MS Office Forum / Publisher / Commercial Printing / January 2005Publisher you need an engine to convert PMS values in eps files t.
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[a.s on to your Canon. > 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 [quoted text clipped - 9 lines] > change on press vs. showing them a color proof that's reasonably > accurate. 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. > 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 [quoted text clipped - 4 lines] > do similar, ripping it into a composite cmyk tiff file...that you could > p[a.s on to your Canon. 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. Jeff Daghir MPS Printing, Inc. The Ink & Paper People!

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.

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. > Maybe a level 3 EPS while the CLC has a level 2 rip? > [quoted text clipped - 8 lines] > > Curiouser > > and Curiouser. > Interesting idea.

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. -------------------------------------------------------- Chris Griffiths email: chris@stroudprint.co.uk StroudPrint phone: 01453 764251 Gloucestershire, England fax: 01453 752916 -------------------------------------------------------- I v y d e n e A s s o c i a t e s L t d -------------------------------------------------------- |
