(57) The method initially entails the erosion etching of a metal die (1), thus obtaining
recesses (2,3,5,6) in which thermosetting plastic material is introduced to fill the
die. Plastic material is then selectively removed from at least one of the previously
filled recesses (2,3,5,6), and more thermosetting plastic material of a different
color is subsequently introduced therein. The steps of introduction and removal of
plastic material of different colors in other recesses can be repeated. The recesses
(2,3,5,6) having thus been filled with the plastic material of the desired color in
the desired combination, more thermosetting plastic material is spread on the filled
die (1), coupling thereon a sheet of synthetic fiber which constitutes a support for
the plastic material. The subsequent steps entail the pre-heating of the die in an
oven and its final heating in a heated press. The cooling of the die (1) then takes
place in the press and at the end of said step the resulting sheet and/or label is
removed from the die.
