Hi Terry,
GCR effect?
I think that what is called "GCR Effect" is directly related to what
most popular profilers used to generate as far as quality when using
GCR.
Lowering the TIL without loosing saturation and details in shadows
depend on which software you are using (how GCR is calculated).
Tests with other profiling softwares showed they cannot go lower than
about 260.
It is a good thing that other profiler(s) (PerfX, etc.) now do a
better job and make people understand that GCR CAN make good
separation with low ink coverage!

For anyone else who may respond, I told Louis that I used the
Gracol dataset to create profile in Profilemaker with MaxGCR and
320TIL, that is what we've been using here. Now when I do the same
thing but lower the TIL, the K percentage goes up, so it seems that
lowering the TIL actually increases the GCR effect?
At what point, do you think, lowering the TIL would begin to
adversely affect the darker or deeper colors?
Thanks for any input,
Terry Walker
