The foils stampping is all over the place on this issue
Why all this talk about
foil stamping?
The stamp was a combination print 4 colours offset/litho and
1 colour
(silver) engraved.Foil printing did not exist back in 1979, at least not on
Canadian stamps.
For this stamp the engraver cut deep and wide into the die
which caused the lettering of Canada and the value to be
raised much more than lets say "normal" line engraving.
Therefore when the the plate was forced against the paper
and the ink was sucked out of the grooves and deposited
in lumps on the paper.
