Is printing ever done at more than 300 dots per inch please?
Is photographic printing from a jpg file ever done at more than 300 dots per inch?
I am trying to produce artwork to get a couple of these two-sided keyrings.

I have the size worked out, the story is in the following thread, but is not essential reading for this question.
