Preparing a document for printing I would like to convert a logo, which is completely white, into an image, in which the white colour is replaced with a spot colour "lack" (for UV coating).
I added this colour "lack" to the colour space (Edit > Colours).
I tried to do this outside of Scribus (in GIMP), but the imported image doesn't display anything, maybe because I chose the wrong file format. Is there a way to achieve this in Scribus directly?
