The conventional method of printing using a pre-sensitized (PS) plate involves major problems in terms of consistency of quality and environmental impact. Among the specific problems with conventional PS printing using a dampening solution are that it does not deliver consistent quality; printing press operation is frequently interrupted to adjust the dampening solution; and the dampening solution contains isopropyl alcohol (IPA) and etching fluid, which are not conducive to environmental conservation.

To eliminate these problems, Toray has developed a printing system that uses silicone to replace the dampening solution. This revolutionary printing system realizes not only environmentally friendly operation and high quality printing but also improvements in productivity.
