Dear List,

I defined the following color for one of my documents: \definecolor[P][r=0.64,g=0.22,b=0.27]
When I printed this document on a probably typical office laser printer (a Canon iRCXXXX), the 
colors didn't match. (not even close and I didn't like the printed color) This is probably no real 
surprise, but can anybody provide some insight or hints to information on these matters to me: 

 -- Are "spot colors" the thing to use to get a grip on these matters?  
 -- Is this generally only a matter of "color spaces" and transformations between them?  or ...
 -- Is this also dependent on specific printer models (eg. different office laser printers)?
    -- If yes, is there any source on information on the pecularities of these printers?

kind regard and thanks

Erik
