Abstract (en)
[origin: WO2006013352A1] A pub is recognition security device comprises a planar substrate providing first and second areas. Each area has a printed, raised line structure of spaced apart lines with a background filling the spaces between the lines. The visual colour appearance of the lines (1a, 2a) is different to that of the background (1b, 2b) and the visual colour appearances of the respective backgrounds (1b, 2b) and/or of the respective line structures of the two areas differ from one another. When viewed by an observer perpendicularly to the substrate, the resultant visual colour appearances of the two areas is a combination of that of the respective background and raised line structure of each area and appear substantially the same. When viewed by an observer at an oblique angle, the resultant visual colour appearances of the two areas differ from one another due to at least part of the backgrounds being obscured by the corresponding raised line structures, the change in the resultant visual colour appearances of the two areas being indicative of the device authenticity.
