2008 United States Postal Service

1.  SCOPE

1.1 [Scope]{.underline} -- This specification contains the requirements
for the preparation of 24-digit barcoded tray, flat tub, and sack
Intelligent Mail® Tray Labels (IM^TM^ Tray Label) to be used for
distribution processing within the U.S. Postal Service.

This document is a guide for mailers that provide barcoded labels on
trays, flat tubs, and sacks of mail, and software vendors associated
with the production of these barcoded labels so that the trays and sacks
may be processed within postal facilities using the appropriate
automated handling equipment.

***Note:*** *Mail cannot be tendered with the pure 24-digit IM Tray
label until May 2009. Manufacturers and providers of software that will
be capable of producing the pure 24-digit IM Tray label must warn their
users that they cannot use the pure 24-digit labels for production
mailings until May 2009.*

1.2 [Background]{.underline} -- As the Postal Service continues to
automate mail processing, the business need for strict adherence to a
standardized tray and sack label has become imperative. Mail processing
automation initiatives rely heavily on tray and sack labels to provide
necessary mail processing and customer related information.
Unfortunately, the Postal Service's legacy 10-digit tray and sack
barcode label format does not uniquely identify the handling unit. The
IM™ Tray label is a cross-functional business solution that expands the
legacy 10-digit tray and sack label format by adding data elements that
will not only continue to support sortation and routing, but also
establish a unique identifier on each label. The IM ^TM^ tray label
formats provide unique identification of trays and sacks in addition to
identifying the originator of the mail. These formats therefore require
mailers to use Mailer IDs assigned by the Postal Service, utilize unique
identifiers and maintain numeric serialization of these identifiers.
Without the unique identifier, the potential benefits associated with
in-transit visibility, manifest reconciliation, and automated mail
acceptance are severely diminished. The use of the IM^TM^ tray label
will allow the Postal Service to more effectively and efficiently manage
Postal Service operations.

1.3 [Transition Strategy]{.underline} --This newly defined IM ^TM^ tray
label program is seen as a long-term strategy, which ideally recommends
the adoption of the pure 24-digit IM^TM^ tray label format with a
"one-time," network-wide switchover. However, the transition from the
legacy 10-digit tray and sack barcode label format to the 24-digit
IM^TM^ tray label involves two major areas. The first area is the
conversion of all label production systems. The second area is the
extensive conversion of all mail acceptance systems and material
handling systems that currently scan the tray labels. While the Postal
Service and mailing community get prepared to begin using the pure
24-digit IM ^TM^ tray label, the Postal Service has already implemented
an interim label format - the transitional 10/24 Intelligent Mail tray
label. This interim label format will be in use while the migration to
the pure 24-digit IM™ tray label format is underway. The transitional
10/24-digit IM^TM^ tray label format provides many of the additional
data elements (and related benefits) associated with the 24-digit IM^TM^
tray label without changing or negatively impacting standard operating
practices.

Policy guidelines on the adoption and usage of the IM ^TM^ tray label
formats shall be as stipulated in the Mailing Standards of the United
States Postal service, Domestic Mail Manual - DMM^®^ (DMM).

1.4 [Classification]{.underline} -- The IM ^TM^ tray label format for
trays, sacks, and flat tubs provides the maximum amount of data for
multiple postal operations by defining the label's content by mail flow.
The mailer flow format is defined as:

> Format 1. Mailer: Customers (business mailers) providing mail to the
> Postal Service in mailer-generated trays and sacks
>
> Format 2. Inter-facility: Postal Service inter-facility tray, tub, and
> sack movement
>
> Format 3. Intra-facility: Internal plant-level processes that sort the
> mail (Postal Service intra-facility tray movement)

The Inter- and intra-facility mail flows can be broken down into various
label types representing specific processing flows, each having unique
information requirements. However, two IM ^TM^ tray label types have
been developed in support of Format 1, the Mailer Flow. One that allows
for Customers that use a 6-digit Mailer ID, and a second one that allows
for the use of a 9-digit Mailer ID.

