摘要:
A phosphor panel with a protective coating divided in at least two layers: a layer A, being closest to said phosphor layer and a layer B farther away from said phosphor layer wherein the layer A has a lower water vapour permeability coefficient than the layer B. Layer A has a water vapour permeability coefficient, P, so that 0 ≤ P ≤ 1 × 10 - 11 cm 3 ( STP ) · cm cm 2 · s · Pa .
摘要:
A direct-to-plate method for obtaining a high quality lithographic printing plate is disclosed. The method comprises the application of a continuous layer of a radiation sensitive solution onto a lithographic substrate by means of an ink-jet printhead. Hereby waste of coating solution and contamination of the environment are avoided.
摘要:
A single pass printer, having a printing width (PW) is provided for printing a toner image on a substrate, the substrate having a width (WS) and a length (LS), wherein, i) a number n, equal to or larger than 2, of printing engines, each containing a toner transferring element with a longitudinal axis (width (WPE)) smaller than the printing width (PW) are present, and at least two of the n printing engines, each containing a toner transferring element with a longitudinal axis in the direction of width (WPE), are located so that the longitudinal axis do not coincide. Preferably the printing engines are electro(stato)graphic engines, especially Direct Electrostatic Printing (DEP) engines or electrophotographic engines.
