Summary:
The profile of the printing elements is the most important quality characteristic of the photopolymer plate. In this work the profile was determined by using the Fourier transform analysis. The photopolymer plate is considered as multi layers system. The exposing light scattering was evaluated by calculating of the transform characteristics of the system for making the printing plate. The photopolymer layer thickness and its optical properties is take into consideration. The experimental testing of the calculation method is fulfill by using the physical model of the photopolymer layers. The model photopolymer layers has the optical properties, corresponding to this in the polymer layers. The information about the light scattering along the layer thickness was registered on the sensitive film. It was found a good correlation between the different methods of determination the printing element profile. The result of this work is that it is possible to determine the profile as well as to optimize the structure of photopolymer plate according to a desire profile.
