Here are the official ITF-14 Specifications. All measurements are in millimetres.
The top and bottom bearer bars are mandatory, whereas the vertical bearer bars are optional as long as a non-printing plate method is being used.
The specified magnification range for an ITF-14 Barcode Symbol scanned in a General Distribution Scanning environment is between 50 and 100%. For other scanning environments, the range is 25-100%
If printing onto corrugate fibreboard, the ITF-14 should be above 62.5%.
Height of Bars:
The minimum height for the bars in a General Distribution Scanning Environment is 32mm.
In other scanning environments, the bar height should be as high as possible. 13mm is the minimum bar height. Hence all ITF-14’s should exceed this height. However, every effort should ensure that the height is as close as possible to 32mm.
Bar Width Ratio:
The bar width ratio is 2.5:1. The acceptable range for this ratio is between 2.25:1 and 3:1.
Human Readable Interpretation:
Font, font size and location are not specified. However, these should be printed clearly in proportion to the rest of the barcode. It is preferred for the font to appear below the barcode.
|Magnification||X-Dimension||Width||Bar Height||Quiet Zones|
All measurements are in millimetres.
It is best to allow more space for the quiet zones than the minimum in ink spread.
General Distribution Scanning Environment refers to automated scanning by a machine as the item passes along a conveyor belt.
Other Scanning Environments – Typically, this refers to handheld scanners.
Bar Width Ratio – this refers to the ratio of wide modules to narrow modules in the ITF-14. A wide module should be 2.5 times the width of a narrow module.
Quiet Zones – Area of white space on either side of the bars
