    Abstract: A process for creating a flexographic plate or a mask for producing a flexographic plate, including providing a screen having a resolution defined by a base pattern of equally sized screen spots, each screen spot comprising a smallest exposed discrete element represented on the screen. In at least a non-solid tonal portion of the plate or mask, the size of physical spots are selectively modulated such that each set of four neighboring physical spots in the base pattern has an unexposed area centered therebetween. Each screen spot in the base pattern may be an exposed pixel surrounded by 8 unexposed pixels, each physical spot corresponding to the resolution of a laser beam for exposing the spots on the mask, in which the imaging step includes boosting power of the laser beam for isolated pixels relative to non isolated pixels. Mask and plates, and imaging systems for creating them, are also disclosed.

  • Patent number: 11020956
    Abstract: Ink-based digital printing systems useful for ink printing include a photoreceptor layer configured to receive a layer of liquid immersion fluid. The liquid immersion fluid includes dampening fluid, dispersed gas particles, and charge directors that impart charge to the solid particles. The photoreceptor surface is charged to a uniform potential, and selectively discharged using an ROS according to image data to form an electrostatic latent image. The charged liquid immersion fluid adheres to portions of the photoreceptor surface according to the electrostatic latent image to form a fountain solution image. The fluid portion of the fountain solution image can be partially transferred to an imaging member and/or transfer member to form a dampening fluid image, either or both of which may be electrically biased. The dampening fluid image is inked on the transfer member, and the resulting ink image transferred to a print substrate.
