Bar Code Printing

One of the most commonly applied bar code in packaging is the GTIN-14 Interleaved 2 of 5 (also known as I 2 of 5). A few features about GTIN-14 I 2 of 5:

  • 14-Digit I2OF5
  • ITF-14 is the GS1 implementation of an I2OF5 format to encode a Global Trade Item Number (GTIN)
  • Minimum height 1.25”
  • The target bar width ratio is 2.5:1, meaning that the wide bars are 2.5 times the width of the narrow bars.
  • While the preferred bar width ratio is 2.5:1, the acceptable range is 2.25:1 to 3:1.

This ends up looking like this:

The thick bars that you see around the outside are known as Bearer Bars. The purpose of Bearer Bars is to equalize printing plate pressure. Bearer Bars also prevent short scans. They end up costing companies a lot of money to print as outlined below:

  • 100% with full bars, 300 DPI, using the FoxJet ProSeries 768
  • How Much?
  • .014 mL = 35,507 prints/bottle

Obviously, this begs the question, Can Bearer Bars be removed? The answer is mostly. You are allowed to remove the sides and reduce the top and bottom (2X width of small bar). What is known as the Quiet Zone is also removed saving more ink.

The end result is this.

How much did we save?

By minimizing the Bearer Bars while maintaining 300 DPI and scanability…

  • .009 mL = 54,444 prints/bottle)
  • Versus the original…
  • .014 mL = 35,507 prints/bottle)

This is a savings to our customers of 35%!

An important thing to remember with bar codes is their decodability. Decodable means that a scanner can read the barcode. The R.V. Evans Company guarantees decodability provided the system is installed and maintained to standards outlined by our vendor FoxJet.
