The Code 11 barcode is a high density numeric barcode. Although code 11 is a higher density barcode, it requires a checksum to be calculated and can be difficult to use for non-programmers. If you are not a programmer and you need an easy to use numeric barcode, consider our Codabar Barcode Font which does not require checksums to be calculated. If your application supports ActiveX in Windows, we also sell easy to use "drag and drop" Linear ActiveX Controls that support Code 11 as well as other barcode types and they automatically calculate the checksum.

The symbology of the Code 11 character set consists of bar code symbols representing the numbers 0-9, a dash symbol, the start character and the stop character. In the code11 font, the parentheses are used for start and stop characters.

IDautomation Code 11 Barcode Fonts Main Features:

The Code 11 barcode fonts are scaleable and should be printed at the correct font size to suit your application and scanning equipment. The code 11 barcode font was designed to be printed at a minimum font size of 12 points, however, you can print smaller point sizes if your printer and scanning equipment support it. Four versions of the Code 11 barcode fonts are provided to support different width and height requirements. The last character in the Code 11 barcode font name determines the height of the barcode with the shortest being IDAutomationC11XS and the tallest being IDAutomationC11L. To determine which Code 11 barcode font to use, first print out the IDAutomationC11S barcode font at various font sizes to determine which size is the smallest that will work with your scanning equipment. Then, choose the tallest version that will fit in your scanning area. The following is sample code from Visual Basic that selects the Code 11 bar code font and size.
Printer.FontName = "IDAutomationC11S"
Printer.CurrentX = 1250
Printer.CurrentY = 4500
Printer.FontSize = 12
Printer.Print variable

TrueType fonts are supplied in PC and Macintosh format. The TrueType TTF fonts are compatible with Macintosh OS X and all versions of Microsoft Windows, including Pocket PC.

With the purchase of a Developer License and a 1 year subscription of the Priority Support and Upgrade, we can convert fonts from this package to PCL 4, Xerox Metacode, XES, FNT, BDF, FON and AFP. More about this is provided here. The Developer License also grants you the right to convert our fonts to other formats as necessary including TrueDoc and OpenType.

Also included are two PostScript versions of the Code 11 barcode fonts. Binary and ASCII versions of PostScript are also provided.

Code 11 Checksum Calculation Example:

---

To help users integrate barcodes into their applications, we provide MS Office Macros for Excel and Access, ActiveX DLLs for development platforms that support ActiveX technology, Crystal Reports User Function Libraries (UFLs) and a check digit calculation application with Visual Basic source code as a free download for programmers and technical users. The DLLs, macros, UFLs and VB code provided automatically format the start, stop and check characters to our barcode fonts.

In this example, we want to encode the data "21435" in a Code 11 barcode with a single check digit. The check digit is a modulo 11 checksum.

1. First, we determine the weights of the numbers in the Code 11 barcode starting from the right side of the number. We then multiply the number of the barcode by the weighting and add these together as in the example:

2. Barcode to encode: 2 1 4 3 5
   Weighting:     5 4 3 2 1
   Totals:      10 4 12 6 5 Then add them 10+4+12+6+5=37

3. Next we divide the total by 11 and get the remainder which is 37/11=3 remainder 4. The remainder is the check character.
4. To type or print a Code 11 barcode encoding the data 21435 that can be scanned, we need to print (214354) .
