More questions! I'm using black plus one spot colour in a document, and I include PDF images generated in an external program (CorelDraw) which use the same spot colour. In the images the color is called 'PANTONE 294 CV', but I can't use that name for my colour in ConTeXT because names can't contain numbers or spaces. So in ConTeXt I define \definecolor[PantoneTwoNineFour][c=1,m=.56,y=0,k=.18] The end result is a file with two spot colour spaces instead of one. Is there a way I can combine them, either by a last-minute renaming, or a mapping, or a pre-process, or something? (I tried the brute force method of search-and-replace on the PDF file but there must be binary-encoded references to the names as well as ASCII ones, because that broke the file.) Any help as ever greatly appreciated. Duncan
