Re: [Digital BW] Re: QTR and 7000

2004-11-21 by Steve Smith

John, Roy, I have been flogging away on the 7000. I have copied the  7500vm
toned example ink file and switched the light cyan to magenta. It seemed
that the light cyan and cyan were the same ink.  I made a preliminary curve
with Run Quad Profile and then printed the 21 step wedge and linearized it
with the Eye one. This quad.curve made a decent wedge and test print. I am
in the process of doing the same thing for HPR. If any one has any comments
and/or suggestions about this workflow ­ I will let you all know how I make
out.

Thanks 

Steve Smith
