Comment créer un profil colorimétrique CMJN sans noir dans les couleurs ?

Bonjour


Ma question est la suivante : sous Photoshop sauriez comment créer un nouvel espace colorimétrique (CSF) à partir d’un profil ICC précis ?
Mon but est d’avoir un espace colorimétrique personnel basé sur un profil ICC étranger et de le modifier de façon à ne pas avoir de noir dans mes couleurs pour travailler de manière plus confortable. En gros avoir un espace colorimétrique qui transforme de lui même en CMJ n’importe quel teinte CMJN choisie dans le sélecteur de couleur.

 

Merci d'avance

A litho method for printing color images without black (but usually with a gloss varnish) was in use for a short time a little over fifty years ago, primarily for producing a small-quantity of picture post cards economically. The process was referred to as "Pleasing Color" but about the only thing that was pleasing was the price. Minor variations in ink film thickness on press caused significant color shifts in the three-quarter and shadow values in the images and I never saw one with a neutral rich black.

Thanks for the idea , Norman, but in this case I'm not into litho. Have a nice weekend 🙂 !
