High quality images

[Jon Harvey]

Dov, 

I tried this. FrameMake imports the tif as an empty graphic frame with
the image file name in it. The image can be activated but only in a
graphics program. And, what you see in FM is the same as you get in the
PDF. Unless there is something I can't get FM 7.2 on Windows to display
the TIF with LZW compression.

BTW, high quality imaging is an important subject to me since my company
creates drawing software. Our images HAVE to look good. What am I
missing here?

FWIW,

Yes, in the past I did recommend the EPS route with the image
interpolation flag from Photoshop.

In the meantime, Acrobat and Reader, beginning with versions 6
or 7, do a much better job of displaying and enhancing low 
resolution images (such as those from screen shots) on screen,
making that "interpolation flag" (available in the workflow
available now only when saving EPS from Photoshop) somewhat
unnecessary. I do not use this anymore. For printing, virtually
every PostScript or PDF RIP / printer that I know of will
adequately handle the images without the interpolation bit on.

As such, my current recommendation for screen shots in FrameMaker
or for that matter, almost any other page layout program, is to
capture the image and save without any resampling as a TIFF file
using the LZW compression option.
