RE: Photogravure and Inkjet

A mechanized subspecies used to appear regularly as the rotogravure section of the Sunday papers in the thirties and forties. Usually printed in sepia/browntone, it was a fixture of the society pages: "and you'll find that you're in the rotogravure..." (A buck if you can name the song. Canadian buck). Photogravure was a feature of the most elaborate series on photography ever published in the US, the ten-volume *Complete Photographer* edited by Willard Morgan, 1940-43. Each volume contained several photogravure sections, each with up to a dozen illustrations, many by the great B&W photographers of the day (and the past as well). It was/is truly a wonderful way to reproduce tones, but Lenswork's sneering de haut en bas tone with respect to ink jet prints, and the implication that only a few little old clockmakers can print photogravure is pretentious and silly. I've seen many ink-jet prints from this very company of printers that equalled Photogravure. PG was dethroned by duotone printing after the war, as tastes shifted to more open midtone- and high value-reproduction rather than the rich but dark low values of photogravure. Incidentially, if you think you have some of the older photogravure repros in your collections, a loupe will discover the tiny square boxes that contain and transfer the ink and diagnose the process. I don't know what's become of the process these days. Perhaps Ernst can comment. Bob Bollini > > I'd like to understand just how the photogravure varies the tones.

Very bizarre picture as an example of PG by the way. Thanks for the link. Very interesting although his explainations and constant referrences to other printing methods I don't understand make it a bit difficult. I do get from it that the ink density in the print is controled by the depth of the acid etching. Martin
