[NTG-context] MP spot color in gradient - help!
Struggling against a deadline here so apologies for no full sample.
I have a gradient fill defined using
\startuseMPgraphic{mpos:par:mylearnobj}
path p;
for i = 1 upto nofmultipars :
p := multipars[1] topenlarged 8pt bottomenlarged 8pt leftenlarged 3cm ;
color ca ; ca := \MPcolor{greenthirty} ;
color cb ; cb := \MPcolor{white} ;
sh := define_linear_shade(origin, origin shifted (120mm,0), ca, cb) ;
fill p withshade sh ;
endfor;
\stopuseMPgraphic
This works if the colour greenthirty is defined as a CMYK colour
\definecolor[TAXBgreenthirty][c=.3,m=0,y=.057,k=.069]
but, inevitably, my printer wants it defined as a spot ink, and when I
do this:
\definecolor[PantoneThreeOneFourFive][c=1,m=0,y=.19,k=.23]
\definespotcolor[TAXBgreenthirty][PantoneThreeOneFourFive][p=.3]
the gradient turns to black instead of green. (The spot colour
definition works fine in the rest of the document, just not in the
gradient fill.)
Could someone possibly let me know if it is even possible to define a
gradient using a spot colour, or if I should instead revert to some
alternative solution.
Thanks,
Duncan

I don't think so. Normally, if you use a specific color (recognizable) the printer should be able to remap that to some spot color (at least that is what we have done in the past, cf publisher specs).

Re: [NTG-context] MP spot color in gradient - help!
Right, thanks very much for the quick response Hans. I can remap colours with the tools we have here, except in the case of a gradient fill. I think I will try using a repeated graphic as a background instead, while waiting for printer's thoughts.

In PDF it’s possible, I don’t know about MP/ConTeXt. Did you check (e.g. with Acrobat Pro) if your Black is indeed a spot color? You may send me your PDF off-list. Did you try defining your spot color with RGB values? (I remember I needed that for something...) Greetlings from Lake Constance!
