    摘要: The hydrophilic properties of a printing-machine roller are adjusted with a coating applied on an outer surface of its cylindrical body. The coating contains at least 45% by weight of pure silicon, or it is formed exclusively of chemically pure silicon. The coating is between 0.2 and 2 mm thick and its surface roughness R.sub.z is no more than 5 .mu.m.
