Metering & Sealing
Postage Applied. Ready to Mail.
High-speed postage metering and envelope sealing — the final step before your mail enters the USPS stream.
What Is Metering & Sealing?
A postage meter is a USPS-approved machine that prints a postage indicia (the red digital mark showing postage paid, date, and ZIP code) directly onto envelopes or adhesive strips. Sealing wets and closes the envelope flap simultaneously. Metered mail is one of the most efficient ways to apply postage for large volume mailings and is accepted for all first-class and standard mail classes.
Metering is the application of digitally-printed postage to mail pieces using a USPS-approved postage meter. Sealing is the simultaneous moistening and closing of envelope flaps. Catdi Printing's high-speed mailing machines meter and seal thousands of pieces per hour — the last step before our postal runs. Metered mail shows a digital ink impression with the postage amount and mailing date.
