20.500.12556/RUL-112 Primerjava merjenja barve s kolorimetrom in z optičnim čitalcem diplomsko delo (visokošolski strokovni študij) Comparison of colour measurments with a colorimeter and an optical reader graduation thesis (higher professional studies) S kolorimetrom in z optičnim čitalcem smo spremljali spremembe barv lesnih premazov zaradi naravnega staranja oz. izpostavitve vremenskim vplivom. 9 različnih vrst premazov smo nanesli na vzorce rdečega bora in jih izpostavili vremenskim vplivom. Meritve barve smo izvedli pred, med in po izpostavitvi. Podatke, pridobljene z različnima metodama merjenja (s kolorimetrom in optičnim čitalcem oz. skenerjem), smo medsebojno primerjali. Ugotovili smo, da se vrednosti /L* glede na način merjenja med seboj signifikantno ne razlikujejo. Vsi drugi parametri barv, spremenjenih zaradi izpostavitve vremenu, /a*, /b* in /E* pa so predvsem pri transparentnih premazih bistveno odvisni od načina merjenja. Changes of various wood coating colours due to natural ageing (exposure to weather) were measured with 2 different instruments: a colorimeter and an optical scanner. 9 different typs of coating, applied to Scots pine wood samples were exposed to the influence of natural weather. Measurements of colour were carried out before, between and after the exposure. The results obtained using 2 different methods (a colorimeter and an optical scanner) were compared and statistically analysed. The /L* values were found out not to be dependent on the measurment method. On the other hand, all other parameters indicating a change of colour (/a*, /b* and /E*) due to ageing were significantly influenced by the measurment method, especially at transparent wood coatings. površinski premazi merjenje barve kolorimeter optični čitalec surface coating measurment colorimeter optical scanner true false false [L.
