  • Publication number: 20040135982
    Abstract: In an apparatus for producing images on a light-sensitive material, the graphic information content for an image that is to be projected onto the light-sensitive material is divided into individual pixels. The projected image is composed of mutually offset partial images that are represented in a transmissive device consisting of an array of transmissive elements. The apparatus includes a light source that generates light rays passing through the transmissive device, an illumination device that bundles the light rays into light beams before they pass through the transmissive device, and a projection objective that projects the light beams telecentrically onto the light-sensitive material.

  • Patent number: 6759175
    Abstract: An method is disclosed for on-site preparation of a relief image comprising the following steps: (a) laminating a material comprising, in the order given, a first peelable support (1), an image recording layer (2) and an adhesive layer (3) onto a UV-sensitive material comprising a support (7), an UV-sensitive layer (6) wherein the adhesive layer (3) is laminated to the UV-sensitive layer (6); (b) image-wise exposing the image recording layer (2) to form a mask; (c) flood exposing the UV-sensitive material through the mask; (d) developing the UV-sensitive material; wherein the peelable support (1) is removed either before step (b), (c) or (d). Steps (a) to (d) are performed within a period of less than 2 months. As a result the extent of monomer diffusion from the UV-sensitive layer to the image recording layer is reduced. Additionally the adhesion between the image recording layer and the UV-sensitive material is optimised.
