摘要： An optically variable device is disclosed having a substrate with an array of pyramidal structures formed upon it or within it. The structures are coated with an optically variable color-shifting coating. Each of the structures form a pyramidal-like having at least three slanted faces and wherein one or more colors seen when viewing the pyramids vary as substrate is rotated at least 30 degrees about an axis orthogonal to the substrate. In order to see a color shift the device is rotated around the surface normal of the substrate, while keeping the angle of incidence to the light source the same, and keeping the viewing angle the same. Various forms of pyramids may be used, however pyramids with planar faces are most suitable.

摘要： An optically variable device is disclosed having a substrate with an array of pyramidal structures formed upon it or within it. The structures are preferably formed by printing pyramids with an optically variable color-shifting ink using an Intaglio-like printing process. Alternatively the structure can be formed by embossing a layer of ink with positive pyramids so as to yield an array of positive embossed pyramids. Each of the structures form a pyramidal-like having at least three slanted faces and wherein one or more than one color is seen when viewing the pyramids vary as substrate is rotated at least 30 degrees about an axis orthogonal to the substrate. In order to see a color shift the device is rotated around the surface normal of the substrate, while keeping the angle of incidence to the light source the same, and keeping the viewing angle the same. Various forms of pyramids may be used, however pyramids with planar faces are most suitable.

摘要： A magnetic field is applied to planarize magnetic pigment flakes relative to a surface. Pigment flakes, such as optically variable pigment flakes, are used in a variety of paints, inks, extrusions, powder coatings, and other forms for decorative and security applications. In many applications pigment flakes tend to align parallel to each other and to the surface to which they are applied. If the pigment flakes include a suitable magnetic structure, a magnetic field can be applied to subsequently align the flakes or enhance the alignment of the flakes in the plane of the substrate if the carrier that the flakes are dispersed in is still fluid. In some printing operations, pigment flakes that are applied parallel to the substrate are pulled out of plane when the print screen or printing die is lifted off the substrate. Application of a magnetic field can re-align pigment flakes to the plane of the substrate, enhancing the visual quality of the printed image, especially with optically variable pigments.
摘要翻译： 施加磁场以使磁性颜料片相对于表面平坦化。 用于各种油漆，油墨，挤出物，粉末涂料和其它用于装饰和安全应用的形式的颜料薄片，例如光学可变的颜料薄片。 在许多应用中，颜料薄片倾向于彼此平行并且与它们所施加的表面对齐。 如果颜料薄片包括合适的磁性结构，则如果薄片分散在其中的载体仍然是流体，则可以施加磁场以随后对准薄片或增强薄片在基材平面中的对准。 在一些印刷操作中，当印刷屏幕或印刷模具从衬底上提起时，平行于衬底施加的颜料薄片被拉出平面。 磁场的应用可以将颜料薄片重新调整到基底的平面，增强印刷图像的视觉质量，特别是使用光学可变颜料。

摘要： Pigment flakes are blended together wherein some are magnetically alignable and exhibit a color shift from a first color to a second color with a change in viewing angle; and some are pigment flakes which exhibit a color shift from the first color to a third color or vice versa with a change in viewing angle, wherein the first, second and third colors are three different colors. The flakes are coated upon a substrate and magnetically alignable flakes are magnetically aligned. The non-magnetically alignable flakes are not aligned by the magnetic field and lie flat upon the substrate they are coated on. By judiciously selecting the angle upon which the magnetic flakes are oriented, an effect is created whereby an observer sees a color shift from a first color to a second or a first color to a third, when orienting the substrate by tilting it at different particular angles. The coated substrate can be used in security applications such as on currency or secure instruments.

摘要： A scanning laser having a wavelength compatible with a coating binder so as to cure it as the laser scans and irradiates the coating on a moving web. A system and method for curing flakes by providing a scanning laser which scans across a moving coated substrate in a magnetic field allows images to be formed as magnetically aligned flakes are cured into a fixed position. The images have regions of cured aligned flakes. The scanning laser cures the magnetically aligned flakes within it region it irradiates. Alternatively an array of lasers can be used wherein individual lasers can be switched on and off to fix irradiated coating as a moving web is moved at a high speed.

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.
