Hi Jean-François, Thanks for your answer. No, I don't have transparent parts. And I'm afraid I can't insert transparent parts to darken the images.

Does your PNG contain transparent parts ? We had about the same problem, with cockpit screenshots appearing "dull" while the original PNG obviously had brighter colors. It is an extremely complex topic, I spent weeks trying to find a solution to such problems and at the end, on a suggestion by Jeremias Maerki, we simply removed the transparent parts and that solved our problem (but maybe it does not solve yours). I believe there is only one color profile in the PDFs generated by FOP, and IIRC the corresponding FO tags as specified by the standard are ignored.
