Abstract
The present invention provides a print head capable of ejecting a fluid, containing at least ink, toward a printing medium for printing. The print head has an ink chamber for receiving the ink, a diluent chamber for receiving a diluent for diluting the ink, an ink orifice fluidly connected with the ink chamber for ejecting or oozing out a predetermined quantity of the ink, and a diluent orifice fluidly connected with the diluent chamber for ejecting or oozing out a predetermined quantity of diluent. The ink chamber and the diluent chamber are provided separately from each other and the ink orifice and diluent orifice are provided separately from each other. In addition, the present invention provides a process for making a print on a printing medium by using an ink ejected from a print head, the print head has an ink chamber and a diluent chamber. The process includes the steps of providing a pair of pressure-applying elements at positions corresponding to the ink chamber and the diluent chamber, impressing a quantity-determinative pulse to the pressure-applying element disposed at a position corresponding to the ink chamber, and impressing an ejecting pulse to the pressure-applying element disposed at a position corresponding to the diluent chamber.
