Description

Motion image formed by positioning a calibratable sheet

The present invention relates generally to optically variable pigments, films, inks, paints, components, and images, and more particularly to images having calibrated or positioned pigment flakes, for example, in a paint or printing process. Get an illusory optical effect. The invention is particularly applicable to calibrating magnetically calibratable pigment flakes and also to calibrating non-magnetic dielectric or semiconductor flakes in an electric field.

Optically variable components are used in a wide range of applications, both decorative and practical. Optically variable elements can be fabricated in a variety of ways to achieve various effects. Examples of optically variable elements include holograms printed on credit cards and real software documents, color drift images printed on banknotes, and surface appearance of objects such as motorcycle helmets and wheel covers.

The optically variable element can be made as a film or foil film that is pressed, printed, adhered, or otherwise attached to an object, or can be made using optically variable pigments. One type of optically variable pigment is commonly referred to as a color changing pigment because the surface color of an image suitably printed using such pigments changes when tilted at an angle of view and/or illumination. A common example is a "20" printed with a color-changing pigment on the lower right corner of a US $20 banknote as a security element.

Some security elements are hidden, while others are expected to be noticed. The present invention relates to features that are expected to be noticed, however, sheets having concealed features, such as indicia, can be used therein. In addition, sheets having grid and holographic features can be used. However, some optically variable elements that are expected to be noticed are not widely known because the optically variable aspect of the element is not sufficiently dynamic. For example, color changes in images printed with color-changing pigments may be unnoticed under a uniform fluorescent ceiling light, but are more noticeable under direct sunlight or single-point illumination. It allows the counterfeiter to more easily circulate counterfeit notes that do not have optically variable features, as the recipient may not be aware of the optically variable features, or because in some cases the counterfeit notes and the real notes generally look the same.

The optically variable element can also be made from a magnetic pigment which is calibrated using a magnetic field after application of the pigment, typically in a carrier such as an ink vehicle or a paint carrier, to a surface. However, paints using magnetic pigments are mostly used for decorative purposes. For example, the use of magnetic pigments to produce painted wheel covers having decorative features that behave in a three-dimensional shape has been described. A pattern is formed on the painted product by applying a magnetic field to the product while the paint medium is still in a liquid state. The paint medium has dispersed magnetic aspheric particles that are aligned along the magnetic field lines. The field has two zones. The first zone contains a plurality of magnetic lines of force that are positioned parallel to the surface and configured in a shape of a desired pattern. The second zone contains lines that are not parallel to the surface of the painted product and that are disposed around the pattern. To form the pattern, a permanent magnet having a shape corresponding to the shape of the desired pattern, or an electromagnet placed under the painted product to position the non-spherical magnetic particles dispersed in the paint in a magnetic field while the paint is still wet . When the paint dries, when the light incident on the paint layer is affected differently by the positioned magnetic particles, a pattern can be seen on the surface of the painted product.

Similarly, a method for producing a pattern of one of the sheet magnetic particles in a fluoropolymer matrix has been described. After coating the product with a composition in a liquid form, a magnet having the desired shape is placed on the bottom surface of the substrate. A magnetic sheet dispersed in a liquid organic medium positions itself in parallel with the magnetic field lines, tilting from the initial flat position. The tilt changes from an initial surface perpendicular to a substrate to an initial position, the initial positioning comprising a sheet substantially parallel to the surface of the product. The flatly positioned sheet reflects incident light back to the viewer, while the repositioned sheet does not provide the appearance of a three dimensional pattern in the coating.

There is a need to create more flexible optically variable security features in financial literature and other products and to provide features that make it difficult for counterfeiters to replicate.

There is also a need to create features that increase the realism of printed images made from ink and paint having calibratable sheets therein, particularly printed images of objects and, more specifically, recognizable three-dimensional objects.

