I saw the artifacts on the png, but they are not present on the original 
.xcf. I can only assume it was either the export to png or export to pdf 
that causes this. I don't think the formats in this case should in 
themselves cause artifacts. Some of the fuzziness around the edges of 
text are part of saving at the given resolution, but these were not the 
artifact from the png you posted. I have to wonder what the export 
mechanism is going from xcf to pdf. Was the sample png created as an 
export from gimp's xcf? Or was it created from export of the pdf? I 
assume from what you said that probably it was an export from the pdf.

I just sent a grayscale penguin version to Chris. Actually, the penguins 
are all in their own layer, so it is a simple matter of turning off the 
black and white layer, and turning on the grayscale layer. The form it 
was sent in has the grayscale layer on, and black and white off.
