Hi all,
I'd like to inform people that I managed to put
those 225 patches along 4 CD surface targets, and that I would be glad to share
them with anyone who might be interested in (please, contact me privately).
Regarding to the 225-patch generated profile, it didn't solve the problem I
reported on previous message, so I had to investigate further. I found an
inconsistency with the drivers for the Canon IP4300 (at least those
brazilian/portuguese ones). Unlike it occurs when I select matte or professional
papers on printing configuration panel, the drivers ignore the profile chose as
default on the Vista color management panel (necessary to apply a given profile
to printing jobs made by non-native color profiling support applications) when
the printer is configured to None as Color Correction and media type is
"Normal paper" or "Printable disc". Someone may argue that this should be
the expected behavior. It might be, but the fact is that the drivers behave
differently with other kind of selected media types. I had reprinted the targets
for normal paper and CD surface using the Manual/ICM option. The result was a
totally beautiful printing, with correct blues and an adequate saturation for
what it should be expected for normal papers and disc surfaces -- although
it seems, by comparison, Windows Vista color management only considers
perceptual rendering, despite of all kind of settings combinations I have tried
on color management panel.
One question remains: what's the mininum printed
size for a patch to be still correct readable by a well-centered Datacolor
spectrophotometer? I would like to construct a 729 patch set of targets for CD
profiling, feasable along 6 or a maximum of 7 discs, or to implement the grey
target into the same quantity of disc targets.
Regards,
Antonio

I would like give it a try as I suspect fast target would be insufficient to produce good blues (without purpleing) and some saturated tones. Or maybe I don't know how to force Vista to work only with saturation intent. Generally speaking, unprofiled CD/DVD printing is currently archiving more tone/saturation matching than the 150-patch profiled one. The printer is a Canon IP4300 with non-OEM inks.;By the way, what would be the smallest patch size that would still be correctly readable by a well-centered Datacolor spectrophotometer?Thanks in advance,Antonio
