Talk:Blueprint

Does a blueprint means a project too??. Does blueprint used for a service design to?as a service mapping?

Is there a very specific reason why BLUE was used? Or was it just randomly chosen?

Blueprint

What does zoning means in blueprint reading?

What is the significance of the blue print? How did it change the lives of people?

blueprint in popular culture?

should we add this as a section? maybe have a link to looney tunes ie. Wile E. Coyote and his love of all things acme with their crazy blueprints... just a thought.

I think this would be a good idea. 198.152.12.67 14:18, 27 July 2006 (UTC)[reply]

Can't say I see much relevance. -- Solipsist 15:43, 28 July 2006 (UTC)[reply]

Connection to technical drawing

The article explains blueprint as a printing process, and says that it is used for engineering drawings, but it doesn't explain why. Why was the blueprint process so popular for engineering drawings? Alf Boggis 09:52, 28 July 2006 (UTC)[reply]

Its a good question. I vaguely recall hearing that they used to be one of the only reproduction techniques that didn't risk changing the scale of the drawing slightly. But someone else probably knows the history better. -- Solipsist 15:43, 28 July 2006 (UTC)[reply]

It was popular mainly because it was relatively inexpensive to produce large-scale copies. Silver-based ( 'classic') photographic contact-printing duplicating systems were comparably prohibitive in cost. --Rxke 09:59, 6 September 2006 (UTC)[reply]

I was trained as a draftsperson at a very old school technical high school. We had to draft by hand and make our own blueprints, before we could use a computer. During that training we were told that since blueprints were a type of contact print they would always be dimensionally identical to the original. There would be no stretching, warping, or scaling. This is very important because the point of a blueprint is to have a copy that you can take measurements off of. We were told to never take measurements off of a photocopy because they do stretch and distort images (this was in the early '90s, and photocopiers have gotten better now.)67.2.152.163 (talk) 03:05, 23 January 2011 (UTC)[reply]

The colloquial usage of blueprint to refer to Technical drawing should be mentioned in this article, but the meaning in the article should be consistent with it's usage in the industry and restricted to the blueprint process and its results. Unless there is objection, I will adjust the article accordinlgy.--Jrsnbarn 15:53, 16 March 2007 (UTC)[reply]

BLUE PRINT addition to page

The reference to the car parts manufacturer should not appear on this page. If anywhere, it belongs in the disambig page - there is no relevence to this particular usage of the word blueprint. Just having the "same" name does not mean it belongs here...

A relic of the past???

It's inaccurate to portray blueprints as having been antiquated by the 1940's when other methods of reproduction arose-- many firms used blueprints well into the era of CAD and cheap computer technology. Lequis (talk) 02:25, 13 June 2009 (UTC)[reply]

Gripe and comment

I came here to find out when blueprint was first used. It could have been invented by the Romans, but probably wasn't. A description of the process is required. That requires the coated chemistry, the three day life of coated paper, the daylight frame and wash off of chemicals from the white areas. I will see what I can find. It's industrial use should be researched and described. It was essential for the industrial revolution. Manufactured articles were designed and then made in workshops from a copy of drawing(s) supplied. A steam engine was completely defined by just one drawing. The skyscraper revolution depended on blueprints. Diazo, or whiteprint, took over from 1935. Reg nim (talk) 21:30, 12 January 2011 (UTC)[reply]