These types have been defined as:

> Type 1 -- 6-digit Mailer ID Customer-to-Postal Service
>
> Type 8 -- 9-digit Mailer ID Customer-to-Postal Service

The Mailer IDs for Customers will be managed and coordinated by the
PostalOne! Program Management Office.

1.5 [Use of the Technical Specification]{.underline} -- This
specification provides all the necessary information for mailers to
generate Postal Service-compliant tray, flat tub, and sack labels for
use within the Postal Service. Within the context of this document the
use of the term tray label refers to trays, flat tubs, and sack labels.
The specification has been divided into logical categories to simplify
its use. Sections 3.1 through 3.3 define the type of paper, resolution
and printing tolerances that shall be used. Section 3.4 contains the
general formatting guidelines for the tray labels. Section 3.5 addresses
the content of the labels and defines field dimensions and content for
the 24-digit IM ^TM^ tray label format respectively for both Label Type
1 (6-digit Mailer ID) and Label Type 8 (9-digit Mailer ID). Section 3.6
provides the barcode technical requirements.

***Note:*** *Mail cannot be tendered with the pure 24-digit IM Tray
label until May 2009. Manufacturers and providers of software that will
be capable of producing the pure 24-digit IM Tray label must warn their
users that they cannot use the pure 24-digit labels for production
mailings until May 2009.*

The Mailing Standards of the United States Postal Service, Domestic Mail
Manual (DMM) provides the official guidelines on the mailing standards
associated with the use and production of the barcoded labels presented
by mailers. However, this technical specification shall be the basis for
all other technical guidance on the IM ^TM^ tray labels.

3.6 [24-Digit Barcode Technical Requirements]{.underline}

3.6.1 [Barcode Symbology]{.underline} -- The 24-digit barcode shall be
an ISS Code 128, subset C barcode prepared in accordance with ANSI/AIM
BC4 and the information contained in this specification.

3.6.2 [Placement]{.underline} -- The barcode is required to be printed
in accordance with the layout specifications provided in section 3.5 of
this document. Required clear zones above, below, to the right, and to
the left of the barcode shall be observed. Perforations are not
permitted through the barcode and barcode clear zones on the labels.

3.6.3 [Height]{.underline} -- Barcodes shall be printed in accordance
with the layout specifications provided in section 3.5 of this document.
The height of the 24-digit ISS Code 128 barcode shall range from a
minimum of 0.70 inch to a maximum of 0.75 inch.

3.6.4 [Nominal Narrow Element Dimension (X Dimension)]{.underline} --
The width of the narrow bar element and narrow space element is defined
as the x-dimension. It shall be selected as a single dimension that
shall be uniform within the barcode. The minimum x-dimension or narrow
element width shall be 0.013 inch (13 mils) and the maximum shall be
0.017 inch (17 mils).

3.6.5 [Barcode Clear (Quiet) Zone]{.underline} -- Two clear zones shall
be maintained, one to the left and one to the right of the barcode, each
measuring at least 10 times the x-dimension and extending the full
height of the barcode. Two additional clear zones shall be maintained,
one above and one below the barcode for its full width, each measuring
at least 10 times the x-dimension. The clear zones shall satisfy the
space reflectance requirements.

3.6.6 [Reflectance]{.underline} -- When measured in the red spectral
range between 630 nanometers (nm) and 675 nm, the minimum white bar
(space) reflectance (Rs) shall be greater than 50 percent, and the
maximum bar reflectance (Rb) shall be less than 25 percent. The minimum
print reflectance difference (Rs - Rb) shall be greater than 40 percent.
Reflectance shall be measured with a Postal Service-specified
reflectance meter or barcode verifier.

3.6.7 [Printing Tolerances]{.underline} -- The barcode shall comply with
section D1 (Dimensional Print Tolerances) of the ANSI/AIM BC4
requirements.

3.6.8 [Quality]{.underline} -- At least 70 percent of the barcodes in
each mailing shall have an overall symbol grade of "B" or better when
measured with measured with a 10 mil aperture (0.250 mm) in the red
spectral range between 630 nanometers (nm) and 675 nm. The remainder can
measure no less than a Symbol Grade of "C". Specified symbol grades are
based upon the ISO/IEC 15416 Barcode Print Quality Guideline (formerly
INCITS 182) which recommends a method of measuring the quality
parameters of printed bar code symbols.