In the patent application PCT/US2003/020665, the inventor of the present application has described an embodiment of one of the inventions commonly referred to as "rolling bars" and "positive and reverse", which will provide dynamic features (ie provide motion) The feature of optical phantoms is provided to images containing magnetically calibratable pigment flakes in which the flakes are calibrated in a particular manner. Despite its significant advancement in the field of pigment sheet calibration, and more generally with anti-counterfeiting coatings, the inventors have discovered novel and interesting applications of previously unimplemented scroll bars and other rolling objects, such as generation by calibratability The rolling hemisphere of the real three-dimensional image formed by the pigment flakes. The rolling hemisphere appears to move in any direction on an x-y plane depending on the angle of the tilted image or the angle of change of the light source on the image.

Although the scroll bar described in the previously mentioned PCT patent application provides a phantom that moves across one of a rectangular image, the invention has limitations. Observable is a single dynamic feature. It is also difficult to copy. However, it essentially provides the viewer with the experience of observing a scroll bar of uniform size and intensity that does not change in size and intensity as the scroll bar appears to move along the substrate on a rectangular image separated therefrom.

In the present invention, the inventors have thus discovered that providing one of the shapes for use as a curved identifiable object (specifically, a smoothly curved identifiable object such as a bell, a shield, a container or a soccer ball) The scroll bar of the filler provides a significant effect that exceeds the effect provided by the scroll bar moving back and forth on a rectangular sheet. When the strip provides a true motion shadow to an image of an object, it not only appears to move across the image, but also appears to grow and contract or expand and shorten with the motion in the closed region containing it. In some instances, when the size or area of the strip does not change, for example, where the strip acts as a partial fill in the image between two matching curves that move together and have a space filled by the strip, The scroll bar appears to move across the image while moving up and down. Accordingly, the present invention provides a highly desirable optical effect by using a scroll bar in a closed shape of a non-rectangular outer shape of an object, wherein the area of the scroll bar changes as the strip moves past the image, and or When the light source on the tilted image or image changes, the strip appears to move horizontally and vertically simultaneously. Moreover, if the strip is designed to have a suitable size and radius of curvature, it can be used as a moving, moving, contracting or expanding shadow element in an image to provide a particular sense of reality. It has also been found that when the scroll bar appears to mimic a moving shadow on one of the images of a real object (which can produce a shadow when the light is incident on the object), the scroll bar appears to have the deepest effect. In such important applications, preferably, the radius of curvature of the sheet forming the scroll bar is within a range of values, wherein the image of the real object to be applied exhibits correct bending for authenticity. One object of the present invention is to provide an optical phantom image having a tilted image or a dynamic feature that changes the position of the light source on the image.

The term "rectangular" as used in this specification is defined to mean a quadrilateral having four right angles. Therefore, a non-rectangular object or image does not have four sides and four right angles.

The present invention relates to forming an image of an object, wherein the image of the object includes special effects, such as a scroll bar effect that provides a phantom of the moving shadow when the image of the tilted object or the source of light on the image changes. The "object" in this paper is defined as a tangible and visible entity; an entity that can cast a shadow.

The term "scroll bar" should not be limited to a straight strip, it can also be a curved strip depending on the shape of the field applied.

According to an embodiment of the invention, there is provided a motion image particularly suitable for use as a security feature or a decorative feature, comprising a non-rectangular closed region of an object having a scroll bar therein, wherein the oblique image or image When the position of the light source changes, the scroll bar appears to move over the image, and when the scroll bar moves over the image, the area of the scroll bar changes, or when the scroll bar appears to move, the bar appears as Move horizontally and vertically at the same time.

According to the present invention, there is provided a motion image comprising an image printed on a substrate, the image comprising a plurality of pigment sheets, wherein the sheets exhibit a first arcuate pattern to form a first contrast strip across at least a portion of the image And wherein the sheets exhibit a second arcuate pattern to form a second contrast strip across at least a different portion of the image, and wherein the first and second contrast strips behave when the image is tilted relative to a viewing angle To move in different directions at the same time.

A dynamic image of an object is provided in accordance with the present invention. The image comprises a plurality of field calibration pigment flakes, wherein the object has a recognizable three-dimensional variation shape in a three-dimensional space, and one of the scroll bars is disposed in an outer shape of the object image, so that the image is tilted relative to the viewing angle A varying shadow effect is sometimes provided, and wherein the area of the scroll bar changes as the image is tilted relative to the viewing angle.

