When I create an EAN-UCC 8, EAN-UCC 13, EAN-UCC-14 or RSS-14 bar code, LABELVIEW appears to be changing the data string after I close the bar code configuration dialog box. Why is this happening? |

LABELVIEW 7.05 features 2005 Sunrise bar codes. Some of the new features to the bar codes may be a bit confusing for users unfamiliar with 2005 Sunrise but already familiar with LABELVIEW.
The four 2005 Sunrise bar code symbologies available in LABELVIEW 7.05 are:
- EAN-UCC 8
- EAN-UCC 13
- EAN-UCC 14
- RSS 14
2005 Sunrise is a data requirement that requires all users worldwide to use a 14-character data stream for retail bar codes. LABELVIEW 7.05 is more flexible in how it handles data input for the 2005 Sunrise bar codes.
For example, if you have a system that currently creates EAN-8 bar codes, the data string of fewer than 14 characters (in this case 7 or 8 characters) will be changed to a 14 character (2005 Sunrise-compliant) string in LABELVIEW by padding the value with leading zeros to ensure that the data string complies with 2005 Sunrise requirements.
If you are using a data string of more than 7 characters, LABELVIEW will automatically modify your data string to use the correct digits from the string to create the bar code. LABELVIEW will also truncate the last character and calculate its own check digit if there are more than 7 characters in the second half of the string.
Therefore, if you create an EAN-UCC 8 bar code with:
- 7 numeric characters: LABELVIEW pads the beginning of the string with zeros, but the bar code displays the 7-digit value without the leading zeros. LABELVIEW also calculates the check digit for this string, which is displayed as the 8th numeric character.
- 8 numeric characters: LABELVIEW removes the last character and displays the first 7 characters along with 7 padding zeros. In this case, LABELVIEW truncates the 8th character and calculates the check digit based on the 7 characters.
- 13 numeric characters: LABELVIEW replaces the first 6 characters of the data string with zeros, and the last 7 numeric characters are used for the bar code. LABELVIEW calculates the check digit for the 8th character.
- 14 numeric characters: LABELVIEW replaces the first 6 characters of the data string with zeros, and the next 7 numeric characters are used for the bar code. In this case, LABELVIEW truncates the 14th character and calculates the check digit for the 8th character.
