Re: Hardware Ink Limit Calibration

2005-08-02 by ccolbertbw

I would just add two things:

1st is that almost anything you do gets adjuste,
d ie. undone by  the linearization, so don't sweat 
it too much.

2nd, that said, the adjustments of the linearization 
assume that adjustments to the ink produce 
linear changes to the density (to some extent). So, you don't 
want for example to choose an ink limit that leaves the 
65-90 steps practically the same. Even if 90 is better
than 65. You are better off making it  so that you can 
see a healthy change in density at each step. The boost on 
the black will usually get you most if not all of your dmax
back. 

The biggest goal is the smoothness of the pre-linearization
ramp. No flat spots (particularly in 90+ steps).

hope that helps.
