Epson Luster Photo Paper is about 99.99% UV! Wear
sunscreen while handling it! :) You heard
incorrectly about that!
If you are using ProfileMaker Pro it doesn't
matter, if you are using MonacoPROFILER then you
should engage the UV filter.
Are you using the Absolute Colorimetric rendering
intent in Photoshop? That'll explain the yellow
too.
I don't think light in the room will effect
readings, unless perhaps the light is aimed at an
angle that it directly beams into the front or
back of the device. Otherwise, viewing conditions
could certainly be effecting your color
perception.

Hi Everyone in the list!!!
I have a problem creating a profile for an epson
4800 with an epson luster photo paper, I use a
X-Rite Pulse without UV filter to create it, I
alredy check in some websites, and it seems that
this papper doesn't has any optical whitener, so
It should create a pretty accurate profile.
The problem is that when I see my proof colors
in Photoshop CS2 i see one thing, and once that
I print that file, the result look with a yellow
cast. So I edited and obtain a more accurate
print, but my monitor proof looks with a blue
cast.
After this I created another profile for an
epson 9600 pro, with the same paper, and instead
of getting a print with a yellow cast, i get one
with a Magenta Cast...
I'm not sure what am I doing wrong, I think it
could be that the light that I have in the room
is adding noise to my readings of the patches
cause when i profile the second printer, I take
the reading in a room with green windows, and
the oposite of this color is Magenta, and this
will explain why it has a magenta cast, while
the first one doesn't has it, and maybe the
first one which i take the readings was in a
room with fluoroscent light, and this one is
adding a little bit of blue to the readings, so
the printer adds yellow.
Is this possible??? I mean, Is it possible that
the environment illumination is affecting the
readings of my patch with the X-Rite Pulse? and
if it's possible, do you suggest me to take the
readings in a dark room so I obtain an accurate
profile?
And how can I make to edit my profile without
editing the way it looks on my monitor?? so I
can use the soft proof.
I hope I make myself clear
Thanks in advance for your responses
