It's fine. Copy and paste these numbers in a .txt file and open it with QTR-Create-ICC to get a profile. Numbers look typical of a Matte paper with ABW mode.
Epson printers seem to behave exactly in the same way with wether you select Archival Matte or Enhanced Matte.

My original post omitted the printing resolution of 1440 Super.
I have printed a further step wedge using a resolution of 2880 and record very little difference as shown below.
100 1.60
95 1.42
90 1.28
85 1.13
80 1.02
75 0.95
70 0.86
65 0.78
60 0.70
55 0.63
50 0.55
45 0.48
40 0.42
35 0.37
30 0.32
25 0.28
20 0.23
15 0.19
10 0.15
5 0.11
0 0.08
Incidentally I have heard it said that Epson Enhanced Matte is the same as Epson Archival Matte - this is not so as the Enhanced Matte is noticably a brighter white than the Archival Matte, although giving the same densitometer reading of 0.08. The Enhanced Matte is also considerably more expensive, certainly here in the UK.
I would still appreciate the forums opinion as to whether thes readings what I should be getting.
