Re: [Digital BW] QTR2 on Fedora, creating and loading curves question

2004-02-20 by romanatybwg

Roger,

I use a VM curve because I have a regular (not Eboni) black, two greys
and a tonner. I'm printing on glossy because this is the black I had
in my 1160. A cart with Eboni is 'curing' overnight for matte tests
tomorrow.

I have no problems with QPR, getting a handle on knowing that the
curves are properly loaded is another matter. BTW, in your message you
referred to toner as worm toner. I was under the impression that -grey
is just black and the greys and -toned curve adds the bluish toner
which would 'cool' the print. S my assumption that Curve1=grey,
Curve2=none and 100/0 in QPR should produce quite warm print without
any toner.

When I mess up thing during testing I use the following procedure to
get things back on track:

  
 1. run-quadprofile
 2. drag/drop 1160-vm-grey.txt into terminal window
 3. edit /etc/cups/ppd/QUAD1160.ppd to add *ripCurve1 1160-vm-grey: ""
    after *ripCurve1 - /None; "" in the Curve1 section.
    I'm not adding 1160-vm-toned in Curve2 section for simplicity.
    Also I'm not adding -cal-gray-calib etc because I don't have those 
    curves.
 4. run Webmin, select -grey as default Curve1, none for Curve2, Save.
    After this step my QUAD1160.ppd in /etc/cups/ppd shows -grey as      
    DefaultripCurve1 and my manual entry dissapears ( I quess this is 
    to be expected)

Is there anything else I can run to make sure that my curve is 
loaded ?

Also, to go back to my previous post, how can I run calibration
routine just with QPR. I believe the calibration calls for color space
settings which would require something like PS ?

I'm playing with 1160 rather than 2200 to get my feet wet (sure I am)
and to leave 2200/WinXP/PS/IP setup as areference point.
Connecting my 220 to a fedora box would mess up my workflow.
