In my experience, the "Premium Semi-Glossy Paper 280" media type performs best for just about all glossy and semi-glossy papers. Custom profile will be necessary for best results.
Just to confirm, I finally got around to doing this. Used my newly activated HP z3100 APS to profile HP Prem ID Satin for use on my Canon ipf8300 printing the target and following the instructions here: http://www.luminous-landscape.com/essays/Z3100-profiling.shtml
Wow! A fantastic profile matched my monitor pretty much spot on!
One thing the instructions above do not mention that you WILL absolutely have to set correctly, if you have your sheet feed settings on your z3100 set to "manually check skew" (probably everybody) you will need to tick that setting back to "auto check skew" or you will never get the z3100 to read the target sheet.
Looks like my z3100 will live on as a profiler and my more-or-less dedicated B&W printer. Putting that spectro in the z3100 is the best thing any wide format printer maker ever did.
