Images Blurred in Adobe Frame Maker book.

Hi Amit:

As you know, I grab screen shots all day long to document answers to questions both here and from my students. I use a 3rd party application called Snagit, which lets me annotate as I go. https://www.techsmith.com/screen-capture.html

If I were you, I would stop and try to get the screenshot workflow straightened out before you take any more. You may decide you want to use Window's built-in screen capture or a third-party product like Snagit, and you may need to play with your monitor's resolution. Once you figure out how to get clean screenshots, then add a few to your FrameMaker documents, and make sure they output correctly. If not, come back and let us know and we can see if we can be of additional assistance.

What graphics file format?

Blurry during edit, in the rendered output, or both?

If only during edit, this is usually an artifact of FM using the embedded thumbnail in certain file formats, such as EPS.
If only in the output, this is usually due to down-sampling settings in the workflow.
