1.  SCOPE

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

-   The enhanced 10-digit Tray Label format

-   The 10/24-digit Tray Label format

This specification is primarily aimed at mailers that are planning on
converting to the 24-digit IM tray label format for use on trays, tubs,
and sacks. Mailers that will not be participating in any of the IM
strategies may continue to use the 10-digit legacy label specification
until further notice. This document shall be used as a guide for mailers
that provide IM barcoded labels on trays 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.

This document describes two tray label formats -- 1) the enhanced
10-digit which contains the legacy 10-digit Postal Routing Barcode,
provides a more practical layout of relevant data, and paves the route
for the changeover to the pure 24-digit IM tray label format, and 2) the
transitional 10/24-digit IM tray label for use during a transition
period as label production and acceptance systems are upgraded to
produce, read, and interpret the 24-digit IM tray barcode. The
transitional 10/24-digit label bears both the legacy 10-digit Postal
Routing Barcode and the new IM Tray barcode.

The new IM 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.

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 existing10-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
existing 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. 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 tray label will allow the Postal
Service to more effectively and efficiently manage Postal Service
operations.

This newly defined IM label program is seen as a long-term strategy,
which recommends the adoption of an entirely new 24-digit IMTL 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
IMTL 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. The transitional 10/24-digit IMTL format provides
many of the additional data elements (and related benefits) associated
with the 24-digit IMTL without changing or negatively impacting standard
operating practices.

In addition, the enhanced 10-digit label provides increased visibility
of some human-readable text on the label. This leads to improvements in
the handling of mail by carriers. The font and placement of much needed
information has also been modified to enhance the rapid reading of
information on the label in conjunction with streamlining the label
design for more efficient use with various mail flows. These 10-digit
label format modifications also put the design of the 10-digit in step
with the design of the 24-digit IM tray label, thereby facilitating the
transition (including the associated training) to the 24-digit IM tray
label format.

1.3 [Transition Strategy]{.underline} --The transitional 10/24-digit IM
tray label format is accomplished by retaining the legacy 10-digit
Postal Routing barcode in its native Automatic Identification
Manufacturers (AIM)/Uniform Symbology Specification (USS) Interleaved
(I) 2 of 5 formats and adding the Internal Symbology Specification (ISS)
code 128 24-digit IM tray barcode to the same label. This transition
strategy provides the creation of a label that can be immediately
deployed within the existing Postal Service environment without
negatively impacting operational processes. Such a strategy allows both
the Postal Service's and external mailers' label production and data
acquisition systems to be upgraded to produce, read, and interpret the
new 24-digit IMTL.

While the size of some human readable text is sacrificed in the new
10/24-digit IM tray label, the two barcodes are necessary to make a
smooth transition to the pure 24-digit IM tray label format. This is due
primarily to the large number of material handling systems currently
used by the Postal Service that will have to be modified to read the new
24-digit IM tray barcode. Most major system affecting key visibility
points have been upgraded to read the 24-digit barcode. However, there
are still a significant number of smaller systems that will take longer
to make the transition to being able to read the new 24-digit IM tray
barcode and, therefore, will rely on the 10-digit barcode.

Policy guidelines on the adoption and usage of the IM 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 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 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. Sections
3.5 and 3.7 address the content of the labels and defines field
dimensions and content for the enhanced 10-digit and the 10/24-digit IM
tray label formats respectively for both Label Type 1 (6-digit Mailer
ID) and Label Type 8 (9-digit Mailer ID). Sections 3.6 and 3.8 provide
the barcode technical requirements for the enhanced 10-digit and the
10/24-digit IM tray label formats respectively. 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 Tray labels.

3.6 [10 -- Digit Barcode Technical Requirements]{.underline} -- this
section defines barcode printing technical standards, barcode content
for the enhanced 10 digit tray label format.

3.6.1 [Barcode Symbology]{.underline} -- The 10-digit barcode shall be
an Interleaved (I) 2 of 5 barcode prepared in accordance with ANSI/AIM
BC2 and the information contained in this specification.

3.6.2 [Placement]{.underline} -- The barcode is to be printed in
accordance with the layout specifications provided in 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 10-digit barcode shall extend from 0.65 to 0.75 inch
on the enhanced 10-digit label.

3.6.4 [Nominal Narrow Element Dimension (X-dimension)]{.underline} --
The width of the narrowest bar or space element within the barcode is
defined as the X-dimension. It shall be selected as a single dimension
and shall be uniform within the barcode (bar elements or space
elements).

> Enhanced 10-digit Tray Label format
>
> The minimum X-dimension or narrow element width shall be 0.012 inch
> (12 mils), and the maximum shall be 0.016 inch (16 mils). The optimum
> X-dimension is 0.015 inch (15 mils).

