PROVISION OF FRAMES OR BORDERS AROUND PIGMENT FLAKES FOR COVERT SECURITY APPLICATIONS
Opaque flakes, such as pigment or bright flakes used in paints and inks, have a selected shape and/or other indicia to provide a covert security feature to an object. Shaped opaque covert flakes are not readily detectable by causal observation, but in some embodiments are easily seen at 50X magnification. In manufacturing the flakes a sheet of embossed frames are provided having embossed symbols or indicia within. Upon removing a coating from the embossed sheet the coating material tends to break along frame lines or grooves and the resulting flakes are substantially uniform in size. In order to have the flakes break along frame lines or grooves more readily than along the embossing or grooves defining indicia within a frame, the frames are provided with a deeper groove than indicia grooves. As well a groove having a different shaped profile conducive to breakage can be used for the frame grooves whereas a groove having a profile less conducive to breakage can be used to form the indicia grooves. We have found that the flakes can be further protected from breakage by coating them in a protective coating. This coating may have other features which makes the logo more visible.

The area density of the ink in a line in the first group of wider lines is greater than the area density of a line in the second group of narrower lines. A surprising effect of this image is that particles or flakes in the ink are field aligned so as to produce a visible kinematic dynamic effect visible in the first region and not visible in the second region when the image is tilted or rotated.
A printing apparatus includes a magnetic rotatable roller with a smooth even outer surface for aligning magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as bank notes. Magnetic flakes in the ink are aligned using magnetic portions of the roller, that can be formed by permanent magnets embedded in a non-magnetic roller body, or selectively magnetized portions of a flexible magnetic cover of the roller. In some embodiments, the roller is assembled for a plurality of interchangeable sections, which can include spinning magnets. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.

This invention discloses a magnet for use as a printing plate or printing head that is used for aligning flakes or particles in a paint or ink. A composite sheet or block of magnetizable material is selectively magnetized so that a magnet is formed within the sheet or block that has a shape of a predetermined image, logo, or indica. Dies are used to magnetize the magnetizable material and preferably the does contact the material to be magnetized. A pre-magnetized sheet such as a refrigerator magnet may be re-magnetized differently so that a magnetic image is encoded therein for use as a printing plate. Preferably the printing plate is flexible so that it can be formed to a curved surface of a cylinder or drum for printing. Conveniently these flexible magnets can be changed for other deisgins and placed on the same drum for use in printing.

PATTERNED OPTICAL STRUCTURES WITH ENHANCED SECURITY FEATURE
A security image and method for forming said image is disclosed wherein an image having a layer with a hologram therein has an additional layer of magnetically aligned flakes together forming an image that is difficult to counterfeit and is highly attractive. Preferably windows of an opaque layer provide additional means of encoding or forming the image.
A two-step method of making of a security printed image is disclosed and includes coating of the surface of a substrate with a predetermined image shape with an ink containing flaked magnetic pigment in a predetermined concentration, exposing a wet printed image to a magnetic field to align magnetic particles in a predetermined manner, allowing the ink to cure, and coating the substrate with a second printed image on the top of the first image. The second printed image with the same or different image shape is printed with another ink containing clear or dyed ink vehicle mixed with flaked magnetic pigment in a low concentration, exposed to the magnetic field of the same or different configuration as the first printed image and cured until the ink is dry.
Opaque flakes, such as pigment or bright flake used in paints and inks, have a selected shape and/or other indicia to provide a covert security feature to an object. In some embodiments the composition includes base pigment, and the opaque covert flakes match the visual characteristics of the base pigment. In another embodiment, opaque covert flakes are mixed in the carrier with base pigment at a concentration sufficient to avoid changing the appearance of the composition. In another embodiment, opaque covert flakes are mixed in a clear or tinted varnish base that can be applied over an existing security feature. Shaped opaque covert flakes are not readily detectable by causal observation, but in some embodiments are easily seen at 50X magnification. In manufacturing the flakes a sheet of embossed frames are provided having symbols or indicia within; upon removing a coating from the sheet the coating material tends to break along frame lines and the resulting flakes are substantially uniform in size.
A multilayer thin film filter is disclosed an organic dielectric layer serving as a spacer layer in a Fabry-Perot structure. The dielectric has embossed regions of varying thicknesses wherein the thickness within a region is substantially uniform. Each different region of a different thickness produces a different color (shift). The size of one of the embossed adjacent regions is such that the color of said one region is uniform and cannot be seen by a human eye as different in color from the uniform color of an adjacent region thereto, and wherein the color within a region can be seen with magnification of at least 10:1. This serves as a covert color coding system useful as a security device.

