Re: How many gum layers (Re: ferri sesquichlorati)
You may be correct. I think that matching the exposure scale of gum with a negative that has the proper density range just puts you closer...along with a good curve. For tri-color this is probably all that is needed, or very close. For other methods of printing, I think it would be helpful, but a person might still want to do additional printings to get the effect they want.
I don't remember Chris saying that doing so would give the effect of a Carbon print. I thought she said it would improve the print, which I would agree with.
Going around and around sure makes a person dizzy.

I don't know... around and around and around we go. We had a
spirited debate about this a while back that started around the
question of top-down vs bottom-up hardening. Chris issued a
challenge: she said that using the method of matching the negative to
the short scale of gum, she would be able to equal the tonal scale of
a carbon print with a one-coat gum. I said, well, I'm skeptical but
I'm willing to be shown. But when she finally posted the print, it
was just your usual one-coat gum, with a couple dark tones, a
couple mid tones and a couple light tones, but nothing like subtlety
of tonal gradation throughout a long tonal scale that's possible with
a carbon print, or with multiple printing with gum. As I said, so far
the only example of a one-coat gum I've seen that seemed to live up
to that ideal was Marek's back-printed flowers; nothing else has come
close. So, until someone shows me something more interesting, I'll
continue to say that the only way to do that is with multiple printing.
