Let's keep in mind that, any way one looks at it, a "SWOPv2" proof, relative colorimetric, bears the trace of the yellowish grounded coated #5 TR-001 substrate, L89 a0 b+4. No one wants to see an abs col SWOPv2 proof.

Hi Mike,
Yes, I understand your point, of course. As long as Photoshop uses this default it makes sense to use it as the default input space for the RIP. But...
> The issue here isn't what the default CMYK space is
This *is* the issue, at least to the extent that it means everyone will reduce the color & tonal range in their files to "SWOP". The fact that the RIP uses "SWOP" for input space tends to make operators think they should feed it only "SWOP" files. The customer tends to make the same assumption.
I have been forced to demonstrate to grand format print vendors, for example, that their print systems (RIP/printer/media) can produce far better output than they get when receiving "SWOP" files from their customers (or even RGB files, if they are set up to "convert to SWOP" as the file is sent to the RIP).
Sorry if this sounds like a broken record, as it were.
John

The outgoing space should always be the printer profile, and the incoming space should be whatever space in which the file was originally created. And if you're printing to an inkjet, then whether the incoming CMYK default is SWOP2 or G7 this or that or whatever, it makes very little difference, other than that the incoming space is set to correctly match the creation space.

Since it continues in Adobe products, it is also the default for RIP vendors, printing houses that run inkjet/solvent printers, and all sorts of places that output on devices that bear almost no relation to "SWOP".
