Definitions

• the present invention is directed to a method for customizing game balls. More particularly, the present invention relates to a method, using a computer network, for soliciting orders for customized game balls, including, for example, allowing a user to transmit to the supplier, manufacturer or retailer customized indicia to be printed on the customized game balls.
• Computerized order systems are commonly used to customize purchases.
• Such computer customization systems have been unsuitable for ordering game balls because of the technical nature of the design criteria for game balls, and because of the burdensome process by which game balls are currently marked with custom indicia.
• the present invention is a method for soliciting or placing orders for customized game balls.
• the present method includes providing a game ball order form accessible through a computer network by one or more users from one or more remote sites.
• the present method further includes providing one or more possible design criteria, requesting the user to customize a game ball by entering at least one of the design criteria on the order form, requesting the user to submit the order form through the computer network, and receiving the order form.
• the design criteria may include customizing indicia to be printed on the surface of the game ball.
• Ink jet printing is the preferred method of printing the indicia on a game ball.
• Inkjet printing technology described in Appendix A below, as well as in U.S. Ser. No. 09/166,970, allows the manufacturer or printer to quickly customize the indicia to be printed on the game ball. This is because the image can simply be generated on or scanned into a computer and printed on the game ball as it appears on the screen. No dedicated printing plate needs to be etched. This quick and simple ink jet printing process makes it easy to solicit orders for customized game balls on which custom indicia are desired. Furthermore, with ink jet printing, no color separation process is necessary for complex images/colors. Thus, multi-color indicia patterns may be easily applied to game balls, as the different colors may be printed at the same time, without having to execute the printing process separately for each different color.

