Labels
Label construction
When selecting labels, consider the quality of each component:
● Arrangement: Only use labels with no exposed backing between
them. Labels can peel off sheets with spaces between the labels,
causing serious jams.
● Curl: Prior to printing, labels must lie flat with no more than 13
mm (0.5 in) of curl in any direction.
● Condition: Do not use labels with wrinkles, bubbles, or other
indications of separation.
Envelopes
Envelope construction
Envelope construction is critical. Envelope fold lines can vary
considerably, not only between manufacturers, but also within a box
from the same manufacturer. Successful printing on envelopes
depends upon the quality of the envelopes. When selecting
envelopes, consider the following components:
● Weight: The weight of the envelope paper should not exceed 105
g/m
2
(28 lb), or jamming may result.
● Construction: Prior to printing, envelopes should lie flat with less
than 6mm (0.25 in) curl and should not contain air. (Envelopes
that trap air may cause problems.)
● Condition: Make sure envelopes are not wrinkled, nicked, or
otherwise damaged.
● Sizes: From 90 by 160 mm (3.5 by 6.3 in) to 178 by 254 mm (7 by
10 in).
