This may be of no use to anybody ..... but

If I want to see if there is a colour shift from RGB to CMYK for printing (after all the printer prints in CMYK) if I go to export in Corel then ask to export in CMYK, it show the colour shift. In some colours nothing noticable in this colour pink....... a huge shift!

Don't need to do the export just watch the display change.

The colours that your printer can produce are dictated by the inks in it, and the ICC that you are using. So, although your screen can produce lots of fantastic colours, your printer can't. Even more so if you are using sublimation inks with a generic profile. A custom made ICC profile will help you get the best (most possible colours) from your inks, but there will still be some that you can't do.
Paul has similar charts as the one in post #4 which also shows achievable colours from some sublimation inks compared with full RGB/CMYK.

Thanks Pisquee
In a nut shell I have learned today that certain colours have limitations, and essentially those are the ones that leap out, lime green, bright pink, and some ends of the red spectrum. Interesting reading!

I find that (like was posted earlier) you can't print/reproduce bright pink or a really good vibrant lime green in print. I can't do this on either my Ricoh or my Roland Versacamm. I could do it if my Versacamm was the one which prints metallics/white as it has a pearlescent print capacity which gives the vibrancy to the colours. So from a bog standard printer it looks like it's not possible.

whatever you do you WILL not be able to print bright, eye poping colors. new icc wont help in this. it help to achive more colors but not the bright ones.

Thank you but I think you might mean Paul? Or another Justin maybe? lol.

barbie pink is out of gamut

Do a google search, in images, for Barbie pink and there's loads of different shades - just do it magenta, its close enough. You'll never get it as bright as your screen - its impossible, as other have said.

Question for Paul, would a printer with light magenta help at all getting a better pink for something like this?

quick answer: I DONT KNOW
But more ink shades in printer definitely will let you get more colours out of your gamut. Justin may confirm that as he is very touch about skin tones on photographs. and he is noticing quite large difference.
