A simulation model was developed for a dye mixing process and for the prediction of the optical properties of the paper. The model was integrated with the MAPPS (Modular Analysis of Pulp and Paper Systems) simulation software package. The model was validated using dyed handsheets made in a laboratory and dyed paper made on a pilot papermachine. Validation comprised of prediction of the optical properties of the handsheets and the machine-made paper which contained various combinations of three non-fluorescent dyes. Sheet reflectances were predicted at 20 nanometer intervals for discrete light wavelength range of 400 to 700 nanometers and verified experimentally. in addition, for the combinations of illuminants C and D65 and the CIE 2 and 10 degree standard observers, the CIE L, a*, and b* color coordinates were predicted and experimentally verified.
Under the conditions investigated, the model was able to predict the optical properties of paper accurately.
