Definitions
- the present invention relates generally to color matching, and more particularly, to a method and system for providing a color matching solution.
- Products today are offered to consumers in a wide variety of colors. Consumer products may be colored by means of colorants, dye or paint. Color matching is required in a variety of areas, including textiles, plastics, various synthetic materials, prosthetics, dental applications, and paint applications, due to the many variations in color, due to the wide variations in shades and hues of any given color and color variations in an article. The actual color produced in a given article may vary due to a number of factors. For example, textile colors vary according to fiber composition. Colorants for plastic vary according to the plastic composition. Painted articles vary in color depending on any number of factors, such as paint composition, variations in the paint application process, including application method, film thickness, drying technique and number of layers.
- a paint manufacturer supplies one or more paint formulations for the original paint color to refinish paint shops. By supplying a plurality of formulations or variants for a particular color, the paint manufacturer accounts for factors that affect the actual color. Matching of dyes or colorants for other applications is also done through formulations for a particular color. Typically, for any of the above application, the formulations for a particular color are distributed on paper, microfiche, and/or compact disks (CD). A color tool, composed of swatches of the variants for each color may also be produced and delivered to each customer. The customer must select a formulation most closely matching the existing color of the article.
- a computer system for providing color solutions to a customer includes a first module located at a remote location.
- the first module receives a solution request from an operator.
- a second module is coupled to the first module via a computer network.
- the second module is located at a central location and includes a composite solution database and a search routine coupled to the composite solution database.
- the second module is adapted to receive the solution request from the first module.
- the search routine is adapted to search the composite solution database and determine a paint color solution as a function of the solution request.
- a computer based method for providing color solutions to a customer over a computer network includes the steps of receiving a solution request from an operator located at a remote location, delivering the solution request from the remote location to a central location over the computer network, and searching a composite solution database and determining a paint color solution as a function of the solution request.

- the system 100 includes a first module 102 located at a remote location 104, such as a customer site.
- the first module 102 is implemented on a computer (not shown), such as a personal computer or wireless computing device.
- the first module 102 is adapted to be operated by a user or operator 106, i.e., the customer.
- the operator 106 inputs a solution request to the first module 102.
- the solution request includes a paint identifier (or color code) which identifies the color of a subject part 108 and color measurements from a color measurement device 110.
- the part may be any colored sample or a painted component.
- the color measurement device 110 is used to provide color measurements, i.e., an indication of the actual color of the subject part 108 to be matched.
- the color measurement device 110 is a spectrophotometer such as is available from X-Rite, Incorporated of Grandville, Ml as model no. MA58.
- the color measurement device 110 may be a spherical geometry color measuring device, a digital camera or other suitable device.
- the first module 102 is coupled to a second computer based module 112 located at a central location 114, such as the paint manufacturer's facility.
- the first and second computer based modules 102, 112 are coupled across a computer network 116.
- the computer network 116 is the internet.
- the second module 112 receives the solution request from the operator 106 via the first module 102 and the computer network 116.
- the second module 112 includes a composite solution database 118 and a search engine or routine 120.
- the search routine 120 is adapted to search the composite solution database 118 and determine a paint color solution as a function of the solution request.
- a computer based method for providing paint color solutions to a customer will now be explained.
- the solution request from the operator 106 located at the remote location 104 is received.
- the solution request is delivered over the computer network 116 from the remote location 104 to the central location 104.
- the composite solution database 118 is searched and a paint color solution is determined as a function of the solution request.
- a system 300 for managing and providing color solutions includes three databases: the composite solution database 118, a color measurement database 302, and a customer and solution usage database 304.
- a customer interface 306 is implemented on the first module 102 located at the remote location 104.
- the customer interface 306 allows the operator 106 to log on to the system, communicate with the system 100,300, e.g., to request color solutions, and to receive color solutions from the system 100,300.
- the customer interface 306 is graphical in nature, and, preferably, is accessed through a generic world wide web (WWW) browser, such as MicrosoftTM Internet Explorer, available from Microsoft of Redmond, Washington.
- WWW world wide web
- the customer interface 306 may be implemented in hypertext markup language (HTML), the JAVA language, and may include JavaScript.
- the system 300 also includes several processes: a solution creation process 308, a quality control process 310, a formula conversion process 312, a variant determination process 314, and a derived tolerance process 316.
- a solution creation process 308 a quality control process 310
- a formula conversion process 312, a variant determination process 314, and a derived tolerance process 316 Each of the databases 118, 302, 304 and the processes 308,310, 312, 314, 316 will be explained further below.
- a fourth process block 402 the operator 106 measures the color of the part 108, using the color measuring device 110.
- the color measuring device 110 may be a spectrophotometer, a digital camera or other suitable device.
- the color measuring device 110 is a spectrophotometer which measures reflective values.
- the color measurements of the part 108 are taken at multiple angles using industry known methods.
- the color measurement data along with other identifying data are transmitted over the computer network 116 to the central location 114.
- the identifying data includes at least a color or paint code which represents the original color of the part 108.
- the identifying data includes a customer identification number or identifier, vehicle information (make, model, model year), color code and desired paintline. Paintline refers to different types of paint available from the manufacturer, which typically balance product features and cost.
