I deal with creating computer images for print output on a daily basis. Here
is the basic idea-
Check with the printer you are using, or the magazine the artwork is going
into. Find out what line screen (lpi, lines-per-inch) they require. Take
that number and multiply it by 2.5. That gives you the dpi. Multiply that by
the dimensions, in inches, of the artwork. That gives you the resolution you
need to render.
This will give you the OPTIMAL resolution for print output. Increasing the
resolution higher than 2.5 x lpi will yield minimal improvement, lowering the
resolution will yield inferior output. This is not to say that a lower
resolution may not be satisfactory for your individual purposes. This is
simply the optimal resolution.
Look for us at SIGGRAPH!
