FIELD: printing industry.
SUBSTANCE: invention relates to method for liquid ejection to eject liquid from ejection channel by application of energy to liquid. Method includes the following stages: liquid is put in motion along ejection channel, which comprises, in cross section, relative to direction of ejection, two ledges inside the channel, then liquid surface that is arranged on both sides of two ledges and in area between two ledges in channel in direction opposite to direction of liquid ejection is pulled so that liquid arranged in specified area is joined to liquid in the form of column and is in contact with distal ends of two ledges, and them liquid in the form of column is separated from liquid arranged in specified area to eject liquid from ejection channel, so that liquid arranged in specified area is in contact with distal ends of two ledges.
EFFECT: invention makes it possible to reduce formation of satellites (secondary drops) and to accordingly improve quality of printing.
