Abstract

This study aims at explaining how to design multi-view prints that can show different images in different illumination conditions. A recent reflectance-transmittance optical model for recto-verso halftone prints is extended in order to fasten the calibration step and is used, according to an inversed approach, to design the rectoverso prints displaying the different images in their respective illumination modes. The good prediction accuracy of the model allows creating special effect prints, such as transformation of a binary image in one mode into a second binary image in the second mode, or the transformation of color image into a grey-level version, or the revelation of a message by texture contrast. Regarding the illumination conditions, simultaneous illumination of both sides of the print is allowed. The difficulty of designing such print comes from the fact that the images that are printed on the two sides of the paper are not the images that are displayed, and that the colors displayable in one mode depend on the colors wanted in the other mode. Since no general color management method for these kinds of prints is available, ad hoc methods are proposed for the different effects considered.
