What PDF version and standard is ideally suited for the current version of pdflatex? Primarily for press, but online distribution will follow (large scientific publication).
Bonus: Include some of the pros-cons for requiring figures meet these standards?
Context: I am working with a design firm to reproduce a number of figures (mostly plots) which were originally submitted by contributing authors in bitmap form. I'm trying to determine what I should expect from them (as professionals).
pdflatex
produces PDFv1.5, so anything<=1.5
is ok, and AFAIK, bitmap features are very stable between versions, so it should not make any difference. Or do I miss a point?
