![]() Two adjacent characters are separated by an inter-character gap. The height of the bars must be at least 0.15 times the symbol's length or 0.25 inches, whichever is larger.Ĭode 39 is a discrete symbology. Also 3 out of the 9 elements are always wide. It is called code 39 or three of nine because each encoded character is made up of 5 bars and 4 spaces to make a total of 9 elements. The Code 39 barcode uses four special characters "$", "/", "+", and "%" which allow a full ASCII character set when paired with alphanumeric characters.Ĭode 39 is designed to encode 26 upper case letters, 10 digits and 7 special characters:Ī, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z Three of the nine elements (bars) are wide and six elements are narrow. The principal feature is that it encodes messages using a full alphanumeric character set. Code 39Ī stop character – the second asterisk (*)Ĭode 39 is of variable length and is the most frequently used symbology in industrial bar code systems today. The reduced size is 80% of the nominal size. The nominal height for the EAN-8 bar code is one inch. The EAN-8 is fixed length and is similar to the UPC-E code, but includes two more digits for the country code. Stop guard bars, always with a pattern bar+space+bar Last three characters, encoded in character set C The following two characters, encoded with character set AĬenter guard bars, with a pattern space+bar+space+bar+space Two number system characters, encoded with character set A The nominal height for the EAN-13 bar code is one inch. The codes 00-04 and 06-09 have been assigned to the United States. Also, the 12th and 13th digits of an EAN-13 may represent a country code in its entirety or just the beginning of one, and can vary from 2 to 3 digits. The EAN/JAN-13 is of fixed length and is similar to the UPC-A symbology, but encodes a 13th digit. Start guard bars, always with a pattern bar+space+barĬentral guard bars, always with a pattern space+bar+space+bar+spaceĮnd guard bars, always with a pattern bar+space+bar The left guard bar is encoded with 101, and the right guard bar is encoded with 010101. The nominal height for the UPC-E bar code is one inch. UPC-E symbols are UPC-A symbols that have been zero suppressed (that is, consecutive zeros are not included in the symbol). The printed value of the UPC-E code is a twelve-digit code. UPC-E (Universal Product Code-E) is fixed in length and is a compressed six-digit code used for marking small packages including magazines and paperback books. Stop guard bars, always with a pattern bar+space+bar. Left half, five digits calculated from the equivalent UPC number. A magnification factor of 0.8 to 2.0 is permitted and, as a result, enables a printable X dimension values range of 10.4 to 24 mils. Usually, the number system digit is printed on the left of the barcode, and the check digit on the right while the manufacturer and product codes are printed just below the barcode, separated by a guard bar.īoth the left and the right guard bar are encoded with 101 (bar space bar). This means that any hardware or software capable of reading EAN-13 is automatically capable of reading UPC-A. ![]() ![]() In fact, a UPC-A barcode is an EAN-13 barcode with the first EAN-13 number system digit set to "0". The usual height of a UPC-A bar code is one inch. The final digit is a check digit, which cannot be omitted. It encodes a twelve-digit numeric only number. ![]() UPC-A (Universal Product Code-A) is of fixed length. Start guard bars, always with a pattern bar+space+bar.Ĭenter guard bars, with a pattern space+bar+space+bar+space.Įnd guard bars, always with a pattern bar+space+bar. For more detailed information on the symbologies of barcodes, refer to professional barcode technical documentation. This appendix briefly describes each one. JReport Designer supports ten types of barcodes: UPC-A, UPC-E, EAN-13, EAN-8, Code 39, Code 128, Code 128A, Code 128B, Code 128C and Codabar.
