would depend a little on how much the different types (cmyk , rgb , pms) were intermixed.... say all were in a jpg together you would have to have a compromise on colors .... if some had raster effects and gradients again more compromise, but it was say a jpg background with pms vector logos on top and some cmyk vectors...
in flexi i can set the individual colors of the color palette to render in different manners... (you would have to do your vector designs in flexi for that though ugh!)
you can also set different rendering intents for cmyk vectors, rgb vectors, cmyk bitmaps, rgb bitmaps..etc.. in the RIP settings.
i have run into problems with illustrators drop shadows with the different rendering settings.. by default in flexis RIP rasters are set to perceptual and illy's drop shadow is a raster effect and is render as a raster so if i had a vector above another vector object and a shadow (that would look great inside illy) the shadow once printed would be a square area with a lighter color and the shadow in it...
How can you expect to match PMS on a $10K digital CMYK printer?
what about the epson CMYKOG printer?
These PANTONE Colour Look-up Tables (LUT) are developed by Pantone, Inc for the Kyocera TASKalfa 500ci Series to generate the closest possible simulation of each colour by this printer. By following the enclosed instructions and importing these colour LUT’s to specific desktop publishing software, you can generate PANTONE colours with this printer.
PANTONE® Colours displayed here may not match PANTONE-identified standards. Consult current PANTONE Colour Publications for accurate colour.
Oh I forgot, did they send you a hard proof to match the rgb and cmyk images too?
How does one match to 5 individual companies PMS colours along with RGB and CMYK images in the same artwork? At the same time keeping all parties happy while getting paid.
Salmoneye thanks for pointing that out.
Print on our Epson GS6000's, relative/relative and name the PMS colours in the .eps or .pdf file so the ErgoRip picks them up ans replaces them from it's look up table...do it everyday.
I don't disagree but it's still only a simulation and you can only match 90% of the PMS colours in CMYKOG. There's no getting around that, regardless of the intent you use.
So the client will have to settle on those 10% that do not match as a compromise because there is no other practical way of running the job. Which was my opening argument.
In theory CMYKOG will 'match' well over 90% of your srgb color space and 94% of Pantone Solid Coated Colours...I haven't came across a PMS or any colour for that matter printed on the Epson that wasn't an acceptable match apart from the metallics and such of course.
I know it may sound like BS and I was very sceptical of this printer myself before I actually saw it with my own eyes after having used CMYK, CMYKOG and CMYKLcLm and even CMYKMmMcLmLc printers for years.
The Roland CMYKOGLcLm printers also did a great job of PMS colours but the only ones I used were waterbased until I converted Mimakis to CMYKOG solvents...they were good, but not a patch on these new Epsons that have the LcLm and tiny drop size.
EDIT: Actually the Hexachrome gamut falls somewhere between srgb and Adobe98 - pretty good in anyone's book.
