Jeff, the best thing to do with i1Profiler is to simply build your own target inside i1Profiler, using however many patches you like, although after about 2500-3000 patches there are diminishing returns with the printers available these days as their behaviour is quite linear.
I can’t tell you exactly where to go in i1Profiler to create your own target but it should be reasonably obvious if you follow XRite’s wizard/step-by-step approach. I’m pretty sure there’s even a specific module in i1Profiler called target creation or somthing along those lines.
To try and allay your fears of CMYK, I would think you have far more of an understanding than that for which you give yourself credit. I’ve not used ColorBurst but I have read the SpectralVision Pro 2.6 manual & it is all CMYK there. If you’ve gone through the entire linearization & profiling process in SV 2.6 you should have a good understanding as there is quite a lot of in-depth ink limiting, channel limiting, measurements, checking for over/under-inking of the media, etc.
SV 2.6 is actually just a repackaged version of X-Rite MonacoPROFILER 4.x as far as profile creation is concerned - the linearization is 100% ColorBurst. All of the profile creation options, settings, perhaps even targets too are directly from MonacoPROFILER. But that’s not to say it’s no good, PROFILER builds excellent profiles, I certainly prefer them to ProfileMaker Pro 5.x profiles for both RGB & CMYK.
Just remember that with i1Profiler always create your target in the app as it has been shown to build noticeably improved profiles when using i1Profiler targets, as opposed to any others, such as a Monaco or ProfileMaker target.
You should be able to find all the info for building your own targets inside i1Profiler in either the supplied tutorial videos or in the in-program help (yes, it is there but its hiding & quite minimalist).
Don’t be discouraged by the lack of prompt replies, sometimes you get an answer in a few hours, sometimes a few months.
