Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are members of

ISO or IEC participate in the development of International Standards through technical committees

established by the respective organization to deal with particular fields of technical activity. ISO and IEC

technical committees collaborate in fields of mutual interest. Other international organizations, governmental

and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information

technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of the joint technical committee is to prepare International Standards. Draft International

Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as

an International Standard requires approval by at least 75 % of the national bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

ISO/IEC 15419 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Subcommittee SC 31, Automatic identification and data capture techniques.

This second edition cancels and replaces the first edition (ISO/IEC 15419:2001), which has been technically

Introduction

Bar code technology is based on the recognition of patterns encoded in bars and spaces of defined

dimensions according to rules defining the translation of characters into such patterns, known as the

symbology specification.

Bar code digital imaging systems must be capable of reliably converting the information to be encoded into a

bar code symbol meeting the symbology specification and application requirements if the technology is to fulfil

its basic objective. Such systems comprise two major components, namely the hardware device which

produces the physical image of the bar code symbol on paper, photographic film, printing plate, or other

substrate, and the associated software which converts the input data into digital instructions used to drive the

hardware device. Each component can take many forms and perform differing functions.

Manufacturers of bar code equipment, the producers of bar code symbols and the users of bar code

technology therefore require publicly available standard test specifications for bar code digital imaging

systems to ensure the accuracy and consistency of performance of these systems. This International

Standard is intended to lay down general principles governing the bar code image generation function in each

component, supplemented by more specific details applicable to certain major categories of software and

hardware.

4 Bar code design software
4.1 General requirements

The testing procedures in this section are intended to report the conditions under which software, in

conjunction with a printing device, is capable of producing quality symbols. The tests performed under the

reported conditions will typically be performed in a controlled setting. Ongoing verification of symbols

produced in an operational setting should be performed using the methodology contained in ISO/IEC 15416.

In addition, visual checks should be performed to confirm the correct formatting of the symbol in accordance

with the symbology and other applicable specifications. Further guidance on equipment maintenance and

supplies is found in Annex C.
4.1.1 Data input

The human-readable text and symbol characters for all symbols should, wherever possible, be generated from

the same key entry input. The software should apply appropriate formatting algorithms to meet relevant

application standards.

The input process should also allow for the input of relevant symbol parameters such as target X dimension or

magnification factor, wide:narrow ratio, and bar height, where these are user-definable according to the

symbology specification; such input shall be subject to the capabilities of the imaging or printing system, in

particular the adjustment of target element dimensions as described in the subclauses of 4.2.

Check characters for encoded data shall either be calculated or verified by the software. For example, if the

software prompts for the entry of only twelve digits for an EAN-13 symbol, the software shall automatically

calculate the check character. Alternatively, the software might prompt for the entry of thirteen digits and

indicate an error if the check character input is incorrect. The latter approach assures that valid data has been

entered.

It is desirable for the input data to be displayed when the label or layout is designed, subject to the limitations

of the display device, to enable the operator to validate it. Optionally, the software may also display the

symbol characters encoded.
4.1.2 Quiet zones

The software should indicate, either graphically or in text, the appropriate area surrounding the symbol

required for quiet zones.

NOTE In order to ensure that the minimum quiet zones are respected when printing or positioning the symbol, if for

example print growth or variations in print to substrate register are expected, adjustment of the position of any graphical

mark on the digital image adjacent to the quiet zone boundary, or of the position of the symbol relative to the edges of the

area in which, or substrate on which, it is to be printed, may be required.
4.2 Considerations by software and imaging device categories

Refer to Annex D for a review of software categories and Annex E for a review of imaging device categories.

4.2.1 Direct bar code imaging devices

This section provides software design requirements for imaging devices that create the final bar code symbol

on the substrate. This category is divided into the two sub-categories, dedicated bar code printer software and

general-purpose printer software.
4.2.1.1 Dedicated bar code printers

This section provides software requirements for dedicated bar code printers. Dedicated bar code printers

contain all of the low-level software required to generate bar code symbols. This means that various symbol

formats are stored in the firmware specific to the printer. The bar code design software simply sends

commands to address the firmware in the printer to create the symbol. These commands typically relate to

data characters, element sizes (typically expressed as a multiple of addressable dots), symbol orientation, and

symbol placement.
4.2.1.1.1 Adjustment of target element dimensions

This procedure is intended to produce symbols with a revision in the target module width of the symbol to

eliminate rounding errors. The software must be able to make adjustments to symbol character element

widths based on the output resolution specified. This means the overall symbol width will be adjusted to

produce an integer number of addressable dots consistently across all element widths. For symbols with a

fixed aspect ratio, a proportional adjustment should be applied to the module height (Y-dimension).

