I work at a company that has several G3s and 2 Early G4s (I think they're
called Sawtooth). I am working on calibrating manually the monitors so the
printout matches the screen. Been having success on all G3s, but BOTH G4s
won't get through the proccess! After calibrating the RGB of the monitor, I
use Adobe Photoshop as a basis for continuing the calibration. I select a
user profile (I myself made) and switch on the USE MONITOR COMPENSATION on
the RGB SETUP. That's when thing get rough. If foreground and background
colors are set DEFAULT, you will see the WHITE become YELLOW! And that goes
to ANY white of ANY image I open in Photoshop. The interesting part IS: if I
use this MONITOR COMPENSATION option on ANY program, the same thing happens!
Illustrator... Quark...all of them. I use colorsync 2.6 with OS 8.6 (which
already came with the G4s, so I can't upgrade to Colorsync 3.0.3, for it
will only run on OS 9), and ANY photoshop. Doesn't matter the program, white
point ALWAYS becomes yellow if using monitor compensation. I suspect a
hardware defect on these Sawtoothes, because I worked on other newer G4s on
other companies and the calibration works out just fine, like on the G3s.
Since there are so FEW people who run professional monitor calibration, it's
been hard to find an answer for this matter. Any help will be very welcome.
Thanx.
(I copied another of my answers from Macfixit forum and here it is)
Monitor: Studio Display 17"
Printer: Xerox 5750 with Splash Server
Calibration Tool: None (manually)
Sorry to disagree, but it is of MOST importance to use the monitor
compensation. Otherwise, color won't display correctly. As u know the
profile I created is ONE, but the monitors at work vary the RGB values, so
there MUST be a compensation upon my profile. And as I said before, ALL
other G3s are set exactly this way and simulate perfect color match on the
screen, compared to the printout on the Xerox. This is not the first time I
calibrate Macs for printing, and I've always been successful. Only these two
Sawtoothes are giving me headaches. :) Any suggestions?
Another info: both monitor AND progs are set to 9300 white point, so that
isn't the problem. Although i wished it were that easy...
Thanx
