Weighted colors in MkIV

Weighted colors in MkIV

[Wolfgang Schuster]

Hi,

in MkIV there is a problem when I set tints for a color.


This is a complete minimal example of my setup:

\setupcolors[state=start,rgb=no,cmyk=yes,spot=yes] % rgb= no needed in  
MkII

\setupcolor [hex]

\definecolor[PantoneOneEightSeven][h=C40F2F,e=Pantone 187 U]

\definespotcolor[dtkred]     [PantoneOneEightSeven][p=1.0]
\definespotcolor[dtkredlight][PantoneOneEightSeven][p=0.7]

\starttext

\blackrule[width=4cm,height=4cm,color=dtkred,]

\blackrule[width=4cm,height=4cm,color=dtkredlight]

\stoptext


I could also reproduce it with a short setup:

\setupcolors[state=start,rgb=no] % rgb= no needed in MkII

\definespotcolor[dtkred]     [red][p=1.0]
\definespotcolor[dtkredlight][red][p=0.7]

\starttext

\blackrule[width=4cm,height=4cm,color=dtkred,]

\blackrule[width=4cm,height=4cm,color=dtkredlight]

\stoptext

With the setting rgb=yes the color dtkred is correct in the output
but dtkredlight is darker than dtkred, with the setting rgb=no
dtkred is black in my document.

Hi,

can I expect a fix for this problem in the next time
or will this take longer.
