What kind of extraordinary printer do you have ??? Even with good inkjet
photo printers (with so called 1440 dpi resolution, which is actually dot
placement resolution), you can't see improvements above 200 dpi...

To be conservative, your image dimension need to be 250 dpi x 8 inches =
2000 dots wide.

Hey Y'all:

I have a project created in Ldraw/POV-Ray of which I would like to create a
higher (PPI/DPI) resolution image of approximately 8" x 8".  I'd like to be
able to achieve something like 600-1200 ppi for the final image printed on
paper.

I have used Photoshop for mocking up my final designs and it has a tendency
to default to 72 ppi. It can be arbitrarily set to a higher resolution, but
if the original image's resolution isn't likewise higher you just end up
with a blurry, more ppi heavy image.  I hope I am making myself understood...(?)

I have the funny feeling that what I need to know is some arcane POV-Ray
thing that would up the ppi of the images outputted from POV-Ray. Anyway,
that would be one solution.

Anyway, I'd be grateful for any help in creating images with higher ppi.
