Our Offset Envelopes are printed on 70 lb. smooth white opaque paper. After the envelopes are printed in full color, they are die-cut, machine folded and glued together. The result of this process is a beautiful envelope that can be printed on both the front and back sides. Our high-end envelopes are strong and vibrant in print color. Your logos, dramatic gradients, and detailed photos print incredibly accurately on our envelopes. These Offset Envelopes are available in a wide variety of sizes and offer a great first impression of your company when you are mailing to your special clients.
