Kurzbeschreibung (Abstract)
This work investigates wetting properties of thermo and waterless printing plates commonly used in offset lithography with the goal to analyse the potential of a new printing plate making process by surface laser structuring. Measurements of the surface free energy of thermo, waterless and laser-structured aluminum samples are presented and compared. Also, the surface tension of fountain solutions and inks are measured. Laser-structured aluminum samples reached a comparable surface free energy like the waterless offset printing plate. With the help of microscopic measurement, the topography of the printing plates and the laser-structured aluminum samples were evaluated. In addition, wetting envelopes are presented which can be used to predict the wetting of a substrate with a liquid whose surface tension is known.
