Abstract

Abstract The present invention discloses a method and system for formulating a color match. In the present invention, there is provided a method and system for formulating a color match from a set of previously used color formulations. The present invention includes reading the color spectrum of a standard. After obtaining the color spectrum, the set of previously used color formulations are searched for a set of color formulas that approximates the color of the standard. Next, a color formula is selected from the set of color formulas that best matches the color of the standard. Then a test batch is made with the color formula having the best match and examined for its acceptability. The color formula with the best match is adapted if the formula is unacceptable. The adaptation includes at least one of manual adjusting color loadings of the color formula, synthesizing a match with the color standard, or searching through the set of previously used color formulations until there is an acceptable match. If the adapted color formula does not match the color of the standard, then the formula is further adapted until there is an acceptable match.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 185 words
A computer-implemented method for formulating a color match from a set of previously used color formulations, the method comprising the steps of: reading a color spectrum of a standard; searching the set of previously used color formulations for a set of color formulas that approximates the color of the standard; determining from the set of color formulas a color formula that best matches the color of the standard; examining a test batch made from the color formula having the best match and determining the acceptability of the formula; adapting the color formula of the test batch to the color of the standard if the formula is unacceptable, the adapting including at least one of manual adjusting color loadings of the color formula, synthesizing a new match with the color standard by using new colorants and color loadings, or searching through the set of previously used color formulations until there is a more acceptable match; determining if the adapted color formula matches the color of the standard; and adapting the adapted color formula further until there is an acceptable match with the color of the standard.
Claim 2
Dependent Claim 185 words
A computer-implemented method for formulating a color match from a set of previously used color formulations, the method comprising the steps of: reading a color spectrum of a standard; searching the set of previously used color formulations for a set of color formulas that approximates the color of the standard; determining from the set of color formulas a color formula that best matches the color of the standard; examining a test batch made from the color formula having the best match and determining the acceptability of the formula; adapting the color formula of the test batch to the color of the standard if the formula is unacceptable, the adapting including at least one of manual adjusting color loadings of the color formula, synthesizing a new match with the color standard by using new colorants and color loadings, or searching through the set of previously used color formulations until there is a more acceptable match; determining if the adapted color formula matches the color of the standard; and adapting the adapted color formula further until there is an acceptable match with the color of the standard.
Claim 3
Dependent Claim 29 words
A computer-implemented method according to claim 1, further comprising the step of entering matching requirements for obtaining the set of color formulas that approximates the color of the standard.
Claim 4
Dependent Claim 20 words
A computer-implemented method according to claim 1, further comprising the step of making a standard with the adapted color formula.
Claim 5
Dependent Claim 19 words
A computer-implemented method according to claim 3, further comprising the step of reading the color spectrum of the standard.
Claim 6
Dependent Claim 28 words
A computer-implemented method according to claim 1, further comprising the step of storing the color formula having the acceptable match with the set of previously used color formulations.
Claim 7
Dependent Claim 32 words
A computer-implemented method according to claim 1, wherein the manual adjusting of color loadings comprises adjusting the relative ratios of the colorants and the loadings of the colorants in the color formula.
Claim 8
Dependent Claim 37 words
A computer-implemented method according to claim 1, wherein the synthesizing of a new match with the color standard comprises using a statistical analysis to determine new colorants and colorant loadings that most likely match the color standard.
Claim 9
Independent Claim 225 words
A system for formulating a color match from a set of previously used color formulations, the system comprising: a spectrophotometer for reading the color spectrum of a standard; and a processor for formulating a color match from the set of previously used color formulations to the color spectrum of the standard read from the spectrophotometer, the processor including means for searching the set of previously used color formulations for a set of color formulas that approximates the color of the standard; means for determining from the set of color formulas a color formula that best matches the color of the standard; means for examining a test batch made from the color formula having the best match and determining the acceptability of the formula; means for adapting the color formula of the test batch to the color of the standard if the formula is unacceptable, the adapting including at least one of manual adjusting color loadings of the color formula, synthesizing a new match with the color standard by using new colorants and color loadings, or searching through the set of previously used color formulations until there is a more acceptable match; means for ascertaining if the adapted color formula matches the color of the standard; and means for adjusting the color formula further until there is an acceptable match with the color of the standard.
Claim 10
Independent Claim 225 words
A system for formulating a color match from a set of previously used color formulations, the system comprising: a spectrophotometer for reading the color spectrum of a standard; and a processor for formulating a color match from the set of previously used color formulations to the color spectrum of the standard read from the spectrophotometer, the processor including means for searching the set of previously used color formulations for a set of color formulas that approximates the color of the standard; means for determining from the set of color formulas a color formula that best matches the color of the standard; means for examining a test batch made from the color formula having the best match and determining the acceptability of the formula; means for adapting the color formula of the test batch to the color of the standard if the formula is unacceptable, the adapting including at least one of manual adjusting color loadings of the color formula, synthesizing a new match with the color standard by using new colorants and color loadings, or searching through the set of previously used color formulations until there is a more acceptable match; means for ascertaining if the adapted color formula matches the color of the standard; and means for adjusting the color formula further until there is an acceptable match with the color of the standard.
