Guaranteed Barcode Printing Quality Original film customization is the key

First, enterprises should have a certain understanding of the technology and equipment level of the original film production unit, and it is best to order it from a specialized agency to ensure the quality of the original barcode film.

Second, when coding, the complete EAN-13 code consists of the manufacturer identification code, product item code, and check digit. The product item code is compiled by the company itself and is organized in strict accordance with the "one product and one yard" in the form of a serial number to facilitate enterprise management.

Third, the size of the original bar code of the barcode is related to the magnification factor of the bar code. The zoom factor actually refers to the size of the product barcode. Too large a product barcode will occupy too much space for the packaging pattern or the printed text, which is not practical; if it is too small, it is likely to cause difficulties in printing and reading. Therefore, the size of the bar code should be appropriate, usually based on the size of the outer packaging of the product and the area allowed for printing, the magnification coefficient selected for the bar code on the outer packaging of the product should be within the range of 0.8-2.0, and the general amplification factor should be 0.9- 1.2, for the 0.8-0.9 bar code symbol, quality control is more difficult and should be used with caution.

Fourth, the choice of the original film positive and negative: the same with the printed bar code symbol brightness and darkness is positive, negative otherwise. Normally, the positive film of the original bar code symbol is drawn by a laser drawing device, and the negative film is copied by the positive film. According to the needs of the selection of the visual printing process, the general principle is: to make a letterpress and a planotype, and to choose a negative film; to make a gravure, an intaglio plate, and a stencil (such as a screen plate), and to select a positive film.

Bar code original film use and preservation should pay attention to: Do ​​not scratch, scratch the film; if the film deformation due to special reasons, etc., should not continue to use; bar code original film plate should be preserved, ready for the next plate printing.

5. The company should have a person responsible for the management of the original bar code of the film, and will do the archiving and preservation of each film, to facilitate the addition of new products in the future, so as to avoid duplication of code.
