Gum bichromate[edit]

How about merging this article with Gum bichromate plus a redirect from "gumprint"? --Einemnet 07:43, 5 November 2007 (UTC)

Two main issues. Firstly the Gum bichronate process and Gum printing are different in that in the first, coloured material is included in the gelatine bichromate mix so that after exposure and "development" a single coloured print is obtained. In gum printing however the process makes a negative in relief which is then used to make multiple copies using a printing method similar to lithography - unfortunately the text of the Gum printing article confuses the two processes making them sound as if they are the same. I will try and edit a little more clarity into the article. Velela 22:57, 5 November 2007 (UTC)

A further issue is that much of the text of the Gum bichromate article really belongs in Wikibooks and not here - all the recipe and methods stuff for example. Velela 23:03, 5 November 2007 (UTC)
