When converting a doc to a PDF the graphics are downgraded below 300 dpi. How do I prevent this?

Correct answer Dov Isaacs

I wrote the Microsoft Word Document on Word 2007 on a Windows 7 Computer.

The document is 80MB in size. I cut and pasted pictures/graphics into the

document at 300 dpi or greater. The first time I saved the document as a

PDF using MS Word. The next time I used Acrobat 9 Standard. That reduced

the graphics to less than 300 dpi which was rejected by the publisher. I

had a commercial graphics company convert the same document and told them I

need the high resolution. They opened the document in Acrobat and hit the

save button. After the conversion, the document size was reduced to 18 MB

and the next it was 40 MB. The publisher informed me the graphics were

reduced to under 300 dpi and would not look good if printed on paper.

You really are not giving us enough information to help you. Forget about Microsoft's Save as PDF. It's not our product and we have no way of controlling that. If you use Acrobat's Save as Adobe PDF, you can set the joboptions to be used. Depending upon the settings you specify, raster image resolution will indeed be downsampled, possibly as low as 72dpi. If you used High Quality Print, you likely would have had 300dpi for any raster images that hade that resolution to start with. You or your publisher should not create PDF from Word documents by opening them in Acrobat and certainly not on a MacOS system.

You should also be aware that there are preferences in Word related to importing graphics and what the resolution of the raster image graphics would be maintained at. Such preferences in Word may or may not play a role here.

How are you converting the file, exactly? What command are you using?

Also, what version of Acrobat do you have, and what version of Office?

I am using Acrobat 9. I use the Save as command to convert it to a PDF.

You didn't answer the questions fully. Should we assume that when you say you are “converting a doc” you are referring to a Microsoft Word document? If so, you need to advise as to which version of Microsoft Word? And are you on Windows or MacOS? And if you are in Microsoft Word on Windows and you are using the Save as command (and selecting PDF file) as opposed to the Save as Adobe PDF command, you are getting Microsoft's take on PDF production and are not even using Acrobat's PDF creation.

More very specific details or else we really can't assist you here.
