Wilma,
Thee are two classic uses for Relative WITHOUT Black Point Cimpensation.
1. Converting CMYK for proofing when stock colors match between
simulation device and simulator.
2. Converting an RGB reflection scan to CMYK when the dynamic range of
the original is equal to or less than that of the CMYK device, and the
most faithful reproduction is needed.
In virtually all other cases BPC should always be on.
Don

Hi Eric,
Keep in mind that ImageControl isn't cheap. Only printers with deep
pockets
can afford such offerings.
I, personally, have yet to complete a full calibration and profiling
cycle
on this very piece of equipment. But I can tell from my humble
experience
with HDM products that they are very, very well thought of. There is
a level
of integration in their products that no other "printing" company in
the
world can match -- from prepress workflows, to ICC profiling, to
process
calibration (including gray balance), to plate making, to presses,
binding
and finishing equipment. I think the only thing HDM doesn't offer is
paper.
But otherwise, it's a complete offering. Anyone walking in the door
of this
company can literally find everything under one roof.

Hi all and a Happy New Year!
I have just been looking at the workflow on the Heidelberg site, and
am mightily impressed. Even if the robot voice over can't actually
say
Heidelberg (how did that get through!). Seriously the explanatory
videos are great and should be required viewing for all printshop
owner and print room operators.

age_control,overview
I was wondering if anyone has personal experience of this system and
whether it does indeed live up to it's claims. If it does it looks
like anyone with a sheet fed Heidelberg has got colour management
sorted!
Eric

Hello
What are the situations in which the relative colorimetric rendering
intent should be used without black point compensation?
Thanks