In other embodiments of the invention, the radius of curvature of the scroll bar is at least as large as the radius of curvature of one of the curves within the image profile.

In another embodiment, the radius of curvature is sufficient to span the entire image of the three dimensional real object.

I. Introduction

The present invention, in various embodiments thereof, provides a method of locating magnetic sheets in optically variable inks or paints that are suitable for use in a high speed printing process in certain embodiments, wherein other embodiments are more suitable for use in A manual calibration and printing process. Moreover, some embodiments of the present invention require a multi-step printing process in which a magnetic sheet is used to ink a first region of a substrate and expose it to a magnetic field, and wherein after hardening, the same substrate is in the same Or ink is applied to different zones and exposed to a second magnetic field. Typically, particles of optically variable pigment dispersed in a liquid paint or ink vehicle are generally positioned to be parallel to the surface when printed or painted onto a surface. Positioning parallel to the surface provides high reflectivity for the person to illuminate from the coated surface. When the magnetic sheet is in a liquid medium, it can be tilted by applying a magnetic field. The sheets are typically calibrated in this manner such that the longest diagonal of the sheet follows a magnetic field line. Depending on the position and strength of the magnets, the magnetic field lines can penetrate the substrate at different angles to tilt the magnetic sheets to the equal angles. The oblique sheet is different in reflection from the incident light than a sheet parallel to the surface of the printed substrate. Both reflectance and hue can vary. Viewed from a vertical viewing angle, the slanted sheet generally looks darker and has a different color than a sheet that is parallel to the surface.

Positioning magnetic sheets in printed images creates several problems. A variety of modern printing processes are high speed with respect to batch-type processes, which apply a magnet to a static (non-moving) coated article and hold the magnet in place when the paint or ink is dry. In some printing processes, the paper substrate moves at a speed of from 100 meters per minute to 160 meters per minute. The paper sheets are stacked after one printing operation and fed to the other. The ink used in such operations typically dries out within a few milliseconds. The conventional process does not apply to such applications.

I have found a way to obtain an improved optical effect in a paint or printed image by positioning the magnetic sheet perpendicular to the direction of the moving substrate. In other words, the paint or printed liquid paint or ink medium (with discrete sheets on the substrate) moves perpendicular to the magnetic lines of the field to promote repositioning of the sheets. This type of positioning provides significant illusory optical effects in printed images.

For the purposes of this discussion, one type of optical effect will be referred to as a dynamic optical effect. Assuming a fixed illumination source, an unreal dynamic optical effect generally provides a phantom of motion in a printed image when the image is tilted relative to a viewing angle. Another illusory optical effect provides a virtual depth to a printed, two-dimensional image. Some images provide motion and virtual depth. And some images can provide motion illusion or motion in any direction in an x-y plane. Another type of illusory optical effect can convert the appearance of a print field, such as by alternating between bright and dark colors as the image is tilted back and forth. Another type of optical effect is created by creating an image in which one of the features of the image appears to change in size when the image provides a phantom of motion. One form of real animation is provided by providing a change in the size of an object such as a scroll bar (when the bar is moved).

II. Examples of Unreal Images in Printing

Figure 1A is a simplified cross-sectional view of the U.S. Patent Application Serial No. 20040051, the disclosure of which is incorporated herein to Call it a "scroll bar". The images formed from the pigment flakes are calibrated in a particular manner that provides the effect of a scroll bar surrounded by a carrier such as an ink carrier or a paint carrier. These sheets are shown in Figure 2A as short lines in the cross-sectional view. The sheets are magnetic sheets, that is, a pigment sheet that can be calibrated using a magnetic field. It may or may not retain residual magnetization. The drawings are not drawn to scale. A typical sheet can be twenty microns long and has a thickness of about one micron, so these figures are merely illustrative. The image is printed or painted on a substrate 29 such as paper, plastic film, sheet, card stock (card or other surface. For ease of discussion, the term "printing" will generally be used to describe the application of a pigment in a carrier to a Surfaces, which may include other techniques, include techniques that others may call "paint."

