Abstract
The invention relates to improvements in security features which comprise at least one printed image and, in particular, to such security features which provide an improvement in the resolution of printed images forming security features using inks, pigments or printing processes which do not lend themselves to the production of sharply defined or high resolution images. The security feature comprises an opaque first image and a second image at least partially overlying the first image, the second image being a printed image which has a lower visual resolution than the first image. The formation of the second image is such that, when the security feature is viewed in transmitted and/or reflected light, only the shape of the first image is readily discernable.
