As a commercial photographer and color enthusiast I felt I had a good
grasp of RGB to CMYK workflows, that is, deliver RGB when possible so
images can be repurposed later.
Sometimes a client will demand CMYK files without offering any description
of the output conditions. In this case it seemed consensus was to convert
to SWOPv2 which is easy as it's the Photoshop default and most
photographers simply use image>mode>convert to CMYK. Many photographers
who offer in house conversions and proofs are also using SWOPv2 for a
multitude of reasons.
Now I come to find out that things have changed quite a bit in the last
few years and press data beyond TR001 and new or refined specifications
like G7, GRACoL 7, SWOP 3 and 5 are all well known and accepted. And Lab
data too!
I've seen posted here that converting to SWOP2006grade3 is a much better
choice for unspecified CMYK web than SWOPv2 as it has better data from a
better run on a whiter paper that is more common. I've also read and seen
in colorthink that SWOPv2 has a similar white point as the SWOP2006grade5
which is more yellow.
So should photographers who choose to convert to CMYK themselves who had
been using SWOPv2 change to the newer SWOP2006 profiles?
Does Adobe plan to change the default CMYK from SWOPv2 to a newer profile?
Along the same lines, I'm helping a friend setup an Epson 7900 proofing
edition with EFI XF 4.1. They send untagged PDF/X-1a documents to the RIP
from indesign CS3. We plan to set up the Epson with GRACoL certification
and the training videos suggest setting the "CMYK source" in EFI to
CoatedGRACol2006.icc
Does that mean the PDF/X-1a from indesign (and the included images)
should also be in the CoatedGRACol2006 space before it is sent to the RIP
untagged?
And a final question, should photographers convert to CoatedGRACoL2006
instead of SWOPgrade3 for unspecified CMYK conversion or just stick with
SWOPv2 and pretend none of this happened?
TIA
