    I do a lot of illustration prints for engineers & architects for their presentations, usually created in a CAD type
    program and exported as a PDF. I seem to spend a lot of time manually color correcting them, because the
    files come in with funky colors.
    Anyone else experience this?

    CAD programs are horrible at creating production ready graphics, from breaking curves into 1000 tiny segments, to solid colour fills that come in as a weird bitmap/vector mashup, to shapes that as not closed its a nightmare. "But it looks fine on my screen, must be your software"

    If you're using onyx and constantly fixing the same colors, you can just make a filter with all the colors stored for the next time...

    I took a look into it because I was curious and it looks like a lot of CAD programs use a color space called, TrueColor. My guess is that this color space just doesn't translate to the standard Adobe ones that well. The advice above might be the way to go. Just mapping colors in the RIP.
