I have created some vector drawings for the web or electronic viewing only. I now need to convert some of this stuff for print and when I convert from RGB to CMYK, the colours lose their vibrancy. and when I'm converting, I no longer have the picker to work with.
Can someone help? ... please and thanks.
Thanks.

Since RGB has 16.8 millions colors and CMYK only 64.000, the difference is easy to understand. btw a correct color profile will produce a better change, according with the material and system of printing. But the brilliant and luminous colors of RGB will loose bright when you convert to CMYK

This is an dangerous advice. Some RIP can convert from RGB to CMYK, suing their internal color profiles, but not all do it, and not all have this option enabled. On almost all case, if you send a, RGB image the result will be a pale image, without bright, color and contrast...If you are not really sure that the RIP has this feature, never send an RGB image. On 99% of the time the result will be wrong

Every pixel in a true color image has 256 possible values for each of it's red, green or blue components (in the RGB model) or cyan, magenta, yellow and black (in the CMYK model).
This means that a 24 bit (3 x 8 bit) RGB image can have 256 x 256 x 256 possible combinations or 16,777,216 possible colors.
Each pixel in a 32-bit (4 x 8 bit) CMYK image is one of 256 x 256 x 256 possible colors x 256 variations of black. This is an awful lot of colors but in Draw we are limited to 100 steps instead of 256, which makes the number of possible combinations smaller (still though; 100,000,000 colors, theoretically).The color space is the same though, but as mentioned, much smaller than the RGB space anyway.
