Optical representations of differing strip-shaped portions of an original are successively produced by way of an electro-optical converter operating pixel- by-pixel for the manufacture of a photographic print from an original present in electronic form. The optical representations are exposed onto the copy material in a strip-shaped exposure region, whereby the strip-shaped exposure region and the copy material are moved relative to one another at a constant speed and in a direction transverse to the longitudinal extent of the strip-shaped exposure region. In this way, the image information of the whole original is successively exposed onto the whole available surface of the copy material. A digital micro mirror array is preferably used as the electro-optical converter. The electro-optical converter is positioned in the exposure light path in such a way that its rows and columns extend at an angle of essentially 45E to the longitudinal extent of the strip shaped exposure region. A strip- shaped pixel region of the converter oriented essentially in the diagonal of the converter is thereby used for the production of the optical reproductions of the step- shaped portions of the original. Thus, the strip-shaped optical image representation of the strip-shaped portions of the original extend along the diagonal of the converter, which results in a higher resolution for the same converter since a larger number of pixels are available for production of the same image. Larger print formats can be achieved with commercially available converters and substantially without a loss in quality.
