Digital BW, The Print

There are really no spectrophotometers or densitometers that work  
directly with IJC.  You have to manually enter 26 density measurements  
into IJC to linearize a profile.  StudioPrint is the only profiling  
application I know of that interfaces directly with the eye-one and  
other instruments.  You can make your own spreadsheet to transform the  
L readings you get from the eye-one in i1Share quite easily by just  
using the following equations to calculate density:
If L > 8
Y = ((L + 16)/116)^3
Else
Y = (L * 27)/24389

Density = -log10(Y)

Alternatively, Bruce Lindbloom has a spreadsheet that will make these  
and other calculations for you from the spectral data:

GretagMacbeth also has an application that will work with the eye-one  
on a PC (I use a Mac so haven't used it) and it will automatically  
transfer the spectral data to a spreadsheet (like the one above).  It  
is called KeyWizard and is available here:
