Applying Bar Code symbols onto packaging There are two ways to apply the Bar Code symbol to your item: * using pre-printed labels * printing directly onto the package Labels A printer or label service can print bar code symbol labels, or if equipment is available, your company can print them on site. Ask equipment suppliers for a demonstration of on-site Bar Code symbol printing equipment. This equipment automatically generates the Bar Code symbol directly from data. On - site direct printing on packaging On - site printing equipment is also available which allows you to print the Bar Code symbol directly onto the package during the manufacturing, packaging, and distribution process. Printing on packaging at source Printing directly on packaging at source may require a film master. A film master is a negative or film (much like a photo negative) of the entire Bar Code symbol. The film master is applied as part of the artwork of the package. Film master suppliers generate film masters. They can also calculate the check digit for you before they produce the film master. The printer incorporates the film master on the printing plate ready for printing on the package. Either the manufacturer of the printer can order a film master. Contact EAN Australia for a list of film master and equipment suppliers. > Determine whether to print the Bar Code symbol on labels or directly onto packaging.
