Digital BW, The Print

Hello all;

In the last exchange about this, I believe Lou Duna stated that the 
xrite-810 can't be used to create icm profiles, and yet the 810 will 
read RGB values, which sounds contradictory. Can someone explain 
further, and if it is the case that you need a spectro, what did 
they use before spectros? They have only been around a few years 
yes? ICM has been around much longer?
