I have two questions that I need to sort out
1. Before you profile an RGB printer you need to calibrate the printer
for good settings. What should you look for? A printed image that pleases
your eyes with nice colors, a nice smooth greyscale or should you get a
setting that put out as much inks it can without bleedings, any suggestions
to determine the best settings and can you use readings for it instead of
using the eyes as you do with the profiles?
2. Can someone elaborate more how you create a linear curve in GCR? (se
text below) Were do you start in the separation settings in PM5 or are there
futures that Monaco profiling has and not Gretag?
To be able to get a print that not only reads neutral but looks neutral.
Instead of clipping densities in the separate channels you can get the same
affect by creating a linear curve in the GCR (grey component replacement)
field of Monaco when creating the profile. So instead of trying to reach a
neutral image with CMY and very little black, you replacing much of the grey
component made up of CMY(LcLm) with K(Lk) and just enough C(Lc) to offset
the yellow tint of the K and Lk inks. This is to compensate for the yellow
tint of the K. Now the image reads neutral and the color shift is far less.
Thanks
Soren
