Roberta's answer Please excuse the pun, but Roberta is "spot on". In the end I called up an acquaintance of mine who works as a graphic artist and asked for an explanation of various terms, and he gave the same explanation as Roberta. So "verniciatura" is far from being the pleonastic word I thought it was. Roberta please would you submit your suggestion as an answer?

scrre-printing and spot varnishing are two different proceedings

Roberta Anderson Nov 4, 2010:

a varnish is applied (in this case through screenprinting) to areas of the cover to make them glossy or matt. Also called "spot varnishing" - It is important to retain the concept of "varnish" because screenprinting can also be used for other purposes - see http://www.graphicpointspa.it/serigrafia.html
