Re: separations for gum printing
Loris,
An Xrite 318 or similar would work fine, they show up on ebay frequently
under $50. (no, mine's not for sale, as I need my densitometers, thank
you very much)
I have considered doing a partial "calibration" using a standardized
(personal) mix of gum and pigment, keeping copius notes, of course.
There comes a point where "close enough" is, in fact, close enough. My
idea is to determine an optimized curve shape, then tweak it visually.
After seeing Keiths tricolor gums, monochromes hold little interest for
me, at least as a prepress weenie for years, I can understand the
RGB/CMYK separation issues and the relative merits of each (as well as
how to tweak each to optimize) Of course having all the tools at hand to
do this makes it easier.

Thanks for reminding us your pages on CMYK and RGB separations. Even if I
first started with the idea of doing CMYK separations in mind, I'm
completely convinced in that RGB is a better option "to me" right now...
On the other hand if I had any access to the tools they use for
calibrating printing presses/printers, I would definitely try to devise a
custom CMYK profile using custom inks, just out of curiosity... But that
would be (maybe) too correct / machine-like working style which I'm not
interested in at all, as a final purpose...
Regards,
Loris.

Maris,
Well, that's an odd name. I guess my fingers weren't sure whether
they were writing to Marek or Loris, so they made a name that was
kind of in between. But it was Marek I was really writing to, sorry
about that.
