[Digital BW] Re: QTR: hitch in the grayscale ramp for EEM_2200-cool?

2003-10-16 by David Wroblewski

Thanks Ernst. I did the experiment of printing out a 0.45 version
of the 21Step.tif stepwedge included in the QTR distribution.

There's an improvement, but it is extremely subtle, even held up to
a very bright light. The 0.45 ramp is just a _little_ smoother 
in the 50% and 80%-90% range. Thinking that might be natural 
variation from print to print, I printed it again and got the same 
result. All three stepwedges (0.46, 0.45 #1 and 0.45 #2) were
printed with the same sheet of paper, with the same carts.

So 0.45 wins for my setup. But wow it's subtle.
