Documents (such as but not limited to lottery tickets), systems for manufacturing documents (such as but not limited to lottery tickets), and methods for manufacturing documents (such as but not limited to lottery tickets), wherein the document (such as an instant lottery ticket) that has a consistent overprint that covers both a SOC area and a display area of the document, and that thus provides a consistent application and appearance of the overprint despite the differences in the ink chemistry and texture of the SOC area and the display area surfaces of the document that underly the overprint. The overprint can include artwork including one or more images (such as but not limited to patterns).

The invention relates to a security foil element (12) for securing valuable objects (10), having a foil carrier (20) and a selection layer (24) applied to at least some portions of the foil carrier. The foil carrier (20) is formed from an extrudable plastic and in its volume is mixed with a machine-readable luminescent marker (22), which is used to emit luminescent radiation having a first wavelength and a second, different, wavelength (32, 34), each in the infrared spectral range. The selection layer (24) is designed to selectively spectrally inhibit the transmission of IR radiation, wherein the inhibiting effect on transmission differs for the first and second wavelengths (32, 34) by at least 10 percentage points.

A method for detecting a component including a concealed pattern includes: detecting infrared electromagnetic radiation reflected or emitted by a component including a first pattern, the component including: a substrate; the first pattern disposed over at least a portion of the substrate; an optional primer layer disposed between at least a portion of the substrate and at least a portion of the first pattern; and a first visibly opaque layer including an infrared transparent pigment, the first visibly opaque layer disposed over at least a portion of the first pattern; and comparing the reflectivity and/or absorbance of infrared electromagnetic radiation by the first pattern at one wavelength to the reflectivity and/or absorbance by the primer layer and/or the substrate at the same wavelength.
