Hi I am creating a two colour print (two seperate plates) for printing onto a plastic timber wrap. The colours are orange and green. On the clients logo part of the graphics are aproximently 50% of the main orange colour. I need to make this from the base colour to avoid doing another plate. Could someone please advise me on how best to do this using a PC and Corel Draw X4. I have an Idea it is using half tones but I am not sure how to go about this. If any one could help it would be apreciated.
