METHOD OF MANUFACTURING PROTECTIVE ELEMENT FOR SECURED DOCUMENT Russian patent published in 2014 - IPC B42D25/351 

FIELD: printing.

SUBSTANCE: invention relates to the field of protective elements for valuable documents or security documents. The method of manufacturing the protective element for a security document and the protective element comprises a substrate defining the first and second opposite sides, and in the substrate a translucent area is formed by applying material which increases the transparency of the substrate, and for forming the said translucent area the method comprises the following steps: the first step - applying the material for obtaining the impermeable substrate in the first area of the first side, and the first area surrounds the second area of the first side which does not comprise the said material creating impermeability, at that the material creating impenetrability prevents impregnating of the substrate in the first area by the material increasing the transparency. The second step - the application of the material increasing the transparency on at least the second area so that to impregnate the substrate and to make it transparent in this area, and the first area and the second area form the first pattern and the second pattern, respectively, which form an image that is viewed from two sides of the substrate.

EFFECT: invention provides creation of the simple and inexpensive protective element that ensures high degree of protection against forgery.
