Besides numerous small sketches illustrating the various technical
processes, Eli Ponsaing's book ("Photopolymergravure: A New Method",
Copenhagen: Borgen, 1995 (ISBN 87-21-00396-3)) contains one original
(intaglio) photopolymergravure print and eight stochastic raster offset
reproductions of such gravures.
The process described in this book, and in my previous communications, is
the intaglio one. Earlier I just mentioned that the photopolymer material
_normally_, i.e., in industrial use, is employed for high-relief printing.