In general, a sheet that is viewed perpendicular to the plane of the sheet appears bright, while a sheet that is viewed along the edge of the plane appears dim.

The carrier is typically clear, it is clear or colored, and the sheets are often quite reflective. For example, the carrier can be green and the sheet can comprise a metal layer such as a film made of aluminum, gold, nickel, platinum or a metal alloy, or a foil such as nickel or alloy flakes. Light that passes through the green carrier and reflects away from a metal layer can appear bright green, while in the case of a vertical viewing sheet, the other portions appear dark green or other colors. If the sheets are only foils in a clear carrier, one portion of the image may appear as a bright metallic color while the other portions may appear dark. Alternatively, the foil may be coated with a colored layer, or the sheets may comprise an optical interference structure such as an absorber-spacer-reflector Fabry-Perot type structure. Additionally, a diffractive structure can be formed on the reflective surface to provide a reinforcement and an additional security feature. The diffractive structure can have a simple linear grid formed in the reflective surface, or can have a more complex predetermined pattern that is discernible only when zoomed in, and has an overall effect when viewed. By providing a diffractive reflective layer, a viewer can see a color change or brightness change by simply rotating a thin layer, banknote or structure having the diffractive flakes.

A method of manufacturing a diffractive sheet is described in detail in U.S. Patent No. 6,692,830. U.S. Patent Application No. 20030190473 describes the manufacture of colored diffractive sheets. Producing a magnetically diffractive sheet is similar to producing a diffractive sheet, however one of the layers needs to be magnetic. In fact, the magnetic layer can be masked by sandwiching the magnetic layer between the aluminum layers; in this way, the magnetic layer does not substantially affect the optical design of the sheet; or the metal layer can be in a thin film interference optics The design acts as an absorber, dielectric or reflector at the same time to act as an optical active.

Figure 2A is a simplified cross-sectional view of a printed image 42 of a dynamic optical "roller bar" as shown in U.S. Patent Application Serial No. 20040051, filed on Mar. The image includes a pigment flake 26 surrounded by a transparent carrier 28 printed on a substrate 29. The pigment flakes are calibrated in a curved manner. Because of the presence of the flip-flop, the light from the surface of the pigment flakes is reflected off the area of the viewer's scrollbar, which is brighter than the area that does not directly reflect the light to the viewer. When the image is tilted relative to a viewing angle (assuming one (or more) of fixed illumination sources), the image provides one (or more) bright bands or strips that appear to move across the image ("scroll").

1A is a simplified plan view of a scroll bar image 42 at a first selected viewing angle. A bright bar 44 is present in a first of the two contrast fields 46 and 48. Figure 1B is a simplified plan view of one of the scroll bar images at a second selected viewing angle. The bright strip 44' appears to "move" to one of the second portions of the image, and the dimensions of the contrast fields 46', 48' have changed. The calibration of the pigment flakes produces a phantom, that is, when the image is tilted (under a fixed viewing angle and fixed illumination), a "rolling" down image. Tilting the image in the other direction causes the strip to appear to scroll in the opposite direction (upward).

The strip also exhibits depth, even if it is printed on a flat surface. The virtual depth may appear to be much larger than the physical thickness of the printed image. The obliquely reflected light of the sheet in the selected pattern provides a phantom of depth or what is commonly referred to as "3D." A three-dimensional effect can be obtained by placing a shaped magnet on a paper or other substrate in which the magnetic pigment flakes are printed on a substrate in a liquid carrier. The sheets are calibrated along the magnetic field lines and solidify the carrier (eg, dried or hardened) to produce a 3D image. When tilting an image, it often appears to move, thus forming a dynamic 3D image.

While the single rectangular scroll bar disclosed in U.S. Patent Application No. 20040051297 has an interesting appealing effect, in this application, providing a moving rectangle on a larger rectangular background appears to be somewhat limited.

