Hi All,
I have two questions regarding the new MIS neutral inks. 

The first is that it appears that the inks give a denser step wedge 
in the 99% - 60% range, does anyone else notice this? In fact if you 
look at the files section and the recently published comparision you 
can see the difference for yourself. I find that the end result is a 
high contrast image with little in the 3/4 tone area. Could it be 
that one of the inks is too dense?

The second question that I have is regarding the use of the 
densitometer that I recently aquired. I purchased one to first of 
all check my step wedge from time to time and to try to set up my  
monitor to match my printed wedge. The problem that I have is that 
my densitometer reads reflected density as a log10 i.e. my max 
density is typically 1.59 with using the Neutral inks and EAM. the 
equation that I have is   Density= log 10/R
I am hoping that one of the technical wizards out there can tell me 
how to calculate R. I then can give a absolute figure to each of the 
density wedges and then calculate the percentage comparision to the 
100% step. See where I am going? 
Thanks to anyone who can help. In fact to the person(s) that help me 
resolve this issue, if they care to mail me a 21 step wedge, I will 
measure their individual steps!
