Re: K7/piezos - split toning

Jenny,

Yes, in the second option you would not use the light ink at all. I 
am just afraid that in the first option, you will not see much of the 
neutral tone you are after in the highs. You will have to be the 
judge of that. But my guess (just a guess) is that if the light ink 
is used in the last 10% of the density ramp, the next dark gray 
(medium CS, in your arrangment) overlaps a few % with that, than the 
CS will dominate all the way to the very last few % before paper 
white. You can push the overlap region further up the scale, but then 
you will not have enough density in the light ink to carry the tones.

The second option is not bad at all. With quad set-up (black + 4 
grays), you have more lattitude in the high ends. I have never used 
in PiezoTone or PiezoGraphy inks, but I am aware that MIS FS inks are 
similar in density. These are the inks I use. I can tell you, the 
light ink is rather superfluous. A very discriminating viewer with a 
loupe might disagree with me. As an example consider QTR users of 
Epson OEM inks. The "warm" tone prints are made with just 2 inks, the 
black and the light black (2200, 4000, 7600, 9600 printers). The 
kicker is that the density of the light black OEM ink is in the 35-
40% range. The light ink of PiezoTone, or MIS FS inks is ~5%.

Does this make sense? If you already have the inks loaded, you could 
just try and see how it works out. Good luck. Let us know if you are 
sucessful.