Figure 3A is a simplified cross-section of an image of a scroll bar type used to form a semi-circular positioning of a sheet in paint or ink. As illustrated, a thin permanent magnet 106 is magnetized via its thin portion. The magnet has a circular magnetic wire 108 on its end. A substrate 29 having printed magnetic sheets dispersed in a fluid carrier is moved from the viewer along the magnet into the paper. The sheet 26 is inclined in the direction of the magnet wire 108 and forms a semicircular pattern on the magnet.

Figure 3B is a simplified perspective view of one of the devices of Figure 7A. The substrate 29 is moved across the magnet 106 in the direction indicated by the arrow. The image 110 forms a scroll bar feature 114 that appears to move up and down as the image is tilted or the angle of view changes. The sheet 26 is tilted with respect to the magnetic field lines in the figure. The image is typically very thin and the sheet may not form the illustrated peak shape, but is generally calibrated along the magnetic field lines to provide the desired arcuate reflection characteristics to produce a scroll bar effect. When the image is tilted by an angle (about 25 degrees in one example), the strip appears to move up and down in the image.

It has been found that the strength of the scroll bar effect can be increased by beveling the 116 rear edge 118 of the magnet. This will gradually weaken the magnetic field as the image clears the magnet. In other aspects, magnetic transfer occurring at an acute angle of one of the magnets can rearrange the positioning of the sheets and degrade the visual effect of the scroll bar. In a particular embodiment, one of the corners of the magnet is chamfered at an angle of 30 degrees from the plane of the substrate. An alternative method is to secure the sheets before they pass the trailing edge of the magnet. This can be accomplished by providing a UV (ultraviolet) source for, for example, a UV hardening carrier on the path of the magnet or providing a source of drying for the evaporative carrier.

Referring now to Figure 5A, an image in the form of a four-sided profile or closed region is shown in which the top end is curved downwardly. It is interesting to note that by observing the figure, it does not have a specific association with the generated image, and it is unrecognizable as a normal object; it is only a 2-D polygon. On the other hand, by observation, Fig. 5B has the same shape and the same sheet, but a cylinder is created by differently positioning the association with a known generally identifiable object. By providing a larger scrollbar across the span, the scrollbar adds a shadow to allow the user to feel the depth and three dimensional dimensions. In addition, by tilting the image of the pigmented sheet containing magnetically positioned in Figure 5B, the scroll bar appears to move across the image and its area changes as it sweeps across the cylinder. Figure 4B does not cause the same association; and when the bar moves in Figure 4B, its dimensions do not change. The change in area of the scroll bar experienced when viewing Figure 5B significantly makes the object look more realistic as the strip shrinks and then appears to expand in height. When it appears to move from the center to the side, it fills a smaller area and then fills a larger area. Furthermore, if FIG. 5A is compared with FIG. 5B, it will be seen that the scroll bar in the curved upper region of FIG. 5B appears to force the viewer to at least partially experience the presence of a white cover or the interior of the cylinder. When viewing view 4A, FIG. 4B or FIG. 5A, there is no such experience. There are therefore several advantages to using a scroll bar to fill a curved polygon. Figures 6 and 7 show two other shapes of scroll bars, where the scroll bars provide a sense of depth, movement, and where the actual area of the strip changes as it sweeps over the image.

Referring now to Figure 12, there is shown a shield comprising a profile in which a magnetically positioned pigmented sheet is placed which is positioned in the form of a scroll bar having a relatively large radius of curvature. It is important to select a radius of curvature that provides the desired sense of depth and curvature to best represent the resulting image. In all of the curved images described so far, once the image is tilted, the presence of the scroll bar provides a perceptible change in the area of the scroll bar and the bar appears to move past the image. This phenomenon is very noticeable and is illustrated in the sequence of Figs. 14A to 14D. The figures are identical images at different angles, each of which is at an increasing angle, and Figure 14A is incident perpendicularly. Compared to the simpler scroll bar of Figure 4B, where the strip only appears to move from one position to the next, there is no reference to the change in appearance of the strip itself at different locations. When the bar in Figure 4B appears to be moving, the bar at one location or another represents the same way. However, the strips in FIGS. 14A and 14B have a completely different shape; and when the image is tilted, the shape of the scroll bar is continuously changed, by the definition of the movement of the strip and the comprehensive effect, the combination and the rise and fall of the strip The deformation of the combined strip greatly increases the appeal of the image. Images with such features can be used as a security feature on an item, as a decoration, or as a component that provides phantoms for complex movements in visual art.

