The work of reproductions and restorations has been developed by continuously innovating state of the art technology to transfer cultural heritage to the next generation. Recently, inkjet printing coupled with pigment inks has become a powerful tool to make replicas of art archives. As original art archives have unique textures, careful attention must be paid so as to reproduce the appearances. In digitizing process of the original with quasi-3D textures, lighting setup should be well considered in conjunction with purposes and circumstances where the replica will be used. Appropriate amount of software retouching is often applied to improve the appearance of the replicas with shade effects. Perceptual illusion of human is taken into account in this retouching process. In some cases, we go back to the time when the original was created and use similar traditional media materials and finishing techniques as the originals have.
