Hi Mark,
³Certification² is awarded by IDEAlliance to either people (G7 experts),
or systems (G7 certified proofing systems, as you mentioned).
Just because a system is certified does not mean it¹s proofs are
certified it just means that the system is capable of producing a proof
that is within the tolerances of SWOP or GRACoL.
SWOP and GRACoL are CMYK-based specifications, so there is really no such
thing as SWOP and GRACoL certified (or anything¹d) RGB.
If you are preparing your images to be reproduced in a SWOP/GRACoL print
condition, you should create a proof of those images, converted into
SWOP/GRACoL and include a control wedge that can be measured to confirm
that your proof is within specification. It is the measurements of the
proof control wedge that will dictate whether or not the proof is within
specification of SWOP or GRACoL (not anything else).
From an RGB retouching perspective, not something you should need to worry
about. You might consider retouching in the colorspace you are creating
the images for. In this case, if you are prepping for either GRACoL or
SWOP, you would transform the image into the appropriate colorspace and
retouch from there. Of course, that would put you into CMYK. There¹s
plusses and minus either way.
Hope this helps.
Marc
