FIELD: printing.
SUBSTANCE: present invention relates to a printhead for thermographic inkjet printing containing a liquid supply channel intended for liquid delivery, liquid chambers located near the liquid supply channel, resistors intended for introducing liquid into chambers located in ledges relative to the vertical lines of the printing contact. At least a portion of the fluid supply channel opposite the back of the printhead runs substantially perpendicular to the surface of the microcircuit, and the fluid channel has unevenly spaced edges that follow ledges relative to the resistors such that the length of the fluid path between the edge of the resistor and the corresponding unevenly spaced edge is essentially the same for each resistorа.
EFFECT: claimed invention is aimed at providing compensation for variations in the behavior of the liquid of electronic sections, in order to increase print head frequency.
