Abstract
A method for cleaning a rotating surface of a printing press cylinder or a rotating surface of a printing press roller, or a rotating surface of a print form or a transfer form arranged on a printing press cylinder within a printing unit includes the steps of: applying a liquid, water-based washing agent, containing at least 60% water and the rest at least surfactants, onto the surface to be cleaned within the printing unit; dissolving contaminations from the surface to be cleaned within the printing unit with the help of the washing agent and a cleaning device; and removing the dissolved contaminations from the surface to be cleaned within the printing unit, at least with the help of the cleaning device.
Claims19
A method for cleaning a surface of a transfer form arranged on a transfer cylinder of a printing press, the method comprising:
- applying a liquid, water-based washing agent comprising at least 60% water and the rest at least surfactants onto the surface;
- dissolving contaminations comprising ink residue and substrate debris from the surface with the washing agent and a cleaning device;
- and
- removing the dissolved contaminations from the surface at least with the cleaning device;
- wherein the cleaning device at least during the dissolving of the contaminations is pressed against the surface to be cleaned with a line pressure force such that the surface of a transfer form is elastically deformed between about 0.01 mm and about 0.20 mm.
A method for cleaning a rotating surface of a transfer form positioned on a transfer cylinder, comprising:
- providing a liquid, water-based washing agent and a cleaning device;
- heating the washing agent to a preselected temperature;
- applying the heated washing agent onto the cleaning device;
- pressing the cleaning device against the rotating surface of the transfer form with a line pressure force such that the surface of the transfer form is elastically deformed between about 0.01 mm and about 0.20 mm;
- dissolving contaminants comprising ink residue and substrate debris from the rotating surface of the transfer form using the washing agent applied onto the cleaning device;
- and
- removing the dissolved contaminants from the rotating surface of the transfer form using the cleaning device.
