Primerjava vrednotenja barvnih razlik lesnih premazov s kolorimetrom in z vizualnim zaznavanjem : diplomski projekt = Comparison of evaluation colour differences of wood coatings with colorimeter and visual perception : B. Sc. thesisDemšar, BorisUgotavljali smo razlike med občutljivostjo vizualnega zaznavanja barvnih razlik in numeričnega vrednotenja, na barvno različnih vzorcih. Pripravili smo 12 različnih parov površinskih sistemov- en ... vzorec od vsakega para smo shranili, drugega pa obsevali z UV svetlobo, da bi povečali razliko med barvama obeh vzorcev v paru. Vzorci so se med seboj razlikovali po vrsti in namembnosti podlage, premaznem sistemu, teksturi podlage ter dimenziji. Po vsakem obsevanju z UV svetlobo smo med seboj primerjali barvi vzorcev posameznega para. Anketirali smo vedno isti letnik študentov- ti so na anketnih lističih označili, kolikšna je barvna razlika, če je le-ta opazna. Po vsakem obsevanju pa smo barvo izmerili tudi s kolorimetrom, ter nato izračunali barvne razlike. Večinoma so anketiranci zaznali razliko barve le v primerih, ko je numerično vrednotena razlika barve %E* imela vrednosti v območju med 0,5 in 1,0. V nekaterih primerih so anketiranci spremembo barve komaj zaznali šele pri vrednostih %E* nad 3,0. To kaže, da sta zmožnost čutnega zaznavanja barvnih razlik in s kolorimetrom izmerjenih vrednosti %E* med seboj le šibko povezani, saj na čutno zaznavo barvne razlike vplivajo različne lastnosti površine, kot sta npr. sijaj in teksturaType of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
