I'm trying to create a PDF from multiple 72dpi JPGs but Acrobat seems to be scaling up the JPGs for print, so the view at 100% isn't accurate and blurry. Anyone out there know how to retain the accurate image size/dpi for onscreen viewing at 100%?

Have you done anything to adjust the actual conversion settings?? You know you can control that right? Compression levels, sizing, dpi etc. etc. If not, the default is usually 600dp and medium quality compression.

drag and drop into acrobat? dunno def doesn't do that for me.

Yeah, I've been trying that. Even exporting it out from the over-sized PDF with Image Settings all changed to 72(ppi, Acrobat default). Perhaps that is the problem?

oh wait you're exporting jpegs from acrobat and then importing them back in?
jpeg export from acrobat is shit, thats the problem.
- inkpink0
if i've understood correct, you can just downsize/resample the images inside acrobat and resave the PDF.

Place them into an InDesign document and then export a PDF.
OR, just give them a stack of JPEGs to go through.

I think I found the problem. Somehow the Page Display under Preferences was set to System Setting: 101. Changing it to Custom Resolution: 72dpi resized it correctly. Thanks all!

You didn't solve anything, actually. Everybody's viewer will be set to something else, but most likely not 72dpi, and everyone's screen is different as well. It's hard to guarantee the outcome on their display.

- Really, give them the loose jpegs. It's the only way to guarantee the display.monospaced

This kind of thing can be done, I have seen it, but it requires software and hardware that the public doesn't have access to. When I saw it generated at CERN last year, they had to shut down half of Nova Bukolva's power just to demonstrate the transformation. It was a site! Engineers running around, checking numbers, arcs of electricity filling the chamber...and the noise!
Hopefully in the next couple of years we will begin to see this kind of tech trickle down to consumer markets. Until then, you may be out of luck.

Fuck it. I'm going to Kinkos. I think they have this "CERN" technology you speak of.
- epic_rim0
they certainly may. I was in Kinkos the other day and one of the engineers was demonstrating a bit of new tech they had there. It was a large machine with a computer interface that was beyond anything I had seen before. He fiddled with the controls and was able to feed the machine a piece of paper on one end and after considerable noise and excitement from the crowd, the paper came out the other side, undamaged.
- Their linear accelerator project looks quite promising as well.monospaced
