Abstract

The golf ball with the alignment guide includes at least two printed lines. The first print line includes arrows at both ends of the print line that serve as alignment guides. The second print line is printed in a different color than the first print line. The second printed line is readable when viewed from the first angle and loses visibility when viewed at the second angle so that the second printed line does not distract the golfer's eyes from the alignment guide. The second printed line may comprise metallic particles to enhance such effects.

Description

Alignment guide for golf ball {ALIGNMENT GUIDE FOR A GOLF BALL}

The present invention relates generally to indicia on golf balls used as alignment guides. More specifically, the invention relates generally to two-line printing wherein the first line is an alignment guide and the second line loses visibility when viewed in a preselected angle or group of angles.

Many golf balls include markers. These markers are often identification words and / or graphics to assist the golfer in identifying the ball as his ball during play. In addition, the marking may also indicate the type of ball, such as the manufacturer's name, logo or other identification mark. The mark may also indicate the specific brand name of the ball so that the golfer can immediately select the desired ball from the group of balls.

Some balls use markers for the additional purpose of providing an alignment guide for the golfer when it is possible for the golfer to rotate the ball. The alignment guide is typically a printed word or graphic with an arrow at the end of the line. The printed words / graphics form lines that direct the golfer's eyes to arrows to assist the golfer in aligning the golfer's shots.

Printed words / graphics are often the trade name of the ball and / or ball manufacturer that allows the golfer to identify the golfer's ball throughout the round of golf. Many blank trade names are short enough to fit well on one printing line. The single printed line provides a clear basis for the "arrow" of the alignment guide since the golfer's eyes are not distracted from the alignment arrow. However, some blank trade names are long and require two or more printing lines. When two or more print lines are placed in proximity to the alignment arrow, the golfer's eyes may be distracted by the second print line, making the alignment guide less useful or even useless to the golfer, depending on the sensitivity of the golfer.

Thus, there is a need in the art for an improved alignment guide that uses multiple printed lines.

In one aspect, the present invention provides a golf ball comprising a mark having a first line and a second line. The first line includes a graphic formed from a first color medium having a first color. The second line includes a second graphic formed from a second color medium having a second color different from the first color. The second color is selected such that the second line is readable when the marker is oriented to the incident light at the first angle and the second line loses visibility when the marker is oriented to the incident light at the first angle.

In another aspect, the present invention provides a golf ball having a first line and a second line, the golf ball having an alignment guide comprising a mark formed on a surface having a background color. The first line includes a graphic formed from a first color medium having a first color, the first line being an alignment guide. The second line includes a second graphic formed from a second color medium having a second color different from the first color. The background color and the second color have low contrast, and the background color and the first color have high contrast.

Other systems, methods, features and advantages of the invention will be or will become apparent to those skilled in the art upon reading the following figures and detailed description. All such additional systems, methods, features, and advantages are intended to be included within the description and summary, within the scope of the invention, and protected by the following claims.

The golf ball includes a mark having a plurality of printed lines, where only one printed line is used as the alignment guide. The alignment guide is provided by arrows located at each end of only one print line. The other printed line (s) are printed with ink that loses visibility, i.e. disappears when viewed by the golfer at the selected angle or set of angles. This effect is an optical illusion that allows the golfer to ignore printed lines that are not part of the alignment guide, allowing the golfer to focus on the alignment guide without being distracted by other printing lines proximate the alignment guide.

1 shows an embodiment of a golf ball 100 having a mark 110 disposed on the surface 118 of the golf ball 100. The golf ball 100 may be any type of ball known in the art used for golf games or golf practice, such as a solid ball or a round ball. Golf ball 100 includes a core, one or more intermediate solid layers, viscous or wound layers, and a cover.

Surface 118 may be any type of outer or outermost surface for golf balls known in the art. Surface 118 may comprise the surface of the cover of golf ball 100, which cover may be made of rubber, polymer, or plastic material. Surface 118 may also include any coating layer applied to the surface of the cover of golf ball 100. For example, the coating layer may comprise a paint layer, a sealing layer or other type of coating. The cover of golf ball 100 may be any type of golf ball cover known in the art, such as rubber, ionomer material or polyurethane material.

