The purpose of our research is to reproduce the appearance of frangible historical ink paintings for preserving frangible historical documents and illustrations. We, then, propose a method to reproduce both reflectance and transmittance of ink paintings simultaneously by stacking multiple sheets of printed paper. First, we acquire the relationship between printed ink patterns and the optical properties. Then, stacking printed multiple papers with acquired ink pattern according to the measurement, we realize to fabricate a photo-realistic duplication.
