Even though you have selected the appropriate colors in your design, it is important to let the printer know which colors are used where. You can do this by marking up a printed example of your design…simply label each PMS color with its reference number. Again, it’s a good idea to get a proof so you can approve the colors before the entire job is finished, which are much more likely to appear as you expected if you use the Pantone Matching System.
