  • Patent number: 8733921
    Abstract: Disclosed is a method and apparatus for improving printed image quality. The image quality improvement is achieved by differentially curing different image elements such as continuous tone elements, uniform tinted and solid elements, color elements, line art and text elements. A delay in the activation, duration and variation in the intensity of the curing radiation or a mix of some or all of them that follows the ink droplet on substrate deposition controls the ink droplet spread and accordingly the image quality.

  • Patent number: 6474783
    Abstract: A printing device including a laser for generating at least one laser beam, a controller, a print head having a plurality of orifices, and an ink supply for supplying ink to the print head. The controller modulates the at least one modulated laser beam according to image data to be printed. The at least one modulated laser beam selectively generates a directional acoustic wave within the print head, thereby inducing an ink droplet to exit a selected one of the orifices onto a printing substrate. A print head including a single buffer chamber, a body, and a single ink chamber. The buffer chamber stores a buffer liquid therein with the body forming one wall of that chamber. The ink chamber shares the body as a wall. The ink chamber stores ink therein and has a plurality of orifices on a wall opposite to the body.

  • Patent number: 6125751
    Abstract: A duplex color web press, wherein each section, which prints both faces of the web with any one ink type and color, is configured with a single printing cylinder and, in the case of a digitally recording press, with a single recording head. The single printing cylinder carries the inking versions of both the recto and verso images around its circumference and the web is routed through two printing stations, both associated with the single printing cylinder, so that one of its faces is imprinted in one station and the other face--in the other station. The resultant print on each face is alternating recto and verso images, such that a recto image on one face is in the back of a verso image on the other face, and vice versa.
