Abstract
It is often difficult to obtain quality hard copy for high resolution (eg. 6000×3000 pixels) digital images. To obtain hard copy, we use a film recorder which writes a fine image raster directly onto Polaroid instant color print film. Our concern that the color in the print be controlled as precisely as possible led to the development of a special purpose color computer. The color computer resides in the film recorder and transforms the input image pixel values into those output exposure control values necessary to attain the desired color on film. This color transformation is done on the fly without slowing down the printing of the image.
