Abstract
The invention relates to apparatus for the manufacture of a photographic print on a copier material, whereby an exposure arrangement is provided with a projection optic for the manufacture of the photographic print, which includes a mirror matrix with individually movable mirrors, whereby the exposure arrangement includes a broadband light source, for example a halogen light source, whereby a filter arrangement for filtering or letting pass certain spectral portions or certain amounts of light is positioned in the light path between the light source and the mirror matrix.
Claims8
Apparatus for the manufacture of a photographic print on a light sensitive copier material, comprising:
- a scanner for producing image data from an original;
- an image data processing arrangement for processing the image data into control signals;
- and
- an exposure arrangement having a projection optic for projecting an optical representation of the image data onto the copier material according to the control signals, wherein the exposure arrangement further comprises a mirror matrix with individually movable mirrors, an illumination arrangement, and a filter arrangement positioned in a projection light path between the light source and the mirror matrix, for separating out preselected spectral ranges of light from the light produced by the light source;
- wherein the projection optic includes movable components for permitting a relative movement between a strip shaped exposure region of the original and the copier material;
- and
- wherein the movable components are first, second and third redirecting mirrors and the apparatus further comprises drive means for linearly moving the redirecting mirrors parallel to the copier material and perpendicular to a longitudinal direction of the strip shaped exposure region of the original, wherein the first and second redirecting mirrors are in a fixed spatial arrangement relative to one another and redirect the light in a projection light path by 180°, the third redirecting mirror is positioned antiparallel to the second redirecting mirror and redirects the light in the light path perpendicularly onto the copier material, and the drive means are constructed for moving the third redirecting mirror at twice the speed of the first and second redirecting mirrors.
