BarCode, Code 128 size

Jmartin

Hi,

I am trying to find the fitting size for a barcode on a preprinted label in code 128.

Unfortunately, if I use BarWidth of 0.12 it's to small and BarWidth of 0.13 it's too big.

See linked image below.

I also tried to use a police in code 39, but it's too small and no scanner can read it.

My versions are :
Delphi version : Tokyo 10.2
ReportBuilder version : 20.02 Build 67
Operating System : Windows 10 21H2
Printer model : cab EOS2/300

Can you help me generate a barcode that just fit inside 2.1 x 0.75 cm ?

Thanks in advance for you help.

Hi Jean,

BarCodes must to adhere to the specification defined for the symbology (BarCodeType).

Code128 details are here

https://en.wikipedia.org/wiki/Code_128

The BarWidth and WideBarRatio properties provide a limited amount of control. The values for these properties must be within the range defined by the BarCodeType specification.

For Code128 there are 3 different encodings that can be used. By default TppBarCode.AutoEncode is True, but you can set to False and manually encode as defined here

Hi Nard,

Thanks for the hint, I guess I could try to make use of Code 128 Character Set C, to reduce the length.

Will try it soon.

Have a nice weekend.

Hello Nard,

I have encoded my value manually in Code 128 Character Set C :

BarCode1.Data := Chr(208) + 'S2' + Chr(204) + '302093000002';

This code works, the barcode is 2 mm shorter, but still to long. Do you think there is a way to make it shorter ? I don't see it.

Thanks,
Jean

Hi Jean,

Decreasing BarWidth property will result in shorter length. For Code 128 TppBarCode defaults BarWidth to 0.254 mm. Perhaps check your barcode reader for definition of valid range. I tried Google but did not find a definitive answer.
