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.

Dan.
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.

Also I would use sRGB when designing as it is most likely closest to what your printer can reproduce.
So, I made a couple of quick tests.
Printed the PDF you sent, David, using the sRGB color profile on my Mimaki JV33 CMYK printer and RasterLink RIP.I also created a CMYK version (converted the color swatches to CMYK, using the U.S. Web Coated profile in Draw) that I printed with the very same CMYK profile.The printed results were quite similar to what was seen on screen if "Proof colors" were enabled, just as expected.Compared to the vivid colors when "Proof colors" were off, the colors were not even in the same country, also as expected.
There is a slight difference between the printed results using RGB and CMYK, yes, but they are much more similar to each other than to the original RGB colors.
PS. They were scanned on an ordinary office scanner and downsampled because of file size limitation, but I think you get the picture.No color profiles embedded for the same reason, so make sure you use the correct profiles.

On my way out the door but wanted to put this on your plate. Attempt using sRGB instead of Adobe RGB in your CorelDRAW file and print to the device with a PDF with embeded profile with the device set to uses the embedded profile.
You may find that the device is now closer to what you see on screen with using sRGB.

Ronny Axelsson said:What would be the difference if I use the same profile from the PDF versus preinstalled in RasterLink?
Raster Link needs to know what the source profile of incoming files is. If it does not know it has to assume something, the version of Raster Link I worked with did use embedded profiles, not sure about your version. What version do you use?
If Raster Link assumes a source profile of Adobe and you use sRGB than the color will be saturated, the reverse happens if the assumption is reversed.
