Hello all, I am trying to create a curve for a R2400 and HW Matte 
paper. I have printed the inkseparation page but am having 
difficulties determining what percentage to use for the next step. The 
instructions say to determine at what point the inks cover the paper 
and the pattern disappears. It never does for the light light black 
ink. Has anyone created curves for the 2400? Should I ignore the light 
light black ink and base my decision on ink density of the light black 
ink instead?

Thanks so much....

Dan.

Dan,

For the ink separation page you should base your decision on the PK or MK
ink not LK or LLK.  After you determine where the black ink (PK or MK) tops
out you set the Ink Calibration at that percentage (usually around 75-85%)
and print the separation test page again.  Then you determine the density of
each ink in relation to the next darker one.  See page 13 of Tom Moore's
User Guide.

Hope that helps a bit.

Tom,

this is a different dan.

thanks for the clarification. 

i've always wondered about this part of the procedure because i think the instruction's 
wording on the mac os x side seem to imply that i should identify the ink limit of each ink. 
eventually i've decided that the instruction was referring only to K ink's limit. identify this 
limit and then print the ink separation again for the next step, the ink partitioning. when i 
got this straighten out everything else fell into place.

Yes, I should have said I was speaking from the PC side of things but I
assume the Mac side is done the same way.

Tom, Thanks so much. I did read it, guess I misunderstood. Will read 
again. Really appreciate the clarification!

Also check out the Calibration pdf in the download area for a more 
detailed description than in Tom's guide.
