Definitions

  • the present invention relates to color physics, and more particularly, to a system for accurately, communicating color needs and supplies over an electronic media.
  • colors are more complex. Although simple color descriptions, such as red or blue, give a general idea of the color, the foregoing are too imprecise in many commercial contexts. Where a precise color description is required, colors are communicated by- means of physical samples which are examined by the parties. The transferring of a physical sample from one party to another can greatly increase the time required to complete a transaction, even where the physical sample is sent by an overnight courier.
  • a common practice in the textile industry is the use of swatch booklets.
  • Dyestuff suppliers provide a booklet of sample fabrics that have been dyed by each of the supplier's available dyes to various purchasers.
  • the dyestuff user may view the swatch showing the combination nearest to that desired.
  • Providing the purchasers with swatch booklets permits faster recipe creation and, therefore, improved customer service.
  • Swatch booklets are costly to produce and are not susceptible to copying, thereby increasing marginal costs .
  • the dyestuff supplier must distribute the swatch booklets to each of their customers and potential customers. In many cases, the customers are located all around the world, and such distribution can entail a considerable lag time. Furthermore, the swatch booklets must be updated or replaced with each additional dye that is created. Due to the expense and lag times associated with the swatch booklets, dyestuff users (dyehouses) are often discouraged to make changes in their dyes. Swatches may also be used for the sale of colored products, such as fabrics, or yarns. When a purchaser wishes : to purchase a particular color of fabric or yarn, the -purchaser simply identifies the particular color from the swatch book and notifies the colored product manufacturer (fabric or yarn dyehouse) .
  • a color can be communicated from one party to another by optically scanning a sample of the color and electronically transmitting a digital representation of the color over a communication medium to a computer monitor or a printer.
  • the transfer of the digital representation is almost instantaneous and use. of the internet or public switched telephone network, permits transfer to virtually anywhere in the world.
  • the digital representation must be in accordance to a predetermined standard that is . understood by both the optical scanner and the output device. Where the optical scanner and the output device are separated by vast distances, it is possible that the optical scanner and the output device use different standards.
  • the digital representation that is generated is based on lighting, the substrate that is colored, as well as the calibration parameters of the optical scanner. The appearance of the color on the output device is based on calibration parameters of the output device.
  • the CIE 1976 L*a*b* color space is the most widely used method for measuring object color.
  • the CIE 1976 L*a*b* is a mathematical model describing color sensations and is based on the color describing theory of opponent colors .
  • the method of describing colors by an opponent-type system follows the idea that somewhere between the eye and brain, information from cone receptors in the eye gets coded into light-dark, red-green, and yellow-blue signals.
  • colors can be considered as combinations of red and yellow, red and blue, green and yellow, and green and blue.
  • One advantage of the CIE 1976 L*a*b* standard is that differences between colors agree consistently well with visual perceptions of the differences .
  • a spectrophotometer is a device which exposes a colored substrate to a series of lights with differing predetermined wavelengths and measures the degree of reflectance for each wavelength. Accordingly, the spectrophotometer measures the "true" color, as opposed to the perceived color.
  • the present invention is directed to a system and method for an on-line color physics web site which defines a standardized color universe for defining all of the colors in the visible spectrum.
  • a spectrophotometer at the client computer under the control of a software program at a server computer creates a digital representation of an input coloring substance as it would appear in known concentrations on known substrates or a colored product.
  • a data structure at the server computer stores the digital representation and is accessible worldwide.

