The properties of UHF RFID reader-tag system in logistic applications were analysed. The effects of metalized packaging and water content on readability of data on RFID tags were analysed. Tags with different antenna design were applied. The so-called fading effect was analysed in rooms with different reflections of electromagnetic waves. The results were published as reviewed contributions on international conferences. The complete research article is currently under reviewing process.

Electrical properties of multilayered structures depend on temperature and heating time of conductive layers and on curing dose of dielectric layers. Structural changes of layers printed with Ag-based ink increases conductivity with drying time and temperature. Similarly, the dielectric constant of dielectric layers depends on curing dose. When microstructure stabilizes, electrical properties become constant. Some results are published, one article was submitted, others are in manuscript.

Fast and relevant in-line control of printed electronic structures based on image analysis was introduced. For automatic and evaluation different routines to capture the sample were used, developed, modified or upgraded. The possibilities for using in-line control methods for evaluation of printed passive RFID antenna tags were analysed. The method was shown to be potentially useful for new standard method for printed electronics in graphic technology.

The properties of screen-printed inks with flaky-shaped particles were evaluated. The mesh geometry and size of particles were varied together with the influence of substrate. The orientation of flakes and layer microstructure was evaluated by optical, spectroscopic and microscopic methods. The influence of wet on wet printing on layer microstructure was analysed. The study is important to understand the conductivity of lines printed with silver-based ink in relation on printing parameters.

Photobiological safety of laboratory UV-curing equipment was analysed according to the new Regulation on the protection of workers from risks related to exposure to artificial optical radiation sources. Spectral irradiances on working positions were measured. Exposure levels for skin and eyes were calculated. The protection ability of the lab coat textile, protective goggles and gloves were analysed. This research is important for safely working with UV-curable printing inks.
