F\u00e4rgm\u00e4tning anv\u00e4nds f\u00f6r att best\u00e4mma den exakta f\u00e4rgplatsen<\/a> f\u00f6r en f\u00e4rg i ett f\u00e4rgsystem<\/a>.<\/p>\n

Det finns tre f\u00f6rfaranden:<\/p>\n

Metoden med tre intervall (tristimulusmetoden):
\n<\/strong>A F\u00e4rgm\u00e4tare<\/a> lyser en intern ljusk\u00e4lla p\u00e5 f\u00e4rgprovets yta. Det reflekterade ljuset passerar genom tre filter: r\u00f6tt, gr\u00f6nt och bl\u00e5tt, vilket best\u00e4mmer intensiteten hos dessa f\u00e4rgkomponenter.<\/p>\n

Spektrala metoder:
\n<\/strong>A Spektrofotometer<\/a> fungerar p\u00e5 ett mycket liknande s\u00e4tt - men har inte bara tre utan 31 filter som m\u00e4ter 31 olika v\u00e5gl\u00e4ngder av ljus. Detta g\u00f6r spektralmetoden till en av de b\u00e4sta metoderna f\u00f6r f\u00e4rgm\u00e4tning.<\/p>\n

F\u00f6rfarande f\u00f6r likabehandling:
\n<\/strong>H\u00e4r anv\u00e4nds en tref\u00e4rgsm\u00e4tare (eller \u00f6gat) f\u00f6r att j\u00e4mf\u00f6ra f\u00e4rgprovet med standardf\u00e4rgprover tills proverna \u00e4r identiska enligt observat\u00f6rens bed\u00f6mning. Detta \u00e4r dock en subjektiv bed\u00f6mning av observat\u00f6ren, varf\u00f6r andra metoder f\u00f6r f\u00e4rgm\u00e4tning \u00e4r att f\u00f6redra i praktiken.<\/p>","protected":false},"excerpt":{"rendered":"