Surface 118 has a color that is visible to the golfer. The color of the surface 118 may be considered to be the background color for the marker 110. In many golf balls, surface 118 is white. The fine white shade of the surface 118 can be selected from any white shade. In other embodiments, surface 118 may have other colors. Other common colors for golf balls include green, orange and yellow, although any color may be used.

The color of the surface 118 may be accomplished by any means known in the art. For example, in some embodiments, the color of surface 118 may be provided by a paint layer, typically a paint solid suspended in a polymer. The color of the paint layer is provided by the solids by the color of the paint solids, or by a mixture of colors provided by the paint solids of the plurality of colors. In other embodiments, the color of surface 118 may be provided by particles mixed in the material of the cover layer of golf ball 100, such as titanium dioxide. In another embodiment, the color of surface 118 is imparted to the cover layer of golf ball 100 using any method known in the art, such as sublimation dying or infusion dying techniques. Prepared dyes. In other embodiments, the perceived color of the surface 118 by the golfer may be an outer layer of a combination of these and other colors of the ball. For example, the cover material may comprise titanium dioxide and the coating layer may comprise silver metallic particles. Combinations of these color layers can give surface 118 a brightly shiny white color appearance.

Marker 110 may be marked on surface 118 or may be any method known in the art, such as printing, dyeing, pad printing, stamping, inkjet printing, masking, screen printing, painting, attaching as labels, and the like. May be a coating disposed on surface 118. In some embodiments, the marker 110 may be locally integrated with the surface 118 by a dyeing process, such as a sublimation dye or infusion dye. For clarity, “printing” herein is any method that can be used to apply the marking 110, portions of the marking 110 and / or components of the marking 110 regardless of the actual method used. Can be used to refer to. For example, a "print line" can represent a series of printed characters, dyed characters, and the like.

Mark 110 may be formed from any type of color medium known in the art, such as dyes, paints, and inks. In some embodiments, more than one type of color medium may be used. Any sub-part or component of the marker 110 may be monochromatic or may include multiple colors, although it is contemplated that multiple colors may be used for different portions of the marker 110. For clarity, "color medium" will be used herein to mean any type of color medium, such as ink, dye, paint, color particles, and combinations thereof, regardless of the type of color medium. Certain examples may describe particular color media materials.

The mark 110 may be any type of marking formed on the ball. Marker 110 may include any type of graphic, such as alphanumerics, figures, symbols, or a combination thereof. Mark 110 may be an identifier that allows a golfer to more easily identify a ball as its ball during play. For example, the indicia 110 may include the name, brand name and / or logo of the ball manufacturer, ball name, trade name, trade name and / or logo, ball number, custom graphics, and combinations thereof. For the sake of clarity herein, "character" may be used to indicate any type of marking that forms part of the marking, regardless of the particular type of marking.

Many golf balls include alignment guides to assist the golfer in aligning the shot. The alignment guide is particularly useful when it is on the green, as it allows the golfer to rotate the golf ball as long as the distance and vector of the golf ball to the hole are not changed. The alignment guide can take many forms, but is typically a line with arrows at each end that have vertices facing away from each other. Although a solid line may be provided, some markers include an alignment guide that uses a line of printed graphics with arrows located at the ends. This alignment guide is shown as first print line 12 in FIG. 1. The arrow graphic 114 is located at the beginning and end of the first print line 112, ie at both ends of the first print line 112. The golfer's eye can easily determine the line of the printed graphic as a line corresponding to the solid line so that the golfer can effectively use the first printed line 112 as the alignment guide.

In many cases, however, the marking required may use multiple print lines. Mark 110 includes a second printed line 116 as shown in FIG. 1. Any line of marker other than the alignment guideline is referred to herein as "an additional line". Marker 110 may include any number of additional lines.

