Sarapulova O. O. (Natsionalnyi tekhnichnyi universytet Ukrainy «Kyivskyi politekhnichnyi instytut» (Kyiv, Ukraina) The influence of the parameters of a printing plate on the luminescent properties of nanophotonic printed coverings. — 2014. — № 1(43). — pp. 97–106.
There is investigated the influence of the parameters of a printing plate (for screen and pad printing on features of printed application of coatings with nanophotonic components and on parameters of the photoluminescence of obtained printed coverings in order to produce nanophotonic elements for security printing and/or smart packaging. To determine the dependence of luminescence intensity on the thickness of solid coating there was carried out the formation of nanophotonic solid surfaces by means of screen printing with different layer thickness on the polypropylene film. The obtained analytical dependencies were used to confirm the explanation of the processes that occur during the fabrication of nanophotonic coverings by pad printing with photopolymer and metal printing plates. As a result of experimental studies, it was determined that the different character of the dependency of integrated luminescence intensity of nanophotonic elements from the percentage of a pad is explained by the use of different types of pad printing plates, where the size of raster points remains constant in one case, and changes in the other case, while the depth of the printing elements accordingly changes or remains constant. There was shown that consideration of the influence of investigated factors on changes of photoluminescent properties of nanophotonic printed surfaces that should be allows to obtain nanophotonic areas with predetermined photoluminescent properties.