3.6.5 [Barcode Wide-to-Narrow Ratio]{.underline} -- The wide-to-narrow
ratio is defined as the ratio of the wide code element width to the
narrow code element width as follows:

> Enhanced 10-digit Tray Label format

a.  For barcodes with an X-dimension equal to 0.012 inch (12 mils), a
    3-to-1 wide-to-narrow ratio shall be used.

b.  For barcodes with X-dimensions equal to and extending from 0.013 (13
    mils) to 0.016 inch (16 mils), the wide-to-narrow ratio may be any
    ratio from 3-to-1 to 2.3-to-1 but shall be uniform across the width
    of the barcode.

3.6.6 [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 quiet zones shall be maintained,
one above and 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.

3.6.7 [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) is 40 percent. Reflectance shall
be measured with a Postal Service-specified reflectance meter or barcode
verifier.

3.6.8 [Printing Tolerances]{.underline} -- The maximum irregularity in
the edge straightness of any bar element is 0.3 times the X-dimension.
The printing tolerance for any (narrow or wide) bar or space shall be
+0.004 inch and shall not be not cumulative. Example 1: If an
X-dimension of 0.015 inch (15 mils) is selected, each individual narrow
bar or narrow space element on the printing of the barcode shall not be
less than 0.011 inch (11 mils) or more than 0.019 inch (19 mils).
Example 2: If the wide bar and space dimension of 0.045 inch (45 mils)
is selected, each individual wide bar or space shall not be less than
0.041 inch (41 mils) or more than 0.049 inch (49 mils). The symbol
construction is based on AIM/USS-Interleaved (I) 2 of 5, therefore the
barcode shall comply with ANSI/AIM BC2 requirements.

3.6.9 [Quality]{.underline} -- All barcodes in each mailing shall
measure the minimum symbol grade A, B or C as specified in INCITS
182-1990. At least 70 percent of the barcodes shall measure ANSI grade A
or B, and none of the remaining portion shall measure lower than ANSI
grade C when measured with a 10 mils aperture (0.250 mm) in light in the
red spectral range between 630 and 675 nanometers (nm). For all printing
processes, it is strongly recommended that the symbols be tested to
ensure that they meet these specification requirements.

3.7.1 [Printer Line]{.underline} -- The Printer Line field is an
optional field that allows the mailer, the printing agency or label
production system to print extraneous information as specified in Table
XIII. Labels printed at the Topeka Label Printing Center (LPC) shall
contain information associated with the label order.

printed in the Printer Line field shall be allowed on any other part of
the label.

Within this area, the information may extend to the right print edge but
shall not encroach on the clear zone to the right of the 24-digit IM
tray barcode. A clear zone of at least 10 times the X-dimension of the
24-digit IM tray barcode shall be maintained between the text and the
barcode at all times. This clear zone shall also satisfy the space
reflectance requirement as specified within section 3.8.1.6

There are no font or size restrictions for information printed in this
area. However, text that resembles any other postal generated fields
such as a day of the week or a USPS air stop code may not be used in
this area; the following text - AADC, ADC, SCF, 3 Digit, 5 Digit,
Directs, Firm/ Firms, PO Box - shall be specifically excluded. This
includes any abbreviations, alphabetical, or direct variations of these
identifiers. Barcodes for a mailer\'s internal use may not be placed in
this area or anywhere else on the label, unless pre-approved on a
case-by-case test basis by USPS Engineering.

3.8 [10/24 Barcode Technical Requirements]{.underline} -- This section
defines IM Tray Label 10/24 barcode printing technical standards.

3.8.1 [10-Digit Barcode on the Transitional 10/24-digit Label
Format]{.underline}

3.8.1.1 [Barcode Symbology]{.underline} -- The 10-digit barcode shall be
an Interleaved (I) 2 of 5 barcode prepared in accordance with ANSI/AIM
BC2 and the information contained in this specification.

3.8.1.2 [Placement]{.underline} -- The barcode is to be printed in
accordance with the layout specifications provided in section 3.7 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.

3.8.1.3 [Height]{.underline} -- Barcodes shall be printed in accordance
with the layout specifications provided in section 3.7 of this document.
The height of the 10-digit barcode shall extend from 0.65 to 0.67 inch
on the transitional 10/24-digit EDL format.

3.8.1.4 [Nominal Narrow Element Dimension (X-dimension)]{.underline} --
The width of the narrowest bar or space element within the barcode is
defined as the X-dimension. It can also be specified in inches and in
millimeters. It shall be selected as a single dimension and shall be
uniform within the barcode (bar elements or space elements).

The minimum X-dimension or narrow element width shall be 0.013 inch (13
mils) and the maximum shall be 0.015 inch (15 mils).

3.8.1.5 [Barcode Wide-to-Narrow Ratio]{.underline} -- The wide-to-narrow
ratio is defined as the ratio of the wide code element width to the
narrow code element width as follows:

a.  For barcodes with an X-dimension equal to and extending from 0.013
    (13 mils) to 0.0137 inch (13.7 mils), the wide-to-narrow ratio may
    be any ratio between 2.3-to-1 and 2.7-to-1 and shall be uniform
    across the barcode.

b.  For barcodes with an X-dimension equal to and extending from 0.0138
    (13.8 mils) to 0.015 inch (15 mils), the wide-to-narrow ratio shall
    be 2.3-to-1 and shall be uniform across the barcode.

> NOTE: If the label stock in use can correctly accommodate it (label
> width between 3.4 inches and the required maximum label width of 3.515
> inches), a wide-to-narrow range of 2.3 to 2.7 can be used if so
> desired. All specified label requirements shall be maintained.

3.8.1.6 [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 quiet zones shall be
maintained, one above and 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.

3.8.1.7 [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) is 40 percent. Reflectance shall
be measured with a Postal Service-specified reflectance meter or barcode
verifier.

3.8.1.8 [Printing Tolerances]{.underline} -- The maximum irregularity in
the edge straightness of any bar element is 0.3 times the X-dimension.
The printing tolerance for any (narrow or wide) bar or space shall be
+0.004 inch and shall not be not cumulative. Example 1: If an
X-dimension of 0.015 inch (15 mils) is selected, each individual narrow
bar or narrow space element on the printing of the barcode shall not be
less than 0.011 inch (11 mils) or more than 0.019 inch (19 mils).
Example 2: If the wide bar and space dimension of 0.045 inch (45 mils)
is selected, each individual wide bar or space shall not be less than
0.041 inch (41 mils) or more than 0.049 inch (49 mils). The symbol
construction is based on AIM/USS-Interleaved (I) 2 of 5 therefore the
barcode shall comply with ANSI/AIM BC2 requirements.

3.8.1.9 [Quality]{.underline} -- All barcodes in each mailing shall
measure the minimum symbol grade A, B or C as specified in INCITS 182.
At least 70 percent of the barcodes shall measure ANSI grade A or B, and
none of the remaining portion shall measure lower than ANSI grade C when
measured with a 10 mils aperture (0.250 mm) in light in the red spectral
range between 630 nanometers (nm) and 675 nm. For all printing
processes, it is strongly recommended that the symbols be tested to
ensure that they meet these specification requirements.

3.8.2 [24-Digit Barcode on the Transitional 10/24-digit Label
Format]{.underline}

3.8.2.1 [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.

3.8.2.2 [Placement]{.underline} -- The barcode is required to be printed
in accordance with the layout specifications provided in section 3.7 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.

3.8.2.3 [Height]{.underline} -- Barcodes shall be printed in accordance
with the layout specifications provided in section 3.7 of this document.
The height of the 24-digit ISS Code 128 barcodes as presented on the
transitional 10/24-digit IM Tray label format shall be between 0.65 to
0.67 inches.

3.8.2.4 [Nominal Narrow Element Dimension (X Dimension)]{.underline} --
The width of the narrowest bar or space element within the barcode 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 0.015 inch (15 mils) on the transitional 10/24-digit IM tray label
format.

3.8.2.5 [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.

3.8.2.6 [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.

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

3.8.2.8 [Quality]{.underline} -- All barcodes in each mailing shall
measure the minimum specified grade A, B or C as specified in INCITS
182. At least 70 percent of the barcodes shall ANSI grade A or B, and
none of the remaining portion shall measure lower than ANSI grade C when
measured with a 10 mils aperture (0.250 mm) in light in the red spectral
range between 630 and 675 nanometers (nm). For all printing processes,
it is strongly recommended that the symbols be tested to ensure that
they meet these specification requirements.

3.8.3 [Barcode Content]{.underline} -- The transitional 10/24-digit IM
Tray Label format provides a label that can be immediately deployed
within the existing Postal Service environment without negatively
impacting operational processes. The use of this label makes a
transition phase possible whereby the Postal Service and external
mailers can upgrade their label production and data acquisition systems
to produce, read, and interpret the new 24-digit IM tray label and the
associated IM tray barcode.

The transitional 10/24-digit IM tray label uses two barcode symbologies
to encrypt the data. This label format contains both the Postal
Service's legacy 10-digit Interleaved (I) 2 of 5 Postal Routing Barcode
and the 24-digit ISS Code 128 IM tray barcode. This allows the 10-digit
barcode to be associated with the unique 24-digit IM tray barcode.

