Sažetak
In this paper we investigate commercial 4-beam laser diode array with 830 nm laser. Experiment was performed on HP Indigo series 1000 machine. Controlled variation of the output laser power from 1 μW/mA to 12 μW/mA generates different sizes of screen elements on photoconductor. The results have been processed colorimetrically and with defining of colour difference CIE LAB ΔE. Measurements demonstrate that gamut space ΔV doesn’t change with variation of output laser power. Change of CMYK colors (solid tone) is negligible and 50% screen tone value experience up to ten times larger change of hue. Deviation of geometrical parameters of printed elements rises with enhancement of output laser power
