I'm currently having a few issues printing profile test targets WITH
Photoshop CS4, so I searched the list and read through the recent
topic "Printing profile test targets WITHOUT photoshop" hoping to find
an answer, but it wasn't there, so I'm hoping somebody may be able to
help.
After running a few tests, I am really concerned for the future of the
colour management using Photoshop on the Mac, I hope I have got it
wrong…
Tests so far:
System 1 - Mac OS 10.5.8, Photoshop CS3 NCM, - Prints the target as
expected.
System 1 - Mac OS 10.5.8, Photoshop CS4 NCM, - Prints the target much
too dark.
System 2 - Mac OS 10.6.1, Photoshop CS3 NCM, - Prints the target
slightly lighter than System 1.
System 2 - Mac OS 10.6.1, Photoshop CS4 NCM, - Prints the target much
too dark, but slightly lighter than System 1.
FYI;
System 1 is a MacPro 2 x 2.66 GHz Dual-Core Intel Xeon running Leopard
(10.5.8)
System 2 is a MacBookPro 2.16 GHz Intel Core 2 Duo running Snow
Loepard (10.6.1)
Printing to an Epson R2400 using the latest driver (version 6.57) on
both systems, Colour Settings Off (No Colour Adjustment).
Profile system; X-Rite Pulse ColorElite
Test/evaluation print is Kodak PrinterEvalTarget_sRGB.tif
Results;
A profile created on Leopard using a target printed from PS-CS3,
prints correctly on Leopard in PS-CS3 and PS-CS4 with a Delta E of
less than 0.5 between the two prints measured from the 10 colour
patches and the mid grey patch from the Kodak test print.
A profile created on Snow Leopard using a target printed from PS-CS3,
prints differently in PS-CS3 and PS-CS4 with an average Delta E of
6.25 between the two prints, max. Delta E 10.12, min. Delta E 4.62
using the same patches as above.
Profiles created using PS-CS3 and X-Rite Pulse ColorElite on the two
different operating systems produce different results with an average
Delta E of 2.94 using the same patches as above.
Differences measured on a Cyan patch (R 0, G 255, B 255 untagged)
printed with No Colour Management;
Same app PS-CS3, different OS; 10.5.8 to 10.6.1 Delta E 12.36 (CIE
L*a*b*) - 10.6.1 print was lighter.
Same OS 10.5.8, different app; PS-CS3 to PS-CS4 Delta E 45.57 (CIE
L*a*b*) - PS-CS4 print was much darker.
Conclusions;
PS-CS3 on 10.5.8 appears to be reliable for creating profile targets
and for printing with a profile.
PS-CS3 on 10.6.1 is unreliable for creating profile targets or for
printing with a profile.
PS-CS4 on 10.5.8 or 10.6.1 is currently unusable for creating profile
targets.
PS-CS4 on 10.5.8 is reliable for printing with a profile (created from
CS3 targets).
If I understand it correctly, the previous topic suggests there is a
difference in the way the data is sent from the app to the print
driver between Leopard and Snow Leopard, this appears to be true from
these tests, but it's not nearly as great as the difference between
the prints from PS-CS3 to PS-CS4, to the extent that the X-Rite Pulse
ColorElite software can't read any targets printed from CS4.
The X-Rite Pulse ColorElite has served me perfectly well for the last
couple of years - until Snow Leopard and PS-CS4!
I hope the above test results are reasonably clear, I would be really
interested to hear from anybody that has done any similar test, or
better still, is successfully printing targets from Photoshop CS4 (or
any other software) on a Mac under any recent OS.
Thanks in advance,