For all printing processes, it is strongly recommended that the symbols
be tested to ensure that they meet these specification requirements.

3.7 [Barcode Content]{.underline} -- The legacy 10-digit Postal Routing
Barcode consists of 10-digits. These eight digits consist of the ZIP
Code and the Content Identification Number (CIN) information. The
2-digit Postal Service Processing Code as currently used in the legacy
10-digit Postal Routing code shall now be defined as a one-digit
Processing Code in the 24-digit IM^TM^ tray barcode. The 24-digit IM^TM^
tray barcode contains additional elements that enable the processing
status of trays, sacks, and flat tubs to be monitored throughout the
Postal Service. These additional barcode elements include the Mailer ID
and the Serial Number.

Only the first eight digits of the total 10 digits in the 10 digit
Postal Routing Barcode are retained in the 24-digit IM^TM^ tray barcode.
The remaining barcode elements/digits do not necessarily match up to the
elements/digits in the corresponding postions.

Table XIII displays the encoded 24-digit barcode elements for the IM^TM^
tray label mailer formats - Label Type 1, the 6-digit Mailer ID and
Label Type 8, the 9-digit Mailer ID. The numerals in the square brackets
represent the number of digits contained in each field.

3.8 [Unique Barcode Requirements]{.underline}

3.8.1 [Timeframe]{.underline} -- The 24-digit IM^TM^ tray barcode
creates a unique ID for each tray and sack. To maintain uniqueness of
the barcode the Postal Service requires that for both Label Type 1,
6-digit Mailer ID, and Label Type 8, 9-digit Mailer ID, the period of
uniqueness shall be between 30 to 45 days, as determined by the specific
Postal Service program office.

3.8.2 [Label Serialization]{.underline} -- Implementation of the IM^TM^
tray label impacts the existing labeling systems in that they now need
to provide and ensure a unique ID in the barcode for a specified
timeframe. Furthermore, the definition of specific barcode elements to
ensure uniqueness, lays the foundation for the exchange of information
as the tray or sack is processed through the postal network. The
serialization strategy defines how each of the label types imparts
uniqueness, in addition to how the uniqueness is maintained for the life
of the tray or sack. For each flow, uniqueness is defined in terms of
constant, key, and variable fields in the barcode. Constant fields are
those that always stay the same due to the origin of the mail and/or the
source of the tray or sack label. The key elements are elements that
vary, but not at the control of the originator. Variable fields are
fields where the originator may vary control and are the most effective
means to guarantee uniqueness. At present, the Serial Number is the only
variable field that the originator fully controls. Once uniqueness is
defined, maintaining uniqueness of the tray or sack ID for its entire
"life" is the goal of serialization management.

Table XIV shows all the constant and key barcode data elements for Label
Type 1, 6-digit Mailer ID and Label Type 8, 9-digit Mailer IM ^TM^ tray
label barcode formats.

*^1^Most* *printing systems provide a single Processing Code and as
such, this field may be a constant. Some printing systems (including
select mailer systems) are provided a contingency Processing Code.
Depending upon the nature of the use of these contingency codes (whether
a given printing system has control over when the contingency code is
used); this field could either be a key or a variable field.*

*^2^Mailer* *systems shall produce Type 1 or Type 8 labels depending on
whether a 6-digit or 9-digit Mailer ID is used; hence, this field is
considered to be a constant.*

4.  QUALITY ASSURANCE PROVISIONS

4.1 [Responsibility for Inspection]{.underline} -- The label printing
entity is responsible for the inspection and testing of all IM^TM^ tray
labels prior to submission to the United States Postal Service. The
label printing entity is also responsible for maintaining the overall
quality of the labels they produce. It is highly recommended that
inspection and testing of IM^TM^ tray labels be periodically undertaken.

