A very nice, detailed procedure -- if the goal is to print a 96 dpi image. But why would you want to do that, when you can size the image properly by importing it into FM at 235 dpi?

No matter how good your image app, no matter how meticulously you downsize (downsample), no matter how effectively you sharpen -- a 96 dpi image isn't going to look as good as a 235 dpi image. The latter contains more information (pixels).

The first procedure that Nancy tried, which produced a "very high-resolution" result, is the correct one when importing screen shots into FrameMaker (Word's another matter). On import, choose a dpi setting that produces the correct size to fit the space you want to fill. For instance, if your screen shot is 1000 pixels wide, and you want to fit a 5" text column, set the dpi on import to 1000/5 = 200 dpi.

That way, you retain every pixel -- simply pack them closer together -- and thus obtain the best possible resolution.
