SECURITY STRIP AND SECURITY PAPER COMPRISING SAME

摘要

A security strip (1) consisting of sectors in which the background is non-continuous so that it is more difficult to duplicate by optical means than a continuous background, thereby making the strip harder to counterfeit. The non-continuous background consists of a dot pattern (2) printed using conventional printing techniques on an area (3) in which the repeated absence of dots defines a symbol (4), wherein the dots (2) of the pattern are geometrically and dimensionally distributed in such a way that they cannot be seen by the naked eye because the gap (3) between the dots cannot be discerned and the background appears to be continuous.