Although the shape of the change of the scroll bar shown in FIGS. 5B, 6, 7, 10, 12, and 13 is less obvious, when the strip is along a smooth curve, it still exhibits a changed shape. It also provides a phantom that moves horizontally and upwards or downwards.

Referring now to Figure 6, a circle is shown with a scroll bar spanning its diameter. When there is no scroll bar, the circle is only a circle perceived by the viewer, but the presence of the scroll bar provides the viewer with a phantom that the object is a half ball. Although the movement is not shown in the figure, when the image is tilted and the bar moves to the left, the viewer's eyes are significantly smaller along the circle scrolling, giving the viewer a three-dimensional sense and a sense of reality. Contrary to viewing a painting in which light and shadow and light are fixed, the motion image provides the viewer with an experience in which light and shadow move across the ball as the image is tilted. The scene provides a sensation of moving or rotating the object being viewed around the object. In addition, as the strip moves to the left, its area decreases, causing the viewer to have a feeling that the object is more than just a picture or photo. In fact, it is only a flat image, but the viewer can feel depth and motion and an improved viewing experience compared to viewing a "normal" image. It has three dimensions, movements, and shape changes that appear when the object is viewed and tilted.

In FIG. 7, when the scroll bar appears to sweep through the image, the area of the scroll bar that is faded to the dark area in the middle by the highlight has a substantially uniform area, however, when the strip fills the shape, the strip is represented. It is a curved trajectory along the upper and lower walls, and when it rises, it appears to protrude from the page and move from the lower center position to an upper extreme right or extreme left position. Here, the viewer experiences the lateral and upward movement of the strip, as well as the 3-D effect.

Reference is now made to Fig. 8A, which shows an alternate embodiment of the present invention in which two scroll bars are designed such that when the image is tilted in one direction, the scroll bars move relatively simultaneously; for example, a rightward pointing arrow, around the One of the scroll bars moves on one of the vertical axes.

In one embodiment of the invention, as shown in Figures 8B and 8C, an image having a "double scroll bar" is shown, wherein a portion 44' has a magnetic sheet positioned in a raised form and another portion of the image 44" has a magnetic sheet positioned in a recessed position. To achieve the raised position, a "roller" magnet is placed on the paper substrate. When the magnetic sheets located in the two regions of the image have different and reversed At the time of positioning (for example, +30 degrees and -30 degrees), a "double tilt" image is formed. At one of the oblique positions of the printed image, one portion of the image is dark and the other portion is bright. When the printed image is in one When tilted in the opposite direction, the areas change their light and dark areas to make the first image brighter and the second image darker. Depending on the desired design, the light and dark transitions can be from top to bottom and reversed. And from left to right and in reverse, depending on the positioning of the sheet. In Figures 8C and 8D, the bright strip 44' appears to have "moved" to one of the second parts of the image, and the contrast The size of the field 46', 48' has changed; in addition, the bright bar 44" appears as "has been" Moving "to one of the different portions of the image, and such comparison field 46", 48 "in size has changed.

According to Figs. 15A to 15D, an embodiment of the present invention will be described. An "independent clock" is shown in Figures 15B to 15D. In Figure 15A, the image is shown at a normal angle of incidence. In Figures 15B through 15D, the same print is shown tilted about the axis at different angles of incidence as indicated by the arrows. As can be observed, the scroll bar 150 shown in Fig. 15B has a large radius of curvature. When the view 15C is inspected, the scroll bar appears to be transferred to the left side, and the smaller concave shape on the inner surface of the clock is inverted. Scroll bar 152 appears to move backwards to the left. Figure 15D illustrates a reverse sensation movement in which, when tilted in the reverse direction, the larger scroll bar 150 shows that the larger bar 150 appears to shift to the right and the smaller bar 152 appears to scroll left. This behavior of light incident on the image simulates a real illumination situation on a real object such as a separate clock. As expected from a real object, illumination is simultaneously and reversely transferred in different zones. The phantom is therefore designed to follow the physics of natural light on real objects. The phantom is that the image is real. Referring now to Figure 15A, four elements 154a, 154b, 154c, and 154d including the clock are shown separately for ease of understanding, and each of the elements is printed one at a time at the correct location on the substrate to form what is shown in Figure 15A. The image shown. Although the image is formed by printing each zone and applying a magnet to form a sheet (the sheet aligns the arcuate pattern in reverse to produce two scroll bars), a sequential automatic printing method can be used to fabricate the image and similar image.

