Gluing — Sticking With Direct Mail

Layout Considerations
If a form with side-by-side envelopes is being used, don't have the glue strips rest against each other as they're coming off the machines. Unintentional adhesion can occur when glue strips are directly in contact with each other face to face, especially during shipping. Staggering designs so that glue strips avoid contact with each other is a much better way to plan a job.
