    摘要： A method of planarizing a plurality of orientable non-spherical flakes supported by a longitudinal web is disclosed. A web supporting a coating of field orientable non-spherical flakes is placed between magnets so that the fields from the magnets traverse the web. First and third magnets are provided on one side of a feedpath and a second magnet is provided between the first and third magnets on the other side of the feedpath. The first and third magnets have a same polarity and the second magnet has a complementary polarity to the first and third magnets, so that a first magnetic field spanning the feedpath is present between the first and second magnets and second magnetic field spanning the feedpath is present between the second and third magnets, wherein the magnets are positioned so that a plurality of non-spherical field orientable flakes moving along the feedpath experience a first rotation as they pass the second magnet during relative movement between the web and the magnets; The web is then moved through the fields passing the magnets and the coating is subsequently cured.

    摘要： 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.

    摘要： A method of forming pigment flakes includes using a deposition substrate having a plurality of regions; some of the regions are raised or lowered so that there is a level difference between each two adjacent regions. A coating deposited onto this substrate breaks along region borders when it is separated from the substrate. In one embodiment, the substrate includes first and second regions, wherein each of the first regions is in an abutting relationship with at least one of the second regions. All the first regions are at a first level and all the second regions are at a second level, and the difference between the first and second levels is greater than a predetermined value. The first and second regions are preferably square-shaped regions for manufacturing square flakes with practically no debris.
