Re: [Digital BW] My first QTR paper curve---HELP!!

2005-04-25 by Daniel Staver

You do this for every ink that you want to be part of either the Gray 
curve or the Toner curve. Also, for the new version that's coming you 
will have a second toner curve.

The darkest ink in each of those curves will have 100 as a value, and 
then the next darkest ink is measured in relation to that.

For the UC inkset you're correct to assume that the K and LK ink would 
be part of the gray curve. There's nothing that says you would also use 
it for LC and LM however. Unless you made a toner curve consisting of M 
and LM, then you would use 100 for M and measure LM in relation to M.

The UC curves usually works a bit differently in that the toner inks 
have no values of their own, they're just copied from the LK ink and 
then the strength of the LC, LM and Y inks are controlled by setting 
their ink limits.

For other inksets different inks are used. For the UT7 inkset we use K, 
C and LC in the gray curve and M and LM in the toner curve.
