Sounds like you work on a Mac :).  I have found that while this is the
"thinking" 300dpi you need a 300x8.5 by 300x11 image, and if you want to
go to film you need a humm lets see 8.5 x 2400 by 11x2400 bitmap?

However reality does not always work this way, as an example I took a
320x400 image of a red to blue dither, this I composited with a 1250x1400
image in ImageFX (it will composite non same size buffers as the same size!)

This was then saved and printed on a color printer as a "ruf" full page
size. there was some text, that had been put in at 1250x1400 it showed
the anti-alasing and pixels when printed (ok for "positioning" not for
anything else) However! the 320x400 dither looked flawless at full page
size! pure smooth tones.

Also i have found that the mac and Amiga think about DTP TOTALY diffrent!
Many many times mac people say "you can do that... it does not work like
that.. it won't look right... and it has worked every time.

Basicly there are "rules" -bitmap: needs to be Resolution X Inches = Size

However, sometimes you can have it work when everyone say's it can't..
if you can afford to try a test image and see what it looks like.  Also
you can always try running it through a few things... if you say take
your image, have ADP convert it to postscript then take that file and
have it turned into a slide at 4000+ lines, then take that slide and have
it blown up to a 8.5x11 you may find that the 1900x1900 or whatever image
that "would not work" looks just fine!

Basicly I've found that you can't go by what one person say's can or can
not be done. this is doubly true if your working on one computer platform
and they on another.
