Both. One must be very careful when choosing inks to avoid such artifacts. Even in 4->8 separations. So, is common practice to sacrifice some of theoretical gamut extent in order to avoid that. Anyway I'm still learning about this subject :-) Regards, Marti. ----- Original Message ----- From: "Gerhard Fuernkranz" <[EMAIL PROTECTED]> To: "Marti Maria" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Wednesday, May 19, 2004 3:36 PM Subject: Re: [Lcms-user] Understand color matching inside Inside printer driver > At least for HP ones, the normal operation is to use an output > profile in CMYK and then a devicelink for the 4 to 8 separation. > It is quite possible to do a output profile directly operating > in 8 inks, but may generate "bubbles" in the gamut hull, that is, > zones no covered by any ink combination. Marti, do you really mean isolated holes _inside_ the gamut solid, or just "dents" in the surface (i.e. only a non-convex outer surface)? I'm curious, have you actually seen such isolated holes in practice for n-colorant (n > 4) profiles? Thanks, Gerhard -- "Sie haben neue Mails!" - Die GMX Toolbar informiert Sie beim Surfen!
