Barcode printing tips.
Always confirm that the chosen bar code symbology supports the characters you wish to encode. Keeping data on bar code symbology handy while writing label formats can help you avoid mistakes. The previous section covers the prominent features of most of the bar code symbologies supported by Cognitive printers.
Do not print bar codes in color; many scanners can't see color. Avoid printing bar codes on media that has a colored background. The background color may reduce the bar and space contrast, possibly below your scanner's detection threshold.
Always use high-quality print media, and make sure that the media is suited to the application and its environment. Use thermal transfer printing when you expect labels to be in place for extended periods, or where labels may be exposed to intense heat or direct sunlight. Use vinyl labels and rubproof ribbon in harsh environments.
Print bar codes as large as possible. Avoid printing bar codes that have less than a 10 mil minimum bar width. There are several ways to program the size of bar codes. Probably the easiest way to assure yourself that all bar codes are at least 10 mils wide is to always use a print pitch of 100 dots per inch or less, if your printer will support it (most Cognitive printers do).
Adjust printer speed and darkness for optimum label printing. These settings tend to interact to a certain degree. Reducing print speed will often improve print quality.Cognitive printers are factory set for optimum results with most popular media, but may need adjustment for different media or as the printer ages. Experiment with print darkness to find the best setting. Use a bar code verifier to check print darkness, if possible.
