A print-only vendor delivers printed sheets, forms, or components. A lettershop completes the work required to mail them, including folding, inserting, matching, addressing, sorting, and tray preparation. Using one plant for both reduces handoffs and keeps matched mail, quality control, and USPS entry on one schedule.
A press date is only one part of a mailing schedule. Inserting, matching, postal documentation, and tray preparation must also finish on time for the planned USPS entry date.
