CorelDraw12

When I create and print Barcode128 only of numeric characters (eg. "00000005"), created barcode is not readable with barcode scanner. I've tried with several scanners. Created barcode doesn't look like at all as barcode created with other software.

When I add non numeric character (eg. " 00000005", space is added at the beginning) I can read printed barcode.

Every field in Barcode Wizard has the same value in both cases.

Where I'm wrong?
Thank you,
Marin

I'm not familar with coreldraw's options for printing barcodes but I can tell you that EAN128 is handled differently when you have an odd number or even number of characters. Also when you add a character it changes the type of barcode. EAN128 is type C and cannot include characters. When you add a character to the barcode you change it to umm.. its either Code128 A or Code128 B, can't remember which off the top of my head, but one of them support characters.

Most industrial printers that support barcoding will change the Code 128 type from C to A/B automatically when you add a character, and as you did it at the start then you will get it as a Code128 barcode.

Also I should note that the number your providing is not a valid EAN 128 barcode. EAN isn't managed by EAN now, they're managed by G1, same company just a name change. Best bet is to look at their web site, have a gander at some example valid barcodes and try that. Remember that you must have a AI 01 at the least, I would recommend an AI 01 and AI 20.

:edit:

just realised you never actually said that your using EAN 128, just that your using Barcode128, which doesn't really exist. It will be a Code128 of type A, B or C or could be EAN128 which follows a specific structure using AI's and data no larger than 48 characters in total length which is a Code128 type C with a special C[ a the front (encoded into the barcode, not something you have to specify specifically unless it's a peculiarity of your software).

MetalSkin thank you for your input.
You are correct about BarCode128, there is Code 128 of type A, B or C.
I don’t know about EAN128 but in “normal” Code 128 there are not odd and even parity like in EAN-13 barcode.
You can create Code 128 C when you only have numeric characters (I believe that is if you have only even number of numeric characters, while creating it you take pairs of characters).
In any other case you can switch from C type to B(A) type and vice versa or you can just use type B.

That is why I’m confused with results of CorelDraw’s barcode wizard.
He is creating barcode no matter what input I’m giving to him, but in case the input consists of only numeric characters(no meter odd or even number of characters) created barcode is not readable with any scanner I’ve tried.
If the input is not valid I was expecting to give me warning or something ....

Thank you again and sorry because my english is not quit good,
Marin

Hmm... strange behavour from coral if you ask me. What are you trying to generate a barcode for? I work on and off on an open source barcoding project on sourceforge written in java. From that I can generate an image of the major barcodes if you wish. If you know java basics it would be a simple matter to generate a barcode and capture the screen shot (or generate a bitmap). Otherwise there are barcode fonts out there, though I have never liked the barcode fonts, they're a bugger to work with.