• the preferred method of the present invention for soliciting or placing orders for customized game balls using a computer network is shown in the flow chart of Fig. 1.
• the preferred method generally includes the step 105 of providing a game ball order form accessible through a computer network by one or more users from one or more remote sites, the step 110 of providing one or more possible design criteria, the step 115 of requesting the user to customize a game ball by entering at least one of the design criteria on the order form, the step 125 of requesting the user to submit the order form through the computer network, and the step 130 of receiving the order form.
• the preferred method may also include the step 135 of determining whether to accept the order represented by the customized game ball order form, and the step 140 of manufacturing one or more customized game balls according to the customized game ball order form.
• the step 105 of providing a game ball order form accessible through a computer network by one or more users from one or more remote sites may be accomplished by including such an order form on a manufacturer's, supplier's or retailer's website on the
• the order form may be sent to users via e-mail.
• the present method may include the step 120 of requesting various information from the user including, but not limited to, his or her name, address, place of business, work and home phone number(s), fax number, e-mail address, and credit card number and expiration date.
• a user may be asked to provide a predetermined identification number.
• this step 120 may also include requesting a predetermined identification number corresponding to that pro shop or retailer.
• the manufacturer, supplier or retailer may carry out the step 110 of providing to the user one or more possible design criteria which may be used to customize game balls.
• these design criteria generally define the characteristics of a specific game ball or game balls in general.
• the design criteria which generally apply to all types of game balls may include the color, quantity and type of game balls.
• the user is then asked to customize the desired game ball by entering at least one design criterion on the order form to be applied to the customized game balls (step 115).
• the user may enter the desired design criteria by either typing in the desired values for each criterion, or by selecting one value from a choice of values.
• the user may choose the particular type of game ball that he or she desires to customize. For example, the user may choose to customize golf balls, footballs, basketballs, baseballs, softballs, volleyballs, soccer balls, tennis balls, or other types of game balls.
• the user may then further customize the game ball by entering additional desired design criteria, including design criteria specific to the chosen game ball. For example, a user may select a golf ball as the desired type of game ball to customize. Because there are certain design criteria that apply specifically to golf balls but not to other types of game balls, the present method may include providing a specific set of design criteria corresponding to golf balls.
• This set of golf ball design criteria may include, but is not limited to, amount of compression, coefficient of restitution, level of spin, dimple pattern, shape of dimples, number of dimples, dimple size, overall dimple volume, percent of dimple coverage, distance level, core type, cover material, cover appearance, level of control, and trajectory level. Each of these design criteria will be discussed below.
• One advantage of the present invention is that a user can select any value within a range of acceptable values for certain design criteria.
• compression may be such a customizable design criterion.
• Standard golf balls are generally sold with a PGA compression of 70-110.
• the present invention may allow a user to specify any compression value from within a given range of acceptable values.
• the acceptable values will generally be determined based on acceptable manufacturing criteria or limitations. For example, a user may be able to choose any PGA compression in multiples of 5 from within the range of 70-110, thus allowing the user to obtain a golf ball that will perfect his or her personal golf game.
• the acceptable manufacturing criteria or limitations may dictate that the desired value of compression, hardness, etc. must be rounded to the nearest 10, nearest 5, nearest integer or nearest tenth of an integer. For example, if a user believes a Shore D cover hardness of 56.4 is ideal, this user would select 60 if the manufacturing criteria call for a multiple of 10, 55 if the manufacturing criteria call for a multiple of 5, 56 if the manufacturing criteria require an integer-value, or 56.4 if the manufacturing criteria allow increments of one tenth of an integer for the Shore D hardness value. This ability to select any value is discussed further below with regard to other customizable design criteria.
• the possible choices may include, for example, extra high, high, medium, low, or extra low, for a specific set of conditions such as, for example, launch, speed, or club type.
• the user may identify a specific value of maximum 8-iron spin such as, 8100 RPM, or a maximum driver spin such as 3400 RPM.
• This option to specify a maximum 8-iron or driver spin value is advantageous as it allows a user to tweak the value of spin in order to perfect his or her own golf game.
• the selected value for the maximum 8-iron spin may be chosen from a range of values such as, for example, 6000 - 10000 RPM, with acceptable manufacturing criteria being increments of 500.
• the selected value for the maximum drive spin may be chosen from a range of values such as, for example, 2000 - 5000 RPM, with acceptable manufacturing criteria being minimum increments of 500.
• the possible choices may include, for example, icosahedron, dodecahedron, single radius icosadodecahedron, dual radius icosadodecahedron, tetrahedron, and counter rotating double helix.
• the possible choices for the shape of the dimples on the golf ball may include, for example, circular, tear-drop, ellipsoid, or any combination of these shapes.
• the possible choices for the distance level of the customized golf ball may include, for example, average, long or extra long.
• the possible choices for core type include, for example, wound, solid or liquid, single layer, or multi-layer.
• the cover material design criterion for each layer of the cover may allow a user to select among several different materials such as, for example, balata, polyurethane, metallocene catalyzed polyolefm, polyamide, elastomer, titanium, ionomer, or particular blends containing ionomer or other materials, for example, ZinthaneTM II (Trademark of Spalding Sports Worldwide, Inc., Chicopee, MA), TerthaneTM (Trademark of Spalding Sports Worldwide, Inc., Chicopee, MA), Surlyn ® (Registered Trademark of E.I. Du Pont, Wilmington, DE), or Iotek ® (Registered Trademark of Exxon Corp.).
