The Method of Determination of the Profile Photopolymer Printing Elements and the Optimization a Photopolymer Structure

摘要

The profile of the printing elements is the most important qualitycharacteristic of the photopolymer plate. In this work the profile wasdetermined by using the Fourier transform analysis. The photopolymerplate is considered as multi layers system. The exposing light scatteringwas evaluated by calculating of the transform characteristics of the systemfor making the printing plate. The photopolymer layer thickness andits optical properties is take into consideration. The experimental testingof the calculation method is fulfil by using the physical model of thephotopolymer layers. The model photopolymer layers has the opticalproperties, corresponding to this in the polymer layers. The informationabout the light scattering along the layer thickness was registered on thesensitive film. It was found a good correlation between the differentmethods of determination the printing element profile. The result of thiswork is that it is possible to determine the profile as well as to optimizethe structure of photopolymer plate according to a desire profile.
