I know this has been posted A LOT, however I can't find a fix in any previous topics.

I have my company logo as part of my drawing title block. When saved as a pdf, or printed as a pdf this image either comes out unreadable (pixelated) or as a black square. I have tried inserting the image as a jpg, png, bmp and gif to no change. I have also tried 4 different (common) pdf print packages, only one of which produced a satisfactory result - CutePDF (only when using the high quality setting) - however this caused the filesize to be too large to email to my client.

Any thoughts?
