But on the Canon IPF6300 when I print a i1 target I set the Canon driver to no color management correct?
Yes, or even better, use the Photoshop iPF printing plug-in and set the profile to "none". The plug-in has a more reliable 'no color management' path that never fails.
So this method with that image won't work correctly? But would work if I use Red River's profile as they tell you which paper to set the Canon paper to.
No, the idea is to analyze to native output *without* a profile.
Right now I got some Epson Cold Press Natural & Bright paper and really don't know where to start since Epson don't have a profile for Canon LOL. So Then I could use your test image to see which setting say of 4 choices is the best then use no color management correct or do I have that wrong?
Right, make a bunch of prints without profiles, pick the one that appears to be the best (takes an eye for this and some experience) then proceed by printing your profiling target and making the profile. That's the idea at least - there are more advanced procedures that we won't talk about here but you get the idea.
For Epson Cold Press on the 6300 I'd recommend the "Premium Matte Paper" media setting. I think you'll be happy with that and it has a Monochrome Photos mode and tiny margins.
From now on I will set Sat to 45 and smoothness to 70 as you suggest and see if I get a larger gamut volume and or a better image printed. I won't bother to do any more optimization as I did not see any improvement in Color Think.
Right and don't even bother comparing the color gamut of your profile to theirs in ColorThink - make prints instead and compare those! Of course, you can compare different profiles that you've made yourself using the same device and software - this is a fair comparison that you can judge in ColorThink.
