  • Publication number: 20190332254
    Abstract: A computer system for optimizing a coating formulation through a user interface processes spectrometric data through a probabilistic colorant analysis. The probabilistic colorant analysis generates a set of colorants that are each associated with a calculated probability that the associated colorant is present within a target coating. The system identifies a proposed group of colorants from within the set of colorants that are associated with the highest calculated probabilities of being present within the target coating. The system displays on a graphical user interface an indication of each colorant within the proposed group of colorants. The system receives input through one or more selectable interface elements that define a user-defined group of colorants selected from the proposed group of colorants. The system generates a coating formulation, wherein the coating formulation is generated from the user-defined group of colorants.

  • Publication number: 20190331591
    Abstract: A computer system for identifying coating texture effects initiates a set of colorant decision points. The colorant decision points identifying a probability that an effect pigment type is present within a target coating. The computer system calculates in parallel each colorant decision point within the set of colorant decision points. Each colorant decision point provides a probability that a different effect pigment type is present within the target coating. The computer system then calculates a set of final colorant probabilities. Each final colorant probability within the set of final colorant probabilities is calculated by combining a unique subset of probabilities calculated by the first set of colorant decision points. Additionally, each final colorant probability indicates a probability that an associated colorant is present within the target coating.

  • Publication number: 20190333246
    Abstract: A computer system for seeding a formulation engine receives spectrometric data from a target coating. The computer system processes the spectrometric data through a probabilistic colorant analysis. The probabilistic colorant analysis generates a set of colorants. Each colorant within the set of colorants is associated with a calculated probability that the associated colorant is present within the target coating. Additionally, the computer system adds at least a portion of the colorants within the set of colorants to a formulation engine. The portion of the colorants is added to the formulation engine in order of decreasing probability. Further, the computer system generates, from an output of the formulation engine, a coating formulation that is calculated to match the target coating within a predetermined qualitative threshold.
