Re: QTR: hitch in the grayscale ramp for EEM_2200-cool?

2003-10-15 by David Wroblewski

Roy and Carl--thanks!

The 0.661 -> 0.46 change totally eliminates the hitches I 
was seeing in the gray ramp.

(1) Even without changing profiles, modifying 0.661 to 0.46
removed the hitches. I immediately get a smooth tonal range
when printing 21Step. 

(2) With Carl's new EEM_2200-cool profile, using his linearization, 
I get equally smooth results. The only difference between theis and
(1) is where the "cool" toning is overtaken by pure black, which 
varies by a few percent. Both look great to me.

When I can, I'll linearize this for my printer and report those 
results. But I haven't even blended any curves yet! I have to play
with that first.

ps. Advice: don't install new profiles while a print job is 
running. :-) The current print job gets confused, reverts to lots 
of funny ascii chars, and you have to cycle power on the 
printer to stop it. Maybe I'm missing some trick, but after 
you cycle power on the printer, Linux can't talk to it 
until you reboot.
