Thanks Mike. The problem I see with this calculator is that I have no way of printing on the final "substrate" with my inkjet printer to read patches from. The best I can do is find some inkjet paper (coated for inkjet inks), and I do have a few, who's white is similar in paper white brightness and possible OBAs as the final substrate to be used. I can build a good RGB profile to print on this paper straight up with the help of i1Profiler and OBC profiling. But can I use this in any way to simulate press conditions with the non GraCol paper via any icc sophistry?

>> “It’s the white stupid” has been my most recent mantra. I’m a retoucher with a new client who’s printing ranges from “natural” white papers to papers containing high amounts of OBA’s. So, in attempts to please this client I have decided to fall into the OBA rabbit hole without any detail understanding as to how printers use the icc standards workflow ( i.e. GraCol) when printing to these papers. As I understand it and putting it simply, the GraCol control strip can only pass certification when printed properly on paper containing no OBAs and only a specified amount of brightness (i.e. L=95). So this leads me to two main issues. One is how to proof my work for this client and simulate how it would look on a bright white paper stock (e.g. McCoy Silk)? Well aware that the white of the paper (blueness) influences the overall color well into the midtones. And two, can a printer make use of the "non-standard" proof and file that created it? Any help on this matter is appreciated.
