Abstract

The paper describes a variant of multi-illuminant strategy of colour match prediction calculation for the cases of CMC (l:c) and CIE94 colour differences. This strategy tries to minimize the colour differences (against a given standard) under several different illuminants. In case when a given standard, using the usual single-illuminant matching strategy, can not be matched non-metamerically by the colorants available, the multi-illuminant matching strategy tries to produce a more acceptable match by balancing the colour differences under several different illuminants. The theoretical concepts are illustrated by the colorimetric data of the corresponding laboratory samples produced by either strategy. The multi-illuminant-strategy regularly produced lower metamerism than the single-illuminant strategy did.

Secondary title: Formulacija receptura s najmanjom metamerijom
Secondary abstract: Opisana je inačica »višesvjetlosne« strategije za predviđanje receptura za bojanje uz pretpostavku da su razlike u boji opisane s tzv. CMC (l:c) i CIE 94 jednadžbama. Ova strategija pokušava za različita osvjetljenja istovremeno smanjiti razlike u boji u odnosu na zadani standard. U slučajevima kada se raspoloživa bojila primjenom »jednosvjetlosne« strategije ne daju nemetamerijski složiti u recepturu usporedivu sa zadanim standardom, »višesvjetlosna« strategija, uravnoteživanjem razlika u boji pod različitim osvjetljenjima, nudi prihvatljivu formulaciju. Obje su strategije objašnjene i ilustrirane s kolorimetrijskim podacima niza laboratorijskih uzoraka, pri čemu je pokazano da »višesvjetlosna« strategija u pravilu daje manje metamerijske recepture.
