FIELD: fluid printers, in particular, printing head containing fluid oscillators of various types. SUBSTANCE: the fluid printing head (300) has the first set of fluid oscillators (310) and at least the second set of fluid oscillators (312,314,316). The first set (310) contains a fluid oscillator of the first type (320). Each fluid oscillator of the first type has at least two atomizers and at least two ink injectors connected at least to two atomizers and actually in essence simultaneously. The second set of fluid oscillators has at least on fluid oscillator of the second type (317) with one atomizer. The weight of one drop produced by the fluid oscillators of the first type (320) is not equal to the weight of a drop ejected by the fluid oscillator of the second type (317). The first set of fluid oscillators (310) pushes out ink of the first type, and the second set (312) of fluid oscillators pushes out ink of the second type. To prevent an undesirable mixing of the block and color inks, the first layer (304) of holes or atomizers is made separately and a distance from the second layer (306) of holes. EFFECT: provided use of one printing head for delivery both of black and color inks. 10 cl, 7 dwg |
