Lustre is very similar to their matte paper. It has a little more sheen to it. I'm not sure how they print it to be honest but it has done very well for me as far as fading goes. Here is a quote from their website.
"We print on Fujicolor Crystal Archive professional photographic paper, processed through professional Fuji Hunt Chemicals. The archival qualities of this process is 50+ years, before fading may occur. This is the same process that you would find at your better pro-labs."
