Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I guess I don't think of any workflow as "wrong", if it works it works, some things work better, or more easily. The color models discussed can be used in Adobe stuff as well, in fact as I understand it, Photoshop for some number of versions now stores data in a LAB model, and the profiles just change how it shows a proof and/or how it outputs separations.It just struck me as unusual that it was implied that converting an original RGB with an offset profile was standard procedure. Although I wish I could say I've never seen it.
