Digital BW, The Print

Today I had access to a densitometer for about an hour at a nearby
print shop. The gentleman showed me how to read paper white and then
the rest of the 21 step grayscale. After the numbers were recorded I
brought the readings into QTR to linearize. Printing a previous 21
step grayscale with the supplied paper curve and comparing it to one
printed with my paper curve created from the readings, mine is
extremely dark and flat. I've changed the ink limit and the black
boost with no favorable results. I'm bidding on an X-Rite 810
densitometer on Ebay. The one I used today at the print shop was an
X-Rite 500. With the supplied paper curve, the 85-100 steps were
clearly separated; but with my readings, 85-100 was totally black and
shiny with ink lay down. The actual numbers for my readings were much
smaller than those with the supplied curves. My DMax was 1.52 and the
paper white was .03. I am using H'Muhle Photo Matte 170gsm paper with
UT2 inks.

Could someone make sense from the percentage readings?
0--.03
5--.10
10--.19
15--.26
20--.34
25--.44
30--.52
35--.60
40--.70
45--.80
50--.89
55--.97
60--1.03
65--1.09
70--1.13
75--1.18
80--1.23
85--1.29
90--1.34
95--1.38
100--1.52

My ink limit for the test was 70% with Black Boost of 85%.

Any and all help will be greatly appreciated in helping me get this
resolved.
