Variable Printing!

Most people order envelopes with just their return address printed in either the upper left corner of the face or in the center of the envelope face or even on the flap. Did you know that we can also print your recipients name and address in the delivery area of the envelope? Well, we can and it is called variable printing. In fact, we can print almost any kind of variable data on your envelope. You can have us print Names & Addresses, Serial Numbers or Member Numbers. We can print most any kind of data that needs to be different on each envelope. All we would need from you is an Excel file filled in with the information you want printed on each envelope and we can take it from their.

RUSH Printing Options!

In general, custom printing takes 5 to 7 days to complete. But we do feel that you need to know that shorter quantities (100 or less) will be printed much faster and larger quantities (10,000 or more) will take longer. We almost always offer a RUSH printing option where you can choose how fast we will print your envelopes. Please keep in mind that RUSH printing will NOT automatically give you a faster shipping method. We are still constrained by the standard shipping times offered by the Post Office or UPS. You can, in additional to requesting RUSH printing, also request faster shipping options.

Each Custom Blue #10 Window Envelope features a standard commercial flap with diagonal seams. Suppliers build these products with 24# pastel colored paper. This is a smooth yet durable material for envelope construction. The transparent Poly-film window measures 1 1/8" x 4 1/2" with 7/8" from the left and 1/2" from the bottom. To use, simply insert your mail through the flap located on the long-side of the envelope (booklet-style) and use the standard gum seal to secure. This seal does require moisture to become adhesive.
