Nautilus GB Ltd | Date: 2016-04-13

A substrate, comprises a plurality of substantially equally spaced embossed grooves and a line of material provided in the vicinity of at least one of the embossed grooves. In a first region of the substrate, the line of material has a fixed positional relationship with at least one of the embossed grooves to provide a first visual effect when the substrate is viewed from a first angle, and a second visual effect when the substrate viewed from a second angle. In a second region of the substrate, there is a deviation in the fixed positional relationship between the line of material and the at least one of the plurality of embossed grooves to provide a third visual effect in the second region when the substrate is viewed from the first angle and a fourth visual effect when the substrate is viewed from the second angle.

According to the present invention, there is provided a substrate comprising: a plurality of embossed grooves extending in a substantially parallel manner, there being a pitch for the spacing between the embossed grooves; a plurality of lines of deposited material provided in the vicinity of the embossed grooves, and extending in a substantially parallel manner, there being a pitch for the spacing between lines of deposited material, the deposited material having a different colour to the substrate; in a background region of the substrate to be presented to a viewer of the substrate, there being a fixed positional relationship between the substantially parallel embossed grooves and the substantially parallel lines of deposited material, such that the region presents a first background to a viewer of the substrate when viewed from a first angle, and such that the region presents a second background to a viewer of the substrate when viewed from a second angle, the first and second angles being defined as angles on either side of a perpendicular to that substrate; and in an image region of the substrate to be presented to a viewer of the substrate, there being one or more deviations from the fixed positional relationship to provide a first image feature against the first background when viewed from the first angle, and a second image feature against the second background when viewed from the second angle, and wherein, if the one or more deviations are in the line or lines of deposited material, each of the one or more deviations is lesser in extent than the pitch of the embossed grooves, and for a majority of that region of the substrate; or if the one or more deviations are in the embossed groove or grooves, each of the one or more deviations is lesser in extent than the pitch of lines of deposited material for a majority of that region.
