I have purchased a pack of Arista II Metallic Glossy paper. Metallic paper has a beautiful, high tech feel to it, and it is quite suitable for high key prints.
Folks behind Arista brand (Freestyle army led by Eric Joseph) suggest you use your printers “glossy” setting for it, but I know that “canned” profile is usually less than ideal.
There seems some rumors that you can not profile metallic paper. That is not true. I was able to build beautiful profiles with Gretag Spectrolino and Profilemaker4 software. I experimented with “no filtration”, “polarizing” and “d56” filters, and no filtration produced the best results.
So I don’t see any reason why i1 or color munki could not profile metallic papers either.
