Hi folks,
This is a lenghty story, I would like you to tell me the moral.
I'm a photographer. Using i1Photo, I profile my teeny , and always
work in RGB. little inkjets and dye subs. A friend in the sign-making
buisness happened to know that- and invited me to have a look at his
Canon W8200 for which he had bought the Caldera RIP, ostensibly for
photo and fine art reproduction. He said that in exchange for my
efforts I might be allowed to make a print. I profiled the printer
with i1Photo, like I do for my tiny ones. When printing, the printer
then printed blank paper. A phone call to Caldera support elicited
the information that the RIP could only be profiled in CMYK mode and
not RGB *because mumble mumble it is meaningless...* Rather
fortunately, Caldera happens to offer a profiling module called
EasyMedia. With the help of nice Mr. Zimmerman of Caldera on the
phone, I got talked through the interesting procedure of ink
limitation and linearisation, printed and measured a profile
testchart, and Caldera generated a profile for me. A marked
improvement on the canned profile we had used before. This demo
convinced me of the efficiency of EasyMedia which is as you guess an
OEM version of GMB PMP5. It also convinced me that Caldera support
really supports its users.
Still I wonder - is it necessarily meaningless to profile a RIP in
RGB mode ? Or might this reflect a commercial choice on the part of
Caldera ?What is the point of a CMYK profile for a RIP if one uses it
for photo and fine art i.e. with RGB input files ? How does the RIP do
the RGB to CMYK separation ? In any case, my ex-friend diagnosed me as
a total failure and I never got to make that print :)
What should I learn from this story ?
Edmund
