paper dust As saw dust is to wood, paper dust is to paper. It is made up of
loose paper fibers and other residues which naturally accrue to
paper. Controlling paper dust is a serious issue for the Xerox
MICR printing system in terms of extraneous ink spots.
peaks & valleys,
waveform
Represent the “highs” and “lows,” or in the magnetic waveform
signal patterns of the MICR characters.
perforated paper Paper pierced with one or more rows of small holes to permit
easy tearing off or separating into sections.
permanence Also called “archival property.” A measure of how long a sheet
will last without becoming excessively brittle and yellow. The
permanence of a sheet is directly related to its acidity. Also refers
to the degree of adhesion of an image to the paper and the
ability of a MICR image to retain its human and machine
readability over the normal life cycle of a check.
personalization The relatively recent concept in MICR printing for including non-
MICR variable data on the documents (e.g., council rate notices
with MICR encoded deposit slip attachments. (UK))
phantom Any light image placed on a document, usually for decorative
purposes. The subject is intended to be printed or written over
and is generally lightened by means of screening.
pigments Substances used to produce color or different degrees of
whiteness in paper. Sometimes pigments are coated on papers,
which can cause contamination problems in printers.
photoreceptor In laser printers, a drum or belt device with a light-sensitive
coating, which converts an optical image into a latent
electrostatic image on its surface.
pH Chemical measurement of level of acidity or alkalinity in paper or
other substances.
porosity Measurement of the ability of air to pass through a sheet of
paper.
portrait Refers to the printing across the width of a page (letter style).
This is the opposite of landscape orientation, which is printing
across the length of the page. The term portrait is derived from
portraits of people, which are usually vertical in format.
post-encoding Amount field encoding of deposited items prior to the receipt by a
bank.
predrilled paper Paper having two or more holes drilled along one edge, for use in
ring binders or notebooks.
pre-encoding Amount field encoding of deposited items prior to the receipt by a
bank.
