[Scribus] Legal debate on Groklaw on spot colours
Wed Aug 17 11:21:31 CEST 2005
Thanks, too for an interesting read.
There is a lot of confusion about this issue.
If there is anything at all that can be copyrighted
by PANTONE then this is the relation between
the code and a color.
Scribus does not need to implement this at all to support
spot colors (including PANTONE).
What needs to be done in Scribus is that the user is able to
create colors on custom-named plates. The physical color
this plate is finally printed with is arbitary and can be
agreed upon beforehand say by telephone with the print shop.
Of course, if the user enters "PANTONE 486 CU" as a color name,
there is no need to phone the print shop, because it will know
which color has to be used. This name is not stored anywhere in the
Scribus application but entered by the user so there is no infringement.
If you look at that color on the screen or print on your home printer
which does not know about plates but only prints CMYK, the computer does not
know the equivalent RGB/CMYK color, so for custom plates a
proxy color must be defined. Most commercial apps make it a bit easier for the
user by automatically setting this equivalent color. If you select PANTONE
486, the proxy color is CMYK red. Implementing this last thing - and only
this - is what might get Scribus in trouble here because at this point the
connection between the color name and a certain color out of the gamut is
made. If Scribus lacks this feature, this is not really a problem, because
in the end (i.e. in final production) the equivalent proxy color is not used
and can be set to anything which closely resembles the inteneded color.
Hope this clears it up a bit.
