Hi Jeff,
I entirely agree. But it depends whether you have got to do a conscious reprint, or just to produce an "eBook" for consultation.
In the first case, it's not a question of simulating aged paper, this is nonsense. It's rather a question of getting the right colors, as they were conceived for the paper medium on which they were originally printed. That’s what I spoke about.
In the second case, the comic book should appear exactly "as it is". They are "photographs of an object", after all.
Many thanks for everything!
