A method to predict optical variations from high resolution measurements of paper properties is evaluated in this work. The method combines the point-wise values of high resolution maps of filler content and grammage with an empirical model derived in an earlier study to predict the spatial optical variations in paper. The method has been applied on two paper samples, a laboratory paper and a commercial 80 g/m(2) copy paper. The optical variations have been predicted at a scale of 1 mm(2). Validation has been made by using a high resolution spectrophotometric setup to measure the spatial reflectance variations in the paper. The results show that for the samples used, the influence of filler content variations and density variations on the optical variations is small compared to influence of the grammage variations.
