Subject: Re: [Homebrew_PCBs] Forcing printing of Magenta or Cyan from RGB in Windows

Hi,

Basically you can't really! They are completely different colour spaces.
At home we print/scan/view on our montiors using RGB (Red, Green, Blue).
In commercial printing they use CMYK (Cyan, Magenta, Yellow, Black(K)).
You might be able to get close to pure Cyan or Magenta with the RBG inks.

For a full description try here:

http://en.wikipedia.org/wiki/CMYK#Comparison_with_RGB_displays

Personally if you need to print CMYK then have a look at photo printers as
they print in the CMYK space. (It's oldish but to prove a point have a look
at the Epson C82)

Hope this helps...

Kind regards,

Andy
