Abstract [en]

A large number of optical properties in paper and print are determined by measuring the light reflected from an illuminated paper surface. These measurements are interpreted through a model, and the one that has been in use in the paper industry since the 1930’s (Kubelka-Munk) is deficient in some respects. This paper presents a selection of issues that will be in focus for future optical modeling, and shows what the next generation simulation tools may look like.

The anisotropy of the scattered light becomes increasingly important, and this will open up a large area of research that will both explain a number of outstanding issues and open for a new kind of material property design. Physically objective material parameters will be introduced instead of phenomenological model parameters. The wish to model the real structure of paper and printed paper products instead of homogenized approximations will drive the development of Monte Carlo models with greater explanative power, which in turn will give an increased need for characterization methods. Differences in optical standards between the paper and graphic arts industries will force harmonization or models for data exchange. The treatment of UV and fluorescence will be included in both light scattering simulation tools and color management tools, and there will be attempts of merging these two types of tools, which will open for another view on color reproduction. The directions of development outlined above are exemplified with recent results.
