摘要： 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 100null magnification.

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： Apparatus and related methods align 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 magnets in a linear printing operation. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.