• the user may select, for example, low, average, high or extra high.
• the trajectory level is another possible design criterion, allowing a user to select, for example, an ultra low, low, medium, high, or ultra high trajectory level.
• the "cover appearance" referred to above may include the incorporation of clear “windows” in the outer cover of the ball, allowing the underlying layer, such as a mantle layer, to be partially visible.
• windows are provided in U.S.
• cover thickness Other golf ball design criteria not already mentioned above, which the present method may allow a user to customize, include, but are not limited to, cover thickness
• construction type e.g., two-piece, wound, multi-layer
• cover Shore D hardness e.g., 40 - 70, increments of 1
• One important advantage of the present method is the ability for a user to quickly and easily order game balls personalized with custom indicia or logos.
• the preferred method of applying custom indicia or logos to a game ball is to use an ink jet printer. This method of forming indicia on a game ball is fully discussed and disclosed in U.S. Ser. No. 09/166,970, which is the parent application to this application.
• Inkjet printing allows multi-color indicia patterns to be easily applied to game balls, because the different colors may be printed at the same time, without having to execute the printing process separately for each different color.
• indicia may be applied to a game ball using an ink jet printer.
• the indicia may be printed directly onto the game ball by the ink jet printer.
• the indicia may be printed onto a pad, then is transferred from the pad onto the game ball. Since the pad is just a transfer medium, not a custom-etched part, the same pad can be used to print many different indicia. This facilitates a short-run custom manufacturing facility.
• a further advantage of the present invention is that rather than applying indicia onto a completely finished game ball, the indicia may be applied to a game ball before any clear finishing or protective layers are applied to the ball. For example, golf balls are often manufactured with a clear protective top coat to maximize durability.
• a preferred embodiment of the present method includes the step of manufacturing a certain number of customized game balls according to the customized game ball order form, it is easy to apply the indicia or logo before applying any desired protective layer.
• the next step 120 of the present method is to ask the user to provide any information to complete the current order. For example, the user may be asked to provide his or her name, address, place of business, work and home phone number(s), fax number, e-mail address, and credit card number and expiration date. In some circumstances, a user may be asked to provide a predetermined identification number.
• the user is asked to submit the completed order form to the manufacturer, retailer or supplier over the computer network, thus placing the order (step 125).
• the user may be given alternative options before submitting the completed form. For example, the user may be able to clear the form and start over, revise the form, save the form in a database for a predetermined amount of time before actually placing the order, or cancel the order altogether.
• the present method includes the step 130 of receiving the completed order form by a second party, generally the party who will fill the order (e.g., the manufacturer, supplier or retailer).
• the party who receives the completed order form may carry out the step 135 of determining whether or not to accept the order.
• This feature of the present invention prevents the manufacturer, supplier or retailer from attempting to fill an impracticable or impossible order, or from filling an order for a user who has provided a false, invalid or cancelled credit card.
• the order may be filled (step 140).
• the manufacturing process may be integrated as part of the overall customization process. This integration may be accomplished by, for example, translating the design criteria data into manufacturing control data to be used directly by the machinery at a manufacturing facility.
• the manufacturing facilities which operate to create the customized game balls, generally comprise different machines operated in a series for making the game ball. For example, there may be a ball-molding apparatus which can mold a golf ball with the dimple type selected by the user on the game ball order form.
• Figure 2 illustrates an integrated manufacturing process for customizing the dimple type on a golf ball. After the customized order form is accepted (step 135 of Figure 1), the order may then be received by the manufacturing facility (step 210).
• the present invention may include the step 220 of reading the specific data or information corresponding to the dimple type chosen by the user. Generally, this specific data would be read by the ball-molding apparatus, so the ball-molding apparatus may then carry out the step 230 of selecting an appropriate mold for the golf ball co ⁇ esponding to the dimple type chosen by the user.
• the next step 240 may include setting up the ball-molding apparatus with appropriate values to prepare the machine to mold the custom balls. For example, once the appropriate mold is selected according to the custom dimple type data, the ball- molding apparatus should put the corresponding mold into place for molding. Further, the apparatus should be set up to make the proper number of molded golf balls. Finally, the present method may include the step 250 of activating or running the ball-molding apparatus to physically mold the balls as desired by the user.
• Figure 3 illustrates an integrated manufacturing process for customizing the compression value of a golf ball.
• the order may then be received by the manufacturing facility (step 310). As already explained, this may be accomplished by, for example, sending the order to the manufacturing facility via e-mail or by loading the data from the order form onto a data base which may be accessed by the manufacturing facility.
• the present invention may also include the step 320 of reading the specific data or information corresponding to the compression value chosen by the user. This specific data may be read by, for example, a polymer forming apparatus.
• the polymer forming apparatus may carry out the step 330 of selecting and making an appropriate polymer formulation for the golf ball co ⁇ esponding to the compression value chosen by the user.
• the next step 340 may include preparing the polymer forming apparatus to create the appropriate formation. For example, once the appropriate formulation is selected (step 330) according to the custom compression value, the polymer forming apparatus should set various values to make the proper amount of polymer for the desired number of golf balls. Finally, the present method may include the step 350 of activating or running the polymer forming apparatus to physically compound the polymer corresponding to the desired compression value.

