Patent ID: 7850268

Claim:
A recording method for recording by using a recording head having a nozzle array including a plurality of nozzles based on recording data, the nozzles being divided into a plurality of groups, the nozzles included in each of the plurality of groups being divided into a plurality of blocks and by driving each block time-divisionally, the method comprising: generating a timing signal periodically, for generating a plurality of the timing signals within a predetermined time period, based on a scanning speed of the recording head and a resolution of the recording with regard to a scanning direction; determining, for each group, a timing signal to be driven and a timing signal not to be driven, with regard to each timing signal of the plurality of the timing signals, according to information on misalignment of the nozzle array; reading the recording data of one column from a recording buffer in accordance with the predetermined time period; rearranging the recording data read in the reading step corresponding to the block; assigning, for each group, null data to the timing signal not to be driven and the recording data to the timing signal to be driven, based on a result of the determining; and driving the recording head in synchronization with the timing signal by block, based on data assigned to each group.
