I can't wait to enlighten you. ;-) The moment you add an alpha channel (if you do that while you have an active selection that will become the content of it, like if you 'select color range' one particular color in your full color image and then press the 'new channel' button in the alpha layers palette) and double click on it, you can choose to make it a spot color (I guess it is called that). It acts like a press film, black is 100 color, white is none. Now paint or paste or mix away (that 'channel mixer' adjustment layer suddenly makes sense) and when you do a 'save as' you will see the DCS 2.0 available. I think Adobe Illustrator, Adobe InDesign and QuarkXpress are compatible with the format. The only thing is, if you (still) work in Quark, it will only print the file in seperations, for printing to a black and white composite or color printer it will skip the pic. The solution for this is a bit of a slight tricky thingy, because you can not change the document from multichannel (that is what it is yes) to, say, rgb or cmyk. In the alpha channel palet menu, you can 'split channels', you then get different documents, one for each color you use. Change them from grayscale to monotone, choose the color they represent (it is in the name they are given) and make sure it is just a straight from 0 to 100 graphic. Now change them to rgb or cmyk. In the layers palet, do 'duplicate layer' and choose the other color (or shift-drag, to get the layer pixel-perfect to match with the other. Set the layer to multiply. Flatten image. Name it imagenamePREVIEW and use that for printing or pdf's from Quark. Good luck!
