    Abstract: An exposure apparatus that scans and exposes each of a plurality of areas on a glass substrate, by irradiating the substrate with an illumination light via a projection optical system and relatively driving the substrate with respect to the illumination light, is equipped with: a substrate holder that levitates and supports a first area of the substrate; a substrate carrier that holds the glass substrate levitated and supported by the substrate holder; an X coarse movement stage that drives the substrate holder; an X voice coil motor that drives the substrate carrier; and a controller that controls the X coarse movement stage and the X voice coil motor so that the substrate holder and the substrate carrier are driven, respectively, in scanning exposure. Accordingly, an exposure apparatus with improved position controllability of an object can be provided.

    Abstract: Described is a method for producing flexographic printing plates, using as starting material a photopolymerizable flexographic printing plate which contains a dimensionally stable support, a photopolymerizable, relief-forming layer, and a digitally imagable layer. A mask is produced by imaging the digitally imagable layer. The printing plate is exposed with actinic light through the mask. The image regions of the layer are photopolymerized. A plurality of UV-LEDs are arranged on at least one UV-LED strip which is moved relative to the surface of the flexographic printing plate for exposure. The photopolymerized layer is developed by washing out and drying or by thermal development. An ultrasonic sensor determines the thickness of the flexographic printing plate for exposure. The exposure is controlled as to number of exposure steps, exposure intensity, energy input per exposure step, duration of individual exposure steps, and/or overall duration of exposure.

    Abstract: A method of making a relief image printing element from a photosensitive printing blank is provided. A photosensitive printing blank with a laser ablatable layer disposed on at least one photocurable layer is ablated with a laser to create an in situ mask. The printing blank is then exposed to at least one source of actinic radiation through the in situ mask to selectively cross link and cure portions of the photocurable layer. Diffusion of air into the at least one photocurable layer is limited during the exposing step and preferably at least one of the type, power and incident angle of illumination of the at least one source of actinic radiation is altered during the exposure step. The resulting relief image comprises a plurality of dots and a dot shape of the plurality of dots that provide optimal print performance on various substrates, including corrugated board.

    Abstract: The present invention relates to an exposure device which forms an image of a pattern on a mask onto a substrate with microlens arrays to expose the substrate, and reduces a size of an lighting unit which emits an exposure light. Microlens arrays include plural microlenses which are arranged two-dimensionally and arranged in a direction intersecting a movement direction. Lighting unit includes an LD array bar in which plural laser diodes are arranged, and lighting optical system which transforms plural emitted lights emitted from the plural laser diodes into an exposure flux having a slit form. The slit form spreads across plural pieces of the microlenses, and which, with respect to the movement direction, is limited in an area not reaching a microlens arranged in an adjacent row in the movement direction, and illuminates plural microlenses arranged in a row with an exposure light by the exposure light flux.
