Abstract:
1. A recording apparatus for effecting recording on a recording medium by scanning a recording head for discharging plural colors of inks with respect to the recording medium, the recording apparatus comprising: an obtaining unit configured to obtain information on a relative relation between amounts of inks of the plural colors to be discharged for each of plural unit areas based on M-valued data corresponding to each of the plural colors of inks with respect to each of the plural unit areas, the unit areas being provided by dividing an area in a neighborhood of a boundary between adjacent bands recorded on the recording medium by scanning of the recording head; a determining unit configured to determine, for each of plural colors of inks, a reduction rate for reducing a value of the M-valued data corresponding to each of the plural colors of inks corresponding to a predetermined area within the unit area based on the information on the relative relation obtained by the obtaining unit and based on information on a total ink amount of the plural colors of inks; a reducing unit configured to reduce the value of the M-valued data corresponding to each of the plural colors of inks corresponding to the predetermined area based on the reduction rate for each of the plural colors of inks determined by the determining unit; and a converting unit configured to convert the M-valued data of which the value was reduced by the reducing unit corresponding to each of the plural colors of inks into N-valued data, M being greater than or equal to N, corresponding to each of the plural colors of inks for discharging each of the plural colors of inks by the recording head.
