What is a postage meter?

A postage meter is a machine that is used to produce evidence of postage on a mail item. A postage meter imprints indicia (distinguishing marks) on your mail that serves as an alternative proof of payment to stamps.

OEM Alternatives provides high quality postage meter inks that meet or exceed both OEM specification and meet Canada Posts approval.  Postage meter ink must contain special chemicals to be recognized by the postal system authentication process and not all inks are created equal.  Don’t leave your mail printing needs to question and make sure you always use quality inks and cartridges from reputable manufacturers.

For more information on the exact specification of postal meter inks please read the specifications and information as set out by Canada Post below.

Postage Meter Ink Specifications

1. General

The purpose of fluorescent tagging is to enable appropriately designed machines used in
CPC Mail Operations to determine the presence of the indicia on standard lettermail
items and, by means of this information, to perform facing and cancelling operations.

2. Ink Specifications
Subject to the approval of CPC, any phosphor which complies with the requirements of
this specification may be used.

Note- tag recognition systems at CPC are arranged to
respond to the light emitted by fluorescent (as opposed to
phosphorescent) chemicals.

The predominant wave length of the irradiating UV light is 254 nm

Tagging phosphors and their manner of application shall not cause excessive abrasion to
mail processing equipment.

The current standard for measurement of tagging signal intensity is Starbrite paper (E.B.
Eddy Co. Ltd.). When excited by UV light and detected through a 580 mm sharp cut red
pass filter (such as the Fuji light filter SC-58 or equivalent), the intensity of the emission
from a given area of tagging must be at least 10 but not more than 20 times the intensity
of the emission (as background noise) from an equal area of Starbrite paper or card. This
comparison is termed Signal to Noise Ratio (SNR).

Phosphor tags must maintain a minimum 10:1 SNR (or better) for a least one year under
the storage conditions.

Temperature: 23 +/- 5 degrees C
Humidity: 10 to 95% RH

The format of postage meter impressions is subject to Canada Postal Guide Part 1. All
postage meters must employ approved, non-toxic, fluorescent inks which should be
applied in such a manner as to yield best possible density and clarity of impression.

It is the responsibility of the postage meter supplier to ensure that the fluorescent inks
they supply meet all applicable health and safety requirements.

The fluorescent ink used for current meter impression designs shall generate a minimum
of 10:1 SNR (ore better) to ensure successful detection of all metered mail in the CFC.

Metered mail is not stored for any appreciable time before forwarding, thus the specified
period for maintenance of adequate SNR (min 10:1) of an actual impression shall be at
least one month.

When fluorescent ink used to replenish inking rolls or reservoirs in postage meter,

a) the ink shall not settle or change its SNR over a period of at least one month and,
b) the ink when printed shall yield a min. 10:1 max 20:1 SNR over a period of at least
one month.

3. Exposure to the Public:

The postage meter tapes will be fully exposed to the public during use. Therefore, all
components of the ink, tapes and release liners shall be free from toxic chemicals and
shall be harmless to the public.
