[Openicc] Print and monitor Color Pipeline

[Jan-Peter Homann]

Hello John, hello list
If you want to see on the monitor a preview of the final print result, 
its much more easier and robust if the same rendering engine are used 
for both output channels.
There are several ways for creating ICC-profiles for printers with more 
than 4 channels:
- internal driver tables mapping CMYK to CMYK+X, profiling is done with CMYK
- multichannel ICC profiles
For simulating the final print result at the monitor, you need a valid 
ICC profile for the printing process, which is possible for both ways.


Beside colormanagement, the complexity of the PDF 1.5 and higher 
(transparencies) is another point to use the same rendering engines both 
for monitor and prin out, to maintain integrity between monitor and print.

I still don´t see an argument, that the usage of different rendering 
engines for monitor and printout has advantages for the users.


Best regards
Jan-Peter

Some colors are a single ink unto themselves and need to be managed individually. Some inks are UV coatings/varnishes that go over the top of other things. http://en.wikipedia.org/wiki/UV_coating
