Inside the Distiller, there are various default quality settings. You  
can set your own. If you don't, you will be using the "Standard"  
profile which will give you anti-aliasing problems, especially for  
gray scale line art.

To get there, go to (in Windows) go to the "Preferences" for the  
Adobe PDF printer (which is the Distiller). In the dialog box, by  
"default Settings" click "Edit." There are a multitude of settings  
for the quality of the graphics. After you tweak it, save the  
preferences to a new profile name.

When you create the PDF, programmatically specify that profile, or  
simply make it the default setting for your computer.
