Re: Photogravure question

There is no question that wonderfull prints are being done on photo-polymer
plates. There is no way to see the difference between copper plate
photogravure and acrylic plate intaglio in photos of the prints (let alone
web images). The actual 3 dimentional ink from a copper plate uses all the
best features of intaglio. Photogravure is very complex and not for
everyone, but it is not the same as photo-polymer intaglio. There's lots of
room for both but lets be clear in our terminology.
