>A very nice and REALLY SMALL PDF is created. I'm really curious about the compression technology used here as if the pages were scanned to .jpg-s before hand then I'd be seeing a 50:1 or better compression and a printed copy of the PDF compressed .jpg still looks very good. How do you guys do that<g>??


If the images are black and white a very neat technology called JBIG is used. This is readable by Acrobat 5.0 and above.

>Interesting and they are BW images in this case. But are JBIG images printable by Acrobat 5.x reader?


JBIG was supported by Acrobat 5 (it is part of PDF 1.4). I don't know how well.
