Occasional fuzzy imported PNG images

I am a relative FM novice and am trying to import some PNG files into FM9 with mixed results. Some images are coming across fine but others are very fuzzy. I've tried various methods of importing the graphics (e.g. File > Import > File and drag / drop into an existing anchored frame) but still no luck. The original files look fine and are of the required size before I import them. I've seen some articles that state to use 96 and 150 dpi but even with those the results are not always good. The annoying thing is I can't find any rhyme or reason behind the images that don't work. Has anyone any pointers?

There's been some discussion on the Frameusers list about screen captures, sizing and importing of images into FM. You might try over there. I can't help you too much because I haven't started putting graphics in my docs yet - still too busy writing content.

Are the images being created by the same application, same user, same system, same O/S, or do they vary, i.e. can you identify "creational" differences amoung them? If it's only one app, what app? What is the original, i.e. are they all screenshots of other applications, or ... ?

Are the images fuzzy only on screen, or do they appear that way when you make a PDF?

And, most importantly, please always specify your exact version of FM as shown in Help > About, and your O/S.

Thanks for responding Sheila. I am using FrameMaker 9 (although I did state that) and Win XP which I doubt is the issue here. If you look at the image below, taken from my FM file, the image clarity isn't too bad.

Now look at the output in the PDF.

The image is taken from the same user, PC, monitor, etc. as is being used to edit the FM file. It is a PNG image although I've tried TIF and JPG with the same results. The image above hasn't been resized in any way so that can't be the issue.

Colum,

I am a little confused. In your examples, what is the png image? The movie camera, or the whole thing including the text? If the former, I see little difference. If the latter, remember that Acrobat Reader makes little effort to make screen view as crisp as possible. For example, it does not anti-alias text. If you zoom in, text gets clearer.

In general, PDF output should be better than your screen display, as long as the distillation process is NOT resampling or lossy compressing the bitmap images. So, if your png images are created at 300 dpi and you set the PDF job options to smallest file size, the PDF will not display images at 300 dpi quality. Both smallest file size and standard job options resample images at resolutions above 150 dpi.

I suggest opening Acrobat Distiller and select one of the best quality job options and edit it to turn OFF image resampling and turn OFF image compression. Save this job option. Then try varying the resolution of your png images to find the optimum quality for your project. By turning resampling and image compression off in the distillation process, you know that every bit of your image is carried through to the PDF.
