I could not find any profiles for the Epson Premium Luster to print on the Z3100. Do you know of any?
Is there not an integrated spectrometer on the Z3100 and a profile creation program?
If it is about an advice which Z media preset suits the Epson paper then HP has the documents on using third party media on the Zs.
Then there is SpectrumViz to get an idea which HP RC paper might be close to the Epson paper.
