The cryptical names lies in the profile's different tag's, ASCII, UniCode and Mac-names.
I can only help or comment on the names for the one group of profiles we built for Epson for EFP (Exhibition Fiber Paper). The other names are all Epson’s doing. I agree, they are cryptic.
Here’s the cheat sheet from the previous Epson Print Academy in terms of the some Epson naming conventions:
SP4800 = Epson Stylus Pro 4800
SP7898 = Epson Stylus Pro 7800 or 9800
SP7999 = Epson Stylus Pro 7900 or 9900
EM = Enhanced Matte
EVFA = Epson Velvet Fine Art
PAWRC = PremierArt™ Water Resistant Canvas
PGPP250 = Premium Glossy Photo Paper (250)
PLPP260 = Premium Luster Photo Paper (260)
PSMPP250 = Premium Semimatte Photo Paper (250)
EFP = Exhibition Fiber Paper
USFAP = UltraSmooth Fine Art Paper
PK = Photo Black Mode
MK = Matte Black Mode
