Spot color with custom RGB and CMYK profiles

[darriusw00]

I have one map I want to use for print and web. In an ideal world I could create a custom spot color with a CMYK (0,0,0,7) and RGB (web 242,242,242) profile. Is this possible? I'm not happy with the way illustrator ic converting my colors.

The color percentages are not "profiles".  A Spot Color is a specific color used in printing, not for web use.  What do you mean by "converting".  As far as getting colors to look the same in print vs. your monitor, that is not easy.  Is it possible?  No.

What Im looking for is a way to set a color to appear one way in print (CMYK) and another for web (RGB). For example, I have a gray at RGB 242,242,242 for web, but for print I need it to be darker, so I'd like to be able to customized the swatch. When I change the "color mode" ai turns RGB 242,242,242 to CMYK 3.71, 2.46, 2.46, 0.  I want RGB 242,242,242 to CMYK 0,0,0,7.

Everything about colour management is designed to defeat your plan.

New approach (no idea if this is possible):

Can I define the color of an object and stroke in the styles menu and then link that style to an ase file. Then when I need to make an edit, I only have to work with one file and when exporting confirm I have the correct ase colors selected??

Guessing the answer is no, but I have to ask.

What makes you unhappy about how colour management converts the colours? Are you using the correct CMYK profile for your output conditions? Are you using a calibrated monitor?

My monitor is calibrated but my office printers are unreliable and these maps will be used by multiple people in multiple departments. I can build a map that looks correct on screen, and a map that will compensate for the printers, but but these maps will take weeks to develop and if possible I'd like to avoid creating two versions.

Office printers - with PostScript? If not, the CMYK will be converted back to RGB for printing anyway...

Printing to a Xerox WorkCentre 7845.

Why would a printer convert a CMYK file to RGB if it has CMYK toner?

That is how both Windows and Mac manage non-PostScript printing. Can't stop it, so your conversion to CMYK (unless it's PostScript is pointless and adds another unknown; maybe one reason you find printing unreliable. Use tagged RGB and the results should be fairly consistent.
