A printing and/or varnishing machine having a plurality of sheet-guiding
cylinders in which at least one of the cylinders has an outer detachable
packing which has enhanced ink repellent characteristics and which
significantly reduces wear. The packing has a layered structure which
includes a flexible backing material 12, the underside of which is
assigned to the base body of the sheet-guiding cylinder 3, a coating 13
of molybdenum or tungsten carbide/cobalt which is adhesively applied to
the upper side of the backing material 12, and a sealing layer 14 of a
material made from the group of polysiloxanes which is adhesively applied
to the upper side of the coating 13. The side of the packings 5, 6 which
faces the material to be printed has a surface profile consisting of
cones 18 with rounded tips 16 for reduced sheet contact.
