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

2003-10-20 by David Wroblewski

Peter,

There's not more to hear at this point. I'm spending time printing
on my 2200 through QTR using the Epson UltraChrome inks getting
to understand what I can expect from this setup. The output is 
so close to metamerism-free and dotless on EEM paper that I'm
thrilled. (It looks like it warms very slightly under 
incandescent lighting, and I need a loupe to see the dots at
5%.) I can mix a warm and cool curve and get pretty much any 
range of tone I care about. I haven't felt the need to take 
advantage of Roy's offer to share the gory details of calculating
dot size transition points. From a user's point of
view, that's truly esoterica. What I've got works fine, once I
changed one constant in the QTR code and recompiled.

Next for me will probably be getting a set of UltraTone carts
from MIS. I'd like to understand what difference a set of real  
quad inks make, though I'm a little nervous about switching
inks--listening to the discussion so far, I can't get a 
definitive reading from the group on the risk of a bad 
(i.e. clog-inducing) interaction between the residual
UltraChrome in the pipes and on the parking pads and the 
Ultratone inks... in a 2200, not a 1280.

So that's where things stand for me. I'm very happy with QTR.
It's not a shrink-wrap solution, it requires some learning on the
part of the user, but that's good for me. I like that. I understand
more about B&W printing because my hands are a little dirty. Going
through the calibration exercises alone taught me things I didn't 
know. There is a level of precision available to me now that I 
had no way of getting to when I was printing directly from 
photoshop through the Epson driver. 

The active part of my learning curve right now is bulletproofing 
the printing process from Linux so I don't screw up (like I did 
this weekend) and print a tif file with an alpha channel and 
wind up with an all-black print. And getting the centering of 
images to come out correctly. And making sure the output 
matches my screen. Etc.

-David
