Fast-Calibration Reflectance-Transmittance Model to Compute Multiview Recto-Verso Prints

摘要

Predicting simultaneously the spectral reflectance and transmittance of recto-verso prints is made easier thanks to a flux transfer matrix model. In the case where the printing support is symmetrical, i.e., its two sides are similar, the model can be calibrated from 44 halftone colors printed on the recto side, whose spectral reflectances and transmittance are measured. Color predictions are then allowed for any recto-verso halftone print illuminated on either side, and the inverse approach can be addressed: we can compute the digital layout for the recto and verso side that, once printed, can display different images according to the illuminated side.
