发明名称 Ink-jet recording methods and apparatuses
摘要 An ink-jet recording apparatus includes recording head having a plurality of recording elements and performs image recording by the steps of detecting a presence of black dots in a prescribed amount of input data and calculates a percentage of black dots, selecting a suitable recording mode for forming an image of the prescribed amount of input data on the recording medium in response to a result of the calculation, and controlling a drive condition of the recording head in accordance with the selected mode. When the percentage of the black dots exceeds a prescribed level, the recording head is driven so as to remove some dots from a total number of dots corresponding to the prescribed amount of the input data or reducing thermal energy to be supplied to the thermal elements in the cause of the image recording.
