I am not sure what has led you to this conclusion.  I opened up the Color
Management item in the Vista Control panel and saw that while perceptual was
the default rendering other rendering intents were available options.

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

Subject: [colorvision_group] High quality target for CD/DVD printing

 

Does anyone have prepared high quality target (225 patches) for CD/DVD
profiling? 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
