Abstract

Patente de Invenção: <B>"MéTODOS E APARELHOS PARA A CALIBRAçãO E A VERIFICAçãO DE COR''<D>. Métodos e aparelhos para a calibração de um instrumento de medição de cor com um padrão de cor e para a verificação do padrão de cor e da calibração são providos. Um método inclui a provisão de um padrão de cor que tem uma superfície com pelo menos duas cores diferentes (preferencialmente dispostas para uma medição de cor simultânea), a calibração do instrumento, e a verificação de o referido padrão de cor ser um padrão de cor autorizado de uma especificação predeterminada e de a calibração do instrumento de medição de cor ter atingido os resultados especificados predeterminados. Alguns dos métodos e dos aparelhos providos usam uma porção fotossensível do padrão de cor que muda de cor de uma forma conhecida quando exposta a uma dose predeterminada de luz. Vários padrões de cor para uso com esta invenção são providos.Invention Patent: <B> "METHODS AND APPARATUS FOR COLOR CALIBRATION AND VERIFICATION '' <D>. Methods and apparatus for calibrating a color measurement instrument with a color standard and for checking the color standard color and calibration are provided. One method includes providing a color standard that has a surface with at least two different colors (preferably arranged for a simultaneous color measurement), calibrating the instrument, and checking that standard of color is an authorized color standard of a predetermined specification and the calibration of the color measurement instrument has achieved the predetermined specified results.Some of the methods and apparatus provided use a photosensitive portion of the color pattern that changes color in a known shape when exposed to a predetermined dose of light Various color patterns for use with this invention are provided.
