Just like any printed piece of literature the image and the colors start to fade after awhile. This can be due to prolonged exposure to sunlight ot bright lights in the shop and some even think that it is due to ozone. Whatever the cause they do fade and your PANTONE FORMULA GUIDE could be incorrect and possibly cost you a re-run if you're the printer that used the old guide to print the new job.
Make sure you have the latest guide especially at the counter where your customer will order and view the job. Make sure all of your sales staff has the most up to date version as well. Remember it only takes a little too much magenta or not enough cyan to totally change the color of the ink...better safe than sorry !