When the mark 110 includes multiple print lines or coverage areas, print lines not intended to function as alignment guides may distract the golfer's eyes from the alignment guides. Thus, the marker 110 provides a first color medium with a first color in the first print line 112 and a second color medium with a second color in the second print line 116. In some embodiments, the first color medium is the same as the second color medium, but the first color is different from the second color. In another embodiment, the first color medium is different from the second color medium, and the first color is also different from the second color.

The color and / or color medium of the additional line of the marker 110 indicates that the additional line of the marker 110 is visible when the marker is oriented in a selected angle or group of angles for the incident light and / or golfer's viewing angle. It is chosen to lose, that is, disappear. However, from any other angle, the additional line of marker 110 is clearly readable. However, the color and / or color medium of the alignment guide of the marker 110 is chosen to be clearly readable at all viewing angles.

2-5 illustrate examples of how the visibility and / or readability of individual printed lines on golf ball 100 changes as the golfer's viewing angle changes. 2 and 4 show the golf ball 100 viewed from the first observation angle α. At the first viewing angle α, both the first print line 112 and the second print line 116 are clearly visible and / or readable. The first viewing angle α may be any angle, but in some embodiments the golf ball 100 is any angle not seen from the golfer's address position or putting stance. Additionally, golf ball 100 is rotated such that incident light does not shine directly above first print line 112 and second print line 116.

3 and 5 show the golf ball 100 viewed from the second viewing angle [theta] when the golfer is in an address position or putting stance. The first observation angle α is different from the second observation angle θ. Additionally, golf ball 100 is rotated such that incident light is more directly reflected on first printed line 112 and second printed line 116. When the golfer sees the golf ball 100 from the second viewing angle θ, the second printed line 116 loses visibility, i.e. disappears.

While not wishing to be bound by any particular theory as to why the second printed line 116 loses visibility, i.e., disappears, such an optical illusion in which the print loses visibility and the color selection of the second printed line 116 and And / or a combination of color selection of second print line 116 and surface 118. Color may be measured or represented using any method such as CIELAB, CIEXYZ, Pantone color chips and names, and the like. High contrast colors for the surface 118 will be visible and readable at most or all angles, while low contrast colors will be readable at some angles and will tend to lose or disappear at other angles. For example, if the golf ball 100 is white, light colors (grey, metallic silver, pale yellow, pink, etc.) are low contrast colors that may tend to lose visibility or disappear at certain angles. Darker colors (black, dark red, dark blue, dark green, etc.) are high contrast colors that tend to be visible and readable at all or almost all angles.

In some embodiments, for example, the second printing line 116 has a color selected to be similar to the color of the surface 118 of the golf ball 100, and the color of the first printing line 112 is the surface 118. ) Is a very contrasting color. The color difference is large enough to make the second print line 116 readable and discernable when viewed from some angle, but when the incident light strikes the second print line 116 at a selected angle or group of angles The color difference between the print line 116 and the surface 118 is minimized so that the second print line 116 appears to mix with the color of the surface 118. Due to the high contrast between the color of the first print line 112 and the color of the surface 118, the first print line remains very high visibility and readable with respect to the background of the surface 118. For example, for a typical white surface 118, the color of the first print line may be black or similarly dark hue, and the color of the second print line 116 may be gray or silver.

One reason why the color of the second printed line 116 is colored with the color of the surface 118 is that the angle of the incident light is the ratio of diffuse and specular reflection from the surface of the golf ball 100 or the intensity of the specular component of the reflected light. It may be because it can change. In diffuse reflection, the reflected light is scattered somewhat randomly by the imperfections in the surface (s) of golf ball 100. High proportions of diffuse reflection are familiar as matt surfaces. In specular reflection, the reflected light is reflected in a single direction. High proportions of specular reflection are familiar as glossy surfaces. Very high proportions of specular reflection are mirrors or mirrors. This change in the ratio of diffuse and specular reflection or the intensity of specular reflection is particularly such that reflective particles are used in the color medium for the second print line 116 or any additional line of the marker 110 or the second print line 116. Or if the color medium of any cover coating has a glossy or high gloss finish.

