[edit] Information Density

what sort of information density can you get with code 128? Could I print 'War and Peace' on a single page? Funkyj 21:38, 15 December 2005 (UTC)

Not by a long way. If you wanted to do something like that, you'd go to a 2 dimensional barcode, and even then a reasonable target would be to get the text on a form onto a 2D barcode that occupied 1/3 of the form. For dense print like a novel (leaving aside whether W&P is denser than most) I think you'd get a less favourable ratio. Midgley 11:15, 26 April 2006 (UTC)

[edit] 128b vs128c

What is the difference between 128b and 128c?

The data that 128C can print allow 0-9, A-Z, a-z and special characters. 128C can encode only numeric data. This restriction allows that two number can be encoded with one barcode symbol and reduce the barcode size. For instance, the barcode length of the number "1234" coded with 128B is twice the length of "1234" coded with 128C.

[edit] External links

I've added two links that are very useful for people that want to create their own codes, namely C routines for checksum calculation and the actual bit pattern (which in this format can't be found elsewhere on the net). Unfortunately someone keeps deleting those links. I'm reverting the page again. 17:28 BST 24. Oct. 2006

Please refer to the Talk:European Article Number page for the relevant discussion. --Millbrooky 16:52, 24 October 2006 (UTC)

[edit] Clarify a sentence.

This sentence needs clarifying: "One error in 2-5 million reads with a checksum using 6.6 wide (2 dots wide) using the 300 dpi printer on the thinnest line of the barcode" —Preceding unsigned comment added by 209.183.18.156 (talk) 00:48, 18 April 2008 (UTC)

[1] Does ISO/IEC 15417:2007 further replace GS1-128? —Preceding unsigned comment added by Crammer101 (talk • contribs) 15:52, 2 June 2008 (UTC)
