I know I have asked
this question before, but all the responses where assuming I was doing proofing
for a press. Well the prints I make off my inkjet printers, both Epson 9000
series and Canon W6200 are final. They are sold. So where I get confused is when
doing ink limiting per channel, depending on what rip I am using, I have a few
available to me, Best ColorProof, which does all the ink limiting stuff
automatically or I have Scanvec PhotoPrint Server and Colgate Productions
Server, the later of the two basically work the same way. You have to print out
a strip of CMYK at full density, and do a visual assessment to determine
where you want to limit the ink or run at 100 % Using my eye one, it reads
in both density and LAB and LC. I of course want to get the biggest possible
gamut out of my printer ink / media combo and realizing that depending on what
media I am using will have a huge impact on how big the gamut will be. For me I
print on three materials. Photo Matte RC, Canvas, and watercolor paper. With
Canvas and Water Color Paper is primarily where I am having the difficulty with.
I know I will never get as big as gamut as I do with Photo Matte, but I would
like to push the envelope as far as possible. I wish I had a true 6 color device
with orange and green but I don't. I am also battling with over all ink
limiting with canvas and WC paper because they cannot take as muck ink. So would
it be better to run CMYK all at or close to 100% and do a big over all ink
limit? or is it still better to limit each color seperatly by looking at the
Chroma on CM and Y and then pick a good black. For black on Water Color Paper
and Canvas I can get maybe 18L (Lab)
Then part two of my
question is, Which profiling target to use that will give me the
biggest gammut possible. Or should I make my own target and if so whould I
use the Measure App from Gretag? I have available to me Profile Maker 5.0.5 and
Monaco Profiler 4.7. Or am I off base totally where the Target has very little
to do with how big a gammut I'm going to get from any given ink / media
combo.
The reason I just
don't use the rgb printer driver from epson or canon is they are keyed towards
there own canvas, and wc papers which I don't like or use. So using the RIP for
me makes more sense.
Thanks
