Printed image

A printed image comprising at least two printed area units on a substrate, wherein each of the area units comprises flake-form effect pigments and a binder, a first printed area unit comprising solidified area of a first printing ink comprising a first flake-form effect pigment, said first flake-form effect pigment being based on coated support flakes and having an outermost layer consisting of a non-metallic, inorganic material, and a second printed area unit comprising a solidified area of a second printing ink comprising a second flake-form effect pigment, which is based on coated support flakes and has an outermost layer comprising an organic surface modifier, and wherein said first and second printed area units are visible simultaneously to the naked eye and optically distinguishable from one another when viewing the substrate on a surface carrying the printed image at any viewing angle and have different flop indicies from one another, said first flake-form effect pigments are arranged in random distribution in the first printed area unit and said second flake-form effect pigments are aligned parallel to the substrate at the surface of the second printed area unit.
