DEVICE OF IMAGE FORMATION AND PRINTING PRODUCTION Russian patent published in 2009 - IPC B41J2/45 

FIELD: printing industry.

SUBSTANCE: claimed invention relates to device of image formation and printing production. Device of image formation contains head of liquid discharge, in which nozzles for liquid drops discharge are arranged close to each other, unit for formation of oscillating signal of excitation, forming in range of one cycle of excitation first oscillating signal of excitation, which contains signal of excitation for discharge of liquid drop volume, which is used for image formation, and second oscillating signal of excitation, which contains excitation signal for liquid drop volume discharge, smaller than minimal discharge drop volume, used for image formation. Unit of head control impels head of liquid discharge to discharge volume of drop of liquid, used for image formation, according with first oscillating signal of excitation for area, where image is formed, and to discharge liquid drop volume, smaller than minimal discharged drop volume in accordance with second oscillating signal of excitation for area, where picture is not formed.

EFFECT: creation of improved device of image formation, in which shortcomings of previous level of technology are eliminated.
