Sažetak
The problem of light dispersion on the determined substrate under the pressed element was investigated and simulated on the model according to the realistic situations obtained by the printing technique of the offset print. The Monte Carlo simulation of the light transport was used on the paper using the method of the construction of the stochastic models. By means of the technique of decreased variation the photon emission was determined, which through the pre-determined parameters describes the dispersion and defines the values of the simulated values. The paper uses the definition presented by Lux and Koblinger due to the expected values of random variables, which were used as the equivalent to the realistically required values. The estimate of the photon number was simulated, which is positioned under the pressed element and causes the possible optical increase of the grid tone value due to the introduction of the filters as the permanently lost number of photons.
