Abstract:
A method and apparatus to expose photosensitive printing plates with a predetermined radiation density from the main side (top) and a predetermined radiation density from the back side (bottom). The method comprises executing the main exposure with a time delay after the back exposure. The time delay between back exposure and main exposure is optimized to create smaller stable single dot elements on the photosensitive printing plate after processing and smaller single element dot sizes printed on the print substrate. The plate floor may be adjusted by performing a back-side-only exposure prior to executing the combined back and main exposure with the time delay.

Claim (Index 20):
An apparatus for preparing a printing plate comprising a photosensitive polymer activated by exposure to radiation, the printing plate having a non-printing back side and a printing front side with a mask for defining an image to be printed, the apparatus comprising:\n a plurality of radiation sources, comprising a plurality of stationary front sources positioned to expose the front side of the plate to radiation, and a plurality of stationary back sources positioned to expose the back side of the plate to radiation, the plurality of front sources and the plurality of back sources each having an irradiation field covering an area at least coextensive with a length and width of the plate; a holder configured to receive the printing plate in a stationary position to receive incident radiation from the plurality of radiation sources; a controller connected to the plurality of front and back radiation sources, the controller configured to, for each specific coordinate corresponding to a cross-sectional portion of the plate, first (a) commence irradiating the back side of the plate, then (b) automatically impose a precisely defined and repeatable time delay, and then (c) immediately after the time delay elapses, commence irradiating the front side of the plate, without exposing any specific coordinate to front side and back side irradiation simultaneously, the controller configured to adjust floor thickness of the printing plate by providing one or more back-side-only exposure steps prior to performing step (a).
