- Jul 11, 2011While Gerald’s contributions to the Wikipedia listing on letterpress can be readily detected as far as his interests and knowledge lie, some of the other stuff is of dubious value. As an example, the text under Industrial-scale use in the 20th Century uses the term oscillating for what I assume was a flat bed cylinder press and then attempts to describe a stereotype plate used on rotary newspaper presses and completely ignores any other rotary press used in both sheet fed and web fed letterpress presses that dominated 60 or more years of letterpress work that used plates other than stereotypes, mainly electrotypes, and also included photopolymer. A sketchy and poorly done listing. The video cited as one of three examples of letterpress is a really poor choice http://www.youtube.com/watch?v=YX7QBE3nYVY, and while maybe something is better than nothing, the entire letterpress listing despite Gerald’s contributions is lacking in overall information in my opinion. And no, I have no interest in adding to the listing—I think Wikipedia is my next to last choice for reliable information.FritzFrom: Gerald LangeSent: Monday, July 11, 2011 12:03 AMSubject: [PPLetterpress] Re: COMMENTS ON LEAD OXIDEâ€¦..AND OTHER PRINT SHOP TOXINS
Oh indeed. Totally suspect. Here is the Wikepedia reference on letterpress.
How self serving is this? If you have been round and about you can even identify the me me culprits.

It actually provides preservative qualities to the paint. And yes, Mr. Gutenberg used quite a bit of it in his ink, the formula for which he took to his grave. Modern technology though has figured out a way to identify everything he ever printed simply because of the molecular composition of the ink used. The brilliant blacks of every Gutenberg Bible I have ever seen (two) is quite amazing, some five and a half centuries after. He, of course, did not invent the formula but rather appropriated it for better use from some metal workers in Flanders. He was a genius at appropriating.