- the solution request is analyzed by the quality control analysis process 310 to ensure that the data contained in the solution request is accurate. For example, the quality control analysis process 310 compares the given color code with the color measurements to make sure that it is the right color. In the case of automotive paint matching, the color code and vehicle data are compared to make sure that the color was available on the particular model. Similar comparisons may be made for textile, plastic or other substrate with identifiable color tracking information. If the solution request is inconsistent, the inconsistencies are reported to the operator 106 in a sixth process block 408. The operator 106 is requested to make corrections through the customer interface 306. [0028] Once the solution request has been approved by the quality control analysis process 310, control proceeds to a seventh process block 410. In the seventh process block 410, the search routine 120 searches the composite solution database 118 for a color solution (formulation) which most closely matches the solution request. The search routine 120 compares the color solution with tolerances determined by the derived tolerance process 316 (see below).
- a second decision block 410 if the color solution is within the tolerances, than the color solution is sent to the operator 106 at the remote location 104 in a eighth process block 414. If the color solution is not within the given tolerances, than control proceeds to a third decision block 416. In the third decision block 416, the solution creation process 308 attempts to adjust the solution to be within tolerances and/or creates a new solution. If the color solution can successfully adjust the solution or create a new solution, the new solution is sent to the operator 106. Otherwise, the operator 106 is informed that no solution is feasible in a ninth process block 418. [0030] 2. Databases
- the system 100,300 includes several databases containing information used in and generated by the various processes 120, 304, 306, 308, 310, 312, 314, 316. The use and content of each of these databases are described below.
- the composite solution database 118 is the main database of the system 100,300 and contains all current formulations or variants for each color.
- the paint or color code "4M9" may have multiple formulations contained in the database 118.
- the composite solution database 118 is coupled to the search routine 120, the solution creation process 308, the quality control analysis process 310, and the customer and solution usage database 304.
- the composite solution database 118 contains measurement data in the form of color values.
- Color values refer to color attributes used to quantify color. Examples include, but are not limited to, reflectance values, tristimulus values, and color space values. One example of color space values are defined by L*a*b * .
- L * represents luminous intensity
- a* represents a red/green appearance
- b* represents a yellow/blue appearance
- Another example of color space values are defined by L*, C * , h, where L * represents lightness, C * represents chroma, and h represents hue.
- the color values (L * , a * , and b* or L*, C*, and h) at various angles are obtained using a color measurement device.
- the color measurement database 302 includes all valid field measurements (color values) for a particular paint color (color code).
- the color measurements included in the database 302 for a particular color code includes all measurements taken by inspectors and all valid measurements received by the system 100,300 from customers.
- the color measurement data contained in the database 302 is used by the various processes 120,308,310,312,314,316 of the system 100,300.
- C. Customer and Solution Usage Database [0038]
- the customer and solution usage database 304 contains customer and solution request data gathered by the system 100,300.
- the customer and solution usage database may contain information regarding a particular customer, how many times the customer has used the system and what solutions he has requested.
- search routine 120 is used to search the composite solution database 118 and determine a paint or other color solution as a function of the solution request. Given the color code or paint identifier (as part of the solution request), the corresponding formulations and associated color values are retrieved from the composite solution database 118.
- the formulations may be compared with the color measurements received from the operator 106 in the variant determination process 314 (see below). If a match is found, then the solution is sent to the operator 106 via the customer interface 306. If no match is found, then the solution creation process 308 (see below) attempts to derive a new formulation or adjust an existing formulation. If an acceptable solution is derived, then the derived solution is sent to the operator 106 via the customer interface 306. Otherwise, the operator 106 is informed that no solution exists. [0043] B. Derived Tolerances Process 316
- differential color values e.g., ⁇ L * , ⁇ C * , ⁇ H * .
- the derived tolerances process 316 is embodied in a neural network.
- the neural network is trained using the color values (L*,C*,h) for each formulation of each color and the differential color values from all acceptable measurements.
- the color values of the solution from the composite solution database 118 and the color measurement data taken from the subject part 108 form the input to the neural network.
- the output of the neural network is whether or not the color solution is acceptable.
- the neural network is a feed-forward, back propagation neural network.
- One such neural network is disclosed in commonly assigned US Patent Application Serial No. 09/874,699, (BASF Docket: IN-5458; Attorney Docket No. 65,241-008), filed concurrently with the present application, which is hereby incorporated by reference.
- the quality control analysis process 310 ensures that the data contained in the solution request is accurate. In other words, the solution request is analyzed for inconsistencies. [0049] D. Solution Creation Process 308
- the solution creation process 308 attempts to either create a new solution given the customer's color measurement value or adjust an existing formulation contained in the composite solution database 118 using artificial intelligence methods.
- One such system is described in commonly assigned and pending US Patent Applications Serial Nos. 09/779,101 filed February 7, 2001 (BASF Docket: IN-5393A) and 09/778,819 filed February 7, 2001 (BASF Docket: IN-5393B), both of which are incorporated herein by reference.
- the color formula conversion process 312 is utilized to convert color formulations between various paint, dye or colorant lines. Said process can be used to create needed solutions or starting points for the solution creation process 308.
- the formula conversion process 312 may be embodied in an artificial neural network.
- the variant determination process 308 may be used to select from the plurality of color solutions contained in the composite solution database 118
- the measurements received from the customer do not necessarily need to go through the variant determination process before being delivered to the customer.
- the variant determination process is run after the customer's initial need is met, i.e., the customer receives a solution.
- the variant determination is a cluster analysis of the measurements. There are several reasons for performing this analysis including the following:
- the variant determination process 308 compares the formulations with the color measurements of the part 108.
- the variant determination process is accomplished using artificial intelligence techniques.
- the variant determination process includes a self-organizing map (SOM) neural network (not shown).
