Contact Printing
The method used by the lab to copy film. A contact print is made on a machine called (sensibly enough) a Contact Printer, in which the original film and unexposed print stock are sandwiched together, emulsion against emulsion, and are run at a constant speed past a light which shines through the original, exposing the print stock with the same image. All workprints, answer prints and release prints are contact prints. The only other type of printing is Optical Printing, which is usually done to add an effect or to blow up or make a reduction print.
