Compact hybrid developing machine that exposes a photosensitive substrate (1) using an LED or LCD display (2,3) wherein the substrate (1) is placed in direct contact with the image generating layer (colour generating layer+channelling layer) of the display (2,3). When the display is of LCD technology, the filters (21) of the colour generating layer are placed closer to the substrate (1) than the liquid crystal layer (22). In both types of display (2,3), a channelling layer is installed within the image generating layer, for example, a black matrix (4) of opaque elements. When using an LCD display (2), this may have a unifying filter (24) or a black translucent filter (25) before the light diffusing layer.
