Abstract (en)
[origin: EP0605074A1] An ink washing device, for use in a printing machine having a deposit roller (9) with a variable luminance outer surface. The washing device includes a blade (13) disposed adjacent to the deposit roller (9), for removing excess deposit of ink on the outer surface of the deposit roller (9), thus causing its luminance to vary. A luminance sensor (14) detects changes in the luminance of the outer surface. The washing operation is interrupted or continued based on the detected luminance changes.
