Abstract
An apparatus and method for printing a color image from a photographic transparency onto a photosensitive medium is claimed. A plurality of light sources each provide light of a different color when energized. The different color light of each light source has a light intensity level established by an energizing level applied thereto. A light integrator combines the different colored light from the light sources to produce light of a composite color along a primary optical path. The photographic transparency is disposed along the primary optical path such that the composite color light passes through the photographic transparency and produces a projection of the color image from the photographic transparency. An electronic imager is provided for imaging the projected color image of the photographic transparency. A device is provided for exposing the photosensitive medium with the projected color image. A power supply is provided for energizing the plurality of light sources. The power supply provides a first plurality of predetermined energizing levels to the plurality of light sources respectively to produce a first composite color light that substantially compensates for the sensitivity response of the electronic imager. Alternately, the power supply provides a second plurality of predetermined energizing levels to the plurality of light sources respectively to produce a second composite color light that substantially compensates for the sensitivity response of the photosensitive medium.
