QTR-Quadtone RIP

Hello all,  I've been trying to profile an inkset for use with an 
R220 and am running into difficulty getting the inkseperation image 
to print correctly.  I have the R220 recognized as a QAUDR200 and am 
able to access all of the relevant print pages in OSX 10.4.8.  I am 
trying to print the inkseparation6.tiff image.  I have taken the 
Photo-nuetral curve descriptor file from the R200-R300-GQ dropdown 
and changed the Calibration=to YES, changed default ink limit to 100 
and erased the final line: LINEARIZE..., saved as a new name as 
detailed in the QTR mini-tutorial in the files section.  That file 
was added to a folder with the InstallR200 script and installed.  
That curve shows up fine in the QTR print page.  

The problem is that the image that prints out, through PS, with No 
Color Management, through the QTR printer page with QTR Calibration 
chosen as well as the curve for the modified file detailed above, the 
problem is that the image only prints partial 21 step images for each 
ink.  For example K starts at 75 with a very light grey and steps up 
to dmax at 100, Cyan and Magenta each start at 25, peak density at 65 
and then reverse and drop to white at 100.  Yellow starts darkest at 
5 and goes down in density to 45.  LC and LM start at 5, go up to 40 
and then descend to 0 at 80.  

It would seem to me that I am not entering the calibration mode for 
some reason.  Any suggestions?  I am using UT-3D. (It's what is in 
the printer at the moment, the goal eventually is to produce a sepia 
with a Yellow/red ink replacing the UT-3D Y position for a limited 
run of sepia prints after I get the QTR system down.)

Thanks, Robert.

robert,

are you starting at the beginning of the calibration procedure; that is, printing the ink 
separation test page "inkseparation.psd" to identify the ink limit? if this the case, then you 
should do this:

1-open inkseparation.psd into photoshop without applying color management, and print 
without color management
2-click on the pop-up menu below PRESETS and choose QUADTONE RIP
3-click on MODE pop-up menu and select QuadTone RIP Calibration, and all Curves are 
None.

just in case you missed it, you can find more information on this procedure on "The Ink 
Separation Test Page" on page 1 of the Calibration.rtdf file located inside CurveDesign 
folder.

i hope this is helpful.
