How is a Woodburytype different than a photogravure? They seem related but I can find no mention of the other on either page. Ckrfriedman (talk) 10:46, 7 April 2020 (UTC)[reply]

Weird "NEWS" section

[edit]

I've moved the following from the article to here because it doesn't belong in an encyclopedia, at least in its current form:

===NEWS: Autotype G35 and G25 Gelatin Pigment Paper (tissue) Discontinued===


In August of 2009, Macdermid Autotype, the last manufacturer of the gelatin pigment paper (tissue) needed to make traditional copper plate photogravure, announced that the product would no longer be manufactured. The photogravure community reacted immediately. Now there are practitioners/suppliers who are currently working on plans to take over the manufacture of the material for use by the photogravure/artist community rather than supply the commercial/industrial community which seems to have moved on.

I think the "Alternatives" section is supposed to go with this "news" section, but I've left the "Alternatives" section as-is because it seems encyclopedic and not written in an inappropriate style. It may need to be given some context to tie it into the rest of the article, though. — Saxifrage 00:34, 19 November 2009 (UTC)[reply]


Polymer Plate section should probably removed

[edit]

The below section on "polymer photogravure" should probably removed/moved. The sentence, "Some feel......polymer coating compromises quality." is misleading and borders on hearsay. There is no dispute over this - polymer plates cannot hold the same amount of quality/information that a photogravure plate can. Polymer plates simulate a full scale of values (light to gray to black) by varying the density of dots that are all etched to the same depth (much in the same way that a halftone screen simulates a full scale of values). Photogravure plates reproduce images using both variations in the density and depth of extremely fine dots - allowing for a full range of true values on the same level as silver gelatin prints. This fact, and the fact that the section lists names of polymer plate manufacturers makes the section seem suspiciously like an advertisement. The type of printing that the section describes using polymer plates for is commonly referred to as "photo etching" and would not easily be mistaken for a photogravure.

"Photo-polymergravure / Polymer Photogravure Photopolymer plates, usually used for relief and letterpress printing, can be used to make photogravure plates. These polymer plates, when developed, are a hard plastic, which allows for fewer impressions to be made. Some feel that they rival the quality of traditional copper plate photogravure, while others find that the lack of differential depth in the polymer coating compromises quality."

I agree completely with Dirtmcguinness' comment -- the polymer section should be removed entirely, for the reasons stated: polymer is not gravure, there is no etching and therefore no differential depth of etching. Differential depth of etching is the distinctive basis of photogravure. Also there is no reason to list the makers of polymer plates here. -- Kamprint — Preceding unsigned comment added by Kamprint (talkcontribs) 02:08, 8 August 2014 (UTC)[reply]

Photogravure is Photo Engraving. Photopolymer is not. Artmarc1 (talk) 22:41, 12 April 2018 (UTC)[reply]