6-9 illustrate how the change in the ratio of diffuse reflection to specular reflection can be made. FIG. 6 shows an enlarged view of the second printed line 116, where each individual character 120 of the second printed line 116 is formed of a plurality of reflective particles suspended in matrix material or substrate 124 (FIG. 122). In some embodiments, substrate 124 may be clear or transparent, while in other embodiments, substrate 124 is colored such that substrate 124 includes an opaque or translucent (partially opaque) color. For example, if the overall color seen of the second printed line 116 appears to be silver, the substrate 124 may be provided with a gray color pigment. The metallic or shiny appearance can then be provided by the reflective particles 122, which can be silver particles having metallic sheen and / or high gloss. Reflective particles 122 may be any type of particles known to have metallic sheen and / or high gloss such that high reflectivity is obtained. In another embodiment, all the colors shown of the second printed line 116 are provided by the reflective particles 122. For example, if the second printed line 116 appears to be silver, silver particles with metallic sheen and / or high gloss provide the perceived color.

Reflective particles 122 may be randomly oriented in substrate 124 as shown in FIG. 7. In this configuration, the highest level of brightness from the particles does not necessarily have to occur at the same angle. As shown in FIG. 8, the first incident light beam 140 and the second incident light beam 3 are applied to three different reflective particles, that is, the first particle 126, the second particle 128, and the third particle 130. 142 and the third incident light ray 144 strike each. Each incident ray is parallel to the other incident ray. Due to the random orientation of each particle, the incident light beams strike the particles at different incident angles, where the first incident light beam 140 is at a first incident angle β (measured from normals to the particle surface N). The first particle hits the first particle, the second incident ray 142 strikes the second particle 128 at the second incident angle δ, and the third incident ray 144 is the third particle at the third incident angle ε Impinging on 130, these angles of incidence are different. Because of the law of reflection, since the reflected light makes the same angle as the incident light with respect to the normal of the surface, each particle produces a reflected light at a slightly different angle, with the first particle 126 being set to the first reflected angle γ. Generates a first reflection beam 150, the second particle 128 generates a second reflection beam 152 at a second reflection angle ρ, and the third particle 130 is made of a third reflection angle η. Generates 3 reflected rays 154. These different angles are all different from each other, creating a diffuse reflection. In addition, no particles produce reflected light that returns to the same path as the incident light. Such light rays are typically considered to be the highest reflection levels and can often "dazzle" the eyes by bright light or glitter.

This glare effect is shown in FIG. 9, where incident light impinges on at least one particle such that the highest reflection level is achieved. The fourth incident light ray 146 strikes the first particle 126 at the fourth incident angle λ to generate the fourth reflected light ray 156 at the fourth reflection angle μ. The fifth incident light ray 147 strikes the second particle 128 at the fifth incident angle of zero degrees, and moves the fifth reflected light ray 157 oppositely in the same path as the fifth incident ray 147 at the fifth reflective angle of zero degrees. ) The sixth incident light beam 148 strikes the third particle 130 at the sixth incident angle σ to generate the sixth reflected light beam 158 at the sixth incident angle τ. These reflections are also at slightly different angles to produce diffuse reflections, but when the incident light shines in a certain angle or in a range of relatively small angles, such as when light shines directly over the second printed line 116, as shown in FIG. Reflective particles 122 are seated in substrate 124 such that multiple reflective particles 122 can have the highest level of brightness. Also, with some particles that achieve extremely high levels of reflection, such as when the angle of reflection is 0 degrees or -15 degrees to +15 degrees, the glare effect of the glitter may be sufficient to alter the apparent ratio of diffuse and specular reflections. .

In addition, not all surfaces of the reflective particles 122 may be highly reflective. For example, if the reflective particle 122 is crystal, some facets of the crystal may have high gloss and metallic sheen, while other facets of the crystal may have a more matte finish. Thus, the reflective particles 122 may be more specifically oriented such that high reflectivity is achieved only when the mark 110 on the golf ball 100 is oriented in a specific or narrow angle range with respect to the incident light. Additionally, the golf ball can include a coating by particles that can act in conjunction with the printing of the second printed line 116 to enhance its reflection effect.