• the ink jet printer is activated (step 430) for printing indicia on the customized game ball.
• This activation step 430 may include, for example, loading the data or information which defines the indicia into the printer memory, placing the appropriate game ball in place for printing, and running a preliminary check on the printer. Then the printer may print the indicia directly or via an intermediate pad onto the game ball (step 440).

• One method of forming an image on a game ball using ink jet printing is an indirect printing technique which involves printing indicia on a transfer medium using an ink jet printer and then transferring the image from the transfer medium to the game ball surface.
• Another method is to print directly on a specially treated surface of a game ball using an ink jet printer.
• a golf ball 608 has a central core 610, which can be solid, liquid, gas, gel, wound, or a combination of these, and a dimpled cover 612 su ⁇ ounding the core.

• FIG. 8 A method for directly ink jet printing on a golf ball is shown in Figure 8. As shown at 840, a golf ball is primed with an ink retaining primer. After the coating has been applied, an image is ink jet printed directly onto the surface of the primer at 842. After the image has been applied, the surface of the ball and the indicia optionally can be coated with a suitable top coat at 844.
• the method of ink jet printing as described herein can be used on curved surfaces of game balls such as golf balls, basketballs, baseballs, softballs, and the like, and is particularly useful on golf balls. It can be difficult to print on the curved and dimpled surface of a golf ball because the dimples tend to distort an image printed thereon and because the plastic cover of a golf ball, which typically is made of ionomer, balata, or polyurethane, has a low surface energy. The low surface energy of the ionomer cover makes adhesion difficult and also causes ink to form into beads when placed on the cover, thereby blurring the printed image.
• One way to overcome the beading problem is by applying a primer coat to at least the portion of the ball surface upon which the indicia are to be printed, the primer coat containing a material which promotes absorption, adhesion, and/or clarity of the indicia.
• Suitable materials of this type to use in the primer coat of a game ball such as a golf ball include talc, amorphous silica, bentonite clay, magnesium silicate, or the like, or a combination of these.
• the material which promotes absorption, adhesion, and/or clarity of the indicia is incorporated into the cover itself.

Examples of polymer resins or resin components which are used in conventional ink jet printing inks include polyurethanes, polyesters, polyketones and polyacrylates. In the case of a UV curable ink, the resin components could be, for example, oligomers.
• the ink composition and the composition of the ball cover or primer layer to which the indicia are to be applied may be selected such that the surface tension of the ink is appropriately related to the surface properties of the substrate to which it is to be adhered.
• Inks contemplated to be suitable for ink jet printing typically have a viscosity of from about 1 to about 20 cps measured at the temperature of application.
• UV curable inks can be used in accordance with the method of ink jet printing as described herein. Most commercially available UV inks are not suitable for ink jet printing due to the high concentration and size of the pigments and fillers in these formulations.
• a UN ink suitable for an ink jet printer should incorporate very finely divided pigments (about 0.1 micron or alternatively less than 100 Angstroms), dissolved dyes, or combinations of dyes and finely divided pigments.

• a suitable transfer medium is one which has a surface that allows for good clarity of the indicia printed thereon while providing for transfer of the image onto the game ball surface.
• One contemplated transfer medium is a silicone pad.

• the photoinitiator is selected to respond to the wavelength of UV radiation to be used for photoinitiation. It is also important to consider the color of the ink in selecting the photoinitiator because, as indicated above, it is necessary for the UV light to penetrate the ink composition to initiate the cure. More specifically, penetration is sometimes required in order to cure the portion of the ink which is beneath the surface. Penetration typically is most difficult when black or white pigments are used.
• Non-limiting examples of photoinitiators to be used in conjunction with black pigment include sulfur-type photoinitiators such as isopropyl thioxanthone, and benzophenone and its derivatives including acetophenone types and thioxanthones. Photoactivators can be used in conjunction with one or more photoinitiators.

• a solvent When a solvent is used in the UV curable ink, it typically is a liquid with a fast to moderate evaporation rate which, upon partial evaporation causes the ink to be tacky, and thereby promotes transfer onto and off an ink pad.
• a solvent also can be the medium in which a photoinitiator is dissolved.
• suitable solvents include aromatic solvents such as toluene, xylene, and ester types such as butyl acetate.

ATH may be employed in an amount of 10 - 32 wt %, alternatively 20 - 30 wt %. It is believed that ATH loadings up to at least 50 wt % based upon the weight of (uncured) ink may be useful for providing an overall balance of properties. Greater quantities of ATH can be used when a low cost ink is desired and durability requirements are not stringent. Lower quantities of ATH are useful when higher durability is needed. The ATH can be used in a quantity appropriate to impart to the ink a balance of properties such as pad transfer and durability of the ink.

Higher and lower UV lamp intensities, distances, and exposure times may be used as long as the cured ink meets the applicable durability requirements. Excess UV exposure is avoided to prevent degradation of the substrate.
• the ink can be UV cured prior to application of any top coat.
• the pad to be used for transfer of the UV ink may contain silicone. This type of pad has good elasticity, durability and softness and an appropriate surface tension. Other types of pads also can be used.
