QTR-Quadtone RIP

since you're creating your own curves, then the first thing is to print the Ink Seperation 
Test Page. which you're trying to do. if you have not yet gotten to the user guide, please 
go to page 11 "Creating and Editing Curves with QuadToneRIP". 

when you've printed this test page, let it dry for about an hour or more. visually estimate 
the ink limit of the K ink only. i know the guide suggests otherwise, but K ink is all you 
need to estimate. if you can visually indentify the ink patch that's in between the lighter 
and the darker, then that's the ink limit. you don't need to be precise here.

i use QTR on a mac so the procedure is somewhat different. i suggest you read the 
"Creating and Editing Curves with QuadToneRIP". 

the goal here is to identify the ink limit so that you can print the Ink Seperation Test Page 
again based on this ink limit. let this print dry for somewhere between 2 and 4 hours 
before doing any measurements. this is the stage where you will need your spectrometer.

i have made a file for myself to help me identify the ink limit but i'm not sure how QTRgui 
prints. in QTR for the mac, i print this file by selecting calibration mode.  this file is located 
here: http://tech.groups.yahoo.com/group/QuadtoneRIP/files/Tools/
Ink_Limit_Pattern_Page.zip

i hope this answers your question.

Quad1290-K6. Of course when I printed out the Ink limit test, the inks came out listed for 
that set - (of course). So although I now have a page with six ink level tests printed on it, 
saving this later on seems irrelevant since the names don't match - and it was designed 
for eight inks.
