<Do you have something like what Imageprint does in mind? If so, I would
like to know how Imageprint creates those grayscale profiles. I just
<want to know if it is something possible to do with regular profiling
tools, I don't necessarily want to know something of a "I could tell
you but then I have kill you" nature.>
The grayscale workflow in ImagePrint is a separate pipeline in the RIP.
ImagePrint does not simply kill the yellow carts and profile like a
regular printer. I don't know how its done internally so to speak, the
overall attempt was to create a very small gamut B+W workflow with
minimal metamerism problems.
<The gray ink in these
printers has a warm tone, to varying degrees, depending on the media
used. By
balancing that yellow tint out with C&M inks, any tone that is not more
yellow
than the gray ink on that particular paper can be achieved without
adding yellow
ink, thus offering a range of low metamerism black and white options.
This
is possible with any RIP that offers the necessary ink controls, and any
profiling software that allows you to draw appropriate black curves, but
you need
to roll your own with most RIPs, instead of having it done for you. With
ColorBurst, for example, it is possible to build device configurations
of this type,
and distribute them for use with the RIP and a given printer and
inkset.>
I'll believe it when I see it, and so far I've not seen it translated
from their (insert RIP vendor here) mouth to a killer B+W print in my
hand. ImagePrint has had this B+W ability for over a year and it works
very well. Other vendors claim it's nothing special but can't replicate
the versatility, simplicity, or performance. Ditto for the 2200 which
has been supported forever by IP, they wrote the 2200 code from scratch
while everyone else continues to wait for Epson to release tidbits of
code and libraries. When I see prints roll off the printer from a
competitive software that look as good or better I'll be a more
interested. I always find it funny that people tear into ImagePrint for
its RGB profiling but are completely lost when it comes to finding an
optimal black generation curve. Am I supposed to randomly draw black
curves and make 100 prints, or should I use Colorbyte's values that were
created specifically for the Ultrachrome inkset and already tested for
optimal performance? You can't talk most pro photographers into jerking
around with RIPs for days, they don't make a living building profiles
and none of them buy this equipment to waste their time with. I do want
to play around with Studioprint but that will have to wait for a rainy
day.
