protection of printed documents

Метод побудови анімованих захисних елементів для друкованих та електронних відбитків

The developed is the way of protection the printed impression by creating animated objects. The method of protection is a static image that created with “animation”. Movement is provided through the plastic sheet, which is displaced in a horizontal direction. The method can be used for both electronic and printed documents. The choice line thickness and gaps for high-quality playback means printing equipment.

Програма перетворення растрових контурних зображень на основі фрактальних сіток

The software for transforming raster images to contour curves fractal Hilbert. The
program can be used to protect and convert images in printed documents. The output format
is a vector image.

Development method of protecting images with amplitude-modulated screening using ateb-functions

Proposed method of protection can be used for protection of printed documents and it is not expensive. The theory of Ateb-functions, which is && of classic trigonometry, was used as a mathematical apparatus to develop method of rasterization. A rasterization with  amplitude-modulated method for offset printing is developed
