Talk:Photocopying
From Academic Kids
what's the name for the copying method that makes copies with purple ink that smell of meths? UK school in the 80s used it before they got photocopiers. -- Tarquin 11:45 May 12, 2003 (UTC)
There were several, among them the Gestetner machine and the Ford-a-graph (sp?) machine, better known as the "forgeagraph". Ink was either purple or green, and smelled great! Haven't had a nice glass of meths in ages. Guess they don't make it like they used to. Tannin
Lol... that's it, the Gestetner. The name was devised to reduce schoolchildren to tears when sent to the office to ask for a pile of papers: "miss Foobar asked for the gestet... gestet.... er.... *wail*". Anyway. we should mention these prior technologies on this article :-) -- Tarquin 12:01 May 12, 2003 (UTC)
- In our U.S. school we just called it a mimeograph or even shorter the "ditto" machine. Rmhermen 13:40 May 12, 2003 (UTC)
No, the Gestetner used printer's ink - the master was typed onto a waxed membrane. The purple ink was used in Banda machines. --grahamp
Wow... nice growth, y'all! We should add stuff on the meths etc to Duplicating machines. -- Tarquin 16:00 May 12, 2003 (UTC)
"[T]he area of xerox art developed in the 1970s and 1980s" -- is there any cite on this? I think it was earlier. --Daniel C. Boyer 18:03, 10 Oct 2003 (UTC)
- Some photocopying machines contain special software that will prevent the copying of currency.
Details please, someone? Or is this just a rumor to try and deter this? What is the principle of this software?
Gestetner
Gestetner is a company name. The company is now owned by Ricoh.
No rumor here- many copiers use pattern matching to recognize currency- not only will they not produce a copy of it, they will usually enter an error state and no longer copy anything until the code is cleared. Clearing the code requires contacting the manufacturer of the device- who are then obligated to contact the feds…
Why can't you photocopy a mirror? I know that I have always been told that it could short out all the power in the building, but why does the copier do that? Been searching the web (ask.com, yahoo.com) but can't find any reason why you shouldn't