A printed image is disclosed wherein the image may be in the form of an array of magnetically aligned platelets or flakes that may by uniform in shape and size and wherein the flakes are arranged in a particularly manner to form optically illusive images useful as security devices, or useful in beam steering applications. In one embodiment of this invention printed array is disclosed a plurality of concentric rings of magnetically aligned platelets disposed upon a substrate in the form of a Fresnel structure, preferably a Fresnel reflector. Advantageously, since the magnetic field can be controlled with respect to strength and direction, one can easily design a field that will correct for spherical aberration that would otherwise be present in a typical Fresnel reflector. In other embodiments of the invention optically illusive images of funnels, domes and cones are printed.

A method and image made by the method is disclosed wherein non-spherical magnetically alignable optical pigment flakes in transparent carrier are applied to a substrate and are aligned by applying a magnetic field to the substrate. The pigment flakes align a long magnetic field lines and a tool for impressing or scribing the flakes is applied to a sub- region of the substrate to realign or remove flakes from a desired region. For example a scribing tool can be used to scribe a signature or other marks within the magnetically aligned flakes. The flakes are then cured and the image is preserved which has optical and tactile features.

KINEMATIC IMAGES FORMED BY ORIENTING ALIGNABLE FLAKES
The invention relates to images formed in a painting or printing process; the images include pigment flakes aligned to obtain an illusive optical effect. A non- rectangular closed region of a substrate is coated with a coating containing aligned pigment flakes, wherein said flakes are aligned in an arching pattern so as to produce a kinematic object therewithin. The kinematic object appears to move across the closed region as the image is tilted or the position of the light source upon the image is varied; the non-rectangular closed region has a curved border so that the area of the kinematic object changes as it appears to move across the region or the kinematic object appears to move horizontally and vertically simultaneously as the kinematic object appears to move.

ALIGNMENT OF PASTE-LIKE INK HAVING MAGNETIC PARTICLES THEREIN, AND THE PRINTING OF OPTICAL EFFECTS
A method and apparatus is provided for printing using paste like inks such as those used in intaglio printing, wherein the inks include specialty flakes such as thin film optically variable flakes, or diffractive flakes. The invention discloses an apparatus having an energy source such as a heat source for temporarily lessening the viscosity of the ink during alignment of the flakes within the ink.
Covert flakes having one or more symbols and/or a selected shape are used in a composition, such as ink or paint, to provide a covert security feature to an object. In some embodiments the composition includes base pigment, and the covert flakes are covert pigment flakes that match the visual characteristics of the base pigment. In other embodiments, clear or opaque covert flakes are mixed in the carrier with base pigment. In other embodiments, clear or opaque covert flakes are mixed in a varnish base to provide a clear composition that can be applied over an existing security feature or elsewhere. The composition is used to print a field on the object, such as a stock certificate or bank note, for example. The covert flakes are not readily detectable by causal observation under visible light. In one embodiment, illuminating the covert security feature with ultraviolet light causes a covert flake to fluoresce and allows the observer to identify the location of the covert flake so that cover indicia may be observed. In a particular embodiment, a covert flake having one or more symbols is located using non-visible radiation, and then observed under visible light to read the symbol(s) on the covert flake.

Protocol analyzers systems and methods coordinate the capture of network data of interest across multiple chassis. Each chassis has individual blades with accompanying ports and is serially connected to other chassis in the system. Selected ports from each chassis are configured in domains that can be spread across the serially connected chassis and used in coordination to capture network data of interest. A serial protocol containing control signals is used to transmit run, stop, and trigger data between the serially connected chassis and thereby coordinate the activity of ports within each domain. Through the use of the serial protocol the number of wires connecting adjacent chassis is minimized and each of the blades in the multi~chassis systems can be synchronously started, stopped, and triggered at the same time to synchronously capture the network data of interest.
