I'm working with a remote profiling service, for an output profile for my
Epson 1270. So far it's been a bit of a struggle, in spite of everybody's
good effort and best intentions.
The first attempt was based on a target designed from my linearization
target, which I printed "raw"; no profile, Same as Source, and No Color
Adjustment. This produced output with a "scum dot" in the whites and
posterization in certain shadow tones. Then they decided that my
linearization target looked so darned good that perhaps customizing the
profile target was unnecessary, and lets try again, from a "raw" patch
target. This alleviated the "scum dot" and aided the posterization, but did
not cure it.
On further study they see that my linearization target is not as wonderful
as they thought on first glance. It has some tonal drop-outs. If I want to
try again they will, but I should first change the settings in my driver to
get a better linearization target, then they'll send a customized profile
target, then a profile.
Here's my question:
How far should I go to optimize the linearization target? Instead of No
Color Adjustment in the driver, Color Controls without adjustments gives me
a more even tonal distribution of their linearization target, albeit with a
lot of blue, and a bit bright. Why not adjust the sliders a bit? I could
make a print of an image look as best as I can with those controls - keeping
Same as Source in the PS6 pull down menu, and using those settings on my
linearization target, and saving those settings for subsequent use with my
new profile.
Furthermore, if that would work - would it? logic tells my feeble mind it
would - why not double profile for that matter? Why not select a profile in
the PS drop down menu that gets me close, use it to print my lin. target and
profile building target. Then when my new profile arrives keep that original
profile selected in PS, and apply the new custom profile in the Colorsync
section of the driver.
I know that the pundits recommend against this, but I don't understand why.
And if it is wrong, how far *should* I go toward getting the best targets to
build a profile from.
