PROBLEM TO BE SOLVED: To reduce the cost by realizing a high speed machine, a standard machine, a low speed machine, a high resolution machine, a low resolution machine, and the like, easily using a plurality of head blocks of identical arrangement. SOLUTION: Head units 11B, 11Y, 11M and 11C of different ink color having identical length, number of nozzles and nozzle pitch are arranged in a direction orthogonal to the print direction thus constituting one head block 11. Four head blocks (11-14) are arranged while being shifted by a length substantially corresponding to the length of the head unit in the direction orthogonal to the print direction such that the nozzles of a head unit second from the end and the nozzles of a head unit at the end are arranged in a row between adjacent head blocks thus constituting a color ink jet head. |