At least 70 percent of the barcodes in each mailing shall have an
overall symbol grade of "B" or better when measured with measured with a
10 mil aperture (0.250 mm) in the red spectral range between 630
nanometers (nm) and 675 nm. The remainder can measure no less than a
Symbol Grade of "C". Specified symbol grades are based upon the ISO/IEC
15416 Barcode Print Quality Guideline (formerly INCITS 182) which
recommends a method of measuring the quality parameters of printed bar
code symbols.

The different symbol grades indicate print quality. Only the use of the
appropriate aperture for the X-dimension of the barcode symbol under
consideration, will guarantee that the grade obtained from measurement
of this symbol, is the correct grade according to the ISO/IEC 15416
specified methodology.

60.2.2 [Resistance to Water]{.underline} - A 16 hour water soak test
shall be performed to determine thermal paper\'s resistance to water.
Generate ten samples of imaged label stock using an Atlantek dynamic
response tester. The settings to be used are medium energy, step 10,
pattern 5. These samples shall be immersed in 22^o^C distilled water for
16 hours. Upon removal from the water, optical density is measured on
the air-dried sample and compared to the initial value. The difference
between the initial optical density and the optical density of the water
exposed sample shall not exceed more than 15 percent. The supplier shall
submit the tested samples with the test results.

60.2.3 [Curling]{.underline} - The curling test is performed at 20
percent relative humidity and 75 percent relative humidity. In each case
the temperature is maintained at 23ºC ± 1ºC (73.4ºF ± 1.8ºF). A number
of single 8.00 x 10.00 sheets of the paper stock, which have been
conditioned for 24 hours at the temperature and humidity specified in
3.3, are laid on a smooth, horizontal surface. After 24 hours, the
sheets are examined and, if necessary, turned over so that the convex
side is up. The amount of curl is then measured from the flat surface to
the highest point of the sheet. The test shall be performed at 20
percent relative humidity first and then the same sheets shall be
exposed to the 75 percent relative humidity for the 24-hour period.

60.2.4 [Resistance to Sunlight]{.underline} - The image stability
determination shall be made by exposing the thermal paper to 7000 luces
of fluorescent light for 14 days (336 hours). The difference in optical
density when measured with a Macbeth Optical Densitometer or equivalent
shall not exceed more than 10 percent between initial sample and the
light exposed sample. The supplier shall conduct the test on an
instrument of their choice; however, the supplier shall submit the
tested samples with the test results.

30.1 [24-digit IM ^TM^ Tray Label]{.underline} -- The 24-digit IM^TM^
tray label uses the 24-digit ISS Code symbology for encrypting the data.
While the label format remains constant, the human readable elements on
the label may vary as the tray undergoes the various stages of mail
preparation. Figures 1 and 2 depict two examples of Mailer Labels.
Figure 1 depicts the 24-digit IM ^TM^ tray label representation of a
Mailer to Postal Service Plant label for a mailer with a nine-digit
Mailer ID (MID). Figure 2 depicts the 24-digit IM ^TM^ tray label
representation of a Mailer to Carrier Route label for a mailer with a
six-digit MID; mailers use this label to indicate trays containing mail
that has been sorted by a five-digit ZIP Code down to the carrier route
level. A subtle difference to note in the label representations for 6-
and 9-digit MIDs is the very last digit (the 24^th^ position) in the
human readable representation of the barcoded elements. For Label Type 1
-- 6-digit MID, this digit shall always be "1"; for Label Type 8 --
9-digit MID, this digit shall always be "8".

NOTE: Only the first eight digits of the total 10-digits contained in
the legacy 10-digit Postal Routing barcode are identical to the first
eight digits of the 24 digits in the 24-digit IM^TM^ Tray barcode for
the corresponding barcode data.

30.1 [24-Digit Barcode Data Values]{.underline} -- Two IM^TM^ tray label
types have been developed in support of Format 1, the Mailer Flow. One
that allows for Customers that use a 6-digit Mailer ID, and a second one
that allows for the use of a 9-digit Mailer ID.

These types have been defined as:

> Type 1 -- 6-digit Mailer ID Customer-to-Postal Service
>
> Type 8 -- 9-digit Mailer ID Customer-to-Postal Service

The Mailer IDs for Customers will be managed and coordinated by the
PostalOne! Program Management Office.
