Abstract

On décrit un procédé au moyen duquel le temps pris pour confirmer une couleur suite à une requête de virage vers la fin du virage est réduit. Un spectrocolorimètre (201) situé côté confirmé lit une couleur de confirmation devant être confirmée, calcule, par exemple, les réflectances spectrales dans 16 à 32 points discontinus dans la bande de longueur d'onde visible comprise entre 380 et 780 nm (étape S101) et calcule les composantes trichromatiques (X, Y, Z) à partir des réflectances spectrales calculées (étape S102). Un terminal de communication (203) situé côté confirmé envoie les composantes trichromatiques (X, Y, Z) au côté confirmation par une ligne de communication (étape S103). Un terminal de communication (204) situé côté confirmation reçoit les composantes trichromatiques (X, Y, Z) puis une imprimante couleur (205) située côté confirmation reproduit la couleur de confirmation à partir des composantes trichromatiques (X, Y, Z) (étape S104).
