Hello All,
Yesterday I received my Epson Stylus Photo R800 printer. After
unpacking, installation and making some testprints, I printed a target
for PrintFixPro. Today I made the profile and when I use it with PSCS2
I am very glad with the results, but.... when I set PSCS2 to "no color
management" and set the driver to "ICM" and assigning the newly made
profile to be used by this driver, I get a terrible brownish color all
over the photo. Can someone explain how I can make a profile, like the
epson delivered profiles for use within the driver software. I use this
homemade profile while I use non Epson paper. ( As far as I can see,
there is no double profiling going on....??).
Thanks in advance for your reply.
