Envelope Margins
The following table gives typical address margins for a Commercial #10 or DL
envelope.
Note For the best print quality, position margins no closer than 0.6 inch
(15 millimeters) from the edges of the envelope.
Envelope Storage
Proper storage of envelopes helps contribute to good print quality. Envelopes
should be stored flat. If air is trapped in an envelope, creating an air bubble,
then the envelope may wrinkle during printing.