However, it must be pointed out that only the first *eight* digits of
the total 10 digits contained in the 10 digit Postal Routing Barcode are
identical to the the first *eight* digits of the digits contained in the
24-digit IM tray barcode on the same label. The remaining barcode
elements/digits do not necessarily match up to the elements/digits in
the corresponding postions. 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 tray barcode. The 24-digit IM tray barcode also
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.

The 10-digit barcode on the enhanced 10-digit tray label is identical to
the legacy 10-digit Postal routing barcode in its native Interleaved (I)
2 of 5 format. Only the layout on this label has been modified in
readiness for the changeover to the pure 24-digit IM tray label format.
Similarly, the 10-digit barcode on the transitional 10/24 Intelligent
Mail tray Label format is the equivalent of the 10-digit barcode on both
the enhanced 10-digit and the legacy 10-digit tray label formats for the
corresponding barcode data.

Table XXV displays the encoded 10- and 24-digit barcode elements for the
IM 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.

+------------+----------------------------+----------------------------+

3.8.4 [Unique Barcode Requirements]{.underline}

3.8.4.1 [Timeframe]{.underline} -- The 24-digit IM 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 .

3.8.4.2 [Label Serialization]{.underline} -- Implementation of the IM
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 XXVI shows all the constant and key barcode data elements for
Label Type 1, 6-digit Mailer ID and Label Type 8, 9-digit Mailer IMTL
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™ Tray
labels prior to submission to the United States Postal Service.

All barcodes in each mailing shall measure American National Standards
Institute (ANSI) grade A, B, or C. At least 70 percent of the barcodes
shall measure American National Standards Institute (ANSI) grade A or B
and none of the remaining portion shall measure lower than ANSI grade C
when measured with a 10 mils aperture (0.250 mm) in light in the red
spectral range between 630 nanometers (nm) and 675 nm.. For all printing
processes, it is strongly recommended that the symbols be tested to
ensure that they meet these specification requirements.

60.2 [Material Tests]{.underline}

60.2.1. The following tests shall be used to verify the label paper\'s
conformance to color and opacity requirements:

a.  [Opacity]{.underline} -- The opacity of the face stock shall not be
    less than 88 percent when measured in accordance with TAPPI T425.

b.  [Color]{.underline} -- The label shall be white, and compare
    visually to Chip No. 27875 of FED-STD-595, when measured in
    accordance with ASTM D 1729.

c.  The facestock shall contain no brighteners that would interfere with
    processing on Postal Service automation equipment. The Postal
    Service encourages conformance to 30.3.23.1 in the choice of
    materials.

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.

60.3 [Performance Tests]{.underline} -- These tests verify the property
of the label by exposing samples to high and low temperatures and high
humidity.

Labels]{.underline} -- The enhanced 10-digit tray label provides a more
practical layout of the available data on the label. Nevertheless, the
barcode used on this label format is identical to the Postal routing
barcode presently used on the legacy 10-digit tray label. The same 10
digits namely, the five-digit ZIP Code, the three-digit Content
Identification Number (CIN), the two-digit USPS Processing Code, are
encoded according to the Automatic Identification Manufacturers/Uniform
Symbology Specification - Interleaved 2 of 5 (AIM/USS Interleaved (I) 2
of 5) symbology. Only the layout on this label has been modified in
readiness for the move to the pure 24-digit IM tray label format. Figure
1 depicts an enhanced 10-digit tray label representation of a Mailer to
Carrier Route label; 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.

Figure 1: Enhanced 10-digit IM Tray Label Example

30.2 [Transitional 10/24-digit IM Tray Label]{.underline} -- The
transitional 10/24-digit IM tray label uses two barcode symbologies to
encrypt the data. This label format contains both the existing Postal
Service's 10-digit Interleaved (I) 2 of 5 Postal Routing Barcode and the
24-digit ISS Code 128 IM tray barcode. This allows the 10-digit barcode
to be associated with the unique 24-digit IM tray barcode. The 10-digit
barcode on the transitional 10/24 Intelligent Mail tray Label format is
the equivalent of the 10-digit barcode on the modified 10-digit tray
label for the corresponding barcode 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 2 and 3 depict two examples of Mailer Labels.
Figure 3 depicts the 10/24-digit IM tray label representation of a
Mailer to Postal Service Plant label for a mailer with a nine-digit
Mailer ID (MID). Figure 4 depicts the 10/24-digit IM tray label
representation of a Mailer to Carrier Route label for a mailer with a
six-digit MID. 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 10 digit Postal Routing Barcode are identical to the the first
*eight* digits of the digits contained in the 24-digit IM tray barcode
on the same label.

30.2 [24-Digit Barcode Data Values]{.underline} -- Two IM 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.
