An inkjet head includes: a first nozzle that jets pigmented ink; a first pressure chamber coupled to the first nozzle; a first actuator that selectively applies a jetting pressure to the pigmented ink in the first pressure chamber; a second nozzle that jets dye ink; a second pressure chamber coupled to the second nozzle; and a second actuator that selectively applies a jetting pressure to the dye ink in the second pressure chamber. The first nozzle has a diameter Dand the second nozzle D. The first actuator has a first portion that applies the jetting pressure to the first pressure chamber, which has a size L. The second actuator has a second portion that applies jetting pressure to the second pressure chamber, which has a size of L. D, D, Land Lsatisfy the following formula: −xD+yL≈−xD+yL, where x and y are predetermined coefficients.
