FIELD: printing.
SUBSTANCE: invention relates to systems for ink keeping and feeding. Proposed system includes ink source with first pressure regulator arranged higher in direction of ink flow which maintains negative ink pressure inside ink source. Second pressure regulator of printing head arranged lower in direction of flow maintains negative ink pressure in said printing head and provides pliability near point of mounting. Ink keeping and feeding system makes it possible to separate ink source from printing head without leaks of ink. System maintains high flow rates of ink and provides "impulse" flow rates (maintained at short time intervals) and transporting of air bubbles along system channels to printing head at simultaneous maintaining of ink pressure in printing head within range required for optimum operation of printing head.
EFFECT: improved quality of printing.
