Publisher you need an engine to convert PMS values in eps files t.

[Robert Owen]

We get alot of Publisher files that are supplied to us with RGB colors. About
50% of the time we're asked to print those in spot colors on the press. So,
we'll convert the spot colors to PMS values to proof on our Canon Laser
Copier to give the customer a fair look at what they're piece will look like
when printed vs. their inkjet copy printed with RGB images. The fiery
controller for the CLC does a right fair job of simulating PMS values. The
problem I have with Publisher is when I use an eps with said PMS color
embedded it won't let me print CMYK composite. Microsoft needs to work on
this. This is a valuable step in our workflow since it's extremely hard to
show a customer a grayscale laser proof and describe how the colors will
change on press vs. showing them a color proof that's reasonably accurate.

can't you use the color tools to change the rgb to spot, making sure to
sue the proper colorname from the eps, then print seps and then make
your proof from this--letting the rip recombine the colors and all that
stuff.

I've been using BestColor for just this for years. A Harlequin rip can
do similar, ripping it into a composite cmyk tiff file...that you could
p[ass on to your Canon.

 

[Robert Owen]

Changing the colors to the spot colors described in the eps give me
separations just fine. I'm able to send these seps to my platesetter for
printing on press no problem. Publisher however can't handle the printing of
the eps in a cmyk printing model. Even greyscale composites screen the pms
black. This is something that should be addressed in future versions. Quark,
Pagemaker, InDesign, etc. all handle this without incident. Additionally I
haven't looked too deep into this, but, I see no way to apply my printer
profiles to Publisher files. I appreciate Microsoft's attempts to conform to
commercial printing workflows, but, color management certainly needs to be
addressed.

Thank you for the Bestcolor tip, I'll look into it.

Most EFI Fiery rips for color copiers have a "combine separations" option in
the print dialog box. If your CLC has that option, then in theory you
should be able to print separations to the CLC, enable the combine
separations and it should print a composite with the correct colors for the
EPS. I haven't tried it myself with our Doc 12 but I think it should work.

Interesting idea. However (this is an oddity I hadn't discovered yet) when I
try to print separations to my Canon I get the same error as though I were
printing composite. I can print separations to my HP using a PS driver and I
can send separations to my platesetter (also PS) but Publisher won't print to
the Canon at all unless I delete the EPS's containing the PMS info. Curiouser
and Curiouser.

Maybe a level 3 EPS while the CLC has a level 2 rip?

It's definitely a level 3 rip, but, an interesting idea anyway. I tried the
original level 2 eps sending level 3 and 2 in postscript options. And
re-saved eps's as level 3 and tried again. No luck.

Which Canon? Is it one with a Fiery, or one of the ones with a Canon PS
interpreter? Our experience is that a Canon interpreter can get choked by a
file that will RIP without problem on a Fiery, even an older model.
