Hi,

just playing around with spot colors and run into this problem.
tested with 23.04.2012 and ??.11.2011, same result. the color definition
leads to an invalid pdf.

% multitone.tex----
\nopdfcompression
\setuppagenumber[state=stop]
\definemultitonecolor[combicolor] [blue=.12,yellow=.28]
[c=.1,m=.1,y=.3,k=.1]

\starttext
\null
\stoptext
%------------------

I also attached the original example (spot.tex).

Best wishes,  Peter
