A security element, including: a substrate having a first structured major surface and a second structured major surface; and a first metal layer coated on the first structured major surface, wherein the transparency of the first metal layer is between 10% and 90%; and a second metal layer coated on the second structured major surface.

A method of fabricating an identification card for an individual is provided. The method includes the steps of storing items of information associated with the individual on a memory and providing the identification card with inner and outer layers laminated to each other. The memory is operatively connected to a printer and at least one selected item of information is on a first portion of the inner layer of the tag. A second portion of the inner layer of the tag is removed and a first portion of the outer layer is folded over and affixed to the first portion of the inner layer such that the first portion of the inner layer is captured between the first portion of the outer layer and a second portion of the outer layer.

A method when expressing gradation for a color image including binarizing tone values of first image data to produce second image data including pixels each having colors with respective binarized tone values, classifying pixels of the first image data into a plurality of first pixel groups and specifying a pixel where a color centroid is positioned for each color in each first pixel group, classifying pixels of the second image data into second pixel groups PXG2 corresponding to the first pixel groups and calculating the number of light pixels for each color in each second pixel group, producing third image data from the second image data, information related to the color centroid, and information related to the number of light pixels, and producing fourth image data by changing the position of a light pixel with the position of a dark pixel in the third image data.

A method of processing sheet stock in the creation of plastic cards, such as gift cards or credit cards that include special effects and/or security measures. A card formed by such methods is also disclosed. The method provides for two or more dissimilar materials to be bonded together while maintaining the integrity of the card and as any graphics, security features, and/or special effects provided thereon. Thermoset and thermobond adhesive layers are placed between a first material layer and a second material layer of the sheet stock. The thermoset and thermobond adhesive layers allow the first and second material layers to move independently and to expand and contract at different rates relative to each other. The adhesive layers enable the sheet stock to be rolled up for shipping or storage and further enable the end product produced therefrom to have a planar profile.

An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.
