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
