Examination of the quality of barcode reproduction

Barcode is a kind of code in which the words, sentences or their parts, such as letters and numbers of plain text, are replaced by groups of letters or numbers depending on code replacements. Codes are used for securing confidential content (military, diplomatic, etc.). The basic theme of this paper is the functionality of barcodes after their printing on labels. For that reason, quality tests are performed with lines printed by means of two types of digital printing technologies on three different printing substrates. Contrast, blurriness and raggedness of lines were tested and compared on prints to see which digital technique and what kind of paper substrate were the most suitable for printing barcodes on labels. These three properties, among many others, define readability of bar codes. Today, digital printing is a very popular printing technique. Ink-jet and laser printing technique, also known as electrophotography, is used for printing simulated EAN bar codes.
