Abstract
A pre-press process employs color accurate instant photography so that the customer and/or his photographer adjust lighting and exposure at the photography session to achieve approved reflection originals. The photographs are judged under controlled lighting against a standard background in device such as a portable illuminator. Since any deficiencies are corrected by recreating an improved original, the session produces a job output which is 100% suitable for color accurate scanning and separation without the intervention of the pre-press operator. Originals are suitable as proofs for the printer to match. Novel means are employed to achieve rapid, colorimetrically calibrated scanning with standard equipment, and the colorimetry of the prior art is improved to deal effectively with whitepoint and blackpoint misalignment.
