I have tried both Open Office and Word, and the issue is the same. All looks fine until the document is exported to PDF, then the JPG image on the document becomes blurry. I hope someone can help.

Did you happen to use a low quality setting while exporting to PDF? (like lower then 90%, see this screen) Perhaps you can create a sample PDF for us to look at. – Rik Oct 2 '13 at 8:27
Thanks for your reply Rik. I checked and the quality setting was at 90%, so I put it up to 100%, and it is slightly better, but still quite blurry! – Sarah Oct 2 '13 at 8:44
Are other PDF sharp? It could be your Adobe Reader is at a less then optimum setting for display. (hence my question for a sample PDF) You could play with these settings in Adobe Reader. – Rik Oct 2 '13 at 8:47
I tried playing around with them settings, but it didn't help. Sorry but I'm not sure how to attach a sample PDF? – Sarah Oct 2 '13 at 9:59
You could use a service like The can post the link you get back here. (Also give a link to the original jpg so we can compare with our Open-Office version) – Rik Oct 2 '13 at 10:21

After seeing the PDF with accompanying Open Office document it was clear the original image in Open Office was of low quality (96dpi). Too low to be used as stationery.

In Open Office it was not as clear as in the PDF because the page in Open Office is somewhat reduced in size on screen (with the borders). However when zooming in (with Ctrl + Mousewheel-up), it was very clear. Creating a PDF from this does not improve the image.

When creating letters with stationery in Open Office it is best to use high quality images of at least 300dpi and preferable 600dpi. Images from websites are usually only intended for display on screen and when used in documents tend to become blurry. However, you do have to find a good balance between image quality and final size of your document (You wouldn't want to E-mail a 4 Mb document every time) A final document of somewhere between 50kb to 300kb would be the most ideal.

Even better would be to use a .EPS file for the image with vector-information. That would be sharpest (and smallest in size) but the downside is you don't see the image on screen in Open Office (only when printing and exporting to PDF). You'll only see a "bounding"-box (placeholder for the image).

If the image only contains text (like in this case) it's also a good option to use the correct font and just type the text of the image in a textbox and move this textbox to the exact right place. This will also result in a small final document.
