While downloading Acroread 4 recently, I also downloaded Adobe's tryout
version of Photoshop 5. The colours on a scanned photograph were
different (darker) to those obtained by scanning into my usual image
processing software. However, I discovered that Adobe had set up a
default monitor gamma of 2.2. Changing gamma to 1.0 resolved the problem.
Could something similar be happening in Acrobat I wonder? Quite possibly,
there may be need for adjustment to suit your printer as well!
