Things can go fugazi if you don’t treat your address labels right. I don’t mean you should talk sweetly to them and buy them candy and jewelry and take them out on expensive dates. You need to keep them out of the sun. Really, many times you don’t realize it, but labels can come in contact with direct sunlight sometimes when you leave them out on your desk, and your desk happens to be near a window. If you wouldn’t leave your beer in direct sunlight, why would you do that to your labels. Even worse, don’t forget to close your windows (if you’re fortunate enough to have opening windows at work), when you go home for the day. One winter, our building got a little too warm, so we opened up some windows. Somebody, ahem, forgot to close a few windows. That night there was a big snow storm. When we came in that morning, there was a snow drift on a couple of desks. You don’t know how weird it is to see a snow drift in the office. Needless to say, snow is not good for labels. Any kind of moisture will affect label performance adversely. So keep your address labels, shipping labels and really, any kind of labels in a nice dark storage closet, not to humid, not to dry. Your labels will last longer, look better, and you’ll be happier.
