Not to split hairs too finely, but the "etching" is performed by the
water rinse (sometimes aided by a soft bristle brush), the plate is
hardened by exposure to light... again a similarity to photogravure,
not a difference. Here water replaces the acid in creating the pits of
the plate.

Polymer gravure IS an intaglio process - it produces an incised plate
and
the ink is applied just as in an etching. The difference is that the
plate
is etched by light rather than by acid, so in a way it's a really
photographic process.

I don't discount that it is possible to pull some very nice prints
from photopolymer plates. I would question if any process should be
called Gravure unless it is an intaglio printing process. Calling a
process, which is not an intaglio process, "Photogravure" is
misleading although calling it such would have some "retro" appeal
(good marketing hook). If it is possible to use photopolymer plates
so as to produce a plate that prints in the same manner as a Gravure
plate then I will have no problem calling it a Gravure process;
otherwise the terminology is just plain wrong.
