Keeping anilox rolls clean is one of key factors of quality printing. If anilox cell is plugged with dirt, dried ink or varnish, it is hard to achieve printing of high quality. Plugged cells of anilox roll decrease ink transfer level of anilox roll, i.e. reduce delivery amount of ink and varnish. When regular cleaning products do not provide desired results, "Pratex" company offers laser-cleaning service ofanilox rolls and sleeves. Such service does not take a lot of time (usually within 3 working days) and what is more important, it is much more gentle to surface compared to ultrasonic cleaning. Unfocused laser beam removes all organic element compounds, without damaging cells.
