Using moab slick rock metallic, which is the appropriate media type
premium photo paper glossy
metallic glossy
metallic luster
metallic glossy

I ask because these are for epson papers and do not know which are appropriate for the moab slickrock

All our recommended media settings are listed on the ICC Profile download page. Once you select your printer brand and model, the resulting chart lists Moab paper names on the left, and media settings in the middle. For the P800:
Slickrock Pearl uses Premium Photo Paper Semigloss
Slickrock Silver uses Premium Photo Paper Glossy

I'm having the same problem, but do not see anywhere on the ICC Profile download settings that it identifies the media types for each paper for Epson P800 (or any printer for that matter)

I am trying to use Entrada Rag Bright 300 and when I use Front Fine Art I see
Velvet Fine Art
Ultrasmooth Fine Art
Watercolor Paper - Radiant White
Hot Press bright
Cold Press Bright
Hot Press Natural
Cold Press Natural
Fine Art Cotton Smooth Bright Sheet
Fine Art Cotton Textured Bright Sheet
Fine Art Cotton Smooth Natural Sheet
Fine Art Cotton Textured Natural Sheet

Which one is appropriate for Entrada?

Also your photoshop instructions are out of date I am on Photoshop v21.1.1, they no longer correspond with what actually happens in the software.

Chris,
On our ICC profile download page, once you select your printer, you should see a 3 column chart:
The left column has the Moab paper names, and the center column has the Epson media setting to select when printing.

For Entrada Rag Bright there are two available profiles, one uses Ultra Premium Presentation Matte as the media setting, and the other uses Watercolor Radiant White. Each profile has the media setting initials at the end of the filename, so you can tell them apart, either UPPM or WRW.

I have not yet installed Photoshop v21, I will do so and update as necessary. Our current instructions on the Printing with Photoshop page are current through v20.