In an alternate embodiment of the invention, Figures 16F, 16G, 16H, and 16J exhibit an interesting and intriguing effect. Figure 16F is a printed image of one of the hemispheres in which the entire image is coated using a calibratable pigment sheet. As explained, the hemisphere is formed when the sheet is calibrated. When the substrate is tilted or the light source is changed, the printed image of the hemisphere shown in Fig. 16F appears as the image shown in Fig. 16G. When the image is tilted to the left from the normal around the vertical axis passing through the center, the bright hemisphere that looks more like a ball rolls at a varying tilt angle. The hemisphere in Fig. 16F can behave in any x-y direction, depending on the tilt angle, as compared to a scroll bar that can roll along a line in a plane. Therefore, tilting the image around the x-axis or y-axis can result in a moving appearance.

The shield in Figure 16J uses a combination of a scroll bar and a hemisphere effect to provide a very interesting combination of effects, where the shield and hemisphere behave as prominent pages. It is fabricated in a two-stage process in which a substrate is coated with a magnetic coating and formed and hardened as one of the hemispheres of Figure 16H. The second coating is applied via a mask or stencil to form the coating of Figure 161 to ensure that no other coating material covers the hemisphere. The second coating is placed in a magnetic field to create a scroll bar. The method of forming the above-described motion or dynamic hemisphere image is more complicated than the method of forming the scroll bar. The method will now be described with reference to Figures 16A through 16E. By way of example, the magnet 160a shown in Figure 16A illustrates magnetic field lines above and below a magnet forming two loops. The chart is only intended to show the two lines, but there is essentially a line leading edge that is created parallel to the lines and spans the entire magnet. As shown in Figure 16B, the magnets 160a, 160b used to create the hemispheres are more complex and, more specifically, more complex in 16C. Portions of the magnets in Figure 16B are cut away to illustrate certain magnetic field lines. As best seen in Fig. 16C, the field extending over the clusters of magnets 160a, 160b, and 160c is a dome shape, and the magnetic field extending below is also braided. As shown in FIG. 16D or FIG. 16E, by applying a coated substrate 167 having fluid ink in a braided magnetic field (which is only located above or separated from the magnets shown in FIG. 16D) When the magnets rotate, they support the middle of the field, and form a half-ball motion image. In the exemplary embodiment, the relative rotational speed of the magnets or images is about 120 rpm. The image is then removed from the area of the field and hardened. Depending on the magnetic properties of the particles and the viscosity of the ink carrier, the rotation speed of the magnets can be slower or faster than 120 rpm. However, if the rate is too low, the quality of the image will be degraded.

Figure 17A is an illustration of an alternate embodiment that is similar to the image illustrated in Figure 16F but is reversed. A simulated magnetic field from a semi-spherical magnet is shown in Figure 17A. This is the shape of the field that produces the image shown in Figure 17C. The north pole of the magnet is at the top and the particles are calibrated in a concentric manner in a funnel-like fashion. Field 194 in Figure 17B is shown and aligns a sheet 193 disposed in carrier 192 on substrate 191 with a positioning similar to a funnel that follows a magnetic field line. In contrast to the hemisphere effect, the field produces a bright dynamic point 192 in the middle of the image 191; and the similar funnel calibration of the sheets produces a dark dynamic point in the middle of the image. Although the fields illustrated and described are formed from permanent magnets, electric or electromagnetic fields may be used in various embodiments. Of course, the field must be compatible with the particles such that the particles can be positioned by a particular field.
