Svjetlosna postojanost naranđastih i ljubičastih ElektroInk otisaka

n production of high quality packaging reproductions of color based on multicolor printing process the EP machines can use six printing units, which except the CMYK process Ink contain two additional inks as well. Such a possibility has the HP Indigo machine which applies the liquid Electroink. In this paper, the durability of HP Indigo prints realized by using the original PANTONE colors (solid violet and solid orange) or the same violet and orange tones printed with raster mixing process colors (making double ink layer) were dealt with. The time period of aging (240 days) shows that results of color changes are sufficient. However colorimetric measuring observed the larger permanence of orange prints printed with the original PANTONE and violet ElectroInk prints printed with two layers (cyan and magenta).
