Flux transfer model for designing visual effects by halftone printing

By extending classical reflectance prediction models for halftone prints according to a spectral mixing model based on a two-flux layering approach, we can predict simultaneously the reflectances and transmittances of simple halftone prints as well as compositions of various supports printed with different halftones, made of strongly scattering or almost non-scattering materials. The calibration of the model needs no more than a few tens of macroscopic spectral measurements, whereas thousands or billions of sample measurements would need to be measured without the model. The prediction accuracy was satisfyingly verified through recto-verso printed papers and stacks of printed films viewed in reflectance or transmittance mode. The model enables conceiving innovative applications for graphical arts.
