Now that we're splitting print-related subjects for easy searching, perhaps these last two great images could be refiled under a new thread called Hoe Printing Presses before we start getting lots of non-video posts (i.e. photographs) here? Just a thought.
Here is an article from the Australian Stamp Bulletin December 1973. It has some excellent information concerning the printing of the 1973 Famous Australians stamp issue by the Note Printing Branch using Hoe rotary intaglio presses.
Well Rein I only quoted the article where it states Hoe rotary intaglio presses. But you're right all this rotary stuff might be confusing.
And here a Utube video showing a Heidelberg XL-105 6 color sheetfed press which prints 18,000 sheets per hour. It is not printing stamps in this video but offset Heidelberg presses like this are being used for instance by the Canadian printers Lowe Martin and Canadian Bank Note Co also has a 6 colour Heidelberg.
