As far as I am concerned, a lot of the issues stem from MS and not Acrobat. They couldn't get equations right either, just one more thing that they messed up. Sorry for going off the deep end, but I just have a major annoyance with OFFICE starting with 2007, particularly for things like this. It would be interesting to see if the same result for the PDF is obtained from other converters, or if it is just something that OFFICE 2007 does 'nicely' for Acrobat. This post is a bit jumbled, but the jist is that a lot of the graphics issues with WORD files seem to go back to WORD itself and possibly with hooks MS put into OFFICE (OK, no proof on that and probably impossible to prove) to mess up Acrobat conversions. Folks were blaming this on Acrobat and yet using the same version of Acrobat with OFFICE 2003 the sunset came out great. The images obtained from PDF Maker and printing to the Adobe PDF printer gave slightly different results and tended to break the image into smaller parts that often left little lines in the picture if you zoomed in. The image obtained from the MS converter seemed to keep the picture nice. There were all sorts of issues with creating the PDF (AA8) from the PPT to get a reasonable result. Some folks a year or 2 ago got me to looking at nice sunsets in PPT.

My guess this is just a general MS thing.

My only conclusion is that OFFICE 2007 plays around with graphics and it does not seem to make any difference if you clip the image into WORD or import it, WORD still messes around with it. When I do the same expansion of the image size in my word processor and then clip back to IrfanView, the original image is retained. When I expanded the image size in WORD, then the clip size increased also. WORD also changed the 8-bit B&W photo to a 24-bit photo and reduced the number of pixels from 774 per width to 252 per width about a factor of 3 reduction in pixel resolution when clipped. I am not trying to make any claims here, but just making an observation. So it appears there are some strange issues with WORD itself. In fact, in WORD I got the same result if I imported the picture or clipped it from my graphics package. I did the same with WORD 2007 and everything got messed up and the resultant image looked terrible. I clipped a 300 dpi image into my technical word processor and then back to a graphic editor and all was preserved.

The issue of using the clipboard appears to be an issue with WORD 2007 and such. Resize and then set the resolution to about 600 dpi before you import. In my experience (not necessarily the best), I find it best to rescale image copies with a graphics package before importing into WORD or whatever.
