The kind of graphics I do are used for a web site and also for printing with a Roland Versacamm wide format printer.
My question is for graphics for a web site do you design in RGB colors and when you design for printing are you using CMYK colors.
Or are you using one type of color over the other for both purposes?
Thanks Jimmy
We had a long discussion about this earlier this year.
Personally I prefer to work in CMYK, and you've been given a few reasons why from the others.Many users prefer RGB, and it may also theoretically give a better color representation.You must remember though, that you will never be able to print all the colors you see on screen and export to web, on your Roland Printer CMYK, not even near.Therefore I suggest that you either work in CMYK from the start, which will create reasonably accurate printing results, or that you work in RGB and with Proof Colors enabled in Draw, this to simulate what can actually be printed. If you don't, you'll most likely be disappointed with the printing result.
Edit: I see now that you were the original poster in the thread I linked to. Were you not satisfied with the answer?

I would have to respectfully disagree with you on this one.
Depends on what CMYK colour space you're working in. In North America the default tends to be U.S. Web Coated (SWOP) v2. The Roland printer is MORE than capable of producing a MUCH larger gamut than that specified in the U.S. Web Coated (SWOP) v2 profile. Working in the CMYK U.S. Web Coated (SWOP) v2 colour space really restricts the output that can be achieved with the Versacamm.
The Roland Versacamm is a much different beast than an Offset Web Printing Press.

I would agree, our Roland device (depending on the media and quality of the profile) can obtain near or exceed sRGB.

I know inkjet printers can in fact produce more colors than ordinary CMYK offset printing.Would very much like to know how much though, and if RGB printing really makes what you say it will do.
Attached is a CDR (without embedded profiles because of file size limitation here), created with the default settings for North American General Purpose, which contains the profiles you've talked about.The colors are black and grey + the first ten colors from the default RGB palette.
The first problem already at this stage, is that the colors of the rectangles don't look the same as in the palette. Confusing.With proof colors On, I get a better conformity, but then everything looks almost as dull as CMYK.
Anyway, can you please correct what needs to be corrected, and then export this file to a PDF (or EPS), and tell me exactly what to do with it to print it as good as possible. Describe what you do to it, and why. If you feel like using another file, please do.
Would be interesting to see what result I can get, compared to CMYK printing, but please don't spend any time on this unless you really have some time to spare.
Jimmy, I feel your pain. I've seen that you've posted this question on at least 3 different forums that I belong to across the Internet.
For what it's worth, I agree with our resident color guru David and Dan.
We get much better (wider gamut, brighter colors) results using RGB with our Versacamm.
I wonder if your RIP could possibly be the culprit. You're not using VersaWorks, right?
I don't know enough about that subject but I'm sure someone else does. I have no experience with Wasatch ColorRip or how it processes the information it's fed

There is something wrong with your file it displays incorrectly in correlation to the RGB numbers when an object is selected I sent a corrected version along, all I did was copy ypur objects and past them onto a CD docuemtn of the same CM settings. My file is correct, I'll also post a PDF.

Your file cannot be corrected as it is corrupt, I woul duse perceptual rendering instead of relative colorimetric and I would in Vista and Windows 7 use MS WCS as the color engine, in XP use LCMS.
