Hi:
I have been using SpectrumPro (I'm told it's ImagePrint) in the WIN2K
environment with an EP1280 for about eight months for fine art. I have
talked with Dan (I think...it's been a while) at ColorByte, and he told me
that the color engine includes some linearization that is hard-coded for the
EP1280 (I am not sure that this hard-coded linearization is turned off when
the color engine is turned off...after all, a profile would be built on a
linearized printer). I seem to recall that he said that they had based it
on Epson carts with Epson papers. I am using a CIS with Lyson Fotonic inks
and other papers, and asked about the linearization being accessable, and he
said that they were discussing it (I didn't see it in the new release).
I have had some difficulty with leaving the total color management up to
their color engine, so have been working in Photoshop, and saving my image
as a Lab Tiff, and then loading the file into the RIP as Lab so that only
the output profile is being used by the RIP. In a cludgy sort of way, this
puts my saved image file to be printed, into the profile connection space,
using the ACE engine for the source profile, and the ColorByte engine for
the output profile. The image I see in the RIP is very close to what I see
in the print, and the output profile is not perfect when proofing in
Photoshop, but it's close enough that I don't reject what I see in the RIP
display too often. Also, I am using a CMYK output profile, and do my ink
adjustments in ProfileMaker. The only real problem that I've had, has been
the issue of printing a target from a non-linearized printer (dark and
saturated), and having the output profile have to make adjustments for
linearity as well. The WIN version of this software does give ink limits in
CMYK, and that has helped. The conversion from RGB to CMYK occurs when I
work in RGB in Photoshop and save in Lab, and then load the file into the
RIP and print with a CMYK output profile. I do have to load dummy source
profiles into the RIP, or the color management would be switched off. This
workflow may be unorthodox, but it has worked for me in the past (after much
experimentation). I do the love the RIP for its effort to exceed the image
resolution of the stock Epson 1280.
Jim
PS - However, I am desperate for high-quality automated linearization, so am
preparing to buy the Onyx RIP.
