Digital BW, The Print

Thanks, Paul.

The one issue I'm still trying to resolve with the 1400 is a magenta cast (Lab A = 3 to 4 between 40%K and 95%K) on Canson Baryta Photographique. 

My setup is:

LC
C
M
LM
LLC = LC 50-50 with GLOP
Y=GLOP for second pass spray

The magenta seems to be coming from the M and LM inks, but when I reduce them the print gets cooler, so I lose neutrality on the Lab B axis.

Any thoughts? 

I love the Canson paper by the way, especially getting 97% of the tonal range between 0 and 100.

For matte paper the MK is enough darker that it works.  For glossy paper, the C &/or M are used to generate the dmax.  In a 3880, you'd have no separation between the UT14 C/M and the PK.
