Envelope Acceptable print quality can only be assured when printing in
those areas of an envelope where there are only two thicknesses
of material. In the following figure, the upper diagram shows
the varying material thicknesses present in an envelope.
See the lower diagram for:
Recommended image area: The cross-hatched area should be
used for printing the address of the recipient. Optimum print
quality is achieved in this area.
Shaded areas: These areas represent the areas that can
be used for the address. This recommendation is based
on the requirements of high-speed optical character
recognition (OCR) equipment used by most post offices.
The larger shaded area can contain the delivery address;
for example, post office (city), state/province and zip/post
code. The narrow, darker shaded area may contain the name
of the recipient.
