gradually between the intermediate color and the colors at the two different locations the intermediate color varies on approaching edges of the cosmetic deposit so as to come close to the color of the keratinous material in a vicinity of the deposit, and the device houses a handpiece that includes the acquisition system and the printer system. ### Claim 8 (depends on 7) The device according claim 7, further comprising: an interface enabling a user to modify the color of the cosmetic deposit prior to printing. ### Claim 9 A device for making up a human keratinous material, the device comprising: an acquisition system enabling at least two measurements of a color of the keratinous material to be performed at different spaced apart locations via color sensors, a processor programmed to determine an optical characteristic forming an intermediate color and shades thereof that are intermediate between the at least two measurements of a color where the intermediate color is an average or weighted average of the at least two measurements of color of the keratinous material; and a printer system comprising a plurality of cosmetic inks for creating the optical characteristic; wherein the printer system is configured to apply the cosmetic inks having the intermediate color and shades thereof as a cosmetic deposit to the keratinous material in an area between the different locations, wherein the intermediate color is applied at a specific location between the two different locations and the shades thereof vary gradually between the intermediate color and the colors at the two different locations the intermediate color varies on approaching edges of the deposit so as to come closer of the keratinous material in a vicinity of the deposit, and the printer system includes a vibrator configured to create a fuzziness on application.