  • FIGURE 2 is a block diagram of a high-speed communication network configured to facilitate the color exchange
  • FIGURE 3 is a block diagram of a color space
  • FIGURE 4 is a block diagram of a system for inputting the color of a sample
  • FIGURE 5 is a block diagram of an exemplary histogram
  • FIGURE 6 is a block diagram of the color exchange system configured to facilitate the sale and purchase of coloring substances and colored products.
  • FIGURE 7 is a flow diagram describing the operation of the color exchange.
  • the color exchange 100 links members of a colored products supply chain.
  • Members of the colored products supply chain include producers 101 of dyes, paints, and other substances used for coloring (now referred to as coloring substances), product manufacturers 102 which use the coloring substances to color various products (now referred to as colored products) , colored products assemblers 103 who assemble the colored products into end products, and any number of middlepersons 104 leading to retailers.
  • Coloring substance producers 101 can include, for example, dye stuff warehouses, and paint makers.
  • Colored product manufacturers 102 can include, for example, a fabric dyer, a dyehouse, an auto parts maker, and a molded plastic manufacturers.
  • a colored products assembler 103 can include, for example, garment manufacturers and auto manufacturers.
  • a seller which can include any of the foregoing parties, can communicate their- inventory of available coloring substances or colored products for sale.
  • a buyer which can also include any other foregoing parties, can communicate the coloring substances or coloring products which are sought for purchase.
  • the information . regarding the colors sought and for sale is classified, and catalogued within a predetermined color measurement and description standard known as a color space. Accordingly, buyers seeking to buy and sellers seeking to sell a particular coloring substance or colored product can instantaneously communicate the color and locate buyers and sellers to secure a transaction.
  • the color exchange 100 alleviates substantial transaction costs. For example, the sellers are alleviated from costs associated with dissemination of information of the goods that sellers have to sell. The buyers are alleviated from having to contact each seller to review their inventory. By reducing transaction costs, the color exchange 100 increases the liquidity of the market for the coloring substances. To further increase ' the liquidity of the market for the coloring substances and colored products, high speed communication must occur between the buyers and sellers and the color exchange 100.
  • the computer network 200 comprises at least one server 205 and any number of client computers 210.
  • a server 205 is a computer which centralizes various resources for usage by any number of client computers 210.
  • the resources centralized by the server 205 can include, for example, application program 215 and databases 220. Additionally, the server 205 can provision email service for the client computers 210.

  • the client computers 210 access the centralized resources by establishing an input/output connection with the server 205, known as a client/server connection.
  • the client/server connection is established by means of a communication channel 225.
  • the communication channel 225 includes any combination of communication media, such as, but not limited to, a coaxial cable, a fiber optic link, a wireless radio link, or a connection within the public switched telephone network.
  • Another type of communication media is known as the Internet.
  • the Internet comprises any number of local area networks (LANs) and wide area networks (WANs), from corporations, educational ;institutions, the military, and government agencies from around the world, connected together by means of high capacity data links.

  • Implementation in the foregoing manner allows for instantaneous communication between the buyers and sellers and the color exchange 100.
  • the centralized nature of server 205 permits storage of information regarding the sellers' inventories and the buyers' demands in the remotely accessible database 220.
  • the server 205 is preferably directly connected to the internet, and at least a major component of the communication channel comprises the internet, thereby permitting access from client computers 210 located virtually anywhere in the, world.
  • the high speed communication network 200 permits rapid and efficient communication between buyers and sellers. Notwithstanding .
  • a color products assembler 103 such as a garment manufacturer 103, may seek to purchase a set of zippers and sewing threads from colored . products manufacturers 102, to apply to a certain material to make a garment .
  • the garment manufacturer 103 must purchase zippers and sewing threads that are matching within a certain small degree of tolerance to the color of the material.
  • the garment manufacturer 103 In order for the garment manufacturer 103 to approve and purchase such zippers and sewing threads, the garment manufacturer 103 must be able to communicate the color sought and understand the color of the zippers and sewing threads produced by the colored products manufacturer 102.
  • FIGURE 3 there is illustrated a block diagram of a color space, referenced generally by the numeral designation 300, for describing a color.
  • the most widely used color space 300 is known as the CIE 1976 L*a*b* color space.
  • the CIE 1976 L*a*b* is a mathematical model describing color sensations and is based on the color describing theory of opponent colors. The concept follows that colors can be considered as combinations of red and green, yellow and blue, and black and white.
  • One advantage of the CIE 1976 Lab is that the differences between colors agree consistently well with visual perceptions of the differences. A given color is associated with a series of parametric measurements measuring red/green factor, blue/yellow factor, and black/white factor.
  • the information regarding a seller's inventory or a buyer's demands can be communicated using the foregoing color space 300. Additionally, this information can be catalogued and stored as records in a data structure emulating the color space 300 in database 220.

  • the spectrophotometer- 405 conducts wavelength reflection tests on the sample 402. The wavelength reflection tests on the sample 402 produce results that are indicative of the color, independent of surrounding lighting. Additionally, if the spectrophotometer conducts wavelength reflection tests separately on a colored sample and an uncolored sample of a substrate, the effects of the substrate can be mathematically separated to give the results for the effect of the coloring substance alone .
  • the histogram 500 includes a horizontal axis 505 measuring the wavelengths 510 of light .