The glare of reflected light interferes with the eye's ability to recognize details such as print content, which is familiar to anyone who has tried to read a given surface in bright sunlight. For example, when the sun shines directly over a surface, words on that surface are difficult or impossible to see. Characters on the surface are not clearly visible or readable. However, the surface does not necessarily need to be shaded, but if the surface is slightly differently oriented so that the angle of the sun incident on the surface changes, such as when the observer moves with respect to the angle of the sun, a high contrast with the background of the screen is achieved. After the character on the surface becomes visible, the entire surface becomes readable. This effect is particularly common with backlit computer screens / displays.

Because the color of the second print line 116 is relatively similar to the color of the surface 118, that is, the color of the second print line 116 is in low contrast with the background color, Details become difficult to notice when golf ball 100 is oriented to exceed a threshold glare level. However, since the color of the first printed line is high contrast with the color of the surface 118, the first printed line 112 remains visible. This effect can be enhanced by the eye's tendency to ignore low contrast objects when other objects in the field of view have much higher contrast. Thus, the alignment guide provided by the first print line 112 is noticeable to the eye, while additional lines such as the second print line 116 are virtually ignored by the eye.

Thus, the golfer can immediately read all the lines of the marker 110 when the golf ball is oriented with respect to the incident light at an angle that does not cause high levels of specular reflection and / or high rates of specular reflection. Similarly, an additional line of marker 110 when golf ball 100 is oriented with respect to incident light at a particular angle or in a range of relatively small angles resulting in high levels of reflectivity and / or low rates of specular reflection for diffuse reflection. May lose visibility or blend into the color of the surface 118 of the golf ball 110. This ensures that only the first printed line 112, which is an alignment guide, is visible and readable to the golfer. This effect allows the golfer to efficiently use the alignment guide in use without being distracted or disturbed by additional lines.

Table 1 shows the CIELAB (formally, CIE 1976 L ^* , a ^* , b ^* color space) color spaces for various contrasts located on a curved white background and virtually ignored by the eye when viewed in a selected angle or range of angles. Provide a value. Table 1 also provides CIELAB values for white contrast. As is well known in the art, CIELAB is a three-dimensional mathematical representation of color based on the CIE 1931 color space chromaticity diagram. In CIELAB, L ^* represents the brightness of the color (0 means black, 100 means white), a ^* indicates the position between red / magenta and green [negative value represents green, positive value Represents magenta, and b ^* represents a position between yellow and blue (negative values represent blue and positive values represent yellow). Table 1 is provided by way of example only, and Table 1 is not intended to be a comprehensive table of values for the illusion of neglecting additional printed lines. Many other colors and color combinations are contemplated by various embodiments of the present invention.

TABLE 1

Selected CIELAB Value

Using exemplary values as a guide, the relative recognition difference (ΔE * ab) between white and other colors is obtained using the color difference equation (Equation 1) shown in FIG. 10 to obtain the Euclidean distance between them. By approximation. ΔE * ab is a measure used by the CIE to represent color differences in the CIELAB color space. As is known in the art, using this measure, the "just noticeable difference" (JND) is approximately 2.3 for CIELAB. JND means the minimum difference in the color space perceived by the eye. In other words, ΔE * ab below 2.3 causes the eye to interpret the two colors as the same color. Thus, ΔE * ab for the colors shown in Table 1 were expected to be relatively close to JND.

As shown in Table 1, the ΔE * ab values for light grey, metallic silver and dark grey ranged from about 3.79 to about 5.62, with all values within about 4 units of JND. Thus, in some embodiments, ΔE * ab for two colors effective for optical illusions that cause the eye to ignore additional printed lines is expected to be between about 2.3 and about 7. In other embodiments, this range may be narrower or larger, for example between about 2.3 and about 15. In most embodiments, it should be noted that ΔE * ab is equal to or greater than JND such that additional printed lines become readable at some angle. In addition, in particular, the metallic silver color has a minimum ΔE * ab for white, so that containing metallic particles can be ignored by the eye when viewed from some angles to aid the illusion that additional lines lose visibility. it means.
