    Abstract: Disclosed is an item, for example a document, including a substrate having thereon a multiplicity of separate printed markings, wherein the printed markings include both conductive printed markings and substantially non-conductive printed markings. The different conductive and substantially non-conductive regions on the substrate can be detected, for example by measuring the resistance or current of each printed marking. The pattern of different conductive and substantially non-conductive regions can be used as a security pattern of authenticity that cannot be replicated by standard office equipment, and/or can be used to encrypt information in binary code form in the item. A system for forming and detecting the different printed markings is also described.

    Abstract: A method for determining whether an item has been exposed to an environmental condition during a monitoring period. The method includes placing a sensor at least in proximity to the item at the beginning of the monitoring period so that the sensor will be exposed to a level of an environmental condition that can be correlated to an exposure level of the item to the environmental condition; reading the sensor; and determining from reading the sensor whether the item has been exposed to the environmental condition. The sensor includes a detecting material comprising a photochromic or photothermochromic material, the detecting material selected so that upon exposure to the environmental condition the detecting material exhibits a detectable color change.

    Abstract translation: 一种用于在监视期间确定物品是否已经暴露于环境条件的方法。 该方法包括在监测周期开始时将传感器至少放置在物品附近，使得传感器将暴露于可以将物品的曝光水平与环境条件相关联的环境条件的水平; 读传感器; 并且从读取传感器确定物品是否已经暴露于环境条件。 传感器包括检测材料，其包括光致变色或光致变色材料，所述检测材料被选择为使得当暴露于环境条件时，检测材料表现出可检测的颜色变化。

    Abstract: An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.

    Abstract: A reimageable printing member such as for use in flexography, includes a layer having a multiplicity of holes, wherein the holes include therein a dimension change material and a printing material upon the dimension change material. Thus, the holes house vertically expandable units, the top portion of which is capable of protruding out of an opening of the hole at a top surface of the layer. Each of the holes may be individually addressed to provide a stimulus that initiates a change in dimension in the dimension change material. In this manner, selected ones of the units may be made to print a corresponding portion of an image on an image receiving substrate brought into contact with the printing member.

    Abstract: An ink set includes a plurality of inks, at least one ink but less than all inks of the ink set including an ink vehicle, colorant and fluorescence agent and remaining additional inks including an ink vehicle, colorant and free of fluorescence agent. At least a first ink grouping and a second ink grouping of the ink set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first ink grouping and the second ink grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first ink grouping as compared to the second ink grouping.
