Optical Examination of Paperboard Surfaces Exposed to Ageing at laboratory Conditions

Damir Modrić

Sažetak

Effects of simultaneous solar radiation and artificial ilumination uppon the various board samples at laboratory conditions have been examined. These effects have been observed during time, and thus ageing of samples has been examined. The samples are paperboards of differently treated surfaces. Relative reflection has been measured using spectrophotometer CS-3, CHROMA Sensor, Data Color and optical density using densitometer VIPTRONIC, VIPDENS 1000P.
