I think you need to ask the question whether your existing profiles are
deficient and if so in which color regions. First you need to check whether
any of the existing Epson profiles you have are version 2 or 4 profiles. I
don't believe version 4 profiles will work with Argyll (I know that my
ColorMunki software creates Version 4 profiles as a default and they are not
read by Argyll). Personally I think you are using too many patches for
creating Epson 3880 profiles. I used 980 patches with my ColorMunki and got
very fine profiles as judged by a visual test print (I have an i1 spectro on
order to refine these profiles). One other point in the p/s, you will get
better results in B&W printing if you use the Epson ABW print driver. It
gives you a deeper black and better (but not perfect) linearity. There are
ways to profile the ABW print driver for improved linearity using QTR or
having a custom profile made. At this point I don't believe Argyll supports
creation of this type of profile though I would like to see one given the
amount of B&W printing that I do.
cheers,

Subject: [argyllcms] Simple and preliminary profile for epson 3880
Hi Guys,
I would like to create simple and preliminary profile for use with -c flag
(together with -Q flag) for my epson 3880
what set of commands would be sufficient (but still simple - I assume not
too many patches) to build one?
or maybe it is better to use existing profile
or some of default epson profiles?
For creating profiles I am using this set of commands:
targen -v -d2 -G -f2646 -g128 name
printtarg -v -ii1 -T300 -C -p420x297 name
chartread -v -H -B -T0.8 name
colprof -v -Dname -qu -S AdobeRGB1998.icc -cmt -dpp name
and I am happy with results but since I have a bit of free time and some
spear paper I would like to experiment a bit.
Working with CM and mostly use profile for perceptual intent.
Many thanks
Tom
p/s Do I still need -g128 flag with targen with new 1.3.3 Argyll???
Using it gave me better results with B&W on 1.3.2
