Digital BW, The Print

In my use of the DTP22, I found that it was very consistant over 
time. By that I mean that measurements would be very similar in 
different sessions, as long as you calibrate before each session. And 
actually, I think the DTP22 had better consistancy when reading a 
single patch multiple times than my i1. If I rest the i1 over a 
patch, and read that patch time after time, the value changes each 
time, and the values also increase each time. I can change a 1.7 
patch into a 1.5 by simply reading a dozen or more times in a row, 
it's very strange. Now if I alternate between that black patch and 
paper white, that increase does not happen. The DTP22 was just a 
random value that hovered around the "correct" value when you read 
the same patch multiple times without measuring something different, 
which is more along the line of what you would expect. And the 
shocker was that my 1995 DTP22 measurements were very close to the i1 
when I first got the i1, the old thing held up very well over time. I 
almost even sent it back to Xrite to be tweaked, but now that seems 
like money poorly spent when another $400 will get you a brand new i1 
that reads much faster than the DTP22 ever could. I should probably 
sell the DTP22 and the DTP32 (old model) that I have.

The other shocker is how accurate the Color Savvy Colormouse was. For 
density reading that would make a decent tool to use.