These adjustments should be made by rounding down to the closest integer value, provided the value falls

within the range of widths prescribed by the symbology specification or application standard. Rounding down

is preferred because rounding up could cause reduction of or interference in the area allocated to the quiet

zone. Quiet zone reduction could result from selecting a label width that is very close to the target symbol

width. Quiet zone interference could result from adjacent graphic layout images remaining constant as the

symbol width expands. When symbol module widths are rounded up, the software should clearly indicate the

required quiet zone area to the designer.

Refer to Annex F for a programmer’s example for an illustration of this procedure.

4.2.1.1.2 Record of design attributes

Digital bar code files for dedicated bar code printers are generally created for a specific printer make and

model at a specific resolution. It is wise for the party printing the symbol to create the bar code at the

production stage closest to the symbol output. When this is not possible and the digital bar code file is

transferred between two parties, certain design attributes should be communicated. The following design

attributes should be communicated for dedicated bar code printers to ensure symbol quality in the output

stage:
⎯ The output resolution specified for symbol output

⎯ The adjusted symbol module dimensions based on the specified output resolution (see 4.2.1.1.1)

4.2.1.2 General purpose printers

This section provides software requirements for general-purpose printers. General-purpose printers do not

contain low-level software for generating bar code symbols.
4.2.1.2.1 Adjustment of target element dimensions

This procedure is intended to produce symbols with a revision in the target module width of the symbol to

eliminate rounding errors. The software must be able to make adjustments to symbol character element

widths based on the output resolution specified. This means the overall symbol width will be adjusted to

produce an integer number of addressable dots consistently across all element widths. For symbols with a

fixed aspect ratio, a proportional adjustment should be applied to the module height (Y-dimension).

SIST EN ISO/IEC 15419:2010
ISO/IEC 15419:2009(E)

These adjustments should be made by rounding down to the closest integer value, provided the value falls

within the range of widths prescribed by the symbology specification or application standard. Rounding down

is preferred because rounding up could cause reduction or interference in the area allocated to the quiet zone.

Quiet zone reduction could result from selecting a label width that is very close to the target symbol width.

Quiet zone interference could result from adjacent graphic layout images remaining constant as the symbol

width expands. When symbol module widths are rounded up, the software should clearly indicate the required

quiet zone area to the designer.

Refer to Annex F for a programmer’s example for an illustration of this procedure.

4.2.1.2.2 Adjusted BWC

The printed dot width for general-purpose printers is typically larger than the measurement between the

centres of two adjacent dots (pixel dimension) as shown on the right grid in Figure 1.

NOTE Dot width equal to pixel width (left) and dot width oversize compared to pixel width (right).

Figure 1 — General purpose printer dot / pixel comparison

This enlarged dot size causes the bars to be printed wider and the spaces narrower than nominal, unless the

software driving the printer corrects for this condition. BWC is a procedure that is commonly performed during

bar code design, which compensates for the bar width gain or loss experienced in the printing process.

Adjusted BWC is the result of a procedure, which has been introduced to make BWC result in a consistent,

integer number of addressable imaging device dots based on the specified output resolution. The two types of

BWC are BWR and BWI. When print gain is anticipated, BWR is used. Adjustments to BWR should be made

by rounding up to the closest integer value. Rounding up is preferred because slightly narrower bars are

preferred to slightly narrower spaces. When print loss is anticipated, BWI is used. Adjustments to BWI should

be made by rounding down to the closest integer value. Rounding down is preferred because slightly narrower

bars are preferred to slightly narrower spaces.

Refer to Annex F for a programmer’s example for an illustration of this procedure.

4.2.1.2.3 Record of design attributes

If the printer supplies are appropriate and the printer’s operating condition is maintained, the printer should

provide quality symbols when the output conditions match the specified design attributes and the symbol has

not been distorted by importing it into a secondary illustration or page layout software package. It is wise for

the party printing the symbol to create the bar code at the production stage closest to the symbol output.

When this is not possible and the digital bar code file is transferred between two parties, certain design

attributes should be communicated. The following design attributes should be communicated for general-

purpose printers to ensure symbol quality in the output stage:
