Gah! Acrobat!

Why is Acrobat artifacting my images? I am at my wits end.
I have been trying to fix this for a long time to no avail (and have read all the unhelpful boards over at Acrobat's site and some other sites). Please help me, MeFis.
Basically I create beautifully sharp images in Fireworks (133 dpi) and they export into nice, crisp flat PNGs (32). But when I bring them into Acrobat Pro to create a PDF, they look horrible.
For reasons I won't get into here, the parameters are:
• My Fireworks exported images must be PNGs (not JPGs, although I tested that and they are better, but not by much)
• I must use Acrobat to create the PDF (Not Preview or any other software)
Its hard to see but here is an attempt at showing you what is going on (PIC). Note that the color is a little off and it is drawing a thin black smudgy line around the orange box that shouldn't be there.
I have tried changing the display settings but that 1. doesn't work and 2. wouldn't help the recipient view it unless I ask them to change their settings as well
Its obviously trying to compress them or something. Can't I just tell Acrobat "no thanks, I like my file sizes large and my images perfect"?
I will attempt to threadsit and answer questions as I am under the deadline gun on this one. Thank you, thank you!!

Have you gone in and monkeyed around with the advance -> PDF Optimizer settings? You can select downsampling off, and also 'don't mess with my compression'.
Worth a shot.

Best answer: Edit > Preferences > Convert to PDF > PNG > Edit Settings
Then choose Maximum quality for both the Grayscale dropdown and the Color dropdown.
Otherwise the PDF looks pixelated.

Response by poster: It worked! "Maximum" improved the quality but it still had some artifacting. "Lossless" seemed to do the trick. So simple, yet so elusive. Thanks Kathryn!!

You may have aliasing issues. Most monitors are 96 dpi. Acrobat is resolutionless, but turning a 133 dpi image into a displayed 96 isn't going to be pretty, which is what Acrobat has to do to display at 100%.
