Elrepho is the paper industry’s own spectrophotometer. It measures colour, brightness, opacity and whiteness of paper, paperboard, tissue, pulp, coating inks and fillers. The visual appearance for a printed product is of crucial importance and is expensive to achieve. Elrepho automatically measures according to the conditions specified by the user, e.g. D65 illuminant, C illuminant, or a 420 nm cut-off filter.
