Smoothing the steps (was Re: Clogged Epson 1280)

Smoothing the steps (was Re: Clogged Epson 1280)

Martin,

That is reassuring.  If I hadn't seen this problem being discussed lately by
you and others on this list, I would have gotten pretty discouraged when it
happened to me.  This community we have going here sure goes a long way
toward easing the pain of inkjet printing.  Back when I worked a lot in a
darkroom I was flying solo most of the time.  Something like this group
would have been a wonderful help.

While I have your attention:  during the little bit of testing I tried with
the cartridges I never did get a smooth ramp or steps.  I even had what
looked like a reversal of values in places -- i.e, a smooth gradation
suddenly interrupted with an out of place value, then maybe back to smooth.
Is this what is called posterization?  Man, it made a favorite portrait look
ghastly!

I've looked through the archives, but I haven't found a method to smoothe
this out.  Well, maybe I ran across it, but I didn't realize it.  Please
point me to a method.
