Abstract
Abstract An apparatus for calibrating a printer of a photofinishing system, comprising: (a) a reference film strip carrying at least one reference image; (b) a reference chart carrying multiple renderings of the reference image representing different printer exposures; and (c) a substrate carrying printer correction factors needed to change a photographic print obtained from the reference image on the reference film strip, to match any desired rendering on the reference chart. A method of producing the above reference chart, and a method of calibrating a printer of a photofinishing system, are also provided.
